Answer:
[H+] =3.1 x 10-4 M more acidic
Explanation:
3.1 x 10-4 M >> 2.5 x 10-10 M,
so solution with [H+] =3.1 x 10-4 M has more H+ ions, and because of it, this solution is more acidic.
Answer:
5.20 grams of Br₂
Explanation:
From our previous knowledge;
We understand that:
The number of moles of a given element = mass of the element divided by its molar mass.
Mathematically:
From the given information, let's assume that the 0.065 moles of liquid -bromine partake in the reaction.
From the periodic table, the molar mass of Bromine is = 79.9 g/mol
As such, the mass of liquid that partakes is calculated as:
0.065 mol = mass/ 79.9 g/mol
mass = 0.065 mol × 79.9 g/mol
mass of liquid that partakes in the reaction = 5.20 grams of Br₂
Answer:
It would be E. A small yellow ball that represents the Sun Reset Next i got the answer from somebody else
Explanation:
hope this helps :)
The first question the mass of Zinc would be 104g
152-64 =88
192-88=104
The second question the mass would be 159g
127+32 =159g
