Answer: The spiny lobster belongs to the kingdom ANIMALIA while diatoms belongs to the kingdom PROTISTA.

Explanation:

There are different ways biologists have used to examine and describe million kinds of living organisms. To classify organisms into groups, biologist look for important features that are shared by a large variety of organisms. These features which should have similar origin, structure and position. Organisms with certain important features in common are then put together into one group.

In the hierarchy of living organisms, the largest group of organisms is the KINGDOM. There are five types of kingdoms in which organisms are grouped, these includes:

--> kingdom Monera

--> kingdom PROTISTA,

--> kingdom fungi,

--> kingdom plantae and,

--> kingdom ANIMALIA.

Kingdom PROTISTA: they are single-celled, motile or non-motile organisms that are made up of eucaryotic cells, that is,cell structure is complex with a definite nucleus. Member include the DIATOMS, amoeba and chlamydomonas.

Kingdom ANIMALIA: They are multiple-celled, motile organisms that feed on other organisms. Their cells have no cell walls. The members include the SPINY LOBSTER, corals,worms, snails and cows

Calcium carbide ( CaC2) reacts with water to produce acetylene (C2H2) as shown in the unbalanced reaction below: CaC2(s)+H2O(g)-
MaRussiya [10]
Answer:
46.3g H2O

Explanation:
start by balancing it: CaC2(s) + 2H2O(g) -> Ca(OH)2(s) + C2H2(g)

then use factor label method to solve

82.4g CaC2 x (1 mol CaC2/64.10g CaC2) x (2 mol H2O/1 mol CaC2) x (18.016g H2O/1 mol H20) = 46.3g H2O

calculate the number of moles of sulfuric acid that is contained in 250 mL of 8.500 M sulfuric acid solution
san4es73 [151]

Answer : The moles of H_2SO_4 are, 2.125 mole.

Explanation : Given,

Molarity of H_2SO_4 = 8.500 M

Volume of solution = 250 mL  = 0.250 L    (1 L = 1000 mL)

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

\text{Molarity}=\frac{\text{Moles of }H_2SO_4}{\text{Volume of solution (in L)}}

Now put all the given values in this formula, we get:

8.500M=\frac{\text{Moles of }H_2SO_4}{0.250L}

\text{Moles of }H_2SO_4=2.125mol

Therefore, the moles of H_2SO_4 are, 2.125 mole.
