Cho 80g dung dịch NaOH 20% tác dụng vừa đủ với 200g dung dịch H2SO4 tạo ra muối trung hòa a. Viết phương trình phản ứng

b. Tính nồng độ phan trăm dung dịch H2SO4 đã dùng

c. Tính nồng độ phần trăm các chất trong dung dịch sau phản ứng.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

gas

explanation:

smoke is the matter of a gas
