Answer:

Explanation:

Mass of compound A  = 25g

Mass of compound B = 40g

Mass of final mixture = 55g

What happens to the missing mass?

According to the law of conservation of mass, in chemical reaction, matter is transformed from one form to another but cannot be created nor destroyed.

We expect the final mass of the mixture and that of the reacting compounds to be the same but the opposite is the case.

There is a mass loss which typifies most chemical reaction.

The reason for this is that some of the masses must have been lost by the production of gaseous species which are unaccounted for.

The missing mass:

  Total mass expected  = mass of A + mass of B = 25 + 40 = 65g

Missing mass = expected mass - mass of final mixture = 65 - 55 = 10g

NikAS [45]
<span>renewable resources are used primarily to produce electricity include wind and hydro-electric power. they require large mechanical structures e.g. wind turbine and water dam in order to generate electric energy. Therefore they are not appropriate for home use.

</span><span>renewable resources are readily used as heat sources for homes include solar-water heating system in which water is heated by sunlight and circulated around the house. Wood burning for heat can also be considered a renewable resource as long as the wood comes from a sustainable logging cycle.</span>
