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

The cell membrane of a red blood cell will allow water, oxygen, carbon dioxide, and glucose to pass through. Since other substan
Mrrafil [7]

Answer:

The correct answer would be B. semi-permeable.

Plasma membrane of any cell including red blood cell is semi-permeable in nature as it is made up of lipid bilayer.

It permits the passage of certain substances across the membrane while it blocks other substances.

Gases, small uncharged or non-polar substances such as oxygen, carbon dioxide, et cetera can easily pass through the cell membrane of a cell.

Large or charged molecules such as proteins, sodium ions, potassium ions et cetera can not pass through the cell membrane. They require carrier proteins to pass through the membrane.
