How many moles are in 8.8 x 1024 atoms of magnesium?
Veseljchak [2.6K]

Answer:

15 mol Mg

Explanation:

Step 1: Find conversions

Avagadro's Number: 6.022 × 10²³

Step 2: Use Dimensional Analysis

8.8(10)^{24} \hspace{3} atoms \hspace{3} Mg(\frac{1 \hspace{3} mol \hspace{3} Mg}{6.022(10)^{23} \hspace{3} atoms \hspace{3} Mg} ) = 14.6179 mol Mg

Step 3: Simplify

We have 2 sig figs.

14.6179 mol Mg ≈ 15 mol Mg

In the diagram, which letter is altered by a catalyst? <br><br> A<br> B<br> C<br> D
Yanka [14]

Answer:

A

Explanation:

A catalyst refers to an enzyme composed of peptides in their tertiary conformation.  

The addition of a catalyst provides a new path to the reaction and the reaction proceeds in a faster way compared to the reaction without a catalyst.

The peptides are arranged in such a way that they form a pore-like structure which allows the binding of the substrate molecules by forming a temporary covalent bond. These bonds lower the activation energy of the complete reaction which is required to initiate a reaction.

In the given diagram, the activation reaction is represented by the letter "A" and therefore a catalyst will lower and alter the value of A.

Thus, Option-A is correct.

What is the main reason that it takes 2 to 3 minutes for the reaction to occur between sucrose and sulfuric acid in the dehydrat
soldier1979 [14.2K]

 There is a time delay of almost two to three minutes before the reaction proceeds because of the following processes:

<span>1)    </span><span> The acid starts to go yellow as the dehydration begins.</span>

<span>2)    </span><span> The rate of dehydration then accelerates as the acid heats up because the reaction is exothermic/chemical (releases energy by light or heat).  As the sugar molecules are stripped of water, the heat generated turns the water into steam which then expands the remaining carbon into a porous, smoking, black column.</span>

<span>3)    </span>This expands out of the reaction vessel, producing a choking acrid vapor and the smell of burned sugar.

<span> At this stage, sulfuric acid is highly corrosive and will burn skin so one must avoid contact with it. </span>
