Answer:
5
Explanation:
if you do 17/3.45
=4.9 but if you round it up to the nearest whole number 5.
3.45*5=17.25
it equals to 17.25
The correct response would be C. Mass cannot be created nor destroyed in a chemical reaction.
Answer:
1.The reaction that opposes the change
Explanation:
Consider the reaction;
A + B ⇄ C + D
If a constraint such as a change in temperature, pressure or volume is imposed on this chemical system in dynamic equilibrium, the equilibrium position will shift so as to annul the constraint.
This shift in the equilibrium position will favour either the forward or reverse reaction depending on the type of constraint imposed on the system.
Hence, If a chemical system is at equilibrium, any change in the system will always result in an increase of the reaction that opposes the change.
Phase transition is when a substance changes from a solid, liquid, or gas state to a different state. Every element and substance can transition from one phase to another at a specific combination of temperature and pressure.
Answer:
Hexane
Explanation:
This is a simple Alkane with six cabrons therefore the prefix "Hex-" is applied. Since the molecule has no double bonds it will have the ending "-ane"
