Which type of galaxy contains mostly new stars because it has lots of dust and gas

Which of these are elimination reactions? Check all that apply.

kotykmax [81]

Answer:

C3H7OH → C3H6 + H20

Explanation:

If we look at the reactant and the product we will realize that the reactant is an alcohol while the product is an alkene. The reaction involves acid catalysed elimination of water from an alcohol.

Water is a good leaving group, hence an important synthetic route to alkenes is the acid catalysed elimination of water from alcohols. Hence the conversion represented by C3H7OH → C3H6 + H20 is an elimination reaction in which water is the leaving group.

Write an equation that shows the reaction between acetic acid and triethylamine (CH3CH2)3N. Draw all non-bonding lone electron p

Anni [7]

Answer:

-) Acid-base reaction

-) Carboxylic acid, alcohol, alkene and ketone

Explanation:

For the reaction between acetic acid and triethylamine, we will have an acid-base reaction. Therefore a salt would be produced in this case an "ammonium quaternary salt". Also, we have to remember that on this reaction the acid is the acetic acid and the base is the triethylamine. See figure 1

For the second question, we have to check the structure of Prostaglandin E1 in which we have the functional groups:

1) Carboxylic acid

2) Alcohol

3) Alkene

4) Ketone

See figure 2.

I hope it helps!

Carbon dioxide is a molecule made up of a single carbon atom double bonded to two oxygen atoms. The electrons are shared equally

wolverine [178]

Answer:

The type of bonding does carbon dioxide have is covalent bonding.

Explanation:

There are 2 broadly types of chemical bonds present:

1. Covalent bond: This bond is present when there is sharing of electrons between two elements.

2. Ionic bond: This type of bond is formed when there is a complete transfer of electrons from one element to another element. In this bonding one element is always a metal and another is a non-metal.

We are given that a carbon atom is double bonded to two oxygen atoms. Carbon and oxygen both are non-metals and hence, the bonds between them will be purely covalent in nature.

Also, the valency of the carbon atom is 4. Thus, in the given case, the carbon atom is bonded to 2 oxygen atoms via double bonds. Thus, they all complete their octet by sharing the electrons.

Hence, the type of bonding does carbon dioxide have is covalent bonding.

Identify the limiting and excess reactants when 1.00 g of zinc reacts with 150 mL of 0.250M Pb(NO3)2. How many grams of lead are

Marysya12 [62]

The reaction equation is:
Zn + Pb(NO₃)₂ → Pb + Zn(NO₃)₂

The moles of lead are calculated using:
moles = concentration x volume
moles = 0.25 x 0.15
moles = 0.0375

The moles of zinc are: 1 / 65 = 0.015

We see from the equation that equimolar quantities of zinc and lead should be present. Therefore, lead is in excess and zinc is the limiting reactant.

Calculate the mass of a solute in a 10% salt solution if the mass is 350 grams.

Lyrx [107]

Answer: The mass of a solute is 35 grams

Explanation:

To calculate the mass percentage of solute, we use the equation:

$\text{Mass percent of solute}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$

Mass percent of solute = 10 %

Mass of solution = 350 g

Putting values in above equation, we get:

$10=\frac{\text{Mass of solute}}{350g}\times 100\\\\\text{Mass of solute}=\frac{10\times 350}{100}=35g$

Hence, the mass of a solute is 35 grams
