Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. Puffer fish contain a powerful toxin that can kill

an adult a few hours after ingestion. Sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. Recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. This recent scientific discovery would fall under which area of chemistry?

Calculate the volume of 0.100 m hcl required to neutralize 1.00 g of ba(oh)2 (molar mass = 171.3 g/mol).
dedylja [7]

The balanced chemical equation between HCl and Ba(OH)_{2} is:

2HCl (aq) + Ba(OH)_{2}(aq) -->BaCl_{2}(aq) + 2 H_{2}O(l)

Moles of Ba(OH)_{2} = 1.00 g Ba(OH)_{2} * \frac{1 mol Ba(OH)_{2}}{171.3 g Ba(OH)_{2}} = 0.00584 mol Ba(OH)_{2}

Moles of HCl required to neutralize Ba(OH)_{2}:

0.00584 mol Ba(OH)_{2} * \frac{ 2 mol HCl}{1 mol Ba(OH)_{2}} =   0.01168 mol HCl

Calculating the volume of HCl from moles and molarity:

0.01168 mol HCl * \frac{1 L}{0.100 mol} * \frac{1000 mL}{1 L} = 116.8 mL

If a substance can be physically separated into its components, is it a pure substance or a mixture?
Marizza181 [45]
I think its pure substance since you are breaking into its components. For example if you were to break the components of salt apart (NaCl) You will be left with sodium and chloride which are the pure elements of salt. Therefore i believe pure is the best answer.
