Answer:
The answer is a I think
Explanation:
I think this because it has all of the shapes that are included in the other ones
Answer: 
Explanation:
Heat of combustion is the amount of heat released when 1 mole of the compound is completely burnt in the presence of oxygen.
To calculate the moles, we use the equation:
Thus 
of sucrose releases = 916.6 J of heat
1 mole of sucrose releases =
of heat
Thus ∆H value for the combustion reaction is
The answer is C.
This can be concluded by looking at the other answers and eliminating them one-by-one.
Managing (Or conserving) a natural resource means to sustain it and use it as efficiently as possible.
With this in mind, we can look and eliminate certain answers.
A is incorrect because driving a car uses gas, a natural resource. By using as much gas as possible, the resource would be wasted instead of conserved.
B is incorrect because water is a natural resource. Once again, by using this, it's wasted where it could be conserved.
C is correct because planting trees would conserve the resource; by consistently planting trees where they're cut, the chances of running out of wood decrease.
D is incorrect because both the water and the creatures that live inside it are natural resources. By dumping toxic waste, these resources are wasted where it could be conserved.
Hope this helped you! :)
