Answer:
Explanation:
Filtration followed by evaporation:
To separate the mixture of sand and sugar, it is best to use the separation technique of filtration then evaporation.
Pour the water into the mixture. The sugar will dissolve with time in the water. Sand is made up of quartz and does not dissolve in water.
After the dissolution, filter the solution to separate the sand using a filter paper.
Dry the sand thereafter then proceed to evaporate the sugar with water solution. Evaporation will turn water into vapor and the sugar crystals will be left behind.
Answer:
- Reduced biodiversity
- Health problems from drinking the water
- Diseases
The number of protons defines what element it is and also determines the chemical behavior of the element.
I believe it is the third choice from the left because it is 3D and has the "sticks", unlike the space-filling model to the left of it. Hope this helped!
Answer:
V = 4480.56 cm3
Explanation:
Data Given
Length “l” = 14 inches
Hight “h” = 7 inches
Width “w” = 1.5 feet
Volume= “V”
Solution:
Formula to Use
V= l . w. h
Note: here we have to values in the same unit
So the Length “l” and Hight “h” both are in inches but the width is in feet
So we changes the feet into inches
1 foot = 12 inches
1.5 feet = 12 x 1.5
1.5 feet = 18 inches
So width is 18 inches
Now putting the values in formula
V = l . w. h
V = 14 . 18 . 7
V = 1764 inch
You can convert inches to cm
1 inch = 2.54 cm
So 1764 inches = 2.54 x 1764
1764 inches = 4480.56 cm3
So
V = 4480.56 cm3
