Answer:

Chiral:

3-Methyl-2-butanol

Achiral:

1-Pentanol

3-Pentanol

3-Methyl-1-butanol

Explanation:

Only the molecule that bears a carbon atom surrounded by 4 different groups can be said to be Chiral, the other molecules don't satisfy this property.

Answer:

C5H12O has eight isomers

Chiral isomers are:

Pentan-2-ol

2-Methylbutan-1-ol

3-Methylbutan-2-ol

Achiral isomers are:

Pentan-1-ol

Pentan-3-ol

3-Methylbutan-1-ol

3-Methylbutan-2-ol

2, 2-dimethylpropan-1-ol

Explanation:

C5H12O has eight isomers out of which three are chiral and five are achiral in nature

The isomers that have carbon atom(s) that are surrounded by four different groups are Chiral in nature while those that do not have such carbon atom(s) are achiral.

Thus, only pentan-2-ol, 2-methylbutan-1-ol and 3-methylbutan-2-ol which have carbon atoms surrounded by four different groups are chiral. The carbon atom carrying the hydroxyl (-OH) group is the chiral carbon atom in these three isomers. While the carbon atoms in the other five isomers are achiral.

How many hydrogen atoms are in 5.70 mol of ammonium sulfide?

QveST [7]

There are 2.74603 * 10^25 hydrogen atoms. Ammonium sulfide is represented by (NH4)2S. This means that there are 8 hydrogen atoms total. There are also 8 mol of H in ammonium sulfide. We also need to use avogadroâ€™s number of 6.022 * 10^23. Hydrogen Atoms = 5.7mol * (8mol / 1mol) * 6.022 * 10^23 per mol Hydrogen atoms = 2.74603 * 10^25 hydrogen atoms.

using the symbol M for the element, write the chemical formula for the compound that forms when element M reacts with iodine.

Anon25 [30]

Answer : The chemical formula for the compound is, $MI$

Explanation :

When the element 'M' react with the $I_2$ to give $MI$ .

The balanced chemical reaction is,

$2M+I_2\rightarrow 2MI$

In this reaction, 'M' is in mono-atomic form and $I_2$ is in diatomic form.

By the stoichiometry,

2 moles 'M' react with the 1 mole of $I_2$ to give 2 moles of $MI$ .

Therefore, the chemical formula of the compound is, $MI$

Answer:

Verdadero (True).

Explanation:

Después de la desintegración del citado virreinato, los nuevos Estados intentaron establecer sus fronteras, a menudo a través de guerras e invasiones. Cabe destacar la invasión brasileña de Uruguay o la Guerra de la Triple Alianza. En menor medida, lo hicieron a través de tratados internacionales. (After the disolution of the viceroyalship described above, the new States attempted to establish their frontier usually by wars and invasions. It is to highlight the Brazilian invasion of Uruguay or the Triple Alliance' War. In a lesser extent, they made it through international treaties.)

Allisa [31]

Answer:

A. 5 N to the left

Note: The question is incomplete. The complete question is given below:

With a force of 5 newtons, Amanda pushes the stack of books to the right. At the same time, Jeremy, her little brother, pushes the stack of books to the left with a force of 10 newtons.

What is the direction and magnitude of the resulting force?

A. 5 N to the left

B. 5 N to the right

C. 10 N to the right

D. 10 N to the left

Explanation:

Forces are vector quantities.

Vector quantities are quantities that can be represented both in magnitude and direction.

Forces have both magnitude and direction. Forces can be directed positively or negatively.

For example, in the question above, if forces acting to the right are considered to be in the positive direction, forces acting to the left are considered to be acting in a negative direction.

In the addition of forces, both their magnitude and direction are taken into consideration.

In the example above, taking forces acting to the right as positive and to the left as negative, the sum of the forces is:

Resultant force, F = (5 N) + (-10N)

F = -5 N

Therefore, the net force is 5 N and is directed towards the left
