Answer:
Cs is cesium and CrO₄ is chromate so CsCrO₄ is cesium chromate.
Answer:
a. is actually variable.
Explanation:
Earth's solar constant -
It refers to the total amount of radiations coming from the sun per unit area and per unit time on the surface of the earth , is referred to as Earth's solar constant .
There is an increase of about 0.2 percent during the peak of every 11 year solar cycle and hence ,
The amount is variable in nature .
Since , the sun is composed of hydrogen gas , which increases to around 10 percent on every billion year .
Hence , from the given question ,
The correct option is a. is actually variable.
Answer:
72.3%
Explanation:
The following data were obtained from the question:
Theoretical yield of MgO = 3.43 g
Actual yield of MgO = 2.48g
Percentage yield of MgO =.?
Percentage yield of a reaction can simply be obtained by dividing the actual yield by the theoretical yield multiplied by 100. This is illustrated below:
Percentage yield = Actual yield /Theoretical yield × 100
Thus, we can obtain the percentage yield of MgO as follow:
Theoretical yield of MgO = 3.43 g
Actual yield of MgO = 2.48g
Percentage yield of MgO =.? Percentage yield = Actual yield /Theoretical yield × 100
Percentage yield = 2.48/3.43 × 100
Percentage yield = 72.3%
Therefore, the percentage yield of MgO is 72.3%.
