Chemistry
1 answer:

Answer:

= 49.674 g NaCl

Explanation:

From the equation;

1 mole of Sodium metal produces 2 moles sodium chloride

This means;

23 g of Na will produce 116.88 g of NaCl

Therefore;

11.5 g will generate;

 = (11.5 × 116.88)/23

 =  58.44 g of NaCl

But;

Percentage yield = (Actual yield/Theoretical yield)× 100%

         85 /100 = Actual yield /58.44 g

Thus;

Actual yield = 0.85 × 58.44

                  = 49.674 g NaCl

Is it possible for two or more elements to have the same number of protons? Why?​
muminat

Answer:

No

Explanation:

Hello!

Only one element can have the same number of protons.

Proton amount is basically like the DNA of a proton; it makes them what they are.

When elements are isotopes instead, their neutron count changes but their protons remain the same.

For example, all carbons have 6 protons regardless of if they are an isotope or not. A carbon-12 and a carbon-14 will still have 6 protons, but different amount of neutrons.

Distinguishing ionic, molecular and atomic solids web activity
ahrayia [7]

Answer:

The difference lies in the kind of bond involved.

Explanation:

An ionic solid is composed of a network of oppositely charged ions such as sodium chloride solid. An atomic solid is formed by covalent linkage of atoms of the same element to form a three dimensional solid structure such as in diamond and graphite. A molecular solid consists of discreet molecules held together by intermolecular forces. Examples of molecular solids include naphthalene and the fullerenes.

a chemical company claims that they are able to produce a certain product thermodynamically unfavored process. Explain how this
KonstantinChe [14]
Thermodynamically favored process are those processes that do not require any assistance from outside the system e.g water boils at 25 degrees. Thermodynamically unfavored processes require assistance from outside to induce the required change for example water doesn't freeze at 15 degrees and therefore for that to happen several factors in the system have to be modified to achieve this. Therefore, there is a possibility of companies to produce product by using thermodynamically unfavored process by inducing changes in the system to achieve desired change or modification.

Consider the reaction below. CO(g) + Cl2(g) « COCl2(g) What is the most likely effect to the forward reaction if there is an inc
marysya [2.9K]
Answer: the reaction rate of the forward reaction increases (although it is not among the options shown).

Explanation:

1) The equation given is:

CO (g) + Cl₂ (g)  ⇄ COCl₂ (g)

2)  The forward reaction is:

CO (g) + Cl₂ (g)  → COCl₂ (g)

3) The stoichiometry is 1 mole + 1 mole → 1 mole

4) Analysis and conclusion:

The effect of change in the conditions of an equilibrium is foreseen using Le Chatelier's principle.

Le Chatelier's principle states that a system in equilibrium will act trying to compensate the distress applied to the system.

In this case, the distress is increase in pressure.

To compensate the increase in pressure the system must act by reducing the number of moles in the system. Since the forward reaction implies the conversion of two moles of reagents into one mole of product, the more the forward reaction progress the less the number of moles will be present in the system and so the more the compensation of the increase in pressure. So the forward raction is favored by the increase in pressure.

Favoring the forwar reaction means that its rate will incrase,
