You should know this I am learning it this year and I am in 8th grade) Hydrogen<span>,</span><span>Carbon ,<span>Nitrogen and </span><span>Oxygen

<span>C. 5 protons, 5 electrons, and 6 neutrons</span>
We can use a ratio to solve this question. Lets refer to the amount formed by the formula as a serving
1 serving needs 3/8 gal
We want to create 7/9 servings extra, so
1 + 7/9 = 16/7
1 : 3/8
16/7 : x
1/(3/8) = (16/7) / x
8 / 3 = 16x / 7
x = 7/6
He needs to use 7/6 gallons of water.
Answer:
The presion is 0.6 atm
Explanation:
P1V1=P2V2
P2 = P1V1/V2
P2 = (4.00 atm * 0.30 L) / 2.0 L
P2= 0.6 atm
2C₆H₁₄+19O₂⇒14H₂O+12CO₂+energy
You can tell that the energy is on the left side since the reactoin is highly exothermic meaning it releases heat which can also be thought of as energy.
I hope this helps
