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

morpeh [17]

Answer:

It fuses with and becomes part of the plasma membrane.

Explanation:

Exocytosis -

Exocytosis is the process of expelling out the substances from the cell . It also helps in the cell transport and cell signalling process .

In this process a large amount of molecule are released and making it a form of the bulk transport .

In this process , the secretory vesicles are then carried to membrane of the cell and then their contents are secreted into the extracellular environment .
