What is the product of 3fe + 4h20 > fe3o4+4h2
1 answer:
Ferrosoferric oxide and hydrogen gas are the products of this reaction.
<h3><u>Explanation:</u></h3>Iron is the metallic element with the atomic number 26. It has a valency of both 2 and 3 which forms two types of oxide - ferrous oxide and ferric oxide.
Iron reacts with water with a metal and acid reaction, which forms both the iron oxide and evolves hydrogen gas. The hydrogen gas escapes the system and the mixture of iron oxide is left over in the system. The mixture is denoted by the formula and is called ferrosoferric oxide.
This reaction is reversible and is reversed if hydrogen gas is passed over heated ferric oxide in increased pressure.

Answer:
Mass of oxygen in glucose = 29.3g
Explanation:
Mass of glucose given is 55grams.
We are to find the mass of oxygen in this compound.
In the compound we have 6 atoms of oxygen.
Solution
To find the mass of oxygen in glucose, we calculate the formula mass of glucose. We now divide the formula mass of the oxygen atom with that of the glucose and multiply by the given mass to find the unkown mass.
Atomic mass of C = 12g
H = 1g
O = 16g
Formula mass of C₆H₁₂O₆ = {(12x6) + (1x12) + (16x6)} = 180
Mass of O in glucose = x 55
= x 55
= 0.53 x 55
Mass of oxygen in glucose = 29.3g
