Answer:
7.9 × 10⁻⁹ M
Explanation:
Step 1: Given data
pH of the ocean: 8.1
Step 2: Calculate the concentration of hydronium ions
We will use the definition of pH.
pH = -log [H⁺] = -log [H₃O⁺]
[H₃O⁺] = [H⁺] = antilog -pH
[H₃O⁺] = antilog -8.1 = 7.9 × 10⁻⁹ M
Since [H₃O⁺] < 10⁻⁷ M, the solution is basic.
I believe this would be the solution. Remember to first convert mass of KClO3 to moles and then use the mole to mole ratio to find the moles of KCl produced, and then convert this value into grams. To solve for the mass of KCl produced.
Answer:
Explanation:
We can start with the <u>reaction of hydrogen and nitrogen to produce ammonia</u>, so:
When we <u>balance</u> the reaction we will obtain:
Now, the <u>production of nitric acid</u> with oxygen would be:
If we <u>balance</u> the reaction we will obtain:
Now, if we put the reactions together we will obtain:
We can <u>multiply</u> the second reaction by "2":
We have "" on <u>both sides</u>. In the first reaction is in the right in the second reaction is on the left. Therefore we can <u>cancel out</u> this compound and we will obtain:
On this reaction, we will have 2 nitrogen atoms on both sides, 6 hydrogen atoms on both sides, and 8 oxygen atoms on both sides. So, this would be the <u>net reaction</u> for the production of nitric acid.
Sugar is considered an organic compound,
Because it is made up a long chain of carbon atoms.
Answer:
The pressure of the gas is 0.278 atm
Explanation:
Step 1: Data given
Number of moles of the ideal gas = 0.540 moles
Volume = 35.5 L
Temperature = 223 K
Step 2: Calculate the pressure of the gas
p*V = n*R*T
⇒with p = the pressure of the gas = TO BE DETERMINED
⇒with V= the volume of the gas = 35.5 L
⇒with n = the moles of the gas = 0.540 moles
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature of the gas = 223 K
p = n*R*T / V
p = 0.540 * 0.08206 * 223 / 35.5
p = 0.278 atm
The pressure of the gas is 0.278 atm
