number of hydrogen obtained from 1 mole of hydrochloric acid​

Answer:

From E, draw EF || AB || CD. EF || CD and CE is the transversal.

∴∠DCE+∠CEF=180

o

[∵ Co-interior angles]

⇒x

o

+∠CEF=180

o

⇒∠CEF=(180−x

o

)

Again, EF || AB and AE is the transversal.

∠BAE+∠AEF=180

o

[∵ Co-interior angles]

⇒105

o

+∠AEC+∠CEF=180

o

⇒105

o

+25

o

+(180

o

−x

o

)=180

o

⇒310−x

o

=180

o

Hence, x=130

Step-by-step explanation:

mark me brilliant

2 and 3 is the answer

Step-by-step explanation:

you can write

12xy*2=2*72

12xy=72

xy=6

x*y= 2*3

hence 2, 3 answer

Answer:

The primary cell wall of land plants is composed of the polysaccharides cellulose, hemicelluloses, and pectin.

Algae possess cell walls made of glycoproteins and polysaccharides such as carrageenan, cellulose, hemicellulose and pectins and agar that are absent from land plants. In bacteria, the cell wall is composed of peptidoglycan.

Hence, Algae have cell walls made up of Cellulose, Hemicellulose, and Pectins.

So, the correct answer is 'Cellulose, Hemicellulose and Pectins'.

Answer:

Most of the chemical elements you encounter every day are combined with other elements to form compounds. Here's a gallery of pictures of the pure elements, so you can see what they look like.

The elements are listed in the order in which they appear in the periodic table; the first elements have the lowest atomic number, which increases through the table. Toward the end of the periodic table, there aren't any images of elements. Some are so rare only a few atoms have ever been produced, plus they are highly radioactive, so they often vanish an instant after creation. Yet, many elements are stable. Here's your chance to get to know them.
