An environmental scientist studies the environment - you can see that in the beginning of the sentence :)
Answer:
0.2298kg of Al
Explanation:
From the equation of reaction
3 moles of Al (81g) is required to mix with 3 moles of NH4ClO4 (352.5g)
Mass of Al required in the fuel mixture for every kilogram (1000g) of NH4ClO4 = 1000×81/352.5 = 229.8g = 229.8/1000 = 0.2298kg
Answer:
K=CHANGE IN CONCENTRATION/TIME TAKEN
Explanation:
Answer:
yes
Explanation:
the components of solutions fixed
Explanation:
Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.
