Answer:
a. 10.0 g
Explanation:
The molar mass of NaOH is 39.997 grams which was calculated by adding the molar mass of Sodium, Oxygen, and Hydrogen
. But before we do anything with this number we must first convert
molecules to moles. We can do this by dividing by Avogadro's number or
(
moles). We then convert moles to grams by multiplying by the molar mass of NaOH, (
grams). This is almost exactly 10 and the margin of error is likely due to the original numbers not being precise enough.
Answer:
A synthesis reaction is <em>a reaction that occurs when two or more reactants combine into one product.</em>
Explanation:
A reaction that occurs when two or more reactants combine into one product is called a synthesis reaction.
A reaction that occurs when one element within a compound is exchanged with another element is called a single replacement reaction.
A reaction that occurs when a substance combines with molecular oxygen, releasing light and energy is called combustion.
A reaction that occurs when a single substance breaks apart and forms two or more new substances is called decomposition.
A. cesium. bacause as the elements go down a group of the atoms, the sizes of the atom will increase . we know that tge tendency to lose an electron is based on the sizes of the atoms of group 1.
