Answer: 25°C=77°F
Explanation:
FORMULA
F=9/5 C+32
-----------------------------------
Given: C=25°
F=9/5 C+32
F=9/5 (25)+32
F=45+32
F=77°

Answer:
D working alone
Explanation:
Working alone is the only option that could potentially be a safety hazard; if you have no one watching your back, errors could occur, like dropping glass or burning your hand, and no one is around to help you.

Answer:
11.55 mol ≈ 11.6 mol CO2
Explanation:
C3H8 (g) + 5O2(g) → 3CO2 (g) + 4H2O(g)
from reaction 1 mol 3 mol
given 3.85 mol x mol
Solving proportion
x =(3.85*3)/1 = 11.55 mol ≈11.6 mol
Answer:
2 chlorine atoms.
Explanation:
H₂ + Cl₂ → 2HCl
The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.
If 2 molecules of Hydrogen and 2 molecules of Chlorine is present in the reactants, the same no. of atoms should also be present in the product.
∴ the no. of chlorine atoms in the product is 2.
The subatomic particle James Chadwick discover is no other than NEUTRON. Neutron is a subatomic particle discovered by James Chadwick, its symbol n or n0 and it has no net electric charge. When we compare its mass to that of proton, the neutrons mass is slightly greater than the proton.
