Object one is 5.2 g/cm3
object two is 3.46g/ml
By dividing mass with volume, you will end up with density
Answer:
See detailed reaction equations below
Explanation:
a) Mg(s) +2HBr(aq) ----------------> MgBr2(aq) + H2(g)
b) Ca(ClO3)2(s) ------------> CaCl2(s) + 3O2(g)
c) 3BaBr2(s) +2Na3PO4(aq) ------------> Ba3(PO4)2(s) + 6NaBr(aq)
d) 3AgNO3(aq) + AlI3(aq) --------------> 3AgI(s) + Al(NO3)3(aq)
Balancing reaction equations involves taking valencies and number of atoms of each element on the reactants and products side into consideration respectively.
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>
