Four Consecutive terms are written as a-3, a-1, a+1,a+3. So
Sum of Terms : 4a=28
a=7
So the terms are 4,6,8,10
Verification : 4^2+6^2+8^2+10^2
= 216
I would divided it to get the anwser and then moloeces
Explanation:
Divide
The equilibrium constant (K) : 11.85
<h3>Further explanation</h3>
Given
Reaction
N₂(g) + 3H₂(g) ⇒ 2NH₃(g)
Required
K(equilibrium constant)
Solution
The equilibrium constant (K) is the value of the concentration product in the equilibrium
The equilibrium constant based on concentration (K) in a reaction
pA + qB -----> mC + nD
For the reaction above :
Answer:
B
Explanation:
You start from the highest energy level to the lowest. The arrangement is: 1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s<5f<6d<7p. Each box in the configuration can hold up to 2 electrons. This rule tells you to fill all boxes of one particular subshell with 1 electron first, before double occupying them.
Answer:
Hydrogen and hydrogen
Explanation:
A nonpolar covalent bond is formed when there is little or no electro negativity difference between the two bonding atoms in a covalent bond. This implies that the shared electron of the covalent bond is placed at an equidistant position from the nuclei of the two bonding atoms.
A bond between hydrogen and hydrogen is a homonuclear covalent bond, there is no electro negativity difference between the bonding atoms hence the covalent bond formed will be nonpolar.
