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:
Time = 4.2273 seconds
Explanation:
The amount of the energy emitted by the microwave = 1100 J/s
It means that :
1100 J of the energy is emitted in 1 second
Also,
1 J of the energy is emitted in [tex]\frac {1}{1100}[tex] second
To calculate:
Time for emitting 4650 J of energy
Thus,
4650 J of the energy is emitted in [tex]\frac {1}{1100}\times 4650[tex] second
<u>Time = 4.2273 seconds</u>
Answer:
3 mole O2
Explanation:
Need balanced equation first: O2 + 2SO2 --> 2SO3
assuming SO2 is in excess,
1.5 mol O2 (2moles SO3/1mole O2) = 3 mole O2
Answer:
no
Explanation:
no, because it will make me sick. And my doctor said that just because something is brown and squishy it isn't chocolate.
Answer:
C
Explanation:
This is because The polar group consist of 10 amino acids, two are negatively charged that is aspartic acid and glutamic acid, 3 have a positive charge - arginine, lysine and histidine, and 5 are uncharged
