Answer:
See explanation
Explanation:
Potassium is a metal. Remember that metals are electropositive in nature. This implies that they give out electrons when they undergo ionic bonding with nonmetals.
Chlorine is a nonmetal. So the bond between chlorine and potassium is ionic. Potassium gives out one electron to chlorine and the both ions now attain a stable octet.
The electronic configuration of potassium is [Ar]4s1. After giving out an electron to chlorine in an ionic bond, its electronic configuration is now [Ar].

Answer:
The molar mass of:
Helium = 4.00 g/mol
Potassium = 39.0983 g/mol
Manganese = 54.94 g/mol.
Boron = 10.81 g / mol
Explanation:
Helium = 4.00 g/mol
Potassium = 39.0983 g/mol
Manganese = 54.94 g/mol.
Boron = 10.81 g / mol
Answer:
Mass of the water = 0.1kg is 100g
Explanation:
Mathematically;
Quantity of heat = mass of water * specific heat capacity * temperature change
From the question, we identify the following;
Quantity of heat = 6.3 KJ
1 KJ = 1000 J, so 6.3 KJ = 6.3 * 1000 = 6300 J
Mass of water = ?
Specific heat capacity = 4200
Temperature change is the difference between the final and initial temperature. = 75-60 = 15
6300 = m * 15 * 4200
63 = m * 15 * 42
63 = 630 m
m = 63/630
m = 0.1 kg
The formula is NaCi, containing equal amounts of sodium and chloride
