The molar mass of sodium is 22.99 ㅤ ㅤ ㅤ 22.99 (28) = 643.72 mol now multiply by avogrados number to find the number of atoms. ㅤ ㅤ ㅤ 643.72 (6.022 x 10^23) = 3.88 x 10^26 number of atoms
Answer:
Explanation:
Given that:-
![rate = k[NH_4^+][NO_2^-]](https://tex.z-dn.net/?f=rate%20%3D%20k%5BNH_4%5E%2B%5D%5BNO_2%5E-%5D)
k = 
![[NH_4^+]=0.301\ M](https://tex.z-dn.net/?f=%5BNH_4%5E%2B%5D%3D0.301%5C%20M)
![[NO_2^-]=0.160\ M](https://tex.z-dn.net/?f=%5BNO_2%5E-%5D%3D0.160%5C%20M)
So,
<u>
is the rate of the reaction at that temperature if [NH4+] = 0.301 M and [NO2−] = 0.160 M.</u>
Answer:
NASA uses rockets to launch astronauts and supplies to the International Space Station. Launching a rocket relies on Newton's Third Law of Motion. A rocket engine produces thrust through action and reaction. The engine produces hot exhaust gases which flow out of the back of the engine.

Answer:
A banana, like most other lifeforms, is about 70% water, and all the potassium it contains already exists in the form of K+ ions dissolved in water. Which is why bananas do not explode in water, or spontaneously combust.
