Slicing carrotsin a chemical reacționat the reactants, which are on the left side of the equation should become something else which are the products on the right side of the equation!
You get nothing but also carrot when slice it up but for example frying an egg due to the heat, chemical energy, you get scrambled egg or whatever!

julsineya [31]

Answer:

0.10 moles of oxygen produced by the reaction of 0.10 of water.

Explanation:

The photosynthesis reaction is given by :

6CO_2(g)+6H_2O(l)\rightarrow C_6H_{12}O_6(aq)+ 6O_2(g)

Moles of water = 0.10 mole

According to reaction, 6 moles of water gives 6 moles of oxygen gas,then 0.10 moles of water will give :

\frac{6}{6}\times 0.10 mol=0.10 mol of oxygen gas

0.10 moles of oxygen produced by the reaction of 0.10 of water.

Why does the temperature of different layers of the atmosphere vary
scoundrel [369]
It has different reasons. the temperature difference is basically the main reason why the earth atmosphere has layers.
Theoretically the temperature varies because of the different molecules and atoms. for instance the first layer known as troposphere has the greenhouse effect of CO2,CH4, etc. and is covered with a layer of O3...

The following reaction has Kp = 109 at 25°C. 2 NO(g) + Br2(g) equilibrium reaction arrow 2 NOBr(g) If the equilibrium partial pr
kati45 [8]

<u>Answer:</u> The equilibrium partial pressure of NO is 0.0034 atm

<u>Explanation:</u>

For the given chemical equation:

NO(g)+Br_2(g)\rightleftharpoons 2NOBr(g)

The expression of K_p for above equation follows:

K_p=\frac{(p_{NOBr})^2}{p_{NO}\times p_{Br_2}}

We are given:

Equilibrium partial pressure of Br_2 = 0.0159 atm

Equilibrium partial pressure of NOBr = 0.0768 atm

K_p=109

Putting values in above equation, we get:

109=\frac{(0.0768)^2}{p_{NO}\times 0.0159}\\\\p_{NO}=0.0034atm

Hence, the equilibrium partial pressure of NO is 0.0034 atm
