No it’s a decomposition reaction
Explanation:
Hint- look where the arrow is
If there is 1 product with an arrow next to it, then it is a decomposition reaction
This shows a product decomposing (breaking down) into 2 elements, which is a decomposition reaction
D. The Moon is the Earth's largest natural satellite.

Molar mass NaOH = 39.997 g/mol
Number of moles :
n = mass of solute / molar mass
n = 11.5 / 39.997
n = 0.287 moles
Therefore :
Molarity = moles solute / volume
Molarity = 0.287 / 1.5 => 0.1913 M
Answer:
79.4 %
Explanation:
From the question given above, the following data were obtained:
Theoretical yield = 3.4 kg
Actual yield = 2.7 kg
Percentage yield =?
Percentage yield is simply defined as the ratio of the actual yield to that of the theoretical yield multiplied by 100 i.e
Percentage yield = Actual yield/Theoretical yield × 100
With the above formula, we can obtain the percentage yield as follow:
Theoretical yield = 3.4 kg
Actual yield = 2.7 kg
Percentage yield =?
Percentage yield = Actual yield/Theoretical yield × 100
Percentage yield = 2.7/3.4 × 100
Percentage yield = 79.4 %
Thus the percentage yield is 79.4 %
