<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.
The presence of H3O+ is the hydronium ion, and one definition of an acid is something that donates a proton (H+). HCl in this case does just that. Basic solution forming with NaOH and water: ... NaOH + H2O ==>Na+ + OH- so it donates or produces OH- ions, thus making a basic solution
Answer:
This is due to the water moisture present in the recovered sample.
Explanation:
The total amount of material recovered isn’t meant to weigh more than the original sample. However when this happens then it means there is the presence of water moisture in the recovered sample.
The recovered samples however needs to be heated to make it dry and eliminate the water moisture through evaporation.
Answer:
The answer is
<h2>6.54 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of ball = 8.5 g
density = 1.3 g/mL
It's volume is
We have the final answer as
<h3>6.54 mL</h3>
Hope this helps you
