How many particles are in 100.0 grams of gold

Chemistry
1 answer:
Tcecarenko [31]2 years ago
3 0
First, we need to convert the grams of gold into mole using the molar mass (molecular weight) of gold, and then into particles using avogadro's number (1 mol= 6.02 x 10^23)

molar mass of gold= 197 grams/ mole

100.0 grams (1 mole/ 197 grams) x (6.02 x 10^23 particles/ 1 mole) = 3.06 x 10^23

Write the complete and balanced chemical equation for this precipitation reaction. feso4(aq)+ba(oh)2(aq)→
Rzqust [24]
The chemical reaction that appears between the given compounds, ferrous sulfate and barium hydroxide, is a double replacement reaction. This is due to  the activity series of the metals being able to replace either of them in the compound. To balance the chemical reaction, ensure that the number of moles of each of the atoms in both sides of the equation are equal.

The answer to this item is,
          FeSO₄(aq) + Ba(OH)₂(aq) --> BaSO₄(s) + Fe(OH)₂ (aq)

As can be seen in the resulting equation, it does not need to be modified to balance it.

A cylinder is fitted with a moveable piston that can be raised and lowered. What would result in an increase in the pressure of
juin [17]

Answer:

decrease the volume of the cylinder.

Explanation:

In order to be able to solve this question we have to understand what Boyle's law is. According to Boyle's law; at constant temperature the pressure of a given mass of gas is inversely proportional to to its volume.

The Boyle's law shows us the relationship between the pressure and the volume. So, the Important thing to note hear is that if the volume in a container is decreased then the pressure will increase (and vice versa) due to the fact that as the volume decreases the particles in that container makes more collision which will make the pressure to increase.

Since, the piston is moveable it means that we can decrease and increase the volume in the cylinder. So, if the decrease the volume of the cylinder then we will have an increase in the pressure of the gas below the piston.
