A reaction of 17.0 g of ammonia with 26.6 g of chlorine gas
produces 3.50 g of nitrogen. What mass of ammonium chloride
is produced in the reaction?
Answer: if doing it on ck-12 the answer is 40.1
Explanation:
There are produced 40.1 grams of ammonium chloride (NH₄Cl) in the reaction between 17.0 g of ammonia (NH₃) and 26.6 g of chlorine gas (Cl₂).
The reaction between ammonia and chlorine gas is the following:
8NH₃ + 3Cl₂ → 6NH₄Cl + N₂
Initially, we have:
[tex]m_{NH_{3}}[/tex]: mass of ammonia = 17.0 g[tex]m_{Cl_{2}}[/tex]: mass of chlorine gas = 26.6 g[tex]m_{N_{2}}[/tex]: mass of nitrogen = 3.50 gAccording to the conservation of mass, matter cannot be created or destroyed, only can be transformed, so the mass of the reactants must be equal to the mass of the products.
The mass of ammonium chloride produced is:
[tex] m_{r} = m_{p} [/tex]
[tex] m_{NH_{3}} + m_{Cl_{2}} = m_{NH_{4}Cl} + m_{N_{2}} [/tex]
[tex] 17.0 g + 26.6 g = m_{NH_{4}Cl} + 3.50 g [/tex]
[tex] m_{NH_{4}Cl} = 17.0 g + 26.6 g - 3.50 g = 40.1 g [/tex]
Therefore, 40.1 grams of ammonium chloride are produced in the reaction.

20 ml of a solution of sucrose contains 850 mg of sucrose. What is the weight/volume percentage concentration of this solution in g/ml%
Explanation:
weight/volume percentage concentration = (mass in g ÷ volume) × 100
= (0.850 g ÷ 20 ml) × 100
= 4.25 g/ml %
∴ the weight/volume percentage concentration of the sucrose solution is 4.25 g/ml %.

Questiondescribe atom in your own words
AnswerThe atom is the smallest unit of an element that retains the properties of that element.
Explanation:
At the center of the atom, there is a very small region called the nucleus. This area makes up most of the mass of the atom.The area around the nucleus is called the electron cloud. This area makes up the majority of the volume of the atom. The electron cloud is mostly empty space.

Why the melting point of sodium chloride is higher than naphthalene
Answer:
This is because sodium chloride has electrostatic forces of attraction and thus this tends to hold the the sodium and chloride ions very strongly and thus responsible for the high melting point. Sodium chloride is very soluble in water than naphthalene.
