Answer:
15 ml
Explanation:
Volume = mass / density.
So our answer is 15 / 3 = 15 mL
Answer: The value of equilibrium constant for new reaction is
Explanation:
The given chemical equation follows:
The equilibrium constant for the above equation is 
We need to calculate the equilibrium constant for the equation of 3 times of the above chemical equation, which is:
The equilibrium constant for this reaction will be the cube of the initial reaction.
If the equation is multiplied by a factor of '3', the equilibrium constant of the new reaction will be the cube of the equilibrium constant of initial reaction.
The value of equilibrium constant for reverse reaction is:
Hence, the value of equilibrium constant for new reaction is
Answer: Total Number of Atoms is Nine.
We have 3 atoms of (C)carbon, 5 atoms of (H)hydrogen and 2 atoms of (O)oxygen. So total is 3+5+2=10
It means there are 10 atoms in the compound and from the formula we come to know that there are 2 molecules . Therefore 2×10=20 atoms.
C3 means there are 3 atoms of carbon in one molecule
3C means just 3 atoms of carbon
3C3 means there are 3 molecules of carbon with 3 carbon atoms in each molecule. So total atoms is 9.
Hope I helped!
Answer:
Chemical change
Explanation:
Matter changes into a new substance by changing into a chemical change. In a chemical change, the substance cannot be changed back to its previous state and a new substance is formed.
