Answer:

To make a 3.50 M solution, 38.5 moles of solute will be needed if 11 liters of solution are required.

Explanation:

Molarity is defined as a concentration unit that indicates the number of moles of solute per liter of solution. That is, it indicates the number of moles of solute that are dissolved in a given volume. Then, the molarity is calculated by dividing the moles of the solute by the liters (volume) of the solution:

Molarity( M)=\frac{number of moles of solute}{volume}

Molarity is expressed in units (\frac{moles}{liter}).

So, knowing the definition of molarity, you can apply a rule of three as follows: if by the definition of molarity in 1 L of solution there are 3.5 moles of solute, in 11 L of solution how many moles of solute are there?

moles=\frac{11 L*3.5 moles}{1L}

moles=38.5

Answer:

The number of moles is 38.5 moles

Explanation:

Given:

Concentration of the solution = 3.5 M

Volume of solution = 11 L

Question: How many moles of solute, nsol = ?

The molarity is the number of moles of the solute divided by the volume of the solution, in this case:

n_{sol} =Molarity*Volume=3.5\frac{mol}{L} *11L=38.5moles

Which 2 resonance forms destablize the carbocation intermediate if bezonitrile undergoes chlronation at the ortho or para positi
Anna11 [10]

The question is incomplete, the complete question is shown in the image attached

Answer:

A and B

Explanation:

The electrophilic substitution of arenes yields a cation intermediate. The positive charge of the cation is delocalized over the entire ring.

The -CN group directs incoming electrophiles to the ortho/para position. The resonance structures for the chlorination of benzonitrile are shown in the question.

Recall that -CN is an electron withdrawing group. The resonance forms that destablize the carbocation intermediate are those in which the -CN group is directly attached to the carbon atom bearing the positive charge as in structures A and B.

What is true about the position of any metal in the periodic table
Serjik [45]

Answer:

The metals are on the bottom left in the periodic table, and the nonmetals are at the top right. The semimetals lie along a diagonal line separating the metals and nonmetals. The elements are arranged in a periodic table, which is probably the single most important learning aid in chemistry.
