Nata [24]

Answer:

1. How do metals and non-metals react with acids?

Ans : Non metals does not react with acids while metals react with acids and produce hydrogen gas that burns with a 'pop'sound.

2. Write and explain the chemical equation for the reaction of magnesium with sulphuric acid and aluminium with hydrochloric acid.

Magnesium + sulphuric acid = Hydrogen + salt

Mg(s) + H2SO4 (aq) MgSO 4(aq) +H2 (g)

Aluminium + Hydrochloric acid = Hydrogen + Aluminium chloride

2Al(s)+6HCl(aq)→2AlCl3(aq)+3H2(g)

Sodium metal reacts with water to produce hydrogen gas and sodium hydroxide according to the chemical equation shown below.
UNO [17]

<u>Answer:</u> The enthalpy change of the reaction is -361.6 kJ

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Moles of sodium = 0.025 moles

Molar mass of sodium = 23 g/mol

Putting values in above equation, we get:

0.025mol=\frac{\text{Mass of sodium}}{23g/mol}\\\\\text{Mass of sodium}=(0.025mol\times 23g/mol)=0.575g

We are given:

Mass of water = 100.00 g

Mass of sodium = 0.575 g

Mass of solution = 100.00 + 0.575 = 100.575 g

To calculate the amount of heat absorbed, we use the equation:

q=m\times C\times \Delta T

where,

q = amount of heat absorbed = ?

m = mass of solution = 100.575 g

C = specific heat capacity of solution = 4.18 J/g°C

\Delta T = change in temperature = (T_2-T_1)=(35.75-25.00)=10.75^oC

Putting all the values in above equation, we get:

q=100.575g\times 4.18J/g^oC\times 10.75^oC=4519.34J=4.52kJ

When heat is absorbed by the solution, this means that heat is getting released by the reaction.

<u>Sign convention of heat:</u>

When heat is absorbed, the sign of heat is taken to be positive and when heat is released, the sign of heat is taken to be negative.

For the given chemical reaction:

2Na(s)+2H_2O(l)\rightarrow NaOH(aq.)+H_2(g)

When 0.025 moles of sodium is reacted, the heat released by the reaction is 4.52 kJ

So, when 2 moles of sodium will react, the heat released by the reaction will be = \frac{4.52}{0.025}\times 2=361.6kJ

Hence, the enthalpy change of the reaction is -361.6 kJ

What elements would likely form an ionic bond?
Nutka1998 [239]

Answer:

b. Mg & Cl

a. transferred

46

Explanation:

Ionic bonds form between metals and non-metals when electrons are transferred from one specie to another.

  • The electrostatic attraction from the resulting ions forms the ionic bonds.
  • A metal is electropositive and will readily donate electrons
  • A non-metal is electronegative and will accept electrons.
  • This creates two oppositely charge ions that attracts by means of ionic bonding.

Since Mg and Cl are the only metal - non-metal pair, and ionic bond will form between them.

2.

  In the specie;

          ₄₇Ag¹⁺

47 is the atomic number of the element Ag.

The atomic number is the number of protons in an atom. For a specie in neutral state, the number of protons and electrons are the same.

  • When an atom loses electron, it becomes positively charged.
  • Here Ag has lost one electron and then, the number of electrons becomes 46.
  • The number of protons is still 47
