Answer:
Explained below.
Explanation:
A tennis player with two sneakers wouldn't bond to any other tennis player because he is already stable and complete with the 2 and doesn't need another players assistance to make him stand well.
However, helium atom with two electrons wouldn't bond to any other atoms because it is stable. This stability arises from the fact that it has two protons and 2 electrons, of which the 2 electrons completely fill its valence shell/outer most shell to make it neutral.
Well it's an alkali metal if that's what you're asking<span />
The organic compounds that are divided into two types, simple and complex, are called carbohydrates.
Carbohydrates are diveded into twy types: simple and complex (starches, fiber, glycogen).
Simple carbohydrates are made of one (monosaccaharides) or two sugar units.
Complex carbohydrates are made up of many sugar units.
For example, glucose (C₆H₁₂O₆) is a simple carbohydrate.
Glucose is chemical compound composed of six carbon atoms, twelve hydrogen atoms and six oxygen atoms.
Starch is a polymeric carbohydrate consisting of a large number of glucose units bonded by glycosidic bond. Starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.

Answer:
54.1 % Ca, 43.2 % O, 2.7% H
Explanation:
Molecular formula for calcium hydroxide is Ca(OH)₂
As we don't have a mass of Ca(OH)₂ to find out the percentage composition, we consider that the question refers to 1 mol of compound.
1 mol of hydroxide weighs 74.08 g
1 mol of hydroxide has 1 mol of Ca, therefore 40.08 g are Ca
2 moles of O therefore 32g are O
2 moles of H therefore 2 g are H
Percentage composition is known as (Mass of element/Total mass) . 100
(40.08 / 74.08) . 100 = 54.1 %
(32 / 74.08) . 100 = 43.2 %
(2 / 74.08) . 100 = 2.7%
im a smart one
1 atom Mg, 2 atoms O and 2 atoms H.
1 + 2 + 2 = 5, so correct answer is C
