N=24/12
n=2
where n= no. of moles
Because the equator is closer to the sun, the sun rays hit the earth’s surface which causes the temperature to be warm at a higher angle at the equator,
It means it depends on how much of the chemical you have. For ex. if 1 drop of snake venom might not kill you, but 20 drop could definitely kill you. Hope this helps!
Answer:
coefficient 3 is needed t with water molecule to balance the equation.
Explanation:
Chemical equation:
Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Balanced chemical equation:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
The equation is balanced. There are two iron three sulfate six hydrogen and three oxygen atoms are present on both side of equation.
The given equation completely follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Coefficient with reactant and product:
Fe₂O₃ 1
H₂SO₄ 3
Fe₂(SO₄)₃ 1
H₂O 3
So coefficient 3 is needed t with water molecule to balance the equation.
<em>Answer:</em>
- The atom consist of three parts, proton, neutron and electrons. The electrons determine that i will combine or beak from other substances.
<em>Explanation:</em>
The atom consist of three parts which are following
The proton and neutron form nucleus of an atom. It is present at center of an atom. They have positive charges, while electrons remained outside the nucleus in particular energy levels or shell around the nucleus.
During combination or breaking of substances ,only arrangements of electrons take place. The valence shell electrons decide whether they have to combine or not, while nucleus remained unchanged during any reactions.
