It starts with a cation and ends with a nonmetal anion. To recap, cations are your positively charged elements and anions are negatively change and usually with the ending “ide”. For example, potassium a metal and chlorine a nonmetal (KCl) would form the word potassium chloride.

A) Mention any two properties of an ideal fuel. (b) What is meant by calorific value? (c) 2kg of a fuel produces 48,000 KJ of he
Brilliant_brown [7]

Answer and explanation:

A) An ideal fuel must:

- easy to transport and storage.

- have a high calorific value.

B) The <em>calorific value</em> for a fuel is the amount of heat - measured in Joules- which is produced during the complete combustion of the fuel. It is expressed in Joules per Kg of fuel (J/kg).

C) From the data:

mass of fuel = 2 kg

heat produced = 48,000 KJ

We calculate the calorific value by dividing the heat produced by the mass of fuel, as follows:

calorific value = heat produced/mass of fuel = (48,000 KJ)/(2 kg)= 24,000 kJ/kg

Since 1 KJ= 1000 J, we can express the calorific value in J/kg as follows:

24,000 kJ/kg x 1000 J/1 kJ = 2.4 x 10⁷ J/kg

(N2 &amp; O2 &amp; Ar &amp; CO2...) <br> an element compound or mixture?
ololo11 [35]

Answer: Mixture

Explanation:

Element is a pure substance which is composed of atoms of similar elements.

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.

Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air which conatins a mixture of N_2, O_2 , Ar and CO_2

Classify each of these reactions pb(no3)2+nicl2=pbcl2+ni(no3)2
maxonik [38]

The reaction Pb(NO3)2(aq) + NiCl2(aq)---------> PbCl2(s) + Ni(NO3)2(aq) is a precipitation reaction.

A chemical reaction is said to occur when two or more substances are combined to produce new substances. Chemical reactions are classified based on the kind of change taking place in the reaction.

In the reaction;

Pb(NO3)2(aq) + NiCl2(aq)---------> PbCl2(s) + Ni(NO3)2(aq)

We can see that a solid is formed when lead II nitrate reacts with nickel II chloride. This is a precipitation reaction.
