The answer is labels on lead-based paint

Lead is highly toxic metal and it is very strong poison. Lead poising takes place when lead builds up in the body. A little amount of lead can also cause various health problems.

Labels on lead-based paint do not prevent lead poisoning as much as advised to not using such product.

Instead of using lead-based paint, people could use safer products such as titanium-white based paint, which is proved to be less toxic.

Thus, option (A) is correct answer i.e. labels on lead-based paint is not among the current strategies which is used to prevent lead poisoning.

What is the ph of an aqueous solution with the hydronium ion concentration : [h3o+] = 3 x 10-5 m ?

BaLLatris [955]

The concentration of hydrogen can be shown as:

[H+ ] = 3 * 10-5 M

pH can be determined as:

pH = - log [H+ ]

= - log (3 * 10-5)

= 4.53

Thus the pH of solution is 4.53

A sample of water at 100°C is converted to steam after absorbing 820 kJ of heat. How grams of H2O are contained in the sample? A

Varvara68 [4.7K]

Since water is already at 100<span>°C all the energy is used to evaporate it.
Now we can calculate how many </span>mols of water are evaporated with 820kJ.
$N= \frac{820}{41} =20 mol$
We calculated that we got 20 mols of water evaporated. Now, all we have to do is find how many grams is a mol of water. Molar mass of water is <span>20.16 g/mol.
</span>The final answer is:
$m=20*20.16=403.2g$
