Cane toads are native to Central and South America and to Mexico. In the 1930s, people brought cane toads to Florida and Australia to consume beetles that cause damage to sugar crops. While the cane toads have been successful at reducing beetle populations, they have also had unforeseen impacts as well, such as being toxic to local predators.

A community in Florida wants to minimize the impact that cane toads have on the local ecosystem. Which of the following should they identify as part of defining the problem?
A.
the predator populations that eat cane toads
B.
solutions that are likely to be effective for controlling the cane toad population
C.
methods that have been used to control cane toads in Australia
D.
ways to raise money to support their efforts

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

thats a little if u want the answer just look it up on google thats what i do haha : )

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
