just subrracted them and find out whats m
Explanation:
Answer:
The solution is always homogeneous mixture and transparent through which the light can travel. The mixture of water and sugar is a solution because sugar is soluble in water and form homogeneous mixture while the sand can not dissolve in water and sand particles scatter the light.
Explanation:
Solution:
"The solution is always homogeneous mixture and transparent through which the light can travel"
The mixture of water and sugar is a solution because sugar is soluble in water and form homogeneous mixture. The solubility of sugar is high as compared to the sand in water because the negative and positive ends of sucrose easily dissolve into the polar solvent i.e, water
Suspension:
"Suspension is the heterogeneous mixture, in which the solute particles settle down but does not dissolve"
The mixture of water and sand is suspension. The sand can not dissolve in water because it is mostly consist of quartz. The nonpolar covalent bonds of sand are too strong and cannot be break by water molecules.
Answer:
You need to count all the atoms on each side of the chemical equation. once you know how many of each type of atom you have,you can only change the coefficient. (the numbers in front of the atoms or compounds
Answer:
It becomes negative
Explanation:
protons carry a positive charge
neutrons carry a neutral charge
electrons carry a negative charge
if we add 2 more electrons, the charge of the ion becomes negative
thank you.
Ahh. The chain reaction.
.
You know when you are surfing the web, your parents tell you, or you surf the web, that you see some things like "STOP GLOBAL WARMING?"
.
Yep, I have, at least.
.
Well, let's see about the chain reaction...
.
You see, where does our energy come from?
.
Yes, windmills and solar cells...
.
but also nuclear and power plants, no?
.
The power plants emit carbon dioxide that contribute to global warming.
.
Now, cars do the same. One car may not seems like a lot of carbon dioxide...
.
.
But... this many cars multiplied by 9 trillion times 9 trillion and much more... is...

Well, you know the difference.
.
They contribute to global warming over a period of time, slowly, because they emit carbon monoxide/dioxide.
