CnH2n since the equivalent unsaturation is equal with 1
Answer:
False
Explanation:
The relationship between energy and amplitude can be written as eαa^2
This means that the energy of a wave is directly proportional to the square of the amplitude.
Answer is: molarity of solution is 0,5 mol/dm³.
m(NaOH) = 10,0 g.
V(NaOH) = 500 ml = 0,5 dm³.
c(NaOH) = ?
n(NaOH) = m(NaOH) ÷ M(NaOH).
n(NaOH) = 10,0 g ÷ 40 g/mol.
n(NaOH) = 0,25 mol.
c(NaOH) = n(NaOH) ÷ V(NaOH).
c(NaOH) = 0,25 mol ÷ 0,5 dm³.
c(NaOH) = 0,5 mol/dm³.
Cookware manufacturers who make pans out of steel only because if C-8 is discontinued then people would have no choice but to buy steel pans. The steel pan manufacturers would in return receive a lot of money
POH+pH=14
pH=14-pOH=14-3.53=10.47
pH=-log[H⁺]
[H⁺]=10^(-pH)
[H⁺]=10^(-10.47)=3.4*10(^-11)
