Answer:
It would be 151.832775 because one mole is 44.0095*3.45 i hope this helps!
Explanation:
Answer is: n-octane.
Octane is the straight-chain alkane (an acyclic saturated hydrocarbon) with eight carbon atoms.
Carbons in octane have sp3 hybridization (carbon’s 2s and three 2p orbitals combine into four identical sp3 orbitals).
Orbitals in sp3 hybridization have a tetrahedral arrangement and form single (sigma) bonds.
Burning octane fuel is very fast chemical reaction, it happens in immediately.
Main products of the combustion of fossil fuels are carbon(IV) oxide and water.
Chemical reaction: C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O; ΔH = -5500 kJ/mol.
The answer would be 5. because the last zero is a holding place because the number is in front of the decimal. They other zero counts because they are being sandwiched.<span />
Answer : The nutritional Calories per gram of the candy are, 5.36 calories
Explanation :
First we have to calculate the amount of heat.
where,
q = heat = ?
c = specific heat = 
= change in temperature = 
Now put all the given values in the above formula, we get:
Now we have to calculate the heat for per gram of sample.
Heat = 
Now we have to calculate the heat in terms of calories.
As, 1 nutritional Calories = 1000 calories
and, 1 calories = 4.2 J
As, 4.2 J = 1 calories
So, 22510 J = 
Therefore, the nutritional Calories per gram of the candy are, 5.36 calories

<em><u>PLEASE MARK BRAINLIEST</u></em></h2>
760 mmHg = 1 atm Therefore 30 atm = 760 * 3 mmHg = 2280 mmHg p1 = 700 mmHg p2 = 2280 mmHg You can compare them from there. You may also convert mmHg to atm by dividing by 760.
Your answer would be 243.2 mm Hg
