Answer:
Stalagmites
Sinkholes
Stalacites
Explanation:
These features are created because the ground water dissolves solid rocks and move the solid rocks, dissolve solutions beneath the ground water gradually and therefore enlarging the cracks, which eventually form a cave. Ground water carries minerals which are then deposited and can form stalagmites or stalactites. If a stalactite and stalagmite combine together, they usually form a column.
Answer: 42 hours
Explanation:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains number of particles.
We know that:
Charge on 1 electron =
Charge on 1 mole of electrons =
According to stoichiometry:
1 mole of electrons deposit = 23 g of sodium
i.e 96500 C of electricity deposit = 23 g of sodium
Thus 23 g of sodium is deposited by = 96500 C of electricity
of sodium is deposited by = C of electricity
To calculate the time required, we use the equation:
where,
I = current passed =
q = total charge =
t = time in secods = ?
Putting values in above equation, we get:
Thus 42 hours are required.
Answer:
The most common chemical properties are flammability and reactivity. Flammability looks very similar to a word that many of you have seen before: flame. In this case, flammability is the ability of a substance to burn or better yet, how easily something burns.
Explanation:
It depends on the habitat if it was a habitat by a lake or creek it would affect the inhabitant's access to water.
The Law of Conservation of Matter states that matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same.
