Answer:

I don't wanna intrigue but I think this is how you want things to go. But to make it easier all you have to do is look up "what is genomics" and then simply answer each question should take maybe 5-7 minutes. Just trying to help :)

21. A piece of metal with a a mass of 15.2 g is heated from 17°C to 42°C. In the process it absorbs 1362 J of
Sholpan [36]

Answer:

3.58J/g°C is the specific heat of the metal

Explanation:

The specific heat of a material is defined as the energy that 1g of the material absorbs and produce the increasing in temperature in 1°C. The equation is:

Q = S*ΔT*m

<em>Where Q is energy = 1362J</em>

<em>S is specific heat of the material</em>

<em>ΔT is change in temperature = 42°C - 17°C = 25°C</em>

<em>And m is the mass of the material = 15.2g</em>

Replacing:

S = Q / ΔT*m

S = 1362J / 25°C*15.2g

<h3>3.58J/g°C is the specific heat of the metal</h3>

5K + KNO3 ------ 3K2O + N
masya89 [10]

Answer:

174,957.143 grams of potassium and 89,228.478 grams of potassium nitrate will be needed.

Explanation:

5K +KNO_3\rightarrow 3K_2O + N

Mass of nitrogen =  27 lbs = 12,247 g

1 lbs = 453.592 g

Moles of nitrogen = \frac{12,247 g}{14 g/mol}=874.786 mol

According to reaction, 1 mole of nitrogen is produced from 5 moles of potassium and 1 mole of potassium nitrate.

Then 874.786 mol of nitrogen will be obtained from :

\frac{5}{1}\times 874.786 mol=4,373.928 mol of potassium.

Then 874.786 mol of nitrogen will be obtained from :

\frac{1}{1}\times 874.786 mol=874.789 mol of potassium nitrate.

Mass of 4,373.928 moles of potassium:

4,373.928 mol\times 40 g/mol=174,957.143 g of potassium

Mass of 874.789 moles of potassium nitrate:

874.789 mol\times 102 g/mol=89,228.478 g of potassium nitrate
