Answer is : Fe3O4 + 4CO -> 3Fe + 4CO2
I included my working out.
The highlighted numbers are the numbers which I added after every step in order to get equal numbers on both sides. :)
Answer:
it bubbles up and has a chemical reaction also releases co2
Explanation:
Hope it helps <3
<span>A substance that decreases hand increases ph when it dissociates in water is called a base
</span>
A base is a substance containing (OH)- group (hydroxide group) in its formula. This means that when a base is dissociated in water, hydroxide group (OH)- will be released in the water which leads to the decrease in the concentration of the hydrogen and increases the pH.
On the other hand, an acid contains H+ in its formula. This means that when acid dissociates in water, hydrogen is releases, thus, increasing hydrogen concentration and decreasing pH value.
I would think it is a. A measurement of growth patterns of crystals in space
That is something that is being tested the other ones are just questions and surveys .
