The liters in 3.25 g of ammonia 4.28 L
<u><em>calculation</em></u>
Step 1: find moles of ammonia
moles = mass÷ molar mass
From periodic table the molar mass of ammonia (NH₃) = 14 +(1×3 ) = 17 g/mol
3.25 g÷ 17 g/mol = 0.191 moles
Step 2: find the number of liters of ammonia
that is at STP 1 moles = 22.4 L
0.191 moles = ? L
<em>by cross multiplication</em>
={( 0.191 moles ×22.4 L) / 1 mole} = 4.28 L

I think the correct answer is B. An example of gene therapy is when a defective gene is replaced with a normal gene.
The given blank can be filled with less and even cooler.
A long duration of decline in the temperature of the surface of the Earth and atmosphere, leading to the expansion or existence of the polar and continental ice sheets and alpine glaciers is known as an ice age.
During an ice age, there are many periods of glaciation that are periods when ice sheets and glaciers cover the majority of the Earth's surface.
The ice reflects more sunlight back into outer space than does the vegetated or bare ground. As the glaciers and ice sheets are more reflective, they captivate less sunlight and thus discharge less heat. This makes the climate of the Earth to become even cooler during the times of glaciation.
