Since the coefficient of NH3 is 2, 100.4 kJ of heat is released when 2 moles of NH3 are formed. So, when one mole of NH3 is formed, half of the heat would be produced or 50.2 kJ.

An inventor claims to have developed a new perfume that lasts a long time because it doesn't evaporate. Comment on this claim.

zaharov [31]

Answer:

Explanation:

Perfume needs to evaporate in order to smell. If this perfume didn't evaporate, it would stay as a liquid and never smell.

It wouldn't be D, as no toxic perfumes is sold.

It's not A because perfume doesn't have to be pressurized in order to not evaporate.

It's not B, as it is a hasty conclusion to the claim. Plus, if the perfume did have an odor, even while not evaporating, the sales would be low as the product is that good.

Someone help me with this please, it’s overdue:(

Zolol [24]

Answer:

See explanation.

Explanation:

Hello there!

3. In this case, according to the given question, it turns out possible for us to say that any chemical formula, for an ionic compound, has the cation (positive) on the left and the anion (negative) on the right; thus, since Mg is a metal, which tends to lose electrons and become positively charged whereas the Cl is a nonmetal, which tends to gain electrons and become negatively charged, we have the following:

$Mg^{2+}Cl^-\\\\Mg^{2+}Cl^-_2\\\\MgCl_2$

4. In this case, since lithium is a metal, as well as magnesium, it is not possible for them to switch around their charges as they will not be bonded because they will be repelled rather than attracted because of their equal positive charges.

Regards!
