How many moles of phosphine (PH3) are produced for every 4.0 moles of hydrogen that react according to the chemical equation below? 3H2 + P2 → 2PH3

2.67 moles of Phosphine are produced

Explanation:

From the equation 3H2 + P2 → 2PH3

3 moles of hydrogen (H2) = 2 moles of Phosphine (PH3)

4 moles of hydrogen = X moles of PH3

Then, cross multiply

X moles of Phosphine = (4 x 2) / 3

= 8 / 3

= 2.67 moles

Thus, 4 moles of hydrogen produces 2.67 moles of Phosphine

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
