Answer:
Diphosphorus Pentaoxide
Explanation:
We have 2 atoms of Phosphorus and 5 atoms of Oxygen. It is a covalent bond.
2 is Di
5 is penta
Diphosphorus Pentaoxide
Answer:
vaporization. process by which thermal energy can overcome intermolecular forces and produce a state change from liquid to gas, the higher the temperature the greater the average energy of collection of molecules, ENDOTHERMIC
Explanation:
Hydrogen is composed of H atom and oxygen is composed of O atom. For water, it is composed by both H and O atom. If you burn hydrogen in oxygen, you can get water. And if you electrolysis water, you can get hydrogen and oxygen.
Answer:

Explanation:
To convert from moles to grams, we must find the molar mass.
1. Molar Mass
First, identify the elements in the compound. K₂CO₃ It has potassium, carbon, and oxygen. Find these elements and their masses on the Periodic Table.
- K: 39.098 g/mol
- C: 12.011 g/mol
- O: 15.999 g/mol
Note the subscript of 2 after K and 3 after O. We must multiply oxygen's molar mass by 2, then oxygen's by 3, and add carbon.
- 2(39.098 g/mol) + 3(15.999 g/mol) + 12.011 g/mol= 138.204 g/mol
2. Convert Moles to Grams
Use the molar mass as a fraction.

Multiply by the given number of moles: 6.2




There are <u>856.8648 grams</u> of potassium carbonate in 6.2 moles.
