what is p³×p simplify
Answer:
The answer is p⁴.
Explanation:
You have to apply Indices Law :
[tex] {a}^{m} \times {a}^{n} ⇒ {a}^{m + n} [/tex]
For this question :
[tex] {p}^{3} \times {p}^{1} [/tex]
[tex] = {p}^{(3 + 1)} [/tex]
[tex] = {p}^{4} [/tex]

Explanation:
As an electron in an atom moves from a higher energy state to a lower energy state, the atom
1 becomes a negative ion
2 becomes a positive ion
3 releases energy
4 absorbs energy
Answer:
3 releases energy
Explanation:
An electron in an energy level has a definite amount of energy associated with it at that level.
Electrons can undergo transitions from one level to another. However, when the electron changes its state, it must absorb or emit the exact amount of energy which will bring it from the initial to the final state.
When the electron is excited, it moves from the ground state to an excited state, it must absorb energy. On returning from an excited state to a lower level or the ground state, energy is emitted, giving rise to a line in the spectrum.
Answer: 3 because it releases energy
What is the cost in dollars for the nails used to build a fence 80 meters long if it requires 30 nails per meter? There are 40 nails per box at a cost of 75 cents per box
Answer:
4500 cent
Explanation:
From the question, we were told that
a fence 80 meters long requires 30 nails per meter.
1 metre fence = 30 nails
Then 80 meters long= ( 30 × 80)
= 2400 nails
Which means a fence 80 meters long will require 2400 nails in total.
We need to find the cost in dollars for the nails to build a fence 80 meters long.
We know that 40 nails per box will cost 75 cents per box.
(2400 nails/40 nail per box)= 60 box
Then 60 box will be needed to complete the fence.
the cost in dollars for the nails to build a fence 80 meters long= (60 box × 75 cent per box)=4500 cent
What is the balanced equation for the reaction of a solution of sodium sulfate is mixed with strontium chloride?
Select one:
a.Na2SO4(aq) + SrCl2(aq) = 2 NaCl(aq) + SrSO4(s)
b.Na2SO4(aq) + SrCl2(aq) = NaCl(s) + SrSO4(aq)
c.NaSO4(aq) + SrCl(aq) = NaCl(aq) + SrSO4(aq)
d.NaSO4(aq) + SrCl(aq) = NaCl(aq) + Sr2SO4(aq)
Answer:A
Explanation: reactants: Na2SO4 and SrCl2
Products: NaCl and SrSO4

Explanation:
How many molecules are in 200.0 g of ammonium sulfide
Answer: 1.51355 mol.
Explanation:
What forces typically hold nonmetal atoms together within a molecule?
A. Metallic bonds
B. Covalent bonds
C lonic attractions
D Intermolecular forces
Answer:
B - Covalent bonds
Explanation:
Covalent bonds are a class of chemical bonds where valence electrons are shared between two atoms, typically two nonmetals. The formation of a covalent bond allows the nonmetals to obey the octet rule and thus become more stable.
