The answer is : B. age of material

thermal Energy is an energy that come from heat, which caused by the movement of the particles in that substance. The faster it moves, the more energy it produced, which is affected by the change of temperature, its composition, and its size

Use logarithmic properties to solve the following equation log3 5x+ log3 7= 4 leave your answer in fraction form please

Salsk061 [2.6K]

Explanation:

Adding logs of same base is equivalent to multiplying the arguments. You get:

$log_{3}(35x) = 4$

Use the definition of the log to turn this into an exponential function:

${3}^{4} = 35x$

$81 = 35x$

$x = \frac{81}{35}$

A container of N2O3(g) has a pressure of 0.265 atm. When the absolute temperature of the N2O3(g) is tripled, the gas completely

Rzqust [24]

Answer:

1.59 atm

Explanation:

The reaction is:

$N_{2}O_{3}(g) - - -> NO_{2}(g)+NO(g)$

The dalton's law tell us that the total pressure of a mixture of gases is the sum of the partial pressure of every gas.

So after the reaction the total pressure is:

$P_{total}=P_{NO_{2}}+P_{NO}$

we don't include $N_{2}O_{3}$ because it decomposed completely.

Assuming ideal gases

PV=nRT

P= pressure, V= volume of the container, n= mol of gas, R=constant of gases and T=temperature.

so moles of $N_{2}O_{3}$ is:

$n_{N_{2}O_{3}}=\frac{P_{1}V}{RT_{1}}$

from the reaction stoichiometry (1:1) we have that after the reaction the number of moles of each product is the same number of moles of $N_{2}O_{3}$ .

$n_{NO_{2}}=\frac{P_{1}V}{RT_{1}}$
