The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.
3) CH₃-COOH + NH₃ → CH₃-COO⁻NH₄⁺
4) 2 FeCl₃ + 3 Ag₂SO₃ → Fe₂(SO₃)₃ + 6 AgCl
5) 2 Al + 3 NiCl₂ → 2 AlCl₃ + 3 Ni
6) 4 LiCl + Pb(NO₂)₄ → 4 LiNO₂ + PbCl₄
7) 3 H₂SO₄ + 2 Al(OH)₃ → Al₂(SO₄)₃ + 6 H₂O
8) Cd(NO₃)₂ + Na₂S → CdS + 2 NaNO₃
9) Cr₂(SO₄)₃ + 3 (NH₄)₂CO₃ → Cr₂(CO₃)₃ + 3 (NH₄)₂SO₄
Answer:
2N2 + O2 ⇒ 2N2O
Explanation:
Since I cannot see the product's of the second chemical equation I will only solve the first one.
In order to balance a chemical equation you need to make sure that the atoms on both sides are equal.
In this case we have...
N2 + O2 = N2O
N = 2
O = 2
N = 2
O = 2
Change the coefficient:
N2O = 2N20
2 × 2 = 4
1 × 2 = 2
2N2 + O2 ⇒ 2N2O
Hope this helps.
Answer:
0.5mol/L
Explanation:
First, let us calculate the number of mole NaOH = 23 + 16 + 1 = 40g/mol
Mass of NaOH from the question = 30g
Number of mole = Mass /Molar Mass
Number of mole = 30/40 = 0.75mol
Volume = 1.5L
Active mass = mole/Volume
Active mass = 0.75mol/1.5L
Active mass = 0.5mol/L
Answer:
The properties of a solid are that they form at a low temperature, particles have long range order meaning that the particles are fixed in place, the particles have a defined shape and volume, the solid particles are a low-energy state of matter, and solid particles are dense and incompressible. But on the other hand plasma particles form at high temperatures, plasma particles have short range order meaning that the plasma particles have little interaction, plasma particles fill all available space meaning plasma particles have no fixed shape or volume, plasma particles are the highest energy-state of matter, plasma particles are highly compressible, and plasma particles conduct electricity extremely well.
