Answer:

the molecules strike the walls of the container more often.

Explanation:

The pressure of a gas refers to the force per unit area exerted on the walls of container by gas molecules.

Since the average kinetic energy of gas molecules increases as the temperature of the gas increases, the molecules of the gas tend to strike the walls of the container more often as the temperature of the gas increases.

Hence, the pressure of a gas increases due to an increase in temperature because the gas molecules strike the walls of the container more often.

Explain why it is important that there be no gaps around the edges of the filter paper during a vacuum filtration
lesantik [10]

Vacuum filtration is more efficient and faster than filtration by the gravity method. But the set up of the vacuum filtration must be precise. Vacuum filtration is done under very reduced pressure hence there should be no gaps around the edges of the filter paper.   For a vacuum to be effective there must be no hole or gap in the equipment. Under vacuum conditions air is removed and the pressure is lowered. If there is gap then air would be continuously supplied and it would be difficult to remove air completely.

When you look out the window you can see constantly moving air.Air is cycled in order to reach equilibrium
aleksley [76]
False, although the air is moving in an equilibrium us normal humans can not see the air actually moving. So it is false.

An experiment was conducted and students observed that a solution had a hydroxide concentration of 7.0 x 10-2 .What is the pH? i
denis23 [38]

Answer:

The pH of the solution is basic

Explanation:

as one of the characteristics of the base is to increase the OH concentration in a solution so if the solution has low concentration of OH this means that the solution is basic

How many grams of hydrogen chloride can be produced from 1g of hydrogen and 55g of chlorine? What is the limiting reactant?
vova2212 [387]

Answer:

The limiting reactant is hydrogen, and the grams HCl produced is 36.175 g.

Explanation:

Balanced equation is 2 H + Cl2 = 2 HCl.

First thing, convert grams to moles via using molar mass.

Molar mass for hydrogen is 1.0079 g/mol. 1g x 1 mol / 1.0079 g = 0.99216 mol.

Molar mass for chlorine is 70.906 g/mol. 55g x 1 mol / 70.906 g = 0.7756748 mol.

Next, determine which is the limiting reactant - probably the fastest way to do it is just to take one of the reactants, say it's the limiting one, and calculate how much of the other reactant would be needed if that really was the limiting reactant, and then compare it to the actual moles of reactant available.

If hydrogen was the limiting reactant at 0.992 mol, you'd need .496 mol of Cl2 to complete the reaction.

If chloride was the limiting reactant at 0.776 mol, you'd need 1.55 mol of H to complete the reaction.

Comparing these numbers to the amounts we actually have available, the limiting reactant is hydrogen.

Once you've determined that, just plug in the amounts to the balanced equation to get the number of moles of HCL produced, which in this case, is just 0.992 mol.

Now, reverse the process that you took to get the moles of reactant, and you have the grams of product produced.

0.992 mol x 36.4609 g / 1 mol = 36.175 g.
