C is the correct answer.a buffer reacts with the added acid or base which can produce H+ or hydroxide ion,or a kind of removing H+ or hydroxide added to solution.remember that buffers don't prevent additional acid or base from reacting,they react with the additional themselves.the A and D are completely wrong.
Answer: is the correct equation for beta decay.
Explanation:
When a beta particle, that is, is emitted in a radioactive decay then it is known as beta decay.
Therefore, beta decay of Polonium-218 is as follows.
Therefore, we can conclude that is the correct equation for the given beta decay.
Answer:
A. 2.4 x 10¹⁴ J
Explanation:
m (mass) = 2.7 x 10⁻³ kg
c = 3.0 x 10⁸ m/s
Plug these numbers into the equation E=mc²
E=mc²
E= (2.7 x 10⁻³)(3.0 x 10⁸)²
E= 2.43 x 10¹⁴
So, the answer is A. 2.4 x 10¹⁴ J.
Independent is the variable that you change
Dependent is the thing you measure
