Answer:
21%
Explanation:
We have a mass of 210.0 g of NaCl and a volume of 1000 mL. To find the percentage solution (m/V), we would divide % percentage solution.
Answer:
A. All of the answer choices are correct.
Explanation:
Giant sequoia trees
<u>They are long - living and the largest living organism on the planet Earth .</u>
They are majorly found in the western slopes of the Sierra Mountains present in the California .
These tress can grow to an average height of 50 to 85 meters , with diameter measuring 6 to 8 meters .
- They are also responsible for the generation of carbon dioxide via cellular respiration .
- It is the net sink of the carbon dioxide .
- It incorporates the carbon dioxide into the biomass .
<h2>T
he mass of a liquid substance affected after it boils : C it stays the same</h2>
Explanation:
Matter
Anything that occupies space and has mass .
The states of matter are :
Solids
Liquids
gases
Interconversion of state of matter
Solid ------liquid -----------Gas
(on heating ) (on heating )
- One state can be changed in to another by changing the condition of temperature , pressure etc .
- When liquid is boiled , it gets converted to gaseous form on heating .The heat supplied to change the state of matter is called latent heat .
- This latent heat , just helps in increasing the spaces between particles and decreasing the forces between them Hence we can say that it helps in changing the state .But it doesn't change the mass .Hence mass of substance remains the same .
- Similarly , gas -----> liquid -----> solid
(on cooling ) (on cooling )
Answer:
It would take 3.64 hours to travel.
Explanation:
200km with 55 per hour.
200 divided by 55 would equal 3.64.
I am dividing because to solve time would be distance/rate.
I hope this helps! :)
Answer:
d. a brittle solid.
Explanation:
Hello!
In this case, since cesium fluoride is widely known as an ionic compound due to the large electronegativity difference, it is possible to discard a. due to its crystalline structure, b. because conducting solids are metals, c. because ionic compounds are not likely to be gases and e. because even when it is soluble in water, the problem is not referring to an aqueous solution; therefore, the answer is d. a brittle solid.
Best regards!
