A genetic pool is the absolute hereditary variety found inside a populace or an animal categories. A huge genetic stock has broad hereditary variety and is better ready to withstand the difficulties presented by ecological anxieties.
Analogous structures have a different evolutionary ancestries but they have the same function
while homologous structures are the opposite; they have similar ancestries and common traits but maybe not have the same function in an organism
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
