The name carbohydrate indicate chemical composition of sugars, as carb means carbon and hydrate means hydrogen and oxygen.
Carbohydrate indicates the presence of carbon, hydrogen and oxygen of which sugar molecule is made up of.
Carbohydrate can be defined as naturally occuring molecules that is made of carbon, hydrogen and oxygen.
An acid is deemed strong if it can readily or easy "donate" a proton (H+) to the other ions in the solutions. Also, to donate or lose the proton or H+, the acid must dissociate (split into ions) in the solution. The more it can readily dissociate, the stronger the acid is.
Answer:
CaCO3 -> CaO + CO2
Explanation:
Woahhhh, did you balance it yourself just then?
Answer:
2H₂ + O₂ —> 2H₂O
The coefficients are: 2, 1, 2
Explanation:
__ H₂ + __ O₂ —> __ H₂O
The above equation can be balance as illustrated below:
H₂ + O₂ —> H₂O
There are 2 atoms of O on the left side and 1 atom on the right side. It can be balance by writing 2 before H₂O as shown below:
H₂ + O₂ —> 2H₂O
There are 2 atoms of H on the left side and 4 atoms on the right side. It can be balance by writing 2 before H₂ as shown below:
2H₂ + O₂ —> 2H₂O
Now, the equation is balanced and the coefficients are: 2, 1, 2
