Which of the metals below will dissolve in hydrochloric acid, HCl? gold, Au copper, Cu silver, Ag magnesium, Mg

Lera25 [3.4K]

Magnesium (Mg)

The reason for this is the reactivity of the listed metals. Gold and silver are extremely unreactive metals. It is because of this unreactive nature that they remain in good condition for long periods of time, and are preferred in jewelry. Copper, although more reactive than gold and silver, is still not reactive enough to react with HCl.
The only metal that will react is magnesium.

How many grams of NaOH are produced with the reaction of 5.00 moles of water? *

Andre45 [30]

Answer:

200 grams of NaOH are produced with the reaction of 5.00 moles of water

Explanation:

First of all you apply a rule of three to know the amount of moles of NaOH as follows: if 2 moles of water produce 2 moles of NaOH, 5 moles of water how many moles would they produce?

$moles of NaOH=\frac{5 moles of water*2 moles of NaOH}{2 moles of water}$

moles of NaOH= 5

Being:

Na: 23 g/mole
O: 16 g/mole
H: 1 g/mole

the molar mass of NaOH is: 23 g/mole + 16 g/mole + 1 g/mole= 40 g/mole

Then a rule of three applies as follows: if in 1 mole there are 40 g of NaOH, in 5 moles how much mass is there?

$mass=\frac{5 moles*40g}{1 mole}$

mass= 200 g

200 grams of NaOH are produced with the reaction of 5.00 moles of water

Use collision theory to describe the relationship between temperature and volume of a gas.

zzz [600]

Answer:

Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant.
