It represents an observation and he formed a hypothesis to explain the observation.
Answer:
What you need to know before I explain is how to add percents onto numbers. What I'm saying is what and how to do 6.4% x 1500
1. You can't do a percent and number together, that's impossible
What you can do is convert the percent (6.4%) into a decimal
2. 6.4% is equivalent to 6.4/100, which is equivalent to 0.064
3. Now, you multiply 0.064 x 1500
You will notice, hopefully, that you have a number smaller than 1500, but do not panic, you are on the right track!
4. Using the number you got, add that to 1500, and there's your total!
But, if you want only the tax, keep that small number you started off with!
Explanation:
Answer:
Fewer bubbles will be produced because of fewer collisions of reactant molecules
Explanation:
As the solid dissolves into the solution after the liquid has been vigorously bubbled, if the temperature of the liquid is reduced a little, what will happen is that fewer bubbles will be produced as a result of lesser amount of collisions occurring between the reactant molecules
Heres the answer to your question
