The statement that describes a chain reaction brought about by a nuclear reaction is "neutrons <span>released during a fission reaction cause other nuclei to split." This is applicable to fission reactions only wherein atoms split and produce neutrons that also cause further atoms to split, thus creating a chain or series of reactions.</span>
Answer:
<h2>3.31 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 23.2 g
volume = final volume of water - initial volume of water
volume = 62 - 55 = 7 mL
We have
We have the final answer as
<h3>3.31 g/mL</h3>
Hope this helps you
Answer:
26.9 g
81%
Explanation:
The equation of the reaction is;
4 KO2(s) + 2 CO2(g) → 3 O2(g) + 2 K2CO3(s)
Number of moles of KO2= 27.9g/71.1 g/mol = 0.39 moles
4 moles of KO2 yields 2 moles of K2CO3
0.39 moles of KO2 yields 0.39 × 2/4 = 0.195 moles of K2CO3
Number of moles of CO2 = 57g/ 44.01 g/mol = 1.295 moles
2 moles of CO2 yields 2 moles of K2CO3
1.295 moles of CO2 yields 1.295 × 2/2 = 1.295 moles of K2CO3
Hence the limiting reactant is KO2
Theoretical yield = 0.195 moles of K2CO3 × 138.205 g/mol = 26.9 g
Percent yield = actual yield/theoretical yield × 100
Percent yield = 21.8/26.9 × 100
Percent yield = 81%
Answer: The mole to mole ratio are the stoichiometric factors of the chemicals in your balanced reactions and are always in whole numbers. When we balance a chemical reaction, whole numbers are always used for easy convention.
Explanation:
Glucose falls under aldoses group of monosaccharides which are one of the carbohydrates.
<u>Explanation:</u>
Generally, a molecule formed by combination of carbon, hydrogen and oxygen are termed as carbohydrates. The smallest of the saccharides are mono and disaccharides. The saccharides can contain an aldehyde or a ketone group in their structural formula.
The molecular formula of glucose is C6H12O6. It falls under monosaccharide as the molecular formula of monosaccharides are (CH2nO)n where the n will be 3,5 or 6. So the molecular formula of glucose exactly matches with the molecular formula of monosaccharide family.
Also, it is known that glucose contains an aldehyde so it can be termed as aldose for being a carbohydrate in monosaccharide family containing aldehyde group.
