<em>Brainliest Please?</em>
The charge is 2- (2 minus). This is because sodium ion has a charge of 1+ and 2 of them are there in the compound. Thus the charge is 2-
Answer:
when cell is exposed to radiation we get brain tumour or cancer.
C - nucleus, cytoplasm, plasma membrane.
M(NaOH)=15 g
v=600 ml=0.6 l
n(NaOH)=m(NaOH)/M(NaOH)
C=n(NaOH)/v=m(NaOH)/[M(NaOH)v]
C=15g/[40g/mol*0.6 l]=0.625 mol/l
0.625M
[H⁺]=7.5*10⁻²
pOH=14-pH=14+lg[H⁺]
pOH=14+lg(7.5*10⁻²)=14-1.125=12.875
