<span>Number of moles of Fe(CO)5 = mass/molar mass = (6.0 g) / (195.8955 g/mol) = 0.03 mol Number of moles of PF3 = (4.0 g)/ (87.97 g/mol) = 0.0455 mol Number of moles of H2 = (4.0 g) / (2.016 g/mol) = 1.984 mol From the balanced equation 1 mol of Fe(CO)5 reacts with 2 mol of PF3 and 1 mol of H2 then 0.03 mol of Fe(CO)5 will need 0.03 (2/1) = 0.06 mol of PF3 and 0.03 mol of H2 Since we have less PF3 ( 0.0455 mol instead of 0.06 mol), that is the limiting agent</span>

A 12.0g sample of a substance requires 50.9 J to raise its temperature by 6.00 c. What is it’s specific heat
horsena [70]

\qquad\qquad\huge\underline{{\sf Answer}}

Let's find the specific heat of sample using given formula :

\qquad \tt \dashrightarrow \:Q = m \: s \triangle T

where,

  • Q = heat transfer

  • m = mass

  • S = specific heat

  • \tt \triangle T = change in temperature

\qquad \tt \dashrightarrow \:50.9 = 12 \times \: s  \times 6

\qquad \tt \dashrightarrow \:s =  \dfrac{50.9}{72}

\qquad \tt \dashrightarrow \:s = 0.707  \:

Therefore, specific heat of that substance is 0.707 J/g°C

sladkih [1.3K]
The correct answer from the choices given is the last option. The can from the <span> car will lose the carbon more quickly because there are fewer solute–solvent collisions. The can in the car has a lower temperature than the one in the refrigerator. At low temperature, the solubility of carbon dioxide in the liquid decrease therefore particles would tend to be in the vapor phase and escape from the liquid.</span>

13. When a train car traveling at 4 m/s collides with a stationary train car, what happens to the momentum of the first train ca
Solnce55 [7]

Answer:

Momentum of first train car will reduce

Explanation:

When the moving care collides with the stationary car, it will increase the momentum of the stationary car. However, its own momentum will reduce.

It is so because the speed of the first train car will reduce after collision due to loss of energy in the collision while the stationary car may gain some momentum due to rise in velocity from zero (velocity at stationary position).
