If 1.0 mole of CH4 and 2.0 moles of Cl2 are used in the reaction CH4 + 4Cl2 => CCl4 + 4HCl then which of these statements is
nikklg [1K]

Answer:

B,C,D

Explanation:

The yield of CCl4 depends on the amount of CH4 in a 1:1 ratio. The amount of Cl2 is twice that of CH4 hence some must be left over. To ensure that all the Cl2 is used up, more CH4 must added to the system.

Q 1. Element M is a metal that forms compounds of the type MX2, MX3, and MX4, where X is a Chlorine (Cl).
SOVA2 [1]

Answer:

See explanation

Explanation:

The ionic radius of metal M decreases as the charge on the metal M increases. The ionic radius is generally defined as the distance between the nucleus and the outermost electron of the ion. Hence, ionic radius becomes much lesser as the magnitude of the positive charge increases.

It is obvious  from the various formulae of metal chlorides in the question that the metal forms cations M^2+, M^3+ and M^4+ respectively. The order of decreasing ionic radius of the compounds is;

MX2 > MX3 > MX4

5. How many moles of NaCl will it take to make 3.0 L of<br> a 0.1 M solution?
Ilia_Sergeevich [38]

Answer:

0.30 mole NaCl needed.

Explanation:

From the definition of solution molarity => Molarity = moles solute / Volume of Solution in Liters => Molarity = moles/Volume(L) => solve for moles =>

moles = Molarity X Volume(L) = (0.1M)(3.0L) = 0.30 mole NaCl needed.
