I think it's B. Independent Variable. i hope i've helped
Answer:
It would take 3.64 hours to travel.
Explanation:
200km with 55 per hour.
200 divided by 55 would equal 3.64.
I am dividing because to solve time would be distance/rate.
I hope this helps! :)
Answer:
pH = 1.30
Explanation:
The reaction that would take place between HCl and NaOH is:
In this problem, the 0.1 moles of NaOH would react with 0.1 moles of HCl, <u>leaving 0.1 moles of HCl unreacted</u>.
These 0.1 HCl moles are dissolved in 2 liters, thus the concentration of H⁺ species is:
- [H⁺] = 0.1 mol / 2 L =0.05 M
Finally we <u>calculate the pH</u>:
Answer:
<h2>When heat are heated,the average kinetic energy of the molecules increases. This means that more molecules are moving faster and hitting each other with more energy.If more molecules hit each other with enough energy to react, then the rate of reaction increases </h2>
