Answer:The nucleus contains two types of subatomic particles,
protons and neutrons.
Explanation:The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus.
The mole ratio between sodium bicarbonate and that of acetic acid is 1:1
<h3>What is mole ratio?</h3>
A mole ratio can be defined as that ratio in whole numbers between the amounts in moles of any two compounds involved in a balanced chemical reaction.
- The mole ratio of each individual element is found by dividing the number of moles of each by the smallest number of moles.
In conclusion, the mole ratio between sodium bicarbonate and that of acetic acid is 1:1

Answer:regular variation in magnitude or position around a central point. Or movement back and forth at a regular speed
Explanation:
Answer:
Here are the most common formulas associated with a sphere:
The volume (V) of a sphere is the amount of 'stuff' that could fit inside the sphere. Usually, when discussing volume, it is in terms of a liquid or gas. An example would be, 'What is the volume of air that can fit inside a basketball?' The formula for volume is:
V = (4/3?r^3
Surface area is just what its name implies: it's the area of the surface of an object. So, if you could cut open the basketball from the previous example and lay its surface out flat, you could see the surface area? This is useful for determining how much material would be needed to cover the sphere in question. The formula for surface area is:
SA = 4?r^2
Examples
Using our formulas, let's take a look at some example problems using spheres:
1.) What is the volume of a ball with a radius of 6 inches? (We'll use 3.14 for pi and round our answer to the nearest .10.)

(+1 × 2) + (2 × x) + (-2 × 3) = 0
2+2x-6 = 0
2x-4 = 0
2x = 4
x = 4/2
x = +2....
