<u>Answer:</u>

<em>Atomic number 75 is dedicated to an element named rhenium and has been given Re as its chemical name.</em>

<u>Explanation:</u>

With a really low concentration it is one of the rarest metals that is found in Earth's crust.

Like all other elements rhenium also has certain isotopes among with 185 and 187 are the most stable ones. Hence these two are the ones that are naturally available abundance is 34% and 63% respectively.

Brilliant_brown [7]

Answer:

<h2>8.89 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{24}{2.7}  \\  = 8.88888...

We have the final answer as

<h3>8.89 g/mL</h3>

Hope this helps you

timama [110]

Answer:

Silver, 0.239 J/(g °C)

Explanation:

  • The heat change is related to specific heat as given by the formula;

Heat change = mass of substance × specific heat × change in temperature

  • Therefore; considering same amount of substance or equal masses and have the same initial temperature.
  • The change in temperature will be inversely proportional to the specific heat.
  • Therefore; the higher the specific heat lower the temperature change.
  • Hence,  the change in temperature will be highest for the substance with the lowest specific heat.

Therefore; the one that will increase in temperature the most is Silver
