Farly scientists performed experiments regarding mass and products for many years, but had difficulty demonstrating that mass was
conserved. This changed when they conducted these experiments
under specific conditions. What condition was this? Refer to
Paragraph 4.
А
They conducted experiments with specific gases.
B
They conducted experiments with specific types of wood.
с
They created scales that gave more precise measurements.
D
The experiments were conducted in sealed containers

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

consider the reaction below.
