I know I'm super late to answering this because it's a two week old question, but I'll just answer it any way lol.
The main reason why modern chemistry is considered scientific is because to confirm their results, scientists use the scientific method.
Answer:
Explanation:
Start by writing water as HOH
Ca(OH)2 +CO2 = CaCO3+ HOH
Next pay attention to the CO2 going to CO3
We need an oxygen.
Fortunately that is provided by the (OH)2
Now we have
Ca(OH)2 + CO2 ==> CaCO3 + HOH
and believe it or not, that is balanced as it is
The left side has 1 Ca. So does the right side
The Left side has 1 C. So does the right side.
The left side has 2 H. So does the right side
The left side has 2 oxygens (in Ca(OH2)) + 2 oxygens in CO2
So the equation is balanced.
Answer:I said During the time labeled A when the temperature first starts to increase
Explanation:
I will let you know if it’s right
The study of atomic structure helps us understand more about the way the universe is constructed, how our bodies are made, and the components of life, which we can apply to other sciences in the fields of: health and disease prevention, fuels, product industry etc... It basically helps us to understand how we can make new things and how to utilize the power of the universe.
