106.4 is going to be your answer
It is True because in the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families.
Answer: 14.7 atm
Explanation:
Using the ideal gas law also called the general gas equation ;
PV = nRT
Where,
P = pressure
V = Volume
n = amount of substance
R = ideal gas constant
T = temperature
For the He sample;
V = 2.5 L
n = 1.5 mol
R = 8.314 J/mol/K or 0.0821 L atm/mol/K
T =?
T = PV/nR
T = 14.7*2.5/(1.5*0.0821)
T = 298.42K
For the H2 sample, since both are under the same condition :
P = nRT/V
P = (1.5*0.0821*298.42) ÷ 2.5
P = 14.7 atm.
The equation for the production of Ammonia is:
N₂ + H₂ → NH₃
N₂ + H₂ (LeftHandSide of equation) : 2 Nitrogen atoms; 2 Hydrogen atoms
NH₃ (RightHandSide of equation): 1 Nitrogen Atom; 3 Hydrogen atoms
To balance the equation you must place in front of each compound/molecule/element that makes the amount of atom of each element equal on both sides of the equation.
N₂ + 3H₂ → 2NH₃
LHS RHS
Nitrogen 2 2
Hydrogen 6 6
So essentially the set of coefficients you use to balance the equation are 1 for N₂, 3 for H₂ and 2 for NH₃.
<u>Answer:</u> The products of the given chemical equation are 
<u>Explanation:</u>
Protonation equation is defined as the equation in which protons get added in the substance.
The chemical equation for the protonation of carbonate ion in the presence of water follows:
By Stoichiometry of the reaction:
1 mole of carbonate ion reacts with 1 mole of water to produce 1 mole of hydrogen carbonate ion and 1 mole of hydroxide ion
Hence, the products of the given chemical equation are
