First off, we can find the volume that need to be filled:
2-1.25
=0.75L
Asbthe unit is still in Litres,we need to converge it to mL.
1L = 1000mL
mL needed:
=0.75×1000
=750mL
Therefore the answer is 750mL.
Hope it helps!
Salinity and conductivity measure the water's ability to conduct electricity, which provides a measure of what is dissolved in water. In the SWMP data, a higher conductivity value indicates that there are more chemicals dissolved in the water. ... Ions increase the water's ability to conduct electricity.
Elements are substances that cannot be broken further down by chemical (or physical, for that matter) means. Sodium, tungsten, and iodine are all examples of chemical elements.
The correct answer is C, chemical change.
