What is the function of the phytoplankton in ocean ecosystems?--- A. producer B. consumer C. scavenger D. decomposer
Elodia [21]

The right answer is A. producer.

Phytoplankton are all cyanobacteria and microalgae (microscopic plants) present in surface waters and drifting with the currents. Unknown because invisible to the naked eye, phytoplankton is the lung of our planet. Thanks to photosynthesis, it produces more than half of the Earth's oxygen and consumes half of the carbon dioxide. Phytoplankton is essential for marine life because it is also at the base of the ocean food chain.

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
