What best describes the collisions between ideal gas molecules?

1 answer:

Serggg [28]4 years ago

5 0

The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.

Given that 10.00mL of 0.1894M CH3COOH was titrated with 0.2006M NaOH in this experiment, calculate the volume, in mL, of NaOH re

sertanlavr [38]

Answer:

$V_{base}=9.442mL$

Explanation:

Hello!

In this case, when acetic acid is titrated with sodium hydroxide, the following chemical reaction is carried out:

$CH_3COOH+NaOH\rightarrow CH_3COONa+H_2O$

Whereas there is a 1:1 mole ratio between the acid and the base, which means that at the equivalence point we evidence:

$n_{acid}=n_{base}$

Which in terms of volumes and concentrations is written as:

$M_{acid}V_{acid}=M_{base}V_{base}$

Thus, solving for the required volume of base, we obtain:

$V_{base}=\frac{M_{acid}V_{acid}}{M_{base}}=\frac{0.1894M*10.00mL}{0.2006M}\\\\ V_{base}=9.442mL$

Best regards!

What is the enthalpy of the overall chemical reaction ch4(g)+4cl2(g)- ccl4(g)+4hcl(g)?

Brut [27]

Answer:

-205.7kj

Explanation:

Now adding reaction 2 and twice of reaction 3 and reverse of reaction 1, we get the enthalpy of the reaction.

The expression for enthalpy for the following reaction will be,

where,

n = number of moles

Now put all the given values in the above expression, we get:

Therefore, the enthalpy of the following reaction is, -205.7kj
