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>
Answer:
174,957.143 grams of potassium and 89,228.478 grams of potassium nitrate will be needed.
Explanation:
Mass of nitrogen = 27 lbs = 12,247 g
1 lbs = 453.592 g
Moles of nitrogen = 
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 :
of potassium.
Then 874.786 mol of nitrogen will be obtained from :
of potassium nitrate.
Mass of 4,373.928 moles of potassium:
of potassium
Mass of 874.789 moles of potassium nitrate:
of potassium nitrate
Answer:
Infrared radiation lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves have wavelengths longer than visible and shorter than microwaves, and have frequencies which are lower than visible and higher than microwaves
