Answer:
α-ketoglutarate; oxaloacetate
Explanation:
In the malate aspartate shuttle, glutamate is converted to α-ketoglutarate in the mitochondria by the enzyme glutamate dehydrogenase while aspartate is converted to oxaloacetate in the cytosol by the enzyme aspartate aminotransferase.
An important enzyme in the malate aspartate shuttle, is malate dehydrogenase. In the shuttle system, it is present in the mitochondria and in the cytosol and catalyzes the enzymatic reaction in opposite direction.
Answer:
$89.69
Explanation:
$1000 = 1 oz = 28.3g
volume = mass/density
volume = 28.3/19.3 = 1.47cm³
1 inch= 2.54 cm
1 cubic inch = (2.54)³ = 16.39 cm³
16.39/1.47 = 11.15 cubic inch
11.15 cubic inch = $1000
1 cubic inch = 1000/11.15 = $89.69
First lets calculate the moles of aluminum (molar mass is 27 gram/mol):
n = m/M = 14.9 / 27 = 0.551 mole of Al
According to the reaction between sulfuric acid and aluminum:
From 2 moles of aluminum ==> we get 3 moles of Hydrogen gas
so, let's do cross multiplication
0.551 ==> 0.551 * 3/2 = 0.83 mole of H2
So, from this reaction we got 0.83 mole of H2 gas
knowing that the molar mass of H2 is 2 gram/mol, the mass of the gas is.
m = n * M = 0.83 * 2 = 1.66 gram of H2
Answer:
C. Rate = k[H2]^2[O2]
Explanation:
Rate law only cares about REACTANTS. Since, rate law can only be determined experimentally, I am assuming the given reaction mechanism is elementary reaction from which we can write the rate law.
Only H2 and O2 are part of rate law since they are reactants and also the coefficient in front of H2 goes as exponent on rate law to indicate the order of H2 in the reaction.
Rate= k [H2]^2 [O2]
