When the equation: __al2(so4)3 + __zncl2 → __alcl3 + __znso4 is correctly balanced using the smallest whole number coefficients, the sum of the coefficients is?

the sum of the coefficients is 9

Explanation:

1Al(SO4)3 + 3ZnCl2 —> 2AlCl3 + 3ZnSO4

The coefficients are 1, 3, 2, 3.

Sum of the coefficients = 1 + 3+ 2+ 3 = 9

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

it is a good conductor
