15. When traveling through a smoke-filled area, a person must be able
maxonik [38]

When traveling through a smoke-filled area, a person must be able to have distance of at least 4 feet in order to safely reach a fire exit. That is option C.

<h3>What is a smoke-filled area?</h3>

Smoke-filled area is an enclosed area that is filled with smoke gas that is usually made up of carbon monoxide.

The smoke-filled area is usually caused by

  • Fire out break

  • Burning of plastics or chemical products

  • Release of fuming gases.

When there is smoke-filled area die to fire out break, there are some guidelines to follow to safely reach the fire exit early enough.

The importance of these guidelines include the following:

  • enable rescuers to navigate a scene more quickly,

  • identify risks and hazards,

  • locate safety points,

  • determine the safest way in and out of a building, and

  • map out evacuation routes.

The affected individual should get down and crawl while taking short breath through the nose because cleaner air is nearest to the floor.

When the experiment was carried out, the temperature was 22 oC and atmospheric pressure was 1.007 atm. Using the Ideal Gas Law a
lesantik [10]

Answer:

number of moles of H_2=4.16mol

Explanation:

experiment data:

temperature= 22^{\circ}C=273+22 k=295k

pressure=1.007 atm

volume is missing so assuming volume-=100L

using ideal law relationship

ideal gas means gas which occupies negligible space and there is no interaction between the molecules of gases.

PV=nRT

put all the experimental data, we get

n=4.15 mol

number of moles of H_2=4.16mol

How many oxygen atoms are in 1.60 g of quartz? hints?
Naily [24]
Quartz has the formula SiO2
From the periodic table:
mass of oxygen = 16 grams
mass of silicon = 28.0855 grams
Mass of one mole of quarts = 28.0855 + 2(16) = 60.0855 grams

number of moles = mass / molar mass
number of moles = 1.6 / 60.0855 = 0.0266 moles

Each mole of quartz contains Avogadro's number of atoms.
Therefore:
number of atoms in 1.6 g = 1.6 x 6.02 x 10^23 = 1.603 x 10^22 atoms
