Hydroxide ion concentrstion in bleach is higher
Answer:
Common ones are Gasoline, Diesel fuel, and Kerosene.
Explanation:
Many accelerants are hydrocarbon-based fuels, sometimes referred to as petroleum distillates: gasoline, diesel fuel, kerosene, turpentine, butane, and various other flammable solvents. These accelerants are also known as ignitable liquids. Ignitable liquids can leave behind tell-tale marks in the fire debris.
Hoped this had helped you :)
Answer:
0.25M
Explanation:
The formula of concentration is c=m/M•V
c=1.85g/74g.mol•0.10L
c=0.25 M
Answer:
1. A diprotic acid was neutralized.
2. HCl has the ability to accept two protons.
Explanation:
Hello,
Neutralization chemical reactions are better quantified by using equivalent grams instead of moles since they define the mass of a given substance which will neutralize the other substance, thus, in the first, experiment, 1 mole of NaOH has 1 equivalent grams since there's just one hydroxile in its structure, on the other hand, as 2.00 L of a 1.00 M solution of NaOH were needed to neutralize 1.00 L of a 1.00 M solution of an acid, one concludes that the acid was diprotic, it means that it has two hydrogens in its structe.
In such a way, in the second experiment, it was the other way around but by using the hydrochloric acid as it has the ability to accept two protons, it means that the base had two hydroxile ions in its structure.
Best regards.
Data:
m = 7 g
ΔT = 19 °C
Cs of water = 1 cal / g °C
Formula Q = m * Cs * ΔT
Solution:
Q = (7 g) * (1 cal / g °C) * ( 19°C) = 133 cal
