Answer:
The correct answer is: X is nitrogen dioxide, and Y is a metal oxide
Explanation:
Combustion of compound of containing nitrogen and metal will give nitrogen dioxide and metal oxide as product. During combustion reaction a compound reacts with oxygen in order to yield oxides of elements present in the compound.
The general equation is given as:
Hence, the correct answer is :X is nitrogen dioxide, and Y is a metal oxide.
<h2>Natural Abundance for 10B is 19.60%</h2>
Explanation:
- The natural isotopic abundance of 10B is 19.60%.
- The natural isotopic abundance of 11B is 80.40%.
- The isotopic masses of boron are 10.0129 u and 11.009 u respectively.
For calculation of abundance of both the isotopes -
Supposing it was 50/50, the average mass would be 10.5, so to increase the mass we need a more percentage of 11.
Determining it as an equation -
10x + 11y= 10.8
x+y=1 (ratio)
10x + 10y = 10
By taking the denominator away from the numerator
we get;
y = 0.8
x + y = 1
∴ x = 0.2
To get percentages we need to multiply it by 100
So, the calculated abundance is 80% for 11 B and 20% 10 B.
Answer:
If a compound is made from a metal and a non-metal, its bonding will be ionic.
If a compound is made from two non-metals, its bonding will be covalent.

Answer:
The amount of C2H4I2 produced is maximized if
-Adding C2H4 to the reaction mixture
-Decreasing the reaction volume
-Also can include: raising the reaction temperature
Answer:
4 tert-butylcyclohexane will have the higher Rf value when ethyl acetate is used as the developing solvent because the 4-tert-butylcyclohexanol is the more polar compound that can form hydrogen bonds with the polar silica gel stationary phase.
this means less polar 4-tert-butylcyclohexanol will have a higher Rf
