 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>

The are different reasons and these are the following:
1) The acid starts to go yellow as the dehydration begins.
2)The rate of dehydration then accelerates as the acid heats up .
3)This expands out of the reaction vessel.

Select the correct answer.
rewona [7]
We can use the formula P=IV to calculate the current, where “P” is power (measured in watts), “I” is current (measured in Amps), and “V” is voltage. Simply plug and solve:

P = IV
(3.5 Watts) = I(120 volts)
I = 0.0292 Amps

The current flowing through the bulb is approximately 0.0292 Amps.

Hope this helps!

A chemist must calculate the amount of an element needed for a chemical reaction. The reaction requires 3.4 moles of silver. Hel
zvonat [6]

Answer:

3.4 moles of silver * 107.868 grams of silver/1 mole of silver = 370 grams of silver.

Explanation:

According to the NYS Reference Table, one mole of silver equates to 107.868 grams. Therefore, if you want to convert from moles to grams, the mole unit should be on the bottom, since it is the unit being cancelled out. Above the mole unit should be the gram unit, since it is the unit you want to convert to. Once you do the math with significant figures, the solution turns out to be 370 grams of silver.
