Collisions of helium atoms with the walls of a closed container cause
iogann1982 [59]
1) Option b: gas pressure.

This is sustainted by the kinetic molecular theory of the gases.

2) Option c: raising the temperature of the gas will increase the pressure if the volumen of the gas and the number of particles are constant.

PV = nRT

If V and n are constant, P is proportional to T, then if T increase P will increase too.

A gas made up of homonuclear diatomic molecules escapes through a pinhole 0.378 times as fast as He gas. Write the chemical form
yulyashka [42]

For a gas made up of homonuclear diatomic molecules escapes through a pinhole 0.378 times as fast as He gas, the chemical formula of the gas  is mathematically given as

N2(nitrogen gas)

<h3>What is the chemical formula of the gas.?</h3>

Generally, the equation for the rate to molar relationship  is mathematically given as

\frac{r1}{r2}=\frac{mm2}{mm1}

Thereofore

\frac{r}{r2}=0.378

Hence

0.378=\sqrt{\frac{4.00268}{Mx2}}

Mx2=28.013g/mol

In conclusion,The name of gas with a molar mass of 28.013g/mol is N2

Therefore, the chemical formula of the gas. is N2

If a 91.3 g piece of aluminum has a density of 2.7 g/cm3, what is its volume in cubic centimeters?
Alex_Xolod [135]

Answer:

<h2>The answer is 34 cm³</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass of aluminum = 91.8 g

density = 2.7 g/cm³

It's volume is

volume =  \frac{91.8}{2.7}  \\

We have the final answer as

<h3>34 cm³</h3>

Hope this helps you
