There are 6 hydrogen atoms in every molecule of ethanol
Answer:
I always enjoy a good meal, so I'd say baking is my favorite household chemical reaction.
Explanation:
You are creating an endothermic reaction whenever you bake as the sugars and other molecules are broken apart, fused, and rearranged to make a delicious cake!
I believe it is false i just finished my chemistry class
There are two iron atoms and three oxygen atoms in each molecule of Fe2O3. So that's five atoms per molecule.
One mole of any molecular substance contains <span>6.02×<span>1023</span></span> molecules. Since there are two iron atoms in each of the molecules we're considering, there will be <span><span>(6.02×<span>1023</span>)</span>⋅2=1.204×<span>1024</span></span> iron atoms in a whole mole of them.
But we're considering 0.550 mol, so multiply by 0.550:
<span>n=<span>(0.550</span></span> mol<span>)⋅<span>(3.01×<span>1024</span></span></span> atoms/mol<span>)=6.62×<span>1023</span></span> iron atoms.
A physical change is when somebody smashes a computer screen. It's physical because the looks are changing of the computer. Hope this helps!
