Answer:

New net worth to three significant figures = $80.2 billion

Dollars are given to charity = $100,250,000

Explanation:

Net worth = $77.0 billion

stock Gains = $3.20 billion

New net worth = $77.0 billion + $3.20 billion = $80.20 billion

New net worth to three significant figures = $80.2 billion

One-eighth of a percent = (1/8 x 1) / 100 = 0.00125

Dollars are given to charity = 0.00125 X $80.2 billion = $100,250,000

Or

$80,200,000,000/100 = $802,000,000

state the behaviour of equilibrium , of ammonia is removed from the reaction mixture . Explain your answer
OLEGan [10]

Equilibrium

N₂(g) + 3H₂(g) ⇔ 2NH₃(g)

If the concentration of the reactants is added, the system will reduce the concentration of the reactants by shifting towards the products and vice versa if the concentration of the reactants is decreased the system will shift towards the reactants.

ammonia is removed from the reaction mixture ⇒ it means the ammonia is reduced then the equilibrium shifts to the right
