You can not hear sound in vacuumed places like space. Wherever there is a high altitude, it makes it harder to hear sound and harder to breathe. Sound travels best in solids. Hope that helps a little bit.

What is the overall reaction order for this rate law: rate= k[A][B]?

nika2105 [10]

The over all order of the reaction with the rate law of rate=k[A][B] is 2 since the exponent for [A] is 1 and the exponent for [B] is 1 and 1+1=2.

for example the order for the rate law rate=[A]²[B] is 3 since 2+1=3 and the order for a rate law of rate=[A]²[B]³ the order would be 5 since 2+3=5.

I hope this helps. Let me know if anything is unclear.

How is the ocean important to human survival? restate the question

Aneli [31]

Answer:

How is the ocean important to human survival? The air we breathe: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns

Which sequence represents the relationship between temperature and volume as explained by the kinetic-molecular

Mars2501 [29]

Explanation:

The kinetic energy of a gas molecule is given by :

$E=\dfrac{3}{2}kT\\\\\implies E\propto T$

It means, whenever the temperature of gas is increased, its kinetic energy will increase and the space between the particles gets increase. So, the space in which particles can collide with each other increases i.e. its volume gets high.

Hence, the correct option is (A). "higher temperature more kinetic energy → more space between particles – higher volume".

Whats the equation and answer for these two separate questions!!

Lena [83]

Answer:

3).

$time = \frac{distance}{speed} \\ time = \frac{225}{3} \\ time = 75 \: s$

4).

$speed = \frac{distance}{time} \\ speed = \frac{110}{55} \\ speed = 2 \: {ms}^{ - 1}$
