Answer:
D - Any substance to the right of the arrow.
Explanation:
A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.
(NH4)3PO4 :
N = 14 * 3 = 42
H = 1 * 12 = 12
P = 31 * 1 = 31
O = 16 * 4 = 64
-------------------------
42+12+31+64 = 149 g / mol
Hope this helps!.
2.50 moles (55.85gramsof Fe/ 1 mole) (6.02 x 10^23 atoms / 1) = 8.41 x 10^25 because there is only one Iron present in the compund.
In the tables you can find that the empirical radius of a gold atom is 135 pm.
That is 135*10^-12 m.
Then the diameter is two times that: 270*10^-12 m.
Now calculate how many times that is 6.5 mm = 6.5*10^-3 m
=> (6.5*10^-3 m) / (270*10^-12 m) = 24,074,074.
Answer: 24,074,074
Answer:
Gay-Lussac's law, Amontons' law or the pressure law was found by Joseph Louis Gay-Lussac in 1809.
Explanation:
It states that, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.
