Answer:
74 g/mol
Explanation:
Using a periodic table, we can determine the molar mass by adding together 1 Ca, 2 O, and 2 H. This turns out to be approximately (40+32+2) = 74 g/mol
Assuming the surface on which the box moves is frictionless, the rate at which the box accelerate is equal to 0.5
.
<u>Given the following data:</u>
- Mass of box = 50 kilogram
To determine the rate at which the box accelerate, assuming the surface on which the box moves is frictionless:
Mathematically, Newton's Second Law of Motion is given by the formula;

Making acceleration the subject of formula, we have:

Substituting the given parameters into the formula, we have;

Acceleration = 0.5

Answer:
none of the above
Explanation:
because all of them are unstable
A and D make the most sence
Answer:
When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction. When you increase the pressure, the molecules have less space in which they can move. That greater density of molecules increases the number of collisions.
