mafiozo [28]1 year ago
7 0

This thermochemical equation needs to be balanced. Hence, option B is correct.

<h3>What is a balanced chemical equation?</h3>

A balanced equation contains the same number of each type of atom on both the left and right sides of the reaction arrow.

The balanced thermochemical equation is:

H_2(g) + 2NaCl (s) + 3O_2 (g) → 2HCl (l) + 2Na (s) + 2O_3 (g)

Hence, option B is correct.

Why is frying an egg an example of a chemical change
skelet666 [1.2K]
A Chemical change is any form of chemical reaction changing the state of the matter involved. When you fry an egg, you are making a reaction between the heat and the chemicals that make up the egg. Therefore once you have fried that egg, you have completed a chemical reaction. This is why it's a chemical change when you fry an egg.

sodium ions are moving with their concentration gradient with the use of a protein channel across a plasma membrane. Determine t
jeka57 [31]

Answer:

Explanation:

When there is difference between the concentration of the content of a cell and the solution surrounding the cell, there will be an Electrochemical gradient or Concentration gradient. Therefore, some solute will tend to move from the region of high concentration to the region of lower concentration through the cell membrane.

Such a movement is called Primary Active Transport

A chemist must calculate the amount of an element needed for a chemical reaction. The reaction requires 3.4 moles of silver. Hel
zvonat [6]

Answer:

3.4 moles of silver * 107.868 grams of silver/1 mole of silver = 370 grams of silver.

Explanation:

According to the NYS Reference Table, one mole of silver equates to 107.868 grams. Therefore, if you want to convert from moles to grams, the mole unit should be on the bottom, since it is the unit being cancelled out. Above the mole unit should be the gram unit, since it is the unit you want to convert to. Once you do the math with significant figures, the solution turns out to be 370 grams of silver.
