Genetically alter the DNA of a plant to produce a desired trait.
Answer
C6H807 = 192.124 g/mol
n = m/M
n = 0.119 mol
Explanation:
to calculate amount in moles you need to find the molar mass of citric acid then divide the mass of the acid with the molar mass
Answer:
The correct answer is :
1) Fehling's test,
2) Tollen's test
Explanation:
1. Fehling's Test is the test that confirms the presence of aldehydes by the Fehling solution that contain copper ion with tartrate ions in NaOH solution. The color of the solution is blue due to presence of copper ions. In this test aldehydes are confirmed by the reduction of the blue solution to a insoluble precipitate of copper oxide red color while in presence of ketones there is no change.
2. Tollen's test is also a test that help in identifying the presence of aldehyde as the Tollen's reagents oxidizes aldehydes where ketones as they lack hydrogen in them.
Thus, the correct answer is : 1) Fehling's test,
2) Tollen's test.
<span>To get the percent composition of an element in a compound, simply divide the mass of the element by the total mass of the compound. And since we're going to need to calculate the percentage a couple of times, let's first start by calculating the total mass of the compound:
M = 12.2 g + 5.16g = 17.36 g
Now the percentage of magnesium:
12.2 g / 17.36 g = 0.702764977 = 70.3%
And the percentage of nitrogen:
5.16 g / 17.36 g = 0.297235023 = 29.7%
Magnesium = 70.3%
Nitrogen = 29.7%</span>
