(A)Oxidation is your answer..........
Michelle drove 50 miles per hour
Explanation:
300 miles divided by 6 hours equals 50 miles per hour.
Miles per hour basically just means
You can infer from the use of the word 'per' that you should divide the number of miles by the number of hours to get an average speed.
Similarly, to work out the number of miles driven you could say you travelled 50 miles per hour for 6 hours, so you would multiply 50mph x 6 hours to work the equation in reverse.
Answer:
3.00 cm
Explanation:
The absorbance can be expressed using <em>Beer-Lambert's law</em>:
A = ε*b*c
Where ε is a constant for each compound, b is the optical path, and c is the molar concentration of the compound.
Now we <u>match the absorbance values for both solutions</u>, because we want the absorbance value to be the same for both solutions:
A = ε * 1.00 cm * 7.68x10⁻⁶M = ε * b * 2.56x10⁻⁶ M
And <u>solve for b:</u>
ε * 1.00 cm * 7.68x10⁻⁶M = ε * b * 2.56x10⁻⁶ M
1.00 cm * 7.68x10⁻⁶M = b * 2.56x10⁻⁶ M
b = 3.00 cm
Answer:
(4) 266 moles
Explanation:
We have Dinitrogen Pentoxide N2O5
6.41*10^25 molecules are given
No of Moles of N2O5 =
=
= 106.5 mol
Now using Unitary Method
2 Mole of Nitrogen pentoxide require 5 mole of Oxygen to form N2O5
1 mole of N =
In 106.5 mole of N = = 266.25 mole
So, 6.41*10^25 molecules of N2O5 will require 266.25 mole of Oxygen atoms.
Answer:
B. All of the Above
Explanation:
Sea of electrons -
This model of the metallic bonding helps in explaining the properties like , malleability , ductility ,high electrical conductivity , luster ,high thermal conductivity of the metals in solid state .
The metallic bonding is between metal atoms and the ionic bond links a metal and a non - metal together ,
In case of metallic bonding , bulk of metal atoms are joined .
hence from the question , all the given properties are correct .
