Which of the following an inorganic compound?CH3(CH2)3CH3 pentane
C6H12O6 glucose
C4H10 butane
H2O water molecule
Answers
Pentane has 5 carbon atoms with surrounding hydrogens.
glucose is a chain of 6 carbon atoms
butane is similar to pentane
water has no carbon atoms, and the central atom is oxygen ---> therefore it is inorganic!

Answer:
Independent Variable = Years
Dependent Variable = Number of Mobiles phone owners
Explanation:
Independent variables are plotted on x-axis and the dependent variables are plotted on y-axis.
In given graph the "Years" belong to x-axis hence, years are the independent variables.
Also, "Number of Mobile phones owners" belong to y-axis hence, this number is the dependent variable.

In chemistry we like the number of atoms or molecules in moles.
If one mole is equal to 6.02*10^23 atoms and you have 9.00 *10^23 atoms then how many moles do you have?
Answers
Answer;
= 1.495 moles
Explanation;
-One mole contains 6.02 ×10^23 particles
Therefore;
1 mole = 6.02 ×10^23 atoms
Thus; 9.00 ×10^23 atoms will have;
= 9.00 ×10^23 atoms / 6.02 ×10^23 atoms
= 1.495 moles

Explanation:
Before doing any calculations, it's worth noting that atoms do not contain moles, it's the other way around.
A mole is simply a collection of atoms. More specifically, you need to have exactly
