Answer:
1- Option A = Sink
2- Option B = Float
Explanation:
1- If an object’s density is greater than 1.00 g/mL, it will sink in water.
For example, the density of aluminum is 2.7g/cm³. That is why it will sink in water.
2- If an object’s density is less than 1.00 g/mL, it will float in water.
For example, the density of oak is 0.7 g/cm³. That is why oak will float in water.
3- Given data:
Mass, m = 50 g
Volume, v = 10 cm3 ( 1ml = 1cm3)
Formula of density :
Density = mass/ volume
d = m/v
d = 50g/10cm3
d = 5 g/cm3
Im doing the test now and i think it's 140. I dont really know how to use the chart and dont know if im correct or not, but Im assuming the "grams of solute per 100g H2O" means that at whatever corresponding point between the temperature and chemical line on the graph has 100g H2O. So if you find 90 degrees on the graph and go up to the NH4Cl line, your Y Axis will say 70. But since the "grams of solute per 100g H2O" this means to satisfy the requirements of having 200g of water, you must double the 70 to 140. (This is my best guess, just as lost as you but im trying)
The answer is: Soft solid rock
Answer:
A) habitat
Explanation:
a habitat is essentially the organisms "home". also known as a "niche"
Answer: The answer is C. replacement
This would be an example of a replacement type of reaction. As the iron is replaced with the aluminum in the reaction.
