Answer:
101
Explanation:
Provided that
And,
Now we expect the same
{S} (0.1mM)
This determines that 
generates a higher rate of product formation as compared to the 
So we can easily calculate the 
for either of or as we know that Tube 1 is and tube 2 is
As we know that
As the rates do not include any kind of units so we do not consider the units for
Now the calculation is
= 100.5
≈ 101
Answer:
496 g
Explanation:
Let's consider the reaction between ethanol and oxygen to form acetic acid and water.
CH₃CH₂OH + O₂ → CH₃COOH + H₂O
The molar ratio of CH₃CH₂OH to CH₃COOH is 1:1. The moles of acetic acid produced by the reaction of 8.26 moles of ethanol are:
8.26 mol CH₃CH₂OH × (1 mol CH₃COOH/1 mol CH₃CH₂OH) = 8.26 mol CH₃COOH
The molar mass of acetic acid is 60.05 g/mol. The mass corresponding to 8.26 moles is:
8.26 mol × 60.05 g/mol = 496 g

Answer:
<h3>The answer is 0.67 cm³ </h3>
Explanation:
Density of a substance can be found by using the formula
<h3>
</h3>
Making volume the subject we have
<h3>
</h3>
From the question
mass of gold nugget = 13 g
Density = 19.3 g/cm³
Substitute the values into the above formula and solve for the volume
We have
<h3>
</h3>
= 0.673575
We have the final answer as
<h2>0.67 cm³</h2>
Hope this helps you
