B. Organic sedimentary rock C. Chemical sedimentary rock
6. What type of sedimentary rock is fossiliferous limestone?
A. Clastic sedimentary rock
B. Organic sedimentary rock
C. Chemical sedimentary rock

A. Clastic sedimentary rocks

Explanation:

Chemical form = CaCO3

Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Examples include: breccia, conglomerate, sandstone, siltstone, and shale.

Hope this helps! :)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

i think that the answer is c
