Explanation

An exothermic reaction is a chemical reaction that releases energy in the form of light or heat

it is the opposite of an endothermic reaction

expressed in a chemical equation:

reactants --> protect + energy

exothermic reaction "Exo" means the release and "thermic" means heat

Explanation

HbA1c reflects long-term blood glucose levels.

Biguanides, such as Metformin, are commonly used to treat type 2 diabetes to help decrease HbA1c.

HbA1c lowering effect

1. Metformin: Typically reduces HbA1c by 1-2% (11-22 mmol/mol).

2. Sulfonylureas: May reduce HbA1c by 0.5-1.5% (5.5-16.5 mmol/mol).

3. Acarbose: Typically reduces HbA1c by 0.5-1% (5.5-11 mmol/mol).

Explanation

 in every instant of time, the wavelength associated with a freely falling body decreases.

This is because the de Broglie wavelength 

λ of a particle is inversely proportional to its momentum:

(𝜆=ℎ/𝑝 ).

where:

• $h$ is Planck's constant,
• $p$ is the momentum of the particle.

Explanation

To find the total number of radians through which a point on a wheel has rotated, we can use the fact that one complete revolution corresponds to 2π radians.

For 3 complete revolutions, the total radians can be calculated as follows:

Total radians=Number of revolutions×2π

Total radians=3×2π=6π

Explanation

Kaolin, or 'china clay' as it is commonly called, is a hydrated aluminum silicate crystalline mineral

Kaolinite is a clay mineral, with the chemical composition: Al2Si2O5(OH)4.

It is a layered silicate mineral, with one tetrahedral sheet of silica ( SiO 4) linked through oxygen atoms to one octahedral sheet of alumina ( AlO 6).

Explanation

Remember that water has 2 lone pairs on oxygen.

Hence, according to VSEPR theory, the water molecule arrives at a bent or a V-shape

Due to the presence of lone pair-lone pair, lone pair-bond pair and bond pair-bond pair repulsions
