This video discusses genetic variants. The video explains how DNA codes for proteins and how variations in the DNA sequence can lead to alterations in the amino acids and shape of the protein produced, which can lead to changes in the...

In this live-action program viewers will learn that scientific disciplines, such as Earth Science, Biology, Chemistry, and Physics, are based on observation and experiment. Students will come to understand that the first line of defense...

Learn the basics about solubility rules for insoluble salts, as part of the overall acids, bases and alkali topic.

Choral Director Simon Halsey explains why Beethoven's Ninth is not supposed to be comfortable for the chorus.

The video explains the process of protein synthesis, how information from DNA is used to build complex protein molecules from simpler amino acids, and how the order of bases controls the order in which amino acids are assembled,...

👉 Learn how to simplify expressions by multiplying its terms. When multiplying expressions, each individual term of the expression is multiplied to its like term and the exponents are evaluated using the product rule, the quotient rule...

👉 Learn how to solve exponential equations. An exponential equation is an equation in which a variable occurs as an exponent. To solve an exponential equation, we isolate the exponential part of the equation. Then we take the log of both...

In this video lesson we will learn about powers, exponents and bases. We will understand that a power is represents a base and an exponent where the exponent tells us how many times to multiply the base by itself. We will write...

In this video we will explore the reaction between acids and metal carbonates. Recall that an acid is a chemical that contains a special type of hydrogen that can be released into aqueous solution as a hydrogen ion, H+. Most metal...

👉 Learn how to solve problems with trapezoids. A trapezoid is a four-sided shape (quadrilateral) such that one pair of opposite sides are parallel. Some of the properties of trapezoids are: one pair of opposite sides are parallel, etc. A...

👉 Learn how to solve logarithmic equations. Logarithmic equations are equations with logarithms in them. To solve a logarithmic equation, we first isolate the logarithm part of the equation. After we have isolated the logarithm part of...

👉 Learn how to multiply with rational powers. To multiply two or more numbers/expressions with rational exponents, we apply the basic rules of exponents. If the two numbers/expressions are the same, we simply take one of the number and...

Master Simplifying an expression using the product rule of exponents

For this one we will need to understand the basics about Bronsted-Lowry acid-base reactions, and we also should be able to gauge the stability of various potential conjugate bases.

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!
