Answer:
Covalent bonding is usually exhibited when the electronegativity difference between two atoms is 1.1
Explanation:
The electronegativity difference identifies the type of bonding (i.e. covalent bonding and ionic bonding) between two atoms.
Covalent Bonding is the type of chemical bonding that form by the sharing of electron pairs between two atoms.
Ionic Bonding is the type of chemical bonding that form by the complete valence electrons transfer between two atoms.
Electronegativity is the force with which an atom attract shared pair of electrons towards itself.
The formation of covalent bond occurs when the electronegativity difference (ΔEN) between two atoms, sharing electrons with each other, is less than 1.7 which means that the atoms, having covalent bonding, do not have strength to transfer electrons towards themselves. If the electronegativity is greater than 1.7 then ionic bonding exist between two atoms because they have enough strength to transfer electrons towards themselves.
A. The kinetic energy of the food particles increased, causing the food temperature to rise.
B. The thermal energy of the food increased
Explanation:
The grilling of the meat increased the thermal energy which cause the kinetic energy of the food particles to increase thereby causing the temperature of the food to rise.
Heat is a form of energy known as thermal energy. It results from the difference in temperature between two bodies.
When a body is heated, the particles of the medium if solid as in the case of the meat begins to vibrate about their fixed point.
Temperature is directly proportional the average kinetic energy of a particle and so the particles gain more kinetic energy.

Environmental conditions
Explanation:
Traits that are due to environmental conditions are considered to be acquired traits. This kind of trait are not coded in the DNA and passed down as inherited traits.
- A larger body muscle due to regular exercise and fitness training is an acquired trait.
- Skin color most times are inherited.
- Acquired traits are typically conditioned due to the environment an organism finds itself.
- These traits cannot be passed down.

The equilibria showing how the acetate buffer adjusts to addition of a small amount of NaOH is:
- CH3COOH(aq) + H2O(1) → H30+ (aq) + CH3COO (aq)
<h3>What is a buffer?</h3>
A buffer is a solution which resists changes to its pH when small amounts of strong base or acid is added to it.
Buffers are made from solutions of weak acids and their salts or weak bases and their salts.
The equilibria showing how a buffer made from acetic acid and sodium acetate (NaCH3COO) adjusts to addition of a small amount of NaOH is as follows:
- CH3COOH(aq) + H2O(1) → H30+ (aq) + CH3COO (aq)
Addition of NaOH, a strong base will neutralize the hydronium ion, causing the acetic acid ionization equilibrium to shift to the right to produce more of the acetate ion, the conjugate base.
