I think it is Sedimentary rock, igneous is from fire/lava metamorphic is magma, so Sedimentary
False
Explanation:
A plant will die after being exposed to poison does not represent a physical change. A physical change is one that alters the physical state of matter and leads to no formation of new substances.
- The plant dies due to chemical changes in its structure.
- The poison will react with the chemicals in the system of the plant to produce new harmful ones.
- In a chemical change, new kind of substance forms in the plant and the change is irreversible.

Explanation:
Answer:
Chloroform= limiting reactant
0.209mol of CCl4 is formed
And 32.186g of CCl4 is formed
Explanation:
The equation of reaction
CHCl3 + Cl2= CCl4 + HCl
From the equation 1 mol of
CHCl3 reacts with 1mol Cl2 to yield 1mol of CCl4
From the question
25g of CHCl3 really with Cl2
Molar mass of CHCl3= 119.5
Molar mass of Cl2 = 71
Hence moles of CHCl3= 25/119.5 = 0.209mol
Moles of Cl2 = 25/71 = 0.352mol
Hence CHCl3 is the limiting reactant
Since 1 mole of CHCl3 gave 1mol of CCl4
It implies that 0.209moles of CHCl3 will also give 0.209mol of CCl4
Mass of CCl4 formed = moles× molar mass= 0.209×154= 32.186g
