Answer:
7.75 Calories per gram of candy
Explanation:
The equation of a calorimeter is:
Q = C×ΔT
Where Q is heat involved in the reaction, C is heat capacity of the calorimeter (46.80kJ K⁻¹) and ΔT is change in temperature (2.91°C). Replacing:
Q = 46.80kJ K⁻¹ ₓ 2.91K
Q = 136.2 kJ are produced. If 4.184 kJ = 1kCal:
136.2 kJ ₓ (1kCal / 4.184 kJ) = <em>32.55 kCal per 4.20g of candy. </em>Thus, Calories / g of candy are:
32.55 kCal / 4.20g = <em>7.75 Calories per gram of candy</em>
<span> rate 3/1= square root of 32/x
square both sides
9/1=32x
x = 32/9
= 3.6

One mole of an ideal gas will occupy 22.4 liters of volume at STP.
If the only thing that changes is the pressure from 1.00 atm to 2.00 atm, then we know the initial volume, initial pressure, and final pressure. We can use Boyle's law.
Boyle's law: (initial pressure)*(initial volume) = (final pressure)*(final volume)
fill in the knowns
(1.00 atm)*(22.4 liters) = (2.00 atm)(final volume)
divide both sides by 2.00 atm
11.2 liters = final volume
Living things are a resource for humans. They are a renewable resource because they reproduce. A forrest that has been cut down can regrow and animals can give birth to babies.
A only gets out some of it but not all
C that isn't for alcaholl
D I don't think that even exists
B is the only correct answer
