Answer:
Mean rate of reaction produced = 0.533 g/sec (approx.)
Explanation:
Given:
Reaction produced = 1.6 gram
Time taken = 30 sec
Find:
Mean rate of reaction produced
Computation:
Mean rate of reaction produced = Reaction produced / Time taken
Mean rate of reaction produced = 1.6 / 30
Mean rate of reaction produced = 0.533 g/sec (approx.)
Answer:
The answer is C. The partial pressure of hydrogen will be unchanged.
Explanation:
⇒ 
Argon with electronic configuration 
(that is atomic number 18) is an inert gas making it unreactive and it's addition to the reaction has no effect on the partial pressure of either the reactant or production or the state of the system.
The partial pressure of hydrogen will remain unchanged on the addition of Argon.
Answer:
If garlic repels fleas, then a dog that is given garlic every day will not get fleas. Bacterial growth may be affected by moisture levels in the air. If sugar causes cavities, then people who eat a lot of candy may be more prone to cavities.
Explanation:
Answer:
1.5*10^(-2)
Explanation:
0.015 is the answer for (3*10^2)*(5*10^-5)
(3*100)*(5*0.00001)
300*0.00005 = 0.015
1.5*0.001 = 0.015
<h3> Part A</h3>
The molar mass of silver = 107.87 g/mol ( <em>from periodic table)</em>
<h3>
part B</h3>
The moles of silver is 0.2946 moles
<u><em>calculation</em></u>
moles =mass÷ molar mass
= 31.78 g ÷ 107.87 =0.2946 moles
<h3>part c</h3>
The number of atoms of silver that are in this sample is 1.773 x 10²³ atoms
<u><em>calculation</em></u>
According to Avogadro's law 1 mole = 6.02 x 10²³ atoms
0.2946 moles= ? atoms
by cross multiplication
= [ (0.2946 moles x 6.02 x 10²³ ) / 1 mole] = 1.773 x 10²³ atoms
