Answer:
894 deg K
Explanation:
The computation is shown below:
Given that
V1 denotes the initial volume of gas = 2.00 L
T1 denotes the initial temperature of gas = 25 + 273 = 298 K
V2 denotes the final volume of gas = 6.00 L
T2 = ?
Based on the above information
Here we assume that the pressure is remain constant,
So,
V1 ÷ T1 = V2 ÷ T2
T2 = T1 × V2 ÷ V1
= (298)(6) ÷ (2)
= 894 deg K
True, for example, hydrogen peroxide (liquid):
H₂O₂ + H₂O ⇄ H₃O⁺ + HO₂⁻
HO₂⁻ + H₂O ⇄ H₃O⁺ + O₂²⁻
(the resulting solution is weakly conducting)
Answer:
In the 1970s, Epel and other researchers showed that calcium is the essential factor that sparks development in eggs. As calcium levels rise, metabolic changes occur that cause the egg to divide and form into an embryo.
Explanation:
There is no need to do anything about the temperature, because sublimation does not involve any temperature change.
First, determine how many moles of CO2 there are. The mol. wt. of CO2 is 12 +2 x 16 = 44 g/mol.
So, 25.0 equals 25/44 = 0.568 moles
So the heat required is 0.568 mol x 32.3 KJ/mol = 18.3
