Answer:
- To give further credence, or otherwise to the findings from the other companies.
- To ensure findings from the other companies are not limited to a specific variant of the population
- To check if there are other variables that were not considered by the other companies.
Explanation:
First of all, a part of the question is missing. Below is the complete question
<em />
<em>
Read the passage about the health risks of single-load liquid laundry packets.</em>
<em>These packets are filled with concentrated, toxic chemicals. A 7-month-old in Florida died from swallowing the soap. Several soap and detergent companies are conducting studies to address these safety concerns; they want to reduce toxicity and to make the packets look less like candy. The U.S. Consumer Product Safety Commission (CPSC) is also performing studies to build more safety into these products.
</em>
<em>
Why would the CPSC perform studies when other soap and detergent companies have already conducted research on the same products?</em>
<em />
What CPSC is called replication. Replication is an important attribute of a good research. It has to do with the reproducibility of outcomes from the same research carried out by different researchers using different subjects. The CPSC's need to perform studies on the same product might be out of the following:
- To give further credence, or otherwise to the findings from the other companies.
- To ensure findings from the other companies are not limited to a specific variant of the population
- To check if there are other variables that were not considered by the other companies.
Saturated fats have single bond between the carbon atoms, this makes them a solid at room temperature. Unsaturated fats have at least one double bond between the carbon atoms, which makes them liquid in room temperature.
Answer:
The concentration of an anthracene solution is
Explanation:
From the question we are told that
The incident beam is
The fluorescence intensity is
The length of the medium is b = 0.875 cm
The molar extinction coefficient is
The proportionality constant k = 0.30
According to Lambert law the Absorbance of the anthracene solution is mathematically represented as
Where
and A is the Absorbance
Substituting value
Generally beers law can be represented mathematically as
where c is the concentration of an anthracene solution
Making c the subject of the formula
Substituting 0.875 cm for length = b ,
We have
51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.
<h3>How to find the Number of moles ?</h3>
To calculate the number of moles use the formula
Number of moles =
=
= 1.9 mol
4NH₃ + 5O₂ → 4NO + 6H₂O
4 mol of NH₃ react with oxygen to given 6 mole of water.
So 1.9 mol of NH₃ produces =
= 2.85 mol of water
Mass of water = Molar Mass of water × Number of moles of water
= 18 × 2.85
= 51.3 gram
Thus from the above conclusion we can say that 51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.
