The correct answer is realistic and reliable
Answer:
2M
Explanation:
M=mol/L
1. Find moles of CoCl2
mass of substance/molar mass = 130/129.833 = 1.001 mol
3. Substitute in molarity equation
M=(1.001/0.5)
M= around 2M
nuclear fusion
Stars produce their energy through nuclear fusion. For most stars, this process is dominated by a process called the "proton-proton chain," a sequence of events that transforms four hydrogen atoms into one helium atom.
The answer is a. 1.4

Answer: 0.84 g
Explanation:

Given: moles of iron = 0.015
Molar mass of iron = 56 g/mol

Thus 0.84 g of iron participated in the chemical reaction.
