The reaction between solid aluminum and liquid bromine is exothermic. This reaction creates the product aluminum bromide.
What equation includes the correct formulas and demonstrates conservation of mass?
A Al(s) + Br2(1) - AlBr3(s)
B Al(s) + Br(l) - AlBr(s)
C Al(s) + 3Br(1) - AlBr3(s)
D
2Al(s) + 3Br2(1) - 2AlBr3(s)

correct answer is d)

Explanation:

This answer demonstrates law of conservation of mass because the mass of the products is equal to the mass of reactants with the help of the coefficients which is the process known as balancing. This answer also includes the correct formulas, as Br is a gas so it MUST be written as Br2. hope this helps:)

girl imma just put my comment here because i need a couple point okurrttt
