It is going to be too low because the mass mistakenly used is lower than the initial.
<u>Answer:</u>
<em>The specific heat capacity for gold in 105 joules which are required to heat 30.0 grams of gold is 0.129 J/(g℃)</em>
<u>Explanation:</u>
We make use of the formula
where
∆T = final T - initial T
= 54.9℃ - 27.7℃ = 27.2℃
Q is the heat energy in Joules = 105J
c is the specific heat capacity = ?
m is the mass of Gold = 30.0g
Rearranging the formula
So,
c = 0.129 J/(g℃)
(Answer)
Answer:
premium: 91 octane rating
Explanation:
Octane number refers to the percentage or volume fraction of isooctane in a fuel.
The octane number gives a picture of how safe a fuel is for an engine. The higher the octane rating the lesser the tendency of the fuel to cause knocking of the engine.
The type of gasoline with the highest percentage of octane among the options is premium.
When P1/P2 = C1/C2
and C is the molarity which = moles/volume
so, P1/P2 = [(mass1/mw)/volume] / [(mass2/mw)/volume]
P1/P2 = (mass1/mw)/1.5L / (mass2/mw)/1.5L
so, Mw and 1.5 L will cancel out:
∴P1/P2 = mass1 / mass2
∴ mass 2 = mass1*(P2 / P1)
= 0.278g * (78 bar / 62 bar)
= 0.35 g
∴ the quantity of argon that will dissolve at 78 bar = 0.35 g
Answer:
B) stabilization by hydration
C) resonance stabilization
E) increase in entropy
Explanation:
The high phosphoryl potential of ATP results from structural differences that exist between ATP and it's product of hydrolysis. There is higher phosphoryl transfer potential from ATP than glycerol 3-phosphate.
There are some factors associated to the high phosphoryl-transfer potential of ATP which are;
1.)Electrostatic repulsion
2.) Resonance stabilization
3.) Increase in entropy.
4. Stabilization by hydration.
ATP has a phosphoryl-transfer potential which lyes between high phosphoryl-potential compounds that is a derivation of fuel molecules and acceptor molecules that needs the adequate addition of a phosphoryl group for cellular needs.
