Answer: 1. The ratio of the reactant aluminum to the product aluminum sulphate is 2:1

2. Option D. 1,3,2,2

Explanation: 1. From the balanced equation:

2Al + 3H2SO4 -> Al2(SO4)3 + 3H2

2moles of Al produced 1mole of Al2(SO4)3. Therefore, the ratio will be 2:1

2. C2H4 + 3O2 ---> 2CO2 + 2H2O from the equation, the coefficients are 1,3,2,2

A student finds a piece of metal that she thinks is aluminum. She finds the volume to be 245 cm^3 and the mass to be 612 grams.

natta225 [31]

Answer:

Density = 2.5 g/cm³ , The metal is aluminium.

Explanation:

Density is defined as the ratio of the mass and the volume

Thus,

$Density=\frac {Mass}{Volume}$

Given that:

Mass = 612 grams

Volume = 245 cm³

Thus, Density is:

$Density=\frac {612}{245}\ g/cm^3$

Density = 2.5 g/cm³

Metals are shiny with high density.

The density of aluminium falls is approx 2.6 g/cm³ and not other metal's density falls in this range.

The metal is aluminium.
