PLZ HELP will give brainliest to best answer if I can

You are testing a solution for pH and find it to be 8.31 on the pH scale. Is this solution acidic, basic or neutral. Explain.

it's neutral

Explanation:

on the ph scale 7-8 is in the middle and everything after 8 is acidic and everything under 7 is basic. (you can look up a picture of a ph scale you will see what I mean)

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

the answer is 303.15 or 303
