Answer:
NO2 is the molecular formula of nitrogen Oxide
Explanation:
Correct question
An oxide of nitrogen contain its own volume of nitrogen
its vapour dentity is 23. Find the molecular formula
Of nitrogen Oxide
Solution
As we know
Molecular Weight is equal to two times the vapour density
Hence, the molecular weight of Oxide of nitrogen is 2 * 22 = 44
Molecular weight of Oxide of nitrogen is the sum of atomic weight of nitrogen and oxygen
Molecular weight of Oxide of nitrogen = 14 + 16 *Y
14 + 16 *Y = 46
Y = 2
Hence, the formula is NO2
Answer:
gene
Explanation:
DNA is divided into functional units called genes. A gene is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis
Answer:
Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere. Photosynthesis is part of the carbon cycle, and cellular respiration is not. (Only plants perform photosynthesis, and only animals perform cellular respiration )
Explanation:
Answer:
A "squeaky" pop sound is heard.
Explanation:
When a metal reacts with hydrochloric acid, it produces the metal chloride (salt) and further liberates hydrogen gas which is a colourless and odourless gas.
Equation of the reaction
M(s) + HCl(aq) --> MgCl(aq) + H2(g)
A burning splint test is carried out for the identification of gases in the laboratory. A characteristic property of Hydrogen gas is that it gives a distinctive 'squeaky pop' sound.
Hydrogen is easily ignited, as it is flammable over a wide range of concentrations in air.
I think it’s going to be a
