Answer:
lowest to Highest
Carbon atom
Methane molecule (CH4)
Graphite
Diamond
Explanation:
A carbon atom would be the lowest complexity on this list, that is because it is a lone molecule with no other bonding between other atoms. The same forces interacting between the carbon atom would be the same for the others.
Next would be methane. Methane is a hydrocarbon composed of a single carbon atom bonded covalently with four hydrogens. The electrons within the hydrogen atoms repel each other causing them to be dispersed around the carbon atom to form a
tetrahedral shape. While more complex, the other two are continuous structures made from carbon atoms bonded to gather to form crystal structures.
Graphite is considered to be a crystal structure, just like a diamond. However, the biggest difference between them is their atomic and crystal frameworks. Diamonds have a rigid 3-dimensional structure whilst graphite is composed of 2d planes of graphite with carbon-carbon double bonds connecting the layers. Due to this, a diamond would be more complex then grpahite
Answer:
D. 1.0 x 10-8.43
Explanation:
The pH is an unit of concentration in chemistry used to determine the acidity -or basicity- of a particular solution. Is used in quality control to determine the security of a product for consumers.
The equation is:
pH = -log [H₃O⁺]
As pH = 8.43:
8.43 = -log [H₃O⁺]
10^-8.43 = [H₃O⁺]
1.0x10 -8.43 = [H₃O⁺]
Right option is:
<h3>D. 1.0 x 10-8.43
</h3>
Answer: 1.1 moles H2O
Explanation: It looks like the equation is already balanced for you, so the first step will be to convert 144.1 grams of HNO3 to moles. To do this find the molar mass, and use to to do your conversion.Using the numbers provided for mass, this is the equation:1(1.0) + 1(14) + 3(16) = 1 + 14 + 48 = 63 g/mol144.1 g HNO3 x 1 mol HNO3 = 2.287 mol HNO3 63 g HNO3Now that you know how many moles of HNO3 you're starting with, use the ratio of moles in the equation to find the moles of H2O produced. The coefficient of HNO3 is 8, and H2O is 42.287 mol HNO3 x 4 mol H2O = 1.144 mol H2O 8 mol HNO3
It should just be one for it to be balanced.
Answer:
Heavy Snowfall
High Winds
Extremely Low Temperatures
Reasoning:
Lots of snow, kinda self explanatory
high winds are needed to carry the snow that fast
its has to be below freezing for snow to even form
