We can solve the equation and show the solution below:
Oxygen atomic number is 16.
Phosphorus atomic number is 32.
We have the molecular weight:
Molecular weight = (31*4) + (16*10)
Molecular weight = 284 grams/mol
Solving for the grams:
0.4 mole (for P4) * (1 mol P4O10/1 mol P4) * (284 grams P4O10/1 mole P4O10)
Total grams = 113.6
The answer is 113.6 grams.
Answer:
D) 15375kgm/s
Explanation:
weight of the boy 25kg +weight of the car 1000kg= 1025kg so momentum =mass × velocity. so it's SI unit is = kg×m/s = kg m/s.
Answer: a) 90.5g
b) 33.6 L
Explanation:-
Molar mass of tyrosine 
= 181 g/mol
According to Avogadro's law, 1 mole of every substance weighs equal to its molar mass.
1 mole of tyrosine weighs = 181 g/mol
0.5 moles of tyrosine weigh 
b) According to Avogadro's law, 1 mole of an ideal gas occupies 22.4 Liters at Standard conditions of temperature and pressure (STP).
1 mole of gas at STP occupy = 22.4 L
1.5 moles of gas at STP occupy =
Answer: 13.31 moles.
Explanation: So take 452 grams of Argon and multiply by the molar mass of Argon. Your units will cancel out, leaving you with moles of Argon.
So, water reacts with hydrochloric acid in the following formula
H2O + HCl —-> H3O+ + Cl-
We can visualize that when the two react, the hydrogen ions is taken on by the water molecule. This satisfies one of the definitions for a base
Bronsted acids = anything that donates a proton (H+ ion)
Bronsted bases = anything that accepts a proton (H+ ion)
So, as we can see, that is exactly what is happening. The Cl- and H+ detach and then the water takes on that extra H+.
H3O+ is what we call a hydronium ion
