<h3><u>Answer;</u></h3>
Carbon monoxide
<h3><u>Explanation;</u></h3>
- Clean Air Act is a US federal law that is designed to control the pollution of air on a national level.
- Under the clean air act, the environmental protection agency is required to regulate the emission of pollutants which endanger public health and welfare.
- <em><u>EPA is required to the emission of six major pollutants namely: carbon monoxide, nitrogen dioxide, sulfur dioxide, particulate matter, hydrocarbons and photochemical oxidants</u></em>.
Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume. It is a property that can be used to describe a substance<span>.</span><span> It has standard units of kg/m^3 or g/cm^3.</span>
<span> Each atom has a different ability to draw </span>
<span>electrons to itself when it shares electrons (that drawing ability is </span>
<span>called Electronegativity). </span>
A polar covalent means that an atom is electronegative, and the electrons are shared, but not equally.
So, if a bond between two atoms share electrons equally, then it is nonpolar and not electronegative.
If a bond between two atoms aren't shared equally, then it is polar and electronegative. Ex.) A polar molecule is water.
Nickel contains more atoms.
<u>Explanation:</u>
Number of atoms is determined by the Avogadro number.
1 mole of substance contains 6.022 X 10²³ atoms.
Given:
Mass of Nickel, Ni = 3.89g
Molecular weight of Ni = 58.6934g
Number of moles of Ni = 3.89/58.6934g
Number of atoms of Ni =
Number of atoms of Ni = 0.39 X 10²³
Mass of silver, Ag = 6.61g
Molecular weight of Ag = 107.8682g
Number of moles of Ag = 6.61/107.8682
Number of atoms of Ag =
Number of atoms of Ag = 0.36 X 10²³
Therefore, Nickel contains for atoms.
