Answer:
You can see that it is an endothermic reaction or heat is being absorbed for the change from magnesium to magnesium oxide. So it is an endothermic reaction. So these are the four reasons why we can say that burning of magnesium ribbon in the air is considered a chemical change.
Explanation:
hope it help
The formula of the molarity, M is: M = number of moles of solute / Volume of solution in liters.
Here number of moles of solute is 7.0 and volume of solution in liters = 569 mL / 1000 mL/L = 0.569 L
M = 7.0 moles / 0.569 liters = 12.3 M
Answer: 12.3 M
Low air pressure cause it was on my test last year
It is not used up in a reaction. This is because a catalyst is added to a reaction in order to speed it up, but only for that—it doesn’t react with anything, so it isn’t a product nor reactant of any reaction
The equation is balanced and the reaction type is synthesis btw. hope that helps!
