Answer:
According to avogadro's law, 1 mole of every substance contains avogadro's number 
of particles and weighs equal to its molecular mass.
To calculate the moles, we use the equation:
a. moles in 14.08 g of 
= 
molecules in 14.08 g of = 
b. moles in 17.75 g of NaCl = 
molecules in 17.75 g of 
= 
formula units 17.75 g of =
c. moles in 20.06 g of 
= 
formula units in 20.06 g of = 
Answer:
2HCl is the product of this reaction 2 is added in order to balance the reaction
Answer: C. The number of atoms of each element is the same on each side of the equation.
Explanation:
The Law of Conservation of Matter shows that it is not possible for matter to either be created nor for it to be destroyed so the number of atoms of each element on the reactant side of the equation must equal the number of atoms in each element on the product side of the equation.
This is why the following equation is incomplete:
H₂ + O₂ ⇒ H₂O
The oxygen atoms are not the same on either side.
Equation will therefor have to be balanced which will make it:
2H₂ + O₂ ⇒ 2H₂O
Notice now that atoms are the same on both sides.
Answer:
33/16 S
Explanation:
In beta decay, the atomic number of the daughter nucleus increases by one unit while the mass of the daughter nucleus remains the same as that of the parent nucleus.
Hence, if we know that a beta decay has occurred, then the parent nucleus must have the same mass as its daughter nucleus but have an atomic number that is less than that of the daughter nucleus by only one unit, hence the answer above.
