Answer:
Explanation:
Hello,
In this case, given that one mole of glucose, contains six moles of oxygen (subscript), we can also see it contains twelve moles of hydrogen (subscript), therefore, the moles of hydrogen in the sample are computed by:
Best regards.
Answer:
reason is Heat is involved, the reaction is exothermic and therefore heat is lost to the surrounding
Answer:
option b : O₉S₁₀
Explanation:
There are some points to name a covalent compound, according to that
number of atoms numbered as
**mono for one, di - for two tri for three and so on.
the name of the atom as
**carbon as carbide, sulfur as sulfide, oxygen as oxide, foulrine as flouro etc.
So,
Formula of Nonoxide decasulfide
Now Naming of the Chemical compound
Following are the explanations of terms
- Prefix nono is used for number ''9'' denoting to the number of atom
- Oxide used for oxygen
- deca is use for number ''10'' denoting to the number of atom
- Sulfide is used for Sulfur in a compound
So keeping the above points in mind
The right answer is
Option b : O₉S₁₀
Answer:
5.97 mol
Explanation:
To find the number of moles when given the mass of a substance, we divide the mass of the sample by its molar mass.
so, we get,
nN203 = 454 g / 76.01 g /mol
= 5.97 mol
