A child has a toy balloon with a volume of 1.80 L. The temperature of the balloon when it was filled was 293 K at a pressure of
Mekhanik [1.2K]

Answer:

2.42L

Explanation:

Given parameters:

V₁  = 1.8L

T₁ = 293K

P₁  = 101.3kPa

P₂ = 67.6kPa

T₂  = 263K

Unknown:

V₂ = ?

Solution:

To solve this problem, we are going to use the combined gas law to find the final volume of the gas. The combined gas law expression combines the equation of Boyle's law, Charles's law and Avogadro's law;

               \frac{P_{1} V_{1} }{T_{1} }   = \frac{P_{2} V_{2} }{T_{2} }

All the units are in the appropriate form. We just substitute and solve for the unknown;

         101.3 x 1.8 / 293    =     67.6 x V₂  /  263

          V₂   = 2.42L

How many kilograms of oseltamivir would be needed to treat all the people in a city with a population of 400000 people if each p
enyata [817]

Answer:

300 kg

Explanation:

The give parameters obtained from a similar question are;

The mass of oseltamivir per capsule = 75 mg

The mass of oseltamivir required, <em>M</em>, is given as follows;

M = The mass of oseltamivir per capsule × The mass taken per person per day × 5 days × The number of people in the city

M = 0.75 mg/capsule × 2 capsule/(day·person) × 5 days × 400,000 people

M = 300,000,000 mg = 300 kg

Yuri [45]

Answer:

Nonmetals

Explanation:

Nonmetals typically lacks the metallic bonding which allows substances to exhibit metallic properties that confers special properties on them.

  • Metals are malleable and ductile
  • They are also able to conduct electricity due to the sea of electrons present within their structure.
  • Metals can be made into wire and drawn into sheets.

Nonmetals lacks these properties but metalloids are able to show some of the properties under certain and special conditions.
