the process of changing one form of energy into another
Its overall charge is zero because it has 2 electrons 2 protons and 2 neutrons also it is zerovalent in nature as it is an inert gas
Tree structure it would show how it holds together
Answer:
1.389 moles
Explanation:
We are given that
Given mass of ammonium=25.0 g
We have to find the number of moles in 25.0g of ammonium.
The chemical formula of ammonium 
Molar mass of N=14, Molar mass of H=1
Molar mass of ammonium (NH4+)=14+4(4)=18 g/mol
We know that
Number of moles=Given mass/Molar mass
Using the formula
Number of moles of ammonium=
moles
Number of moles of ammonium=1.389 moles
Hence, the number of moles in 25.0g of ammonium=1.389 moles
Answer:
38.4 atm.
Explanation:
- We can use the general law of ideal gas:<em> PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have different values of P and V:
<em>(P₁V₁) = (P₂V₂).</em>
P₁ = 3.0 atm, V₁ = 3200 L,
P₂ = ??? atm, V₂ = 250.0 L.
∴ P₂ = (P₁V₁)/(V₂) = (3.0 atm)(3200 L)/(250.0 L) = 38.4 atm.
