C2H2 is the right answer I believe
Answer:
The answer is
<h2>1.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 10 g
volume = 10 cm³
It's density is

We have the final answer as
<h3>1.0 g/cm³</h3>
Hope this helps you
The gases like nitrogen and oxygen are not greenhouse gases because they do not absorb infrared radiation.
<h3>What are Greenhouse gases?</h3>
Greenhouse gas is a gas that has the property of absorb infrared radiation from the Earth’s surface and reradiate back to the Earth’s surface, thus contributing to the greenhouse effect.
<h3>What is infrared radiation?</h3>
Infrared radiation is an electromagnetic radiation with wavelengths longer than those of visible light.
Carbon dioxide, nitrous oxide, methane, and water vapour are the most important greenhouse gases.
Hence, nitrogen and oxygen are not greenhouse gases despite being in the atmosphere.

#SPJ2
Answer:
A
Explanation:
By nature, a hybrid has one dominante allele and one recessive allele
Aromatic compounds are compounds that contain carbon-carbon multiple bonds.
The question did not mention that a heteroatom is present in the compound so we can assume that there is none of such. In that case, the compound contains only hydrogen and carbon.
So,
(CH)n = 78
where n is the number of each atom present.
(12 +1)n = 78
n = 78/13
n = 6
The molecular formula of the compound is C6H6
When C6H6 is treated with .conc.HNO3/conc.H2SO4 the compound shown in image 1 is formed. The reaction occurs at the C-C multiple bond.
When C6H6 is reacted with chlorine in the presence of sunlight, hexachlorobenzene (shown in image 2 attached) is formed.
