The answer is b. as a whole, the species is mutually beneficial to carry on each others traits and exist in the same ecosystem.
Explanation:
Hydrogen does not obey the octet rule. Boron does not always
obey the octet rule and in fact forms Lewis acids such as BF3 which
only has 6 electrons.
Answer:
1.0975 atm.
Explanation:
<em>According to Boyle’s Law:</em> "
At constant temperature , the volume of a given quantity of a gas varies inversely with its pressure".
P α 1/V.
<em>∴ P₁V₁ = P₂V₂.</em>
P₁ = 4.39 atm, V₁ = 0.5 L.
P₂ = ??? atm, V₂ = 2.0 L.
<em>∴ P₂ = P₁V₁/V₂</em> = (4.39 atm)(0.5 L) / (2.0 L) = <em>1.0975 atm.</em>
Density is the measure of a material's mass per unit volume, used in many aspects of science, engineering and industry. Density can be calculated by dividing an object's mass by its volume. Since different materials have different densities, measuring an object's density can help determine which materials are in it. Finding the density of a metal sample can help to determine its purity.When measuring liquids and regularly shaped solids, mass and volume can be discovered by direct measurement and these two measurements can then be used to determine density. Using a pan balance, determine and record the mass of an object in grams. Using a vernier caliper or ruler, measure the length, depth and width of the object in centimeters. Multiply these three measurements to find the volume in cubic centimeters. Divide the object's mass by its volume to determine its density. Density is expressed in grams per cubic centimeter or grams per milliliter.
