Answer: Calcium Sulphate Hemihydrate
The compound of calcium which is used for plastering of fractured bones is Plaster of Paris. It is also called as Calcium Sulphate Hemihydrate.
it is a that is the correct answer
A. LITTORAL ZONE is a freshwater ecosystem that is home to rooted plants.
Littoral zone is the shallow area of a lake, pond, river or ocean. This is the area where mangroves grow.
Some counties and water district identify littoral zones so that these zone will be planted with native plants. This is done for the purpose of having the plants purify the water and maintain a balanced ecosystems.
THey can move around each other instead of just vibrating in place like solid prticles.
We can express the rate equation in this form:
-r = k A^n B^m
where -r is the rate
k is the rate constant,
A is the concentration of CH3Cl
n is the order with respect to CH3Cl
B is the concentration of H2O
m is the order with respect to H2O
We can solve this by trial and error or by calculus. The first method is easier. The rate constant does not depend on the concentration of the reactant. Assume values of n and m and solve for k in each experiment. The only option that gives really close values of k in each experiment is:
