Over the last few days, NASA has been getting everybody excited with its plans to hold a high profile briefing about a discovery beyond our solar system. Now we know that the announcement concerns the discovery of seven planets orbiting a star elsewhere in our galaxy<span>. hope this helps</span>
Answer:
-second
Explanation:
6-ethyl-2-octyne is an unsaturated compound with a triple bond.
6-ethyl-2-octyne will have a triple bound attached to the second carbon. The suffix -yne suggests that compound carry a triple bond and the number "2" before suffix refers to the position of triple bond that is second carbon.
Hence, the correct option is "-second ".
Answer:
The answer is a compound.
it is a compound as it contains different elements
Explanation:
Answer:
+6
Explanation:
We are given;
We are required to determine the oxidation number of S in the compound.
We need to know that;
- The total oxidation number of this compound is Zero
- Oxidation number of Ba metal is +2
- Oxidation number of Oxygen atom is -2
- There is 1 atom of Ba, 1 atom of S and 4 atoms of O in the compound.
Therefore; assuming oxidation number of S is x
Then, (1× 2) + (1 × x) + ( 4 ×(-2)) = 0
2 + x - 8 = 0
x = 6 or +6
Thus oxidation number of Sulfur in BaSO₄ is +6.
Answer:
Lipids.
Explanation:
Steroids are known as the type of lipid which consists of 4 rings of carbon atoms. All steroids have 1 five-sided carbon ring and a 3 six-sided carbon ring. They are works as a hormone in the body and secreted by the ovaries and testes.
Steroids differ in functional groups. When this functional group attached to the steroid ring it gives steroids with a different function. They are composed of largely carbon, and hydrogen atoms. They are insoluble in nature in water.
