Write two balanced equations

Chemistry
1 answer:
yanalaym [24]3 years ago
7 0

Answer:

1. NaOH + H₂O → Na⁺ + OH⁻ + H₂O + heat

2. NaOH + HCl → NaCl + H₂O

Explanation:

1. The dissolving of NaOH in water is an exothermic reaction resulting a heat. It also causes the dissociation of NaOH to its ions (Na⁺ and OH⁻).

So, the balanced equation will be NaOH + H₂O → Na⁺ + OH⁻ + H₂O + heat.

2. The reaction between acid and base resulting salt and water. It is considered as a neutralization reaction.

The reaction between HCl and NaOH will give sodium chloride and water and the balanced equation will be NaOH + HCl → NaCl + H₂O.

Answer:

C2H3Br + O2 → CO2 + H2O + HBr

Explanation:

The term balancing of chemical reaction equation has a unique meaning in chemistry. What it actually means is to ensure that the number of atoms of each element on the left hand side of reaction equation becomes equal to the number of atoms of the same element on the right hand side of the reaction equation.

When we look at the equation; C2H3Br + O2 → CO2 + H2O + HBr, the number of atoms of each element on the left and right hand sides of the given equation are not the same hence the equation is unbalanced.

If we look at the equation; 2C2H3Br + 5O2 → 4CO2 + 2H2O + 2HBr, the number of atoms of each element on both sides of the reaction equation are now equal, thus the later equation is the balanced version of the former.

What type of chemical bond involves the sharing of a pair of electrons by two atoms in a molecule.
Over [174]

Answer:

Covalent bond.

Explanation:

There are two kinds of chemical bonds: covalent bonds and ionic bonds.

  • A covalent bond is formed when two atoms share a pair of electrons (two electrons for each bond.)
  • Ions are formed when one atom transfers an electron to another. Ionic bonds refer to the attraction between ions of opposite electric charges.

In this example, since the atoms are sharing atoms, the chemical bond between them would be a covalent bond.
