Answer:
82.04g
Explanation:
To solve this problem, you need to find the molar mass of HCl, which is the sum of the molar mass of H plus the molar mass of Cl. The molar mass of H is 1.008g/mol while the molar mass of Cl is 35.45g/mol. Thusly the molar mass of HCl is 36.458g/mol. You have 2.25 moles of HCl, so multiply the number of moles by the molar mass to get the mass in g. In this case it is 2.25mol * 36.458g/mol = 82.04g.
If I helped, a brainliest would be greatly appreciated!
Answer:
=> 0.10 moles
Explanation:
The question is asking us to find the moles of NaCl cid formed.
We have been provided with;
0.10 L of 1.0 M NaOH.
We know that mole ratio of the reaction is 1:1 and also the molarity of a solution is contained in 1 L or 1000 mL or 1000 cm³.
This means that;
1.0 M is contained in 1.0 L.
X mol is contained in 0.10 L
= 0.10 moles of NaCl formed
Answer:
Option B, Al --> Al3+ + 3e-
Explanation:
Oxidation is defined as the process of losing electron by a molecule, atom or anion thereby acquiring oxidation state i.e the positive charge. Reduction on the other hand is the process in which an atom, ion or molecule gains electron and gains negative charge on it.
For example – In the reaction, H2 + F2 → 2 HF, hydrogen is oxidized H2 → 2 H+ + 2 e- as it looses electron while fluorine is being reduced F2 + 2 e- → 2 F-
This is happening in the option B
43.97/12.01=3.661=2
10.51/1.01=10.406=5
39.52/19.00=2.075=1
