Answer: A reversible reaction is a reaction that takes place in back and front directions. If the reaction were to reach equilibrium, the rate of forward direction would be equal to that of the reverse reaction.

Explanation:

Reversible reactions :

These are the reaction in which reactants reacts to give product and products reacts to give reactants as a product in return.

$A+B\leftrightharpoons C+D$

In above equation, 'A' and 'B' are reacting together to give 'C' and 'D', as products and vice-versa.
When the above reaction reaches equilibrium the rate of forward and backward reaction becomes equal.

How many moles are in 7.8 g of acetamide, CH3CONH2?

atroni [7]

Answer:

.13 moles

Explanation:

To begin this problem:

First you need to find the molar mass of acetamide, to do so:

C=12g, H=1.008g, O=16g, and N=14g

2(12)+5(1.008)+1(16)+1(14)=59.04

To find moles when given grams, we divide grams by the molar mass.

7.8g/59.04g/mol=.13 moles

Using 2 sig figs from what we are given, this is our final answer.

Which is the best reason for choosing the beaker for heating the solution? The beaker is the only container that can withstand h

lyudmila [28]

Answer: The beaker will not tip over when placed on the hot plate

Justification:

Since beakers have flat surface bottoms (usually and this is the condition to use them for this particular application) they can be placed safely on the hot plate without the risk that the they tip over.

Beakers are wide mouth cylindrical vessels used in laboratories to store, mix and heat liquids. Most are made of glass, in which case the glass is resistant to the flame and does not break when exposed to high temperatures or when is heated by direct contact on a hot plate.

So, their safe shape (flat bottom) that makes them stable, along with their ability to withstand high temperatures, make them suitable to heat solutions in laboratories.

Need help with a chemistry question

DerKrebs [107]

Answer:

Sn2 mechanism reaction

Explanation:

In this case, we have a primary substrate (1-bromo-3,3-dimethylbutane). Because the leaving group "Br" is bonded to a primary carbon. Additionally, the nucleophile will come from the "NaI" (sodium iodide). This is an ionic compound, so, in solution, a cation and an anion would be produced. The anion $I^-$ would be the nucleophile.

Due to the primary substrate, we will have an Sn2 reaction. So, the attack of the nucleophile and the removal of the leaving group will take place in 1 step. Producing a "transition state" and finally and the final product (1-iodo-3,3-dimethylbutane).

See figure 1

I hope it helps!
