<h2>Carbon-dioxide</h2>

Explanation:

  • Wildfires are blazes that are impossible to control which burn land by huge amounts and burns over everything that comes in their paths like plant animals and other living creatures.
  • In the mentioned gases, Carbon dioxide is the main reason responsible for wildfire.
  • Carbon dioxide is known to be the main driver behind the warming of the earth 's atmosphere which is mainly induced by humans, and its increase in the concentration in the atmosphere is regularly increasing day-by-day.

Water (H2O) has two O–H bonds. The electronegativity of oxygen is 3.5, whereas hydrogen is 2.1. Which statement best describes t
creativ13 [48]

The statement that best describes the type of bond a molecule of water has and how the electrons behave is : O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it; option D

<h3>What are covalent molecules</h3>

Covalent molecules are molecules which are formed by the sharing of electrons between atoms of two or more elements whose elecyronegativity values are close to each other.

Covalent bonds are usually formed by non-metals such as hydrogen, oxygen, nitrogen to form their gases.

Example of covalent molecules include water and hydrogen gas.

<h3>What are Polar molecules</h3>

Polar molecules are molecules which are formed by the uneven sharing of electrons between atoms or by the formation of ions by substances such that the two ends of the molecule will have different charges, positive and negative.

In polar covalent molecules, the more electronegatibe element pulls the shared electrons more to itself. For example, in a water molecule which is polar, oxygen pulls the shared electrons with hydrogen more to itself to have a partial negative charge while the hydrogen atom has a partial positive charge.

Therefore, statement that best describes the type of bond a molecule of water has and how the electrons behave is : O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it; option D

Under what pressure will a scientist need to store 0.400 miles of gas if the container has a volume of 200.0 mL and the temperat
mihalych1998 [28]
Hello!

Ok so for this problem we use the ideal gas law of PV=nRT and I take it that the scientist needs to store 0.400 moles of gas and not miles.

So if we have
n=0.400mol
V=0.200L
T= 23degC= 273k+23c=296k
R=ideal gas constant= 0.0821 L*atm/mol*k

So now we rearrange equation for pressure(P)

P=nRT/V
P=((0.400mol)*(0.0821 L*atm/mol*k)*(296k))/(0.200L) = 48.6 atm of pressure

Hope this helps you understand the concept and how to solve yourself in the future!! Any questions, please feel free to ask!! Thank you kindly!!!
