You need to find the formula mass of NaCl first, which you find the amu of both sodium and chlorine on the periodic table and you add them both. Then you divide the 175.5g by the formula mass which I got 58 g to get 3.026 moles of NaCl. 4 sig figs because of the 175.5. I recommend doing it on your own to make sure you get the right answer. You divide the 175.5g of NaCl by the formula mass.
The balanced chemical equation between nitric acid and calcium hydroxide is:
2HNO3 (aq) + Ca(OH)2 (aq) ---> Ca(NO3)2 (aq) + 2H2O (l)
Calcium oxide has the chemical formula Ca(OH)2, while nitric acid has the formula HNO3. Salt (an ionic substance created by the reaction of an acid and a base) and water are the byproducts of the reaction between an acid and a base.
Now, to balance the equation, we have to make sure there are the same number of atoms (or ions) on both sides of the equation. Also, we must list the state of each compound in the equation.
HNO3 (aq) + Ca(OH)2 (aq) ---> Ca(NO3)2 (aq) + H2O (l)
We must balance the equation because the number of atoms on each side is not equal. To the right of the chemical formulas, put the balancing numbers.
The balanced chemical equation between nitric acid and calcium hydroxide has the equal amount of atoms on both sides as a result.
2HNO3 (aq) + Ca(OH)2 (aq) ---> Ca(NO3)2 (aq) + 2H2O (l)

White gold is yellow gold that has had other alloys added to it to make it appear white. New polished white gold has a bright white metal color. Depending of the type of alloys used in the fabrication of white gold, white gold jewelry tends to have a faint yellowish tint with wear.
Answer:
They also showed the effects of pressure on volume if temperature stayed the same
Explanation:
They also showed the effects of pressure on volume if temperature stayed the same is the experiment that will provide an evidence for Boyle's law.
Boyle's law states that "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
- The law is an affirmation of what happens when there is a dynamics between pressure and volume if temperature is made constant.
- So the experiment designed to investigate this proves and shows Boyle's law.
