This is how you would do it. set up the rxn. balance, in this case you didn't need to. make a grid and cancel out units.
Answer:
Organisms that do not live in water would either have to adapt, or they would die. Other water organisms might move into the ecosystem. Diseases that are waterborne might make a surge.
Explanation:
For the titration we use the equation,
M₁V₁ = M₂V₂
where M is molarity and V is volume. Substituting the known values,
(0.15 M)(43.2 mL) = (2)(M₂)(20.5 mL)
We multiply the right term by 2 because of the number of H+ in H2SO4. Calculating for M₂ will give us 0.158 M. Thus, the answer is approximately 0.16M.
The rock cycle is referred to as cycle because it repeats over and over again. The definition of cycle is a series of events that are regularly related in the same order. So with the rock cycle they stay in the same order and repeat.
Hope this helps :)
