Answer:
mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas
Explanation:
iquid 1 reacts with Liquid 2, producing a solid and a gas. Using this scenario, which supports the law of conservation
of mass?
EEEE
O mass of Liquid 1 + mass of solid = mass of Liquid 2 + mass of gas
O mass of Liquid 1 - mass of solid = mass of Liquid 2-mass of gas
O mass of Liquid 1 - mass of Liquid 2 = mass of solid + mass of gas
O
based on the law of the conservation of matter, the sum of the masses of the reactants must equal the sum of the masses of the products
so the correct answer is
mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas
Answer:
u didn't give us the multiple hoice answer
Explanation:
Answer: The volume of the gold is 
The mass of gold is 19.3 g
The density of gold is 
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of gold = 19.3 grams
To calculate the volume of cube, we use the equation:
where,
V = volume of cube
a = edge of cube
Volume of gold = 
Putting values in above equation, we get:
Putting in the values we get:
Thus density of gold will be
