g Consider the reaction when aqueous solutions of potassium hydroxide and ammonium bromide are combined. The net ionic equation
vichka [17]

Answer:

K^+(aq) + Br^-(aq) -----> KBr(aq)

Explanation:

The net ionic equation shows the actual reaction that occurs in the system. The molecular reaction equation includes the spectator ions but the net ionic equation does not include the spectator ions.

Spectator ions do not participate in the main reaction going on in the system.

Hence, for the reaction of potassium hydroxide and ammonium bromide, we have;

K^+(aq) + Br^-(aq) -----> KBr(aq)

Y = 57.15 − 0.5 X If Y equals 5 , what is X ?<br><br> Then is Y=3, what is X?
Fiesta28 [93]

When y equals 5, x is 104.3

When y equals 3 then x is 108.3

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

y = 57.15 - 0.5x

<h3><u>If y equals 5 what is x ?</u></h3>

Substitute y = 5 in given expression

5 = 57.15 - 0.5(x)

5 = 57.15 - 0.5x

0.5x = 57.15 - 5

0.5x = 52.15

Divide both sides by 0.5

x = 104.3

Thus when y equals 5, x is 104.3

<h3><u>If y = 3 what is x ?</u></h3>

Substitute y = 3 in given expression

3 = 57.15 - 0.5(x)

3 = 57.15 - 0.5x

0.5x = 57.15 - 3

0.5x = 54.15

Divide both sides by 0.5

x = 108.3

Thus when y equals 3 then x is 108.3

Identify this vocabulary word: the process of breaking down glucose for the production of ATP
Aloiza [94]

Answer:

Cellular respiration

Explanation:

Fermentation is a mechanism in anaerobic respiration(breaking down glucose in the absence of oxygen). Examples are lactic acid fermentation is humans, Alcohol fermentation in yeast.

Cellular respiration sums up both anaerobic and aerobic(with oxygen)

Metabolism is just breaking down food molecules chemically into their simplest forms (monomers). These monomers then undergo cellular respiration to produce ATP
