What volume of CH4(g), measured at 25oC and 745 Torr, must be burned in excess oxygen to release 1.00 x 106 kJ of heat to the su
anastassius [24]

Answer:

V=27992L=28.00m^3

Explanation:

Hello,

In this case, the combustion of methane is shown below:

CH_4+2O_2\rightarrow CO_2+2H_2O

And has a heat of combustion of −890.8 kJ/mol, for which the burnt moles are:

n_{CH_4}=\frac{-1.00x10^6kJ}{-890.8kJ/mol}= 1122.6molCH_4

Whereas is consider the total released heat to the surroundings (negative as it is exiting heat) and the aforementioned heat of combustion. Then, by using the ideal gas equation, we are able to compute the volume at 25 °C (298K) and 745 torr (0.98 atm) that must be measured:

PV=nRT\\\\V=\frac{nRT}{P}=\frac{1122.6mol*0.082\frac{atm*L}{mol*K}*298K}{0.98atm}\\\\V=27992L=28.00m^3

Best regards.

Concerning the 10.0 mL of 0.50 M NaCl 100 mL of soltion:Does the dilution change the concentration
disa [49]
The answer is affirmative because <span>dilutions give you a weaker Molarity 
Plase see this in the dilution formula that follows:

C1V1 = C2V2 
(0.50M) (10.00ml) = (C2) (100ml) 
C2 = 0.050 M 
10X's weaker
</span>Hope this helps a lot

2 H2 + 2 NO → N2 + 2 H2O the observed rate expression, under some conditions, is: rate = k[NO]2 Which of the following mechanism
guapka [62]

Explanation:

Rate law is defined as the rate of a reaction is directly proportional to the concentration of reactants at constant temperature.

               Rate \propto [\text{concentration of reactant}]^{n}

                                  = k [\text{concentration of reactant}]^{n}

where,     k = rate constant

                n = order of reaction

For the given reaction, 2H_{2} + 2NO \rightarrow N_{2} + 2H_{2}O

Hence, its rate will be as follows.

                   Rate = k[H_{2}][NO]

Also, it is known that slowest step in a chemical reaction is the rate determining step.

Hence, for the given rate law correct reaction is as follows.

Step 1 : H_{2} + NO \rightarrow N + H_{2}O (slow)

Balancing this equation it becomes H_{2} + 2NO \rightarrow N_{2}O + H_{2}O (slow)

Step 2: N_{2}O + H_{2} \rightarrow N_{2} + H_{2}O (fast)
