Describe what happened when sodium chloride (salt) was placed in water in the video What happens when stuff dissolves?"

Chemistry
1 answer:
Sonja [21]2 years ago
6 0

Answer:

-

Explanation:

Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.

Calculate the number of atoms in 3mol helium
OleMash [197]
 <span>The chemical formula of Helium is He. 

Question 1 : 

Given n = 1.11 x 10^-6 

To get no. of the particle, 
No of particle = no. of mole x Avogadro Constant 
p = n x NA 

1 mol of Helium = 6.02 x 10^23 

No of atoms = (6.02 x 10^23) x (1.11 x 10^-6) 
= 6.66 x 10^17 

................................ 

Question 2 : 

Given p = 4.29x10^21 

p = n x NA 
4.29 x 10^21 = n x (6.02 x 10^23) 
(4.29 x 10^21) / (6.02 x 10^23) = n 
n = Approximately 7.126 x 10^-3 

Hope the answer is right :)</span>

A squirrel ran 20 meters along the fence at a constant speed for 10
Black_prince [1.1K]

Answer:

It's D

Explanation:

Sorry for the late answer. Since the squirrel ran constant speed for 10 seconds and it ran 20 meters the first point would be at (10,20) then since it stopped to rest for 15 seconds the next point would be (25,20) finally since it ran another 30 meters for 15 more seconds the next point would be at (40,50). Sorry if the answer isn't the best, i'm bad at explaining ;w;

Which process transfers heat from inside earth to its surface
Over [174]
Answer is: thermal conduction.
<span>Thermal conduction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.
</span><span>The thermal energy of that core is transferred to the surface of the Earth and lower levels of the oceans by conduction. Water in lakes and oceans transfers heat to the surface by convection.</span>
