Answer:
See explanation below
Explanation:
You are not putting the equation to balance. I found a question which is pretty the same as this one and put the following reaction:
H₂ + O₂ ------> H₂O
If you have a different equation please post again the question.
According to the above reaction, we can say that it's not balanced.
The reason is because in the reactants we have 2 atoms of hydrogen and oxygen, but in the products, we only have 1 atom of oxygen. so both sides do not have the same number of atoms.
To balance, we need to put a number in the product or reactant as coefficient in order to balance the whole reaction. In this case, as Oxygen is unbalanced, I will put a 2 in the products to balance the oxygen:
H₂ + O₂ ------> 2H₂O
But putting this 2 will unbalance the hydrogen in the products. We now have 4 atoms of hydrogen. What should we do now?, yes, we put a 2 in the reactants to balance the hydrogen, and then, the whole equation is balanced.
2H₂ + O₂ ------> 2H₂O
Hope this helps
The correct matches are as follows:
1. Big Bang theory: Theory that suggests the origin of the universe started with an explosion and expansion of a very hot, dense, compact fireball.
2. Steady state theory: Theory about the origin of the universe that suggest that the universe has and will continue to be at a steady continuous state.
3. Oscillatory universe theory: Theory about the origin of the universe that suggests the universe is a never ending cycle of expansion and contraction.
4. Nebular theory: Theory about the origin of the solar system that suggest our sun and planet formed from a cloud of dust and gas.
5. Inflation theory: Theory that upholds the big bang theory but suggest there was an extremely rapid expansion or inflation milliseconds after the big bang.
6. Condensation theory: Theory about the origin of the solar system that agree with the nebular theory but stresses the importance of interstellar dust in planet formation.
Answer:
last choice
Explanation:
oxidation and reduction can be defined in terms of adding or removing oxygen to a compound
oxidation is gaining oxygen
reduction is to loss oxygen
