If CI-35 has 18 neutrons, how many neutrons are

Chemistry
1 answer:
torisob [31]3 years ago
3 0

Answer:

B. 16

Explanation:

Cl -35 and Cl-33 have the same number of protons because it is the same element Cl.

Their masses are different because they have different number of neutrons.

Cl- 33 has 2 neutrons less than Cl-35.

35 - 33 = 2

If Cl-35 has 18 neutrons, then Cl-33 has 18-2=16 neutrons.

Most foods that are high in calcium are poor sources of iron. this statement illustrates the characteristic of a nutritious diet
natka813 [3]

Most foods that are high in calcium are poor sources of iron. this statement illustrates the characteristic of a nutritious diet known as balance.

Nutrition is the biochemical and physiological processes by which organisms use food to sustain life. It provides organisms with nutrients that can be metabolized to produce energy and chemical structures. An inadequate supply of nutrients leads to malnutrition.

Although these two definitions may seem similar, there are differences. Health simply means food that protects you from disease and keeps you alive. Nutrient-rich foods mean foods that provide sufficient nutrients (vitamins, carbohydrates, proteins) that the body needs to survive the kind that is either low in fiber or high in fat, salt, and/or sugar. Eating too much food or drink.

What is the atomic number of an atom that has 2 electrons 3 protons and 4 neutrons
zalisa [80]
Hi,
The atomic number of an element depends on how many protons there are in one atom of that element. If the atom has 3 protons, its atomic number will be 3.

Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know.

Which of the following nuclei would be the most stable?
ValentinkaMS [17]
Ten protons would be Neon, but the most stable? I'd have to say 12 neutrons in contrast to the 10 protons.  Not too negative in balance.

Answer :

Part 1 : Balanced reaction, 3H_2(g)+N_2(g)\rightarrow 2NH_3(g)

Part 2 : The theoretical yield of NH_3 gas = 440.96 g

Part 3 : The % yield of ammonia is 90.03 %

Solution : Given,

Mass of N_2 = 475 g

Molar mass of N_2 = 28 g/mole

Molar mass of NH_3 = 17 g/mole

Experimental yield of NH_3 = 397 g

<u>Answer for Part (1) :</u>

The balanced chemical reaction is,

3H_2(g)+N_2(g)\rightarrow 2NH_3(g)

<u>Answer for Part (2) :</u>

First we have to calculate the moles of N_2.

\text{Moles of }N_2=\frac{\text{ Mass of }N_2}{\text{ Molecular mass of }N_2}=\frac{475g}{28g/mole}=16.96moles

From the given reaction, we conclude that

1 moles of N_2 gas react to give 2 moles of NH_3 gas

16.96 moles of N_2 gas react to give \frac{2}{1}\times 16.96=33.92 moles of NH_3 gas

Now we have to calculate the mass of NH_3 gas.

\text{ Mass of }NH_3=\text{ Moles of }NH_3\times \text{ Molar mass of }NH_3

\text{ Mass of }NH_3=(33.92moles)\times (17g/mole)=440.96g

Therefore, the theoretical yield of NH_3 gas = 440.96 g

<u>Answer for Part (3) :</u>

Formula used for percent yield :

\% \text{ yield of }NH_3=\frac{\text{ Experimental yield of }NH_3}{\text{ Theoretical yield of }NH_3}\times 100

\% \text{ yield of }NH_3=\frac{397g}{440.96g}\times 100=90.03\%

Therefore, the % yield of ammonia is 90.03 %
