Answer:
0.1 mol
Explanation:
Number of mole= mass/molar mass
lithium have a mass number of 7 and oxygen have a mass number of 16.
so, (7x2) + 16
= 30
therefore, number of moles = 2.93/30
= 0.10
Answer:
A. discuss the issue with your instructor.
Explanation:
If a lab experiment is not completed then one should discuss it with their instructor because instructor guides how to perform the experiment and also gives instructions to avoid any mis-happening during experiment.
No one should perform any experiment without their instructor in school or college as it can be dangerous to experiment with chemicals or other experimental devices without any supervision.
Hence, the correct option is "A".
Answer:
1038.96 kPa
Explanation:
We’ll use the ideal gas law; P1V1/T1 = P2V2/T2
P1*14.8/75.5 = 101.3*16.5/70.2
P1 = (101.3 * 16.5 * 75.5) / (70.2 *14.8)
P1 = 1038.96

Explanation:
Answer:
carbohydrate, 6, a carbonyl, disaccharide
Explanation:
Fructose is an example of a ketohexose. The -hexose part of the name indicates that fructose is a carbohydrate that contains 6 carbons. <em>There are more isomers that are ketohexoses.</em>
The keto- part of the name indicates that fructose contains a carbonyl functional group. <em>In ketones, the carbonyl is in an inner carbon.</em>
Fructose can combine with glucose to form sucrose. Therefore, sucrose is a disaccharide. <em>Disaccharides are formed by the bonding of 2 monosaccharides.</em>
