Use the following periodic table to you. what is the best name for nabr2? monosodium bromide sodium bibromide sodium dibromide sodium bromide

I think there's a problem with the question. I think you meant NaBr. 2Na + Br2 -> 2NaBr The name is Sodium Bromide.

Dis a correct answer

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
