Answer:
0.244 M.
Explanation:
From the question given above, the following data were obtained:
Molarity of stock solution (M₁) = 1 M
Volume of stock solution (V₁) = 0.305 L
Volume of diluted solution (V₂) = 1.25 L
Molarity of diluted solution (M₂) =?
The molarity of the diluted solution can be obtained by using the dilution formula as illustrated below:
M₁V₁ = M₂V₂
1 × 0.305 = M₂ × 1.25
0.305 = M₂ × 1.25
Divide both side by 1.25
M₂ = 0.305 / 1.25
M₂ = 0.244 M
Thus, the molarity of the diluted solution is 0.244 M
Answer:
4 NH3 (g) + 5 O2 (g) → 4 NO (g) + 6 H2O (l)
This is an oxidation-reduction (redox) reaction:
4 N-III - 20 e- → 4 NII
(oxidation)
10 O0 + 20 e- → 10 O-II
(reduction)
NH3 is a reducing agent, O2 is an oxidizing agent.
Explanation:
good luck
Neon is the element that is classified as a noble gas at STP.
I think the correct answer from the choices listed above is option 1. The list that includes three forms of energy would be chemical, mechanical and electromagnetic. Pressure and temperature are not energy. Hope this answers the question. Have a nice day.
Answer:
A
both forms of energy referred to in the question is light and heat energy
light energy is the visible energy that travels at a known constant speed of 3.0×10^9m/s
while heat energy is the invisible energy that travels in form of radiation at variable speeds
