Law of definite composition-as long as it has the same formula, it will have the same composition of mass

The Law of Definite Proportions states that a chemical compound will always have the same proportions or amount of each element by weight, no matter what the amount is, or source. For instance, a 50-gram sample of carbon monoxide will have 21.5 g of carbon and 28.5 g of oxygen.

<h3>What is Ibuprofen ?</h3>

The nonsteroidal anti-inflammatory drug family includes ibuprofen, which is a medicine used to treat pain, fever, and inflammation. This includes rheumatoid arthritis, migraines, and painful menstrual cycles. It can also be used to seal a premature baby's patent ductus arteriosus.

1) A toy car with a mass of 2.35 kg is pushed with a force of 21.6 N. What is the acceleration of the car?
Nataly_w [17]

Answer:

The acceleration of the car is 9,19 m/s2

Explanation:

We use the formula: F=m x a---> a=F/m

a=21,6N/ 2,35kg       1N is 1kgxm/s2

a=21,6 kg x m/s2 x 2,35 kg

a=9,191489362  m/s2

Use the molar solubility 3.27×10−11m in pure water to calculate ksp for nis.
Ne4ueva [31]

Answer:

Ksp = 1.07x10⁻²¹

Explanation:

Molar solubility is defined as moles of solute can be dissolved in 1L.

Ksp for NiS is defined as:

NiS(s) ⇄ Ni²⁺(aq) + S²⁻(aq)

Ksp = [Ni²⁺] [S²⁻]

As molar solubility is 3.27x10⁻¹¹M, concentration of [Ni²⁺] and [S²⁻] is 3.27x10⁻¹¹M for both.

Replacing:

Ksp = [3.27x10⁻¹¹M] [3.27x10⁻¹¹M]

<em>Ksp = 1.07x10⁻²¹</em>

<em></em>
