I would say the atoms in the fork are moving faster. 0 degrees Fahrenheit is -17.7778 in Celsius while 0 degrees in Celsius is equal to 32 degrees in Fahrenheit.
Answer:
CO2
Explanation:
(I Just took the test)
At STP 1 mol=22.4 Liters, so we now know that it is asking for which of the gasses has a molar mass of 44, and CO2 is th only one with that molar mass
Answer:
2.4x10² kcal
Explanation:
As the serving of fish contains 50g of protein that is 4.0kcal/g:
50g × (4.0kcal/g) = <em>200kcal</em>
<em> </em>
And in 4g of fat that is 9.1kcal/g:
4g × (9.1kcal/g) = <em>36.4kcal</em>
<em />
That means the kcal of the serving are:
200kcal + 36.4kcal = 236.4kcal
In 2 significant figures: <em>2.4x10² kcal</em>
<em></em>
I hope it helps!

Answer:
Exergonic
Explanation:
The process is exergonic because it transfer energy from the system to the surrounds in the shape of light. It happens because of the Gibbs free energy (ΔG) which is lower than zero. If the reaction was Endergonic, the Gibbs free energy should be higher than zero. We can calculate it from the GIbbs-Helmholtz equation: ΔG = ΔH - T . ΔS. ΔH is enthalpy, T is the temperature and ΔS is entropy.
Answer:
A silicone atom shares an electron pair with each oxygen atom
Explanation:
Because the silicone dioxide molecule has one silicone atom:two oxygen atoms....
Hence...since silicone has four electrons in the outter shell..which are used for bonding...each oxygen atom shares two electrons(an electron pair) with the silicone atom...so as to fill the outter shell of the oxygen atom
