Heyy,
I hope that you're doing well today! :)
Can you help me please with my chemistry homework?
How are these two formulas called?
Thank youu
Answers
These are structural formulas of constitutional isomers of hexene, an alkene.
Both are acyclic, six-carbon chains, and they differ only in the position of the double bond. As constitutional isomers, both structures have the same molecular formula.
The first structure is of hex-1-ene (or 1-hexene).
The second structure is of (3E)-hex-3-ene [or (3E)-3-hexene].
Both structures have the molecular formula C₆H₁₂.
I hope I answered your question. Please feel free to let me know otherwise.

3.60x10-12 + 3.60x10-11
Answers
Answer:
3.60X10^-12 is equal to 0.360X10^-11 (move decimal one place left)
Now you can add 3.60X10^-11 and 0.360X10^-11:
3.60X10^-11 + 0.360X10^-11 = 3.96X10^-11
You're really just adding 3.60 to 0.36 since the "X10^-11" is the same for both.

transmutation occurs during which type of radioactive decay
Answers
Explanation:
Transmutation, conversion of one chemical element into another. A transmutation entails a change in the structure of atomic nuclei and hence may be induced by a nuclear reaction (q.v.), such as neutron capture, or occur spontaneously by radioactive decay, such as alpha decay and beta decay (qq. v.).

What is the molar mass of Mn2Se7 ?
A.) 601.34 g/mol
B.) 542.50 g/mol
C.) 662.60 g/mol
Answers
Answer:
C. 662.60
Explanation:
the mass of Mn is about 54 grams/mol, (multiply that by 2 since there are 2 Mn's).
the mass of Se is about 79 grams/mol, so multiply that by 7
if you add them, you get 662.60 (approxamitly)
Answer:
C) 662.60
Explanation:
~~55*2 + 79*7 = 110 + 553 = 663 (~~662.60)

Answers
Answer:
6.022 ×10(index 23) / 7.5 = 0.8293 ×10(index 23)
Explanation:
molar mass of C = 12gmol
therefore in 12g of C there is one mole or an amount of 6.022 ×10(index 23)
∴12g/6.02210(index 23) ×1.6g

Answers
The most likely to take place when a solid is placed in a liquid at room temperature ( i.e. 20°C ) is ; ( A ) A chemical reaction
Although your question lacks the required diagram a general answer is provided within the scope of your question
When a solid at 20°C is placed inside a liquid also at 20°C in the laboratory the emergence of gas bubbles shows that there has been a chemical change between the solid and liquid reactant ( i.e. a chemical reaction has taken place ).
Hence we can conclude that what is most likely to have taken place in this situation is a Chemical reaction.

How many moles are in a 18 L tank of nitrogen gas at STP?

12
Explanation:

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.803moles of nitrogen gas are there in a 18 L tank of nitrogen gas at STP.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically,
number of moles of any ideal gas =given volume ÷Volume occupied by one mole of a ideal gas at STP
Volume occupied by one mole of a ideal gas at STP=22.4L
given volume of nitrogen gas= 18 L
substituting all the given values in the above equation we get,
number of moles of nitrogen gas =18 L ÷22.4L
number of moles of nitrogen gas =0.803moles
Therefore, 0.803moles of nitrogen gas are there in a 18 L tank of nitrogen gas at STP.
