<span>Answer:
Mass % KCL:
Add the grams of both compounds (31.0 g KCL + 225 g water) to find total mass and then divide the grams of KCL over the total mass, then multiply by 100: ( 31.0 g KCL / 31.0 g + 225 G) * 100%
Mole fraction KCL
Calculate the moles of KCL and water and add them to find the total moles (Moles of KCL + moles of water). Then, divide the number of KCL moles over the total moles.
moles of KCL/ moles kcl + moles water= mole fraction of KCL</span>
Nitrogen atomic# 7 7protons, 7electrons, 7 neutrons
Oxygen atomic# 8 8protons, 8electrons, 8neutrons
Phosphorous atomic# 15 15protons, 15 electrons, 15 neutrons
Sulfur atomic#16 16protons, 16electrons, 16 neutrons
The only true answer is A.
products are on the right side of the reaction
products and reactants don't necessarily have same physical or chemical properties
It is the reactants that <span>are the atoms, molecules, or compounds that participate in the reaction.</span>
