Strontium metal reacts with aluminum chlorate to produce strontium
Fudgin [204]

Answer: single replacement reaction, 3Sr+2Al(ClO_3)_3\rightarrow 3Sr(ClO_3)_2+2Al

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

A general single displacement reaction can be represented as :

XY+Z\rightarrow XZ+Y

As strontium metal is added to aluminum chlorate , strontium being more reactive than aluminium, displaces aluminium atom its salt solution and lead to formation of strontium  chlorate and aluminum metal.

3Sr+2Al(ClO_3)_3\rightarrow 3Sr(ClO_3)_2+2Al

Please help me!! A sample of an unknown metal has a mass of 22.4g. A graduated cylinder contains 3.2 ml of water. After the meta
Firdavs [7]

Answer:

d = 14.9 g/mL

Explanation:

Given data:

Mass of metal = 22.4 g

Volume of eater = 3.2 mL

Volume of water + metal = 4.7 mL

Density of metal = ?

Solution:

Volume of metal:

Volume of metal = volume of water+ metal - volume of water

Volume of metal = 4.7 mL - 3.2 mL

Volume of metal = 1.5 mL

Density of metal:

d = m/v

d = 22.4 g/ 1.5 mL

d = 14.9 g/mL

kow [346]

Answer:

Explanation:

The relative atomic mass of an element is a weighted average of the masses of the atoms of the isotopes - because if there is much more of one isotope then that will influence the average mass much more than the less abundant isotope will.
