C. The moving ball from point A to point B
Hello, this question is incomplete. The complete question would be:
"Write the balanced chemical equation for the following reaction.
Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water"
Answer:
Fe2O3 + 3 H2 = 2 Fe + 3 H2O
Explanation:
In a chemical reaction, the structure of atoms as chemical elements is unchanged. Atoms in one element do not become atoms in another element. There is also no loss or creation of new atoms. The number of atoms of the reagents must be equal to the number of atoms of the products. When this happens, we say that the chemical equation is balanced.
For this reason, we can state that the balanced chemical reaction where solid iron (III) oxide reacts with hydrogen gas to form solid iron and liquid water would be:
<em>Fe2O3 + 3 H2 = 2 Fe + 3 H2O
</em>
C — all others endanger you.
This is an incomplete question, here is a complete question.
Determine the specific heat of a material if a 35 g sample absorbed 96 J as it was heated from 293 K to 313 K.
Answer : The specific heat of a material is, 0.137 J/g.K
Explanation :
Formula used to calculate the specific heat of a material is:
where,
q = heat absorbed = 96 J
m = mass of sample = 35 g
c = specific heat capacity of material = ?
= initial temperature = 293 K
= final temperature = 313 K
Now put all the given values in the above formula, we get:
Therefore, the specific heat of a material is, 0.137 J/g.K
Answer:
Polar
Explanation:
Methanol is not electrostatic
It's not metallic as it has no metals in it
It's not ionic as coordinate bonding is made.
It's polar as a lone pair is present over OH-
