Answer:
The percent composition for nitrogen in chromium(III) nitrate is 6%.
Explanation:
Answer: I think it's 1
Explanation: Potential energy means stored energy . In Position 1 it's not moving the energy is being stored. Hope that helps.
Answer:
The new pressure in the balloon is 16.3 atm
Explanation:
Gay-Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant.
This law establishes that pressure and temperature are directly proportional quantities, that is to say that if the temperature increases the pressure increases and if the temperature decreases the pressure decreases.
Mathematically, Gay-Lussac's law states that, when a gas undergoes a constant volume transformation, the quotient of the pressure exerted by the gas temperature remains constant:
When you want to study two different states, an initial one and a final one, of a gas, you can use the expression:
In this case:
- P1= 14.7 atm
- T1= 273 K
- P2= ?
- T2= 303 K
Replacing:
Solving:
P2= 16.3 atm
<u><em>The new pressure in the balloon is 16.3 atm</em></u>
Answer:
2.677 J/g°C
Explanation:
Quantity of heat required to raise the temperature of the metal,
Q = mc∆T
where m is the mass of the metal, c is the metal's specific heat capacity, and ∆T is the change in temperature that accompanies the heat transfer process
20.0J = 50.0g × c × 150°C
c = 20.0J/(50.0g × 150°C)
c = 2.677 J/g°C
Answer:
5.0 carat x (0.200g / 1 carat) x (1 cm³ / 3.51g) = 0.28 cm³... with 2 sig figs..
Explanation:
USE DIMENSIONAL ANALYSIS. That is the point of this problem. That is why Dr. Zumdahl wrote this problem and put it in his textbook (chpt 1 Problem #57 if you're using the 7th edition, chpt1 problem #63 if you're using his 8th edition).
