Answer:
Explanation:
Data:
Mass of NaCl = 4.6 g
Mass of water = 250 g
Calculations:
Mass of solution = mass of NaCl + mass of water = 4.6 g + 250 g = 254.6 g.
The answer is D. To put it simply, all atom wished to become stable. The only way for that is to obtain an octet structure where the outermost shell would have 8 electrons, thus being full.
In this question, the sulfur atom has atomic number 16 and atomic mass 33. The Atomic number represents the number of the proton inside the atoms and atomic mass represent the mass of the atoms. Since electron mass to small, the atomic mass can be interpreted as the sum of neutron and proton. Then, the number of the neutron would be:
mass= neutron + proton
33= neutron+16
neutron = 17
Answer:
H2 P4 O1. Explanation: In order to calculate the Empirical formula , we will assume that we have started with 10 g of the compound.
Explanation:
It’s chlorine (Cl) having the atomic number 17
