A chunk of a metal alloy displaces 0.58 L of water and has a mass of 2.9 kg. What is the density of the alloy in g/cm3?

The answer is actually 3, believe me.

Explanation:

To start, consult the periodic table to pinpoint the element with an average atomic mass of 24.3. The amu is simply the number listed under the element, leading us to conclude that Mg is the answer.

Answer:

The revised net worth rounded to three significant figures is $80.2 billion.

The donation to charity amounts to $100,250,000.

Explanation:

Initial net worth is $77.0 billion.

Stock gains are $3.20 billion.

Calculating new net worth: $77.0 billion + $3.20 billion = $80.20 billion.

Hence, new net worth to three significant figures is $80.2 billion.

One-eighth of a percent is calculated as (1/8 x 1) / 100 = 0.00125.

The charitable contribution amounts to 0.00125 X $80.2 billion = $100,250,000.

Alternatively, $80,200,000,000 divided by 100 results in $802,000,000.

I believe this question has five choices available:

 

>an SN2 process has happened with reversal of configuration

>racemization followed by an S N 2 reaction

>an SN1 process has occurred resulting in reversal of configuration

>an SN1 reaction has taken place due to the formation of a carbocation

>an SN1 event followed by an S N 2 “backside” attack

 

 

 

The correct choice is:

an SN1 reaction has occurred due to carbocation formation
