Answer:
1. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.
2. a. The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
b. Acceleration is the rate of change of velocity.
3. It can be caused by friction.
Explanation:
The average kinetic energy of an ideal gas is calculated as
KE_avg = 3/2 kT
where T is the temperature in Kelvin and k=R/N_A; R is the universal gas constant and N_A is the number of moles.
Thus, upon substitution we get
KE_avg = 3/2(8.314/1)(100+273)
KE_avg = 3/2(8.314)(373)
KE_avg = 4651.683
The average kinetic energy of 1 mole of a gas at 100 degree Celsius is 4651.683 J.
The three main types of lipids are triglycerides, steroids and phospholipids
Answer:
Here's what I get.
Explanation:
According to Markovnikov's rule, the H will add to a terminal carbon, generating three resonance stabilized carbocations.
The Br⁻ ion will add to any of the three carbocations.
There are three possible products:
- 5-bromo-2,5-dimethylhexa-1,3-triene (1)
- 3-bromo-2,5-dimethylhexa-1,4-triene (<em>2</em>)
- 1-bromo-2,5-dimethylhexa-2,4-triene (3)
It’s organized by the atomic number which is the protons so the answer is A although they can be organized through groups and periods if valance electrons are included
