If the products contain 3 nitrogen atoms, then so did the reactants since overall mass is conserved in a chemical reaction.

Sample response:

There would have to be three nitrogen atoms in the products. The law of conservation of matter states that the amount of substance before a reaction occurs should be the same as the amount of substance after the reaction.

hope this helps! Have a great one :D

How do scientists believe that chloroplasts got into photosynthetic cells? ​
Lera25 [3.4K]

The development of chloroplast is thought to occur through endosymbiosis.

According to the endosymbiosis, some of the organelles found in modern eukaryotic cells, such as mitochondria and chloroplasts, were previously prokaryotic microorganisms. A non-photosynthetic creature acquired one photosynthetic cell, and the chloroplast was subsequently created.

An organelle known as a chloroplast is crucial to the process of photosynthesis in plants. It contains pigments like chlorophyll and other  pigments that are in charge of capturing sunlight. Since each chloroplast has two membranes, other organelles such as mitochondria are referred to as double-membrane organelles. It is believed that cyanobacterial endosymbiosis played a role in the genesis of the chloroplast. Prokaryotic organisms like cyanobacteria have the capacity to prepare their food through the process of photosynthesis.

If you were to mass the reactants before a reaction and then mass the products after the reaction what would you expect to find
TiliK225 [7]

Answer:

No change...

Explanation:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

When copper ii chloride reacts with sodium nitrate copper ii nitrate and sodium chloride are formed?
Nesterboy [21]
The balanced chemical reaction would be written as follows:

CuCl2 + 2NaNO3 = Cu(NO3)2 + 2NaCl

This is an example of a double displacement type of reaction where the ions of the reactants displaces each other forming two new substances. Hope this answers the question.
