Answer:
1254 J
Explanation:
Mass, m = 10.0g
Initial Temperature = 20°C
Final Temperature = 50°C
Energy = ?
Specific heat capacity, c = 4.18 J/g·°C
The relationship between these quantities is given by the equation;
H = mcΔT
ΔT = Final Temperature - Initial Temperature = 50 - 20 = 30 °C
H = 10 * 4.18 * 30
H = 1254 J
Answer:
When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another.
Explanation:
Answer: 5. Determine the number of atoms that are in 0.58 mol of Se. 0.58molo se x 6.02x1020 g tors Se - 3.5X1023 atoms Se 1 mol of Se 6.
Explanation:
Answer:
Your answer would be C.
Explanation:
Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.
Answer:
48 molecules of CO₂
Explanation:
I think you made a mistake in your question. The formula for propane is C₃H₈, not C₃H₃. But, I will give you the answer for both cases.
For C₃H₃:
First you have to balance the equation.
4 C₃H₃ + 15 O₂ ⇒ 12 CO₂ + 6 H₂O
Next, you need to use the mole ratios between C₃H₃ and CO₂ to find the amount of molecules of CO₂ you will produce with the given amount of C₃H₃.
(16 mol's C₃H₃) × (12 mol's CO₂/4 mol's C₃H₃) = 48 mol's CO₂
You will get 48 molecules of CO₂.
For C₃H₈:
Balance the equation.
C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O
Use the mole ratios between C₃H₈ and CO₂.
(16 mol's C₃H₈) × (3 mol's CO₂/1 mol's C₃H₈) = 48 mol's CO₂
You will get 48 molecules of CO₂ for this equation as well.
