Answer:
B. A chemical formula that shows the relative number of each type of
atom in a molecule, using the smallest possible ratio
Explanation:
The empirical formula of a compound shows the relative number of each type of atom in a molecule and it uses the smallest possible ratio.
- It expresses the composition of the compound in the simplest whole number ratio of the atoms of the different elements that makes up the compound.
- To determine empirical formula of a compound , two pieces of information are needed;
- A. mass of each element in the compound
- B. Relative atomic mass of the constituent elements.
Answer:
no the answer is oxidation

Calcium and vitamin D are essential to building strong, dense bones when you’re young and to keeping them strong and healthy as you age. The information included here will help you learn all about calcium and vitamin D – the two most important nutrients for bone health.
What is Calcium and What Does it Do?
Cheese, milk, fish, almonds, and other bone-healthy foods
A calcium-rich diet (including dairy, nuts, leafy greens and fish) helps to build and protect your bones.
Calcium is a mineral that is necessary for life. In addition to building bones and keeping them healthy, calcium enables our blood to clot, our muscles to contract, and our heart to beat. About 99% of the calcium in our bodies is in our bones and teeth.
Every day, we lose calcium through our skin, nails, hair, sweat, urine and feces. Our bodies cannot produce its own calcium. That’s why it’s important to get enough calcium from the food we eat. When we don’t get the calcium our body needs, it is taken from our bones. This is fine once in a while, but if it happens too often, bones get weak and easier to break.
Too many Americans fall short of getting the amount of calcium they need every day and that can lead to bone loss, low bone density and even broken bones.
