Answer:
The correct option is FALSE
Explanation:
Mole ratio is the ratio of the number of moles of two compounds in a balanced chemical reaction. Number of moles of a compound in a chemical reaction is the number written before the compound.
For example, the mole ratio of Iron (Fe) and water (H₂O) in the equation below is 3:4
3Fe + 4H₂O ⇒ Fe₃O₄ + 4H₂
Thus, mole ratio does not compare subscripts of compounds.
Answer:
1.14atm
Explanation:
Given parameters:
V1 = 250cm³ ;
1000cm³ = 1dm³; so this is 0.25dm³
P1 = 760torr
760torr = 1atm
V2 = 220cm³ ; 0.22dm³
Unknown:
New pressure = ?
Solution:
To solve this problem, we apply Boyle's law and we use the expression below:
P1 V1 = P2V2
The unknown is P2;
1 x 0.25 = P2 x 0.22
P2 = 1.14atm
Answer:
by moving between defined energy levels
