The reason why is because frost is a result of a chemical reaction

Chemical Change is also known as the Non Reversible Change. ... Reversible Change is defined as changes that can be reversible. For example, frost forming on the window is Physical. It is because when the temperature goes up, the frost can melt and when it freezes, it forms a frost again

6. The Haber process for making ammonia (NH)
gas from its elements was developed by Fritz Haber
during WWI. Haber hoped to use ammonia as
fertilizer to grow food for Germany during the
Allie's blockade. How many liters of hydrogen
would be required to produce 40.0L of ammonia at
STP? N+H, NH,

Answers

Answer:

60 Liters

Explanation:

The equation for this reaction is given as;

N2 + 3H2 → 2NH3  

From the reaction;

3 mol of H2 produces 2 mol of NH3

At STP;

1 mol = 22.4 L

This means

67.2 L ( 3 * 22.4) of H2 produces 44.8 L ( 2 * 22.4) of NH3

How many L of H2 would produce 40 L of NH3

67.2 = 44.8

x = 40

Solving for x;

x = 40 * 67.2 / 44.8

x = 60 L

A. Oxygen turned in to carbon dioxide
B. Sulphate and lithium boiled
C. Decomposition of potassium permanganate(Heating)
D. None of the above​

Answers

Answer:

C. Decomposition of potassium permanganate(Heating)

Explanation:

The equation of the reaction is given as;

2KMnO4 -> K2MnO4 + MnO2(s)  + O2(g)

Reactant = 2KMnO4

Products = K2MnO4 + MnO2(s)  + O2(g)

A. Oxygen turned in to carbon dioxide

Incorrect option - Oxygen is not the reactant

B. Sulphate and lithium boiled

Incorrect option -  Sulphate and lithium are not part of this reaction

C. Decomposition of potassium permanganate(Heating)

Correct option - potassium permanganate decomposed to form K2MnO4 + MnO2(s)  + O2(g)

D. None of the above

Incorrect option

Nitric monoxide (NO) reacts with oxygen gas to form nitrogen dioxide (NO₂), a dark brown gas. If 5.895 mol of NO is mixed with 2.503 mol of O₂,

determine the limiting reagent.

calculate the number of grams of NO₂ produced.

and determine how many grams of excess reagent remain unreacted.

Answers

Answer:

Limiting reactant: O2

grams NO2 produced = 230.276 g NO2

grams of NO unused = 26.67 gNO

Explanation:

2NO + O2 --> 2NO2

Step 1: Determine the molar ratio NO:O2

molar ratio NO:O2 = 5.895: 2.503 = 2.35

stoichiometric molar ratio NO:O2 = 2:1

So, O2 is the limiting reactant.

Step2: Determine the grams of NO2:

?g NO2 = moles O2 x (2moles NO2/1 mol O2) x (MM NO2/ 1 mol NO2) = 2.503 x 2 x 46 = 230.276 g NO2

Step 3: Determine the amount of excess reagent unreacted

moles excess NO reacted = moles O2 x (2 moles NO/1 mol O2) = 2.503 x 2 = 5.006 moles NO reacted

moles NO unreacted = total moles NO - moles NO reacted = 5.895-5.006 =0.889 moles NO unreacted

mass NO unreacted = moles NO unreacted x MM NO = 0.889 x 30 =26.67 g NO unreacted

Answers

The concept of significant figures are mainly used by scientist and engineer to know the significance of digits in a measurement. Therefore, 3,545,530 upto 3 significant figures is 3.54 x 10³.

What is significant figures?

Significant figures are the figures that indicate the degree of accuracy of a value. It tells about the precision of a value. It gives an idea about the digits that are necessary to indicate the experimental value.

Rules for counting significant figures are:

Number between 1 to 9 is always significant

Zeroes after a number has got no significance

Zeroes before a number has got no significance

Zeroes between number has got significance

3,545,530 upto 3 significant figures is 3.54 x 10³.

How many grams are in 8.50 e 23 formula units of NaCl?
a)82.5 g
b)8.25 g
c)85.0 g
d)91.5 g

Answers

Answer:

a)82.5 g

Explanation:

To solve this problem we will use Avogadro's number, which states the number of formula units per mole.

8.50x10²³formula units ÷ 6.023x10²³ formula units/mol = 1.41 mol

Then we convert 1.41 moles of NaCl to grams, using its molar mass:

1.41 mol NaCl * 58.44 g/mol = 82.4 g
