Answer:
yes. you need blood to live. if it runs low then your life starts to disappear just like the river would if the water started to run low in it
The problem ask to show the reaction between the two elements which is calcium and oxygen to form an ionic compound. Base on the data that Calcium has n electronic compound of 2.8.8.2 and oxygen has 2.6, the reaction of the both is to add 2 electron in Calcium and also in the oxygen because both of the m has 2 extra electron
Answer:
Substance 4
Explanation:
Density is defined as mass per unit volume. A substance floats in another when its density is less than that of the substance on which it floats.
If an object is immersed in a denser liquid, it will sink
Since the density of water is 1 g/cm^3, any substance whose density is less than that of water will float in it.
If we look at the table, substance 4 has a density of 0.5g/cm^3. Hence, substance 4 is expected to float in water.
Answer:
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.
This is a false statement. Graduated cylinders measure volume, yes, but i'm afraid that beakers do not.
Hope this helps!
