If one has a jewish grandmother (from mother's side), but is a muslim/christian jewish because judaism is not allowed as religion in the country, will he/she be eligible to get Israeli citizenship?

0.10 mol of solid sodium hydrogen carbonate and 0.20 mol of solid sodium carbonate are

dissolved in the same beaker of water, transferred to a volumetric flask and made to

250.0 mL. The Ka for HCO3– is 4.7 x 10^–11.

What is the pH of the resulting buffer?

my question is, is a Lewis acid a cation or an anion? pls explain why

Can i know some elements that does not have stable naturally occurring nuclides? And i heard that there are patterns to numbers of neutrons on those elements, any1 can help me explain it?

Is it possible to explain all acid-base reaction with Lewis theory? Pls explain ur reasoning..

I have a reaction

HCN(aq) + H2O(l) -> CN-(aq) + H3O+(aq)

my question is, is the reaction can be categorized as Bronsted-Lowry acid/base reaction or Lewis base/acid reaction? Pls explain why.

I have a question here, we know that

Velocity = dS/dT, where S = distance and T = time

Acceleration = dV/dT, where V= Velocity and T=time

But since velocity = S/T and acceleration =V/T, why can't we substitute acceleration = (S/T)/T = S/T^2?

Can anyone explain how differential works in the physics formulas, like one topic on Hydrostatics, it is said that dF = rho*g*y dy. While i know that F = pressure * area, why can't we use the F = P*A formula?

a. 4.23kJ/mol

b. 104 kJ/mol

c.25.9 kJ/mol

d.180 kJ/mol

Which material below will produce benzoic acid through dichromate oxidation?

a. Benzene

b. t-butylbenzene

c. propylbenzene

d. 1,2-dimethylbenzene

The intermediate formed from attack of an electrophile on benzene in electrophilic aromatic substitution is called..?

1) a resonance stabilised carbocation

2) a nucleophile

3) negatively charged

4) uncharged

5) a carbocation which isnt stabilised by resonance

Which one is correct?
