Population growth how is population growth naturally regulated answer key

1 answer:

6 0

Population growth comes from a balance between food supply and predators. When pray increases food supply decreases, since they are eating them alot. As a result some of the prey dies off since there isn't enough food for them. Then the food supply increases but then suddenly dies off after pray comes backs and eats them. As a result the cycle continues

What will be the theoretcal yield of tungsten(s) ,W, if 45.0 g of WO3 combines as completely as possible with 1.50 g of H2? WO3(

7nadin3 [17]

Answer:

Theoretical yield of tungsten produced = 35.6836915592 ≈ 35. 68 g

Explanation:

The chemical equation can be expressed as follows;

WO3 (s) + 3H2(g) → W(s) + 3 H20(g)

Note that the equation is already balanced.

Molecular Mass of WO3= 183.84 + 15.999 × 3 = 183.84 + 47.997 = 231.837 g

From the equation 1 mole of WO3 reacts with 3 mole of hydrogen molecule.

Molecular mass of tungsten(W) = 183.84 g

1 mole of tungsten was produced from the chemical equation.

WO3 (s) + 3H2(g) → W(s) + 3 H20(g)

From the equation,

231. 837 g of WO3 produces 183.84 g of tungsten

45.0 g of WO3 will produce ?

grams of tungsten produced = 183.84 × 45 /231.837

grams of tungsten produced = 8272.8 /231.837

Theoretical yield of tungsten produced = 35.6836915592 ≈ 35. 68 g
