What are Isotopes?

What are Isotopes? Teacherflix 4 Views • 2 years ago

This chemistry video tutorial answers the question - what are isotopes? Isotopes are substances that are composed of the same element but consist of different mass numbers and number of neutrons. They share the same atomic number and therefore the same number of protons. This video contains plenty of examples and practice problems associated with isotopes and writing the atomic symbol for it.

Surface Tension of Water, Capillary Action, Cohesive and Adhesive Forces - Work & Potential Ener

Surface Tension of Water, Capillary Action, Cohesive and Adhesive Forces - Work & Potential Ener Teacherflix 4 Views • 2 years ago

This physics video tutorial provides a basic introduction into the surface tension of water. Surface tension prevents small amounts of water from flattening out across a surface. Rather, it causes water to minimize its surface area and as a result, water forms small beadlike droplets. This video also discusses the capillary action of water as it is draw up through small tubes known as capillaries. Surface tension can be calculated by divided the force per unit length required to increase the area of a fluid. The surface tension opposes the force and attempts to minimize the area. The work required to increase the area of a fluid by a force is the surface tension multiplied by the increase in area. This video discusses the difference in the capillary effects between water and mercury. Water rises above the surrounding fluid level in a thin glass tube where as mercury descends below that line. The adhesive forces in water is greater than the cohesive forces. In Mercury, the cohesive forces are greater than the adhesive forces. Adhesive forces exist between different molecules and atoms. Cohesive forces exist between the same type of molecules and atoms.

Oxidizing Agents and Reducing Agents

Oxidizing Agents and Reducing Agents Teacherflix 4 Views • 2 years ago

This video tutorial shows you how to identify the oxidizing and reducing agent in a redox reaction. The first step in determining which species is the oxidizing agent is to start by finding which reactant was reduced. Likewise, the molecule or element that is was oxidized is also the reducing agent. That's how you can determine it. However, you need to calculate the oxidation numbers or states for every element in the chemical equation. Oxidation involves a loss of electrons and occurs when the oxidation number increases. Reduction involves a gain of electrons and occurs when the oxidation state decreases.

Second Derivative Test

Second Derivative Test Teacherflix 4 Views • 2 years ago

This calculus video tutorial provides a basic introduction into the second derivative test. It explains how to use the second derivative test to identify the presence of a relative maximum or a relative minimum at a critical point. If the second derivative is positive at a critical number - a local minimum is present. If the second derivative is negative at a critical number - a local maximum is present. So to identify the relative extrema, find the first derivative, set it equal to zero and identify the critical numbers. Plug the critical numbers into the second derivative function to determine the concavity of the function to see if its concave up or concave down. If it's concave up - it's a relative maximum. If it's concave down, it's a relative minimum. You can confirm the results of the second derivative test using the first derivative test with a sign chart on a number line.

Finding All Zeros of a Polynomial Function Using The Rational Zero Theorem

Finding All Zeros of a Polynomial Function Using The Rational Zero Theorem Teacherflix 4 Views • 2 years ago

This precalculus video tutorial provides a basic introduction into the rational zero theorem. It explains how to find all the zeros of a polynomial function by using the rational zero theorem and by factoring polynomials. The rational zero theorem helps you to identify the first zero by listing all possible rational zeros and then evaluating the function to see if it's equal to zero at that particular value of x. This video also explains how to find all zeros of a polynomial function using synthetic division. You need to know how to factor trinomials and how to solve quadratic equations using the quadratic formula. This video contains plenty of examples and practice problems.
