Answer:
CaCO3 exoskeleton dissolves in acidic water
Explanation:
The increasing CO2 level makes the ocean water acidic and hence reduces the pH. In such acidic environment, marine organism that produce calcium carbonate shells or skeletons are negatively affected. Coral reefs and coralline algae abilities to produce skeleton also reduces.
Calcium carbonate dissolves in acid. Thus, the more acidic the ocean water is the faster and easier it is to dissolve the exoskeleton and shell of marine organisms made up of calcium carbonate
My thought would be B) gases.
I could be wrong but that's what i'd say
Explanation:
from the equation 1 mole of O2 will give 2 moles of H2O then 6.0 moles of O2 will give x
6.0*2 moles/ 1 mole
= 12 moles
this implies that, 6.0 moles of O2 will give = 12 moles of water
Q = mcΔT = (4.00 g)(0.129 J/g•°C)(40.85 °C - 0.85 °C)
Q = 20.6 J of energy was involved (more specifically, 20.6 J of heat energy was absorbed from the surroundings by the sample of solid gold).
Subsidy
A price support is a type of subsidy. It seems that this is not given in
the choices. However, subsidy is a form of monetary or financial support which
is provided by a local or state sector. It aims to provide economic and social
stability and development. Hence, subsidy encompasses various types of support
funded by either government or non-government offices. It can be given in form
of either direct (money, incentives and etc.) or indirect (insurance,
write-offs and etc.) in procedures.
