Answer:
The volume of hydrogen gas produced at STP is 4.90 liters.
Explanation:

Moles of aluminium =
According to reaction , 2 moles of aluminium gives 3 moles of hydrogen gas.
Then 0.1333 moles of aluminium will give:
of hydrogen gas
Volume of 0.2 moles of hydrogen gas at STP = V
Temperature at STP = T = 298.15 K
Pressure at STP = P = 1 atm
n = 0.2 mol
PV = nRT (Ideal gas equation)

The volume of hydrogen gas produced at STP is 4.90 liters.
Answer:
We use the following formula as given below Use the formula below to find the lone pair on the oxygen atom of the SO3 molecule. L.P (O) = V.E (O) – N.A (S-O) Lone pair on the terminal oxygen atom in SO3 = L.P (O)
Explanation:
Answer:Salt
Explanation:
In chemistry a salt is produced from a neutralization reaction, when an acid react with a base.
HCl(aq) + NaOH (aq) ----> NaCl (aq) + H2O(l)
A salt consists of the positive ion (cation) of an acid and the negative ion (anion) of a base.
H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) -------> Na+Cl-(aq) + H2O(l)
When the water is evaporated, the negatively charged chlorine ions combine with the positively charged sodium ions to form a solid salt.
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
There are 3 subatomic orbitals which are present in an atom:
1. Protons: These sub-atomic particles are positively charged and are found in the nucleus.
2. Electrons: These sub-atomic particles are negatively charged and are found in the orbitals around the nucleus.
3. Neutrons: These sub-atomic particles carry no charge and are known as electrically neutral species. These particles are found in the nucleus.
From the above information, the answer to this question is Option B.
Answer: Nonlinear
