Which gas law states that the pressure of a gas decreases when volume is increased and the temperature is unchanged
Nesterboy [21]

Answer: Boyle's law

Explanation: It states that pressure of a gas is inversely proportional to the volume of a gas at constant temperature.

P∝\frac{1}{V}       at constant temperature

or If the pressure of gas is decreased, the volume increases if the temperature is unchanged and If the pressure of gas is increased, the volume decreases if the temperature is unchanged.

P_1V_1=P_2V_2

What is the effect of on the volume of a<br> gas?
Scrat [10]

Answer:According to Boyle's Law, the volume of a gas is inversely proportional to the pressure of a gas. Therefore, increasing the volume has the same effect as decreasing the pressure. If the volume in which a gas reaction takes place is DECREASED, the reaction will shift toward the side with fewer moles of GAS.

If the concentration of the stock (provided) Cu(NH3)42 was 0.041 M, what concentration will the Cu2 be in beaker?
kodGreya [7K]

Answer:

[Cu^{2+}]=0.041 M

Explanation:

Hello!

In this case, since the molarity of a solution is defined in terms of the moles of the solute and the volume of solution, given that the concentration of Cu(NH₃)₄²⁺ is 0.041 M, and there is only one copper atom per Cu(NH₃)₄²⁺ ion, we can compute the concentration of Cu²⁺ as shown below:

[Cu^{2+}]=0.041\frac{molCu(NH_3)_4^{2+}}{L}*\frac{1molCu^{2+}}{1molCu(NH_3)_4^{2+}} =0.041 \frac{molCu(NH_3)_4^{2+}}{L}

[Cu^{2+}]=0.041 M

Best regards!
