Answer:
40.79
Explanation:
an ounce is equal to approximately 28.3 grams.
if you have 4 ounces then it would be equal to about 113.4 grams. then you would divide that by 2.78 which will equal about 40.8
<span>The average molar bond enthalpy of the carbon-hydrogen bond in a CH4 molecule is 416 KJ/mol.
(+716.7 + (4 x 218) - (- 74.6) ) / 4
= + 1663.3 / 4
= 416</span>
Answer:
You didn't list the compounds it gave you so i cant cross check them to see it they are ionic bonds( which is the chemical bonding is formed between metal and nonmetal)
if you reply with the compounds it list I will be happy to check for you
A lot of values are given but we must focus only on HCl.
<span>There are 215 mL (0.215 L) of 0.300 M HCl that was
completely used. We must remember the
moles is simply the product of volume and molarity, that is:</span>
number of moles = 0.215 L * 0.300 M
<span>number of moles= 0.0645 moles HCl</span>
Answer:
Explanation: AH, AG and AS for the reaction at 873 K
delta G =-RT ln Kp
G= -8.314 x 873 ln 0.9
= 764.7J/mol
AG = AH-TAS
AH = 764.7 - 8314(0.9)
Kp =pCO/pCo2
Substitute the values at different temp. Solve simultaneously
Since mole fraction =kp/pCo
Mf =1.5
