When the fish water had pH of 8.0, the hydronium ion concentration is 1.0x 10^-8 mole per liter. What is Hydornium ion con ent ration when water had pH of 7.0
Answers
The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
Determine hydronium ion concentration when pH = 7
Given that :
pH = 8.0
Hydronium ion concentration = 1 * 10⁻⁸ mole/liter
Resolving the question
8.0 = 1 * 10⁻⁸ mole/liter
7.0 = x
therefore :
x = 7 ( 1 * 10⁻⁸ ) / 8.0
= 8.75 * 10⁻⁹ mole/liter
Hence we can conclude that The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter

Name these compounds according to IUPAC.
Answers
IUPAC is the universal nomenclature method that is used to give the names of the chemical compounds. The compounds are ethene, propionaldehyde, and propanone.
What are functional groups?Functional groups are the particular side groups that are added to the main chain to exhibit a specific property and character to the atom. In the first compound, the presence of the double bond makes it alkene, and the two carbons make the compound ethene.
The second compound has an aldehydic group with suffix -al and three carbon making it propanal, similarly, the third compound is propanone as it has ketone as the functional group and three carbon atoms in the chain.
Therefore, the compounds are ethene, propanal, and propanone.

If you have 10,000 grams of a substance that decays with a half-life of 14 days, then how much will you have after 28 days?
Round to the nearest whole number.
Answers
Answer:
2500g
Explanation:
Half-life like the name suggests cuts the amount by half. So 10,000 grams would be 5,000 grams in one half-life (14 days). But 28 days is two halflives (14 + 14 = 28), thus 5,000 would be cut in half again to finally be 2500 g.

How many grams of BaCl2 are required to make 1.50L of a 0.60M solution?
Answers
Answer:
187.407g
Explanation:
Moles of solute = Molarity × Liters of solution
Multiply 0.60 M by 1.50L:
0.60 mol/ 1L×1.50L=0.9 mol
To obtain the mass of solute, we will need to the molar mass of BaCl2, which is 208.23g/mol:
Finally, multiply the number of moles by208.23g /mol
0.9mol×208.23g/1mol =187.407g
Boom, you have a mass of:
187.407g
We have C=0.60M, V=150L, M[BaCl2]=208g/mol
—>n=CxV = 0.60x1.50=0.9mol
So m= 0.9x208=187.2gram

Answers
Answer:
2,5,6-trimethyloctane
Explanation:
1) Count the number of carbons in the longest chain. If the structure contains a functional group (e.g. double bond, -OH), they have to be part of the chain that you're counting.
• The straight chain is the longest chain, and it contains 8 carbons
• Without the additional 3 methyl (-CH₃) substituents, it would be called octane (since it is an alkane)
2) Assign location numbers for the substituents, ensuring that they are the lowest possible numbers
• From left to right, we could name it as 2,5,6-trimethyloctane
• From right to left of the parent chain, it would be called 3,4,7-trimethyloctane
• Assigning from left to right gives us the lowest location numbers as the sum of the numbers is 13 instead of 14
• Remember to add 'tri' since we have 3 methyl groups

How many grams of C8H18
is in 405,576.398 mL
Answers
[tex]Molarity X \frac{0.762 mol}{05.576398 L} = Mass[/tex] is the of [tex]C_8H_1_8[/tex] is in 405,576.398 mL.
What is molarity?Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Given data:
Molar mass of [tex]C_8H_1_8[/tex] = 0.762 mol
Volume of solution = 405,576.398 mL = 405,576.398 mL/1000 = 405.576398 L
Solution:
Step 1: Calculating moles of [tex]C_8H_1_8[/tex]
• Molarity =[tex]\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}[/tex]
• Putting the value in the given formula
• Moles of solute C8H18 = [tex]\frac{\;Mass}{\;Molar \;molar \;mass}[/tex]
• Moles of solute C8H18 = [tex]\frac{\;Mass}{0.762 mol}[/tex]
Now,
Molarity =[tex]\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}[/tex]
Molarity =[tex]\frac{\frac{\;Mass}{0.762 mol}}{\;Volume \;of \;solution \;in \;litre}[/tex]
Molarity =[tex]\frac{\frac{\;Mass}{0.762 mol}}{405.576398 L}[/tex]
[tex]Molarity X \frac{0.762 mol}{05.576398 L} = Mass[/tex]
Hence, [tex]Molarity X \frac{0.762 mol}{05.576398 L} = Mass[/tex] is the of [tex]C_8H_1_8[/tex] is in 405,576.398 mL.
