The first step is to establish a goal and write it down. This adds commitment and you are declaring your intentions.
The second step is write down your daily plan of action. A plan without action is as useless if you had never written the goal at all.
The third step is to share your goal with someone who will hold you accountable. They can share your victories , failures, and provide encouragement.
The final step is to act on that plan. You must take action now that you have all the tools.
Answer:
The answer is (H30+) =3,55e-8M and (OH-)=2,82e-7M
Explanation:
We use the formulas:
pH= - log(H30+) and Kwater=(H30+)x(OH-)
pH= - log(H30+) ----< (H30+)= antilog- pH=antilog- 7,45=3,55E-8M
Kwater=(H30+)x(OH-)
(OH-)=Kwater/(H30+)= 1,00e-14/3,55e-8 = 2,82e-7
Answer:
2016 km
Explanation:
The escape velocity from Earth's surface is
.
We need to find how many kilometers would a rocket travel in three minutes. It is a concept based on the definition of speed of an object.
Speed = distance per unit time
1 hour = 60 minutes
⇒ 3 minutes = 0.05 hour
1 m/s = 3.6 km/h
11200 m/s = 40320 km/h
So,

Hence, a rocket will travel 2016 km in 3 minutes.
D is the answer, I believe.
An isolated system is one that allows neither heat or matter to enter or exit, and since the liquid remained the same temperature, one can conclude that neither energy nor matter is passing through.
