You first need to write the balanced chemical reaction for what is going on.
Ca(OH)₂+2HCl→2H₂O+CaCl₂
After you make the balanced chemical reaction, First you find the moles of HCl used. To do this multiply 0.0375L by 0.124M to get 0.00465mol HCl. Then you multiply 0.00465mol HCl by (1mol Ca(OH)₂)/(2mol HCl) to get 0.002325mol Ca(OH)₂. Finally to find concentration of Ca(OH)₂ used you divide 0.002325mol by 0.020L to get 0.116M Ca(OH)₂.
Therefore the concentration of the unknown solution of Ca(OH)₂ was 0.116M.
I hope this helps. Let me know if anything is unclear.
<u>Answer:</u> The chemical formula of Iron (III) sulfate is 
<u>Explanation:</u>
Iron is the 26th element of periodic table having electronic configuration of ![[Ar]3d^64s^2](https://tex.z-dn.net/?f=%5BAr%5D3d%5E64s%5E2)
.
To form 
ion, this element will loose 3 electrons.
Sulfate ion is a polyatomic ion having chemical formula of 
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the chemical formula for Iron (III) sulfate is

It could also treat niacin deficiency along with high triglyceride and cholesterol levels. Additionally, it can lessen the chance of a heart attack but also slow artery narrowing.
Niacin, sometimes referred to as nicotinic acid, would be a naturally occurring vitamin 
found in the diet. It can raise blood lipid (fat) levels, including triglycerides and cholesterol, when used as medicine. In order to exert its effects, nicotinic acid causes the liver to produce less "bad" cholesterol and triglycerides.
Therefore, The term identifies the characteristic tingling sensations and reddening of the skin after ingesting a pharmacologic dose of nicotinic acid will be<u> naicin flush.</u>

The pressures given are the partical pressures of the two gases.
The law of Dalton or of the partial pressures states that the total pressure of a mixture of gases is equal to the sum of the pressures of all the gases.
So, in this case:
Total pressure = pressure of nitrogen + pressure of carbon dioxyde.
Of course both terms must be in the same units.
i have found that the pressures for this problem are:
Pressure of nitrogen = 984 torr
Pressure of carbon dioxyde = 345 torr
Total pressure = 984 torr + 345 torr = 1329 torr.
Now convert to atm: 1 atm = 760 torr
=> 1329 torr * 1 atm / 760 torr = 1.74868 atm ≈ 1.75 atm
Answer: 1.75 atm
Answer:1)1.99 M
Explanation:
Molarity is given as = moles solute/Liter solution
The solute which is LiOH is already given in moles as 1.495 moles
Given that solution is 750 mL, we convert to liters.
Liters of the solution= mL of the solution x (1 L/1000 mL)
750 mL x (1 L/1000 mL)
0.75 L
Molarity = moles solute/Liter solution
Molarity = 1.495 moles of LiOH/0.75 L of solution
Molarity = 1.99M
The molarity of this solution is 1.99M (moles per liter).
