Answer:
You must change the size of each ingredient by the size of the product. Let's say my recipe calls for 1 bag of flower and 2 eggs. I want to double the amount of product that I make, so I must multiply each of my ingredients by 2. I would now use 2 bags of flower and 4 eggs.
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.

I guess the answer is D point
Answer:
Yes A redox reaction can be a combination reaction.
Two elements are mixed in a combination reaction to produce a single product.
Explanation:
Example: water formula
2H2 + O2 → 2H2O
Oxygen is reduced in this reaction when electrons are transferred from hydrogen to oxygen and hydrogen is also oxidized since oxygen from hydrogen accepts electrons. Oxygen is the oxidizing agent and hydrogen is the reducing agent.
2H2 + O2 → 2H2O
Answer:Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.
