11. You have 700 grams of AgO. How many moles are present?

solniwko [45]

<h2>Answer:</h2>

5.65moles

<h2>Explanations:</h2>

The formula for calculating the number of moles the compound contain is given as:

$moles=\frac{Mass}{Molar\text{ mass}}$

Given the following parameters

Mass of Ag = 700grams

Determine the molar mass of AgO

Molar mass = 107.87 + 16

Molar mass = 123.87g/mol

Determine the moles of AgO

$\begin{gathered} moles=\frac{700}{123.87} \\ moles\text{ of AgO}=5.65moles \end{gathered}$

Hence the moles of AgO present is 5.65moles

Hydrogen gas is collected over water in an inverted buret. If the atmospheric pressure is 745 mm Hg, the vapor pressure of water

Varvara68 [4.7K]

Answer:

$P_{H_2}=727mmHg$

Explanation:

Hello there!

In this case, according to the given data, it is possible to infer that the gas mixture lies on the 15.0 cm-high column of water, so that the total pressure or atmospheric pressure is given by:

$P_{atm}=P_{water}+P_{H_2}$

Thus, since the atmospheric pressure is 745 mmHg and the vapor pressure of water is 18 mmHg, the pressure of hydrogen turns out to be:

$P_{H_2}=P_{atm}-P_{water}\\\\P_{H_2}=745mmHg-18mmHg\\\\P_{H_2}=727mmHg$

Best regards!

How does temperature, pressure and surface area affect the dissolving process

larisa [96]

If I am correct, yes. As I was told in chemistry, the surface area affects the dissolving of the "sugar". If you put regular Surat in a hot cup of coffee, it will dissolve at a quick pace, but what if you put the same amount of sugar in the same amour of coffee, but the sugar was fine powder? It would dissolve even faster since it has more surface area. So temperature does affect the dissolving. Hope this helps!

Could a mixture be made up of only elements and no compounds. explain

lbvjy [14]

Yes, because a mixture is 2 or more substances that are mixed together (not chemically). A mixture could be two different elements physically combined in a set ratio.
