If you have 10 ml of hcl and 50ml of naoh, how many moles
ofwater are produced by the acid-base reaction?

0.3233 mol

Explanation:

Let's suppose that the acid (HCl) is concentrated (almost pure), thus, its density is 1.18 g/mL. The density of NaOH is 2.13 g/mL. The molar masses are: HCl = 36.5 g/mol, NaOH = 40 g/mol.

When an acid and a base react, they are neutralized, and salt and water are formed. The reaction of these two substances is:

HCl + NaOH → NaCl + H₂O

Thus, by the stoichiometry, 1 mol of HCl must react with 1 mol of NaOH to form 1 mol of water (H₂O). Let them found out which of the reactants is limiting. The mass is the volume multiplied by the density:

mHCl = 10 mL * 1.18 g/mL = 11.8 g

mNaOH = 50 mL* 2.13 g/mL = 106.5 g

The number of moles is the mass divided by the molar mass:

nHCl = 11.8/36.5 = 0.3233 mol

nNaOH = 106.5/40 = 2.6625 mol

So, HCl is the limiting reactant, thus it will react completely, and 0.3233 mol of water will be formed.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them  

the answer is d.) potassium
