Given that Kp [NOTE: Kp!!!!] = 1.39 at 400 ºC for the reaction, P4(g) <=> 2 P2(g), which answer best describes the reactio

Igoryamba

Answer:

The reaction will proceed to the left to attain equilibrium.

Explanation:

The question is missing but I guess it must be about how the reaction will proceed to attain equilibrium.

First, we have to calculate the partial pressures using the ideal gas equation.

$pP_{4}=\frac{2.50mol\times (0.08206atm.L/mol.K)\times 673K}{25.0L} =5.52atm$

$pP_{2}=\frac{1.50mol\times (0.08206atm.L/mol.K)\times 673K}{25.0L}=3.31atm$

Now, we have to calculate the reaction quotient (Qp).

$Qp=\frac{pP_{2}^{2}}{pP_{4}} =\frac{3.31^{2} }{5.52} =1.98$

Since Qp > Kp, the reaction will proceed to the left to attain equilibrium.

Pick the correct products for the following reaction acid + metal reaction: 2 HNO3 + Co -->

MrMuchimi

Answer:

2. Co(NO3)2 + H2

Explanation:

Hello,

In this case, we are evidencing a simple displacement reaction wherein the cobalt is able displace the hydrogen to produce cobalt (II) nitrate and gaseous hydrogen as a result of cobalt's higher activity:

$2 HNO_3 + Co\rightarrow Co(NO_3)_2+H_2$

Therefore, answer is 2. Co(NO3)2 + H2.

Best regards.

What is the empirical formula of a compound containing 5.03 grams carbon, 0.42 grams hydrogen, and 44.5 grams chlorine?

PtichkaEL [24]

Answer:

The right choice is CHCl₃

Explanation:

To find the empirical formula firstly, change the mass to moles.

For Carbon :

no. of moles = (mass / molar mass) = (5.03 g / 12 g/mol )= 0.42 mol

For Hydrogen :

no. of moles = (mass / molar mass) = (0.42 g / 1 g/mol )= 0.42 mol

For Chlorine :

no. of moles = (mass / molar mass) = (44.5 g / 35.5 g/mol )= 1.25 mol

The ratio for Carbon and Hydrogen is 1 : 1

0.42 mol / 042 mol =1.00

Then find a ratio between the moles.

The ratio of Chlorine to both Carbon and Hydrogen is 3:1

1.25 mol / 0.42 mol = 2.98 ≅ 3

So the ratio is 1 C : 1 H : 3 Cl.

So, the right choice is CHCl₃

Carbon usually forms four bonds one to Hydrogen and 3 to Chlorine atoms.

Chlorine usually forms one bond to Carbon atom.

Hydrogen usually forms one bond Carbon atom.
