<u>Answer:</u> The mass of magnesium carbonate that will be dissolved in the reaction is 6.99 g.
<u>Explanation:</u>
We are given:
Amount of heat released = 1950 J = 1.950 kJ (Conversion factor: 1 kJ = 1000 J)
The chemical equation for the reaction of magnesium carbonate and hydrochloric acid follows:
By Stoichiometry of the reaction:
If 23.4 kJ of heat is released, then 1 mole of magnesium carbonate is dissolved
So, when 1.950 kJ of heat is released, then = 
of magnesium carbonate is dissolved
To calculate the mass of the substance by given number of moles, we use the equation:
Moles of magnesium carbonate = 0.083 moles
Molar mass of magnesium carbonate = 84.3 g/mol
Putting values in above equation, we get:
Hence, the mass of magnesium carbonate that will be dissolved in the reaction is 6.99 g.

Answer:
11.c) CO carbon two oxide which burns in limited supply of oxygen
Answer:
The strength of a bond depends on the amount of overlap between the two orbitals of the bonding atoms
Orbitals bond in the directions in which they protrude or point to obtain maximum overlap
Explanation:
The valence bond theory was proposed by Linus Pauling. Compounds are firmed by overlap of atomic orbitals to attain a favourable overlap integral. The better the overlap integral (extent of overlap) the better or stringer the covalent bond.
Orbitals overlap in directions which ensure a maximum overlap of atomic orbitals in the covalent bond.
