Chemistry Homework Help

Your solution for chemistry homework help.

Chemistry is a natural science subject known to confuse even the most steadfast of students. The labs tend to be especially challenging because they require a strong foundation of math, especially error analysis. But chemistry is also a vast discipline. This means that once you learn one aspect, you have to switch gears and learn another. For example, acids and bases are mostly separate from equations and stoichiometry.

Branches of Chemistry Homework Help

You don’t have to be in a particular chem class to qualify for our help. Our tutors can lend a hand with any course, including organic chemistry homework. In fact, we’ll list here all the branches in which we can deliver timely and quality assistance right when you need it.

Organic Chemistry We receive a lot of chem homework help requests in this area. In a word, organic chemistry is tough. It studies the structure, properties, and reactions of organic compounds and requires a significant amount of time. With our chemistry assignment help online, you’ll soon grasp the concepts of this course.

Inorganic Chemistry This field concerns the properties and behaviors of inorganic compounds, including minerals and metals. If memorizing new terms is causing brain fog, turn to StudyGate for chemistry homework help.

Physical Chemistry The subjects of physics and chemistry meet here to study the physical properties of atoms and molecules. This is an extremely intense course. That’s why many students seek chemistry assignment help online.

Analytical Chemistry The purpose of analytical chemistry is to determine what matter is and how much of it exists. This is no easy feat, however. Our chem homework helpers are always available to answer questions.

Biochemistry Biochem explores the chemical processes of living organisms. This requires a great deal of laboratory time. The purpose is to understand and solve complex biological problems. To do this, you need to first understand the subject. StudyGate is happy to offer biochemistry assignment help online.

Environmental Chemistry It’s easy to confuse this field of study with green chemistry because they both aim to help our planet. But environmental chem studies chemical processes within the air, water, and living environments. Green chemistry seeks to reduce pollution at its source. With our chemistry homework help online, you can better understand both fields.

Industrial Chemistry This field improves lives by transforming matter into useful materials. But you don’t have to study these ideas on your own. Give us your question and receive rapid chem homework help.

Sample Question and Answer for Chem Homework Help

Seeing is believing, and that’s why we’re providing a sample chem question and answer here. We want you to know our tutors are capable, and the same chemistry assignment help they’ve provided in the past can also be given to you.

Predict the product for the following reaction, paying attention to stereochemistry where appropriate.

Chemistry Assignment Help Online from Qualified Experts

Most students emerge from an academic background of seeing facts, repeating them for homework, and regurgitating the same facts on a test. But in chemistry, it’s important to understand the meaning behind those facts so you know the appropriate ways to use them.

Our chem homework helpers pave the path to this knowledge. Chemistry factors enormously into our daily lives, including the cleaning solutions we use, the air we breathe, and even the foods we eat. Using practical examples like these, our team can explain homework questions and turn an impossible assignment into one much more enjoyable. And if a piece of the puzzle still doesn’t make sense, we invite students to schedule online tutoring sessions.

Benefit from Long-Term Learning

Working one-on-one with a tutor allows you to plan sessions when it’s convenient for you. You can also use this opportunity to study to greater effect. For instance, as you’re reading classroom text in the time before your session, highlight those areas that aren’t clicking. Then ask your tutor for clarification. This is a much better way to learn than reading difficult material by yourself and later trying to remember it for an assignment or quiz.

We can also teach students the steps necessary to successfully solve chem problems. This requires more than memorization. Students need to devote a little time each day getting to know the subject. Slowly but surely, the procedures that characterize chem will start making sense. And thanks to the added knowledge of our chemistry homework helpers, you’ll breeze through the rest of your course and earn an awesome grade.

The Best Chem Homework Help from a Qualified Team

Chemistry homework help should come from those who have great time management and presentation skills, are patient, and can clearly show their work. StudyGate ensures each of our team members demonstrates these qualities before onboarding them. We work with only the best – pros driven to ensure your success.

Students can either answer a question immediately or study further before answering by clicking on the Resources tab to go directly to the appropriate section in the e-book. Each problem provides help in the form of hints, targeted feedback and detailed solutions to ensure every problem provides learning through practice.

Insight Cards

Insight cards provide quick views of student work in a just-in-time way keeping what is important and current right at the surface! You can drill down for more detailed views to see individual student or whole class performance.

Instructor Activity Guides

The IGC instructor activity guides were built around the Interactive General Chemistry text and interactives. Each activity guide provides at-a-glance metadata to make it easier to prepare and implement. Instructors can pair "preflection" assignments with follow-up reflection supported by pre-built clicker slide decks and/or reinforce student learning with post-activity homework assignments to follow up on the in-class activity. These flexible resources support a variety of teaching styles all emphasizing student engagement.

Interactives & Worksheets

IGC worksheets were designed to work seamlessly with a set of Interactive General Chemistry interactives. The worksheets can be used for in-class or virtual group work or individual work outside of class.

iClicker Integration

Prebuilt iClicker slide desks assist with instruction and help to easily facilitate reflection on activities, allowing instructors to check understanding and get feedback in real time. In addition, iClicker seamlessly integrates into the Achieve gradebook.

Faculty Resources

Assignments.

The assignments in this course are openly licensed, and are available as-is, or can be modified to suit your students’ needs. Available answer keys will be provided to faculty who adopt Waymaker or OHM courses with paid support from Lumen Learning. This approach helps us protect the academic integrity of these materials by ensuring they are shared only with authorized and institution-affiliated faculty and staff.

If you import this course into your learning management system (Blackboard, Canvas, etc.), the assignments will automatically be loaded into the assignment tool.

You can view these faculty-contributed assignments below or throughout the course.

Discussions

The following discussion assignments will also be preloaded (into the discussion-board tool) in your learning management system if you import the course. They can be used as is, modified, or removed. You can preview them below:

Optional Reading-Based Discussions

If you wish, you can include the following prompt to encourage students to complete their reading and discuss class topics with their peers.

Discussion Board Standards

It is expected that students will complete the assigned textbook readings prior to posting responses to the discussion board. Student interaction is encouraged. The goal of these online discussions is to simulate the sort of group discussion that can occur in traditional classroom settings. Therefore, students must post comments to at least two classmates. In addition, the instructor may post their reaction to student comments.

The instructor will assess the quality of student contributions towards group discussion and determine a grade for each unit/chapter.

• Student discussion must be relevant to the specific question being discussed.
• Students should demonstrate their understanding of the issues, theories, and problems from their textbook readings and homework. Good student commentary will make reference to specific textbook readings and make use of the terminology introduced in the chapter.
• Students should respond to the discussion questions with an attitude of proper objectivity and a willingness to discuss matters with others who do not share their viewpoint. Criticism of theories or ideas is appropriate; however, the tone of this criticism should remain scholarly rather than personal.
• Students are encouraged to make use of examples and counter-examples, compare and contrast theories, make reference to past learning, indicate problems or difficulties they have with the theories, and draw out the relevant implications of the discussion.
• Students may also raise questions they have about the readings and discuss possible answers provided these questions are relevant to the topic of the discussion.

Consider the discussions as opportunities to share ideas about this exciting material with your classmates—enjoy this!
