If a sample of iron with a density of 7.80 g/cm3 displaces 75.0 mL of water when placed in a beaker, what is its mass?

Answers

1 mL = 1 cm³

75.0 mL = 75.0 cm³

Density = mass / volume

7.80 = mass / 75.0

mass = 7.80 x 75.0

mass = 585 g

hope this helps!

What are the three elements found in a molecule of calcium carbonate? Give their atomic numbers and chemical symbols. How many atoms of each are found in one molecule of calcium carbonate?

Answers

Calcium carbonate is CaCO3.
So there is calcium, symbol is Ca and an atomic number of 20.
Carbon: symbol is C and an atomic number of 6.
Oxygen: symbol is O and an atomic number of 8.
In one molecule of CaCO3, there is one atom of Ca, one atom of C, and three atoms of O as shown by the subscript next to O in the formula. There are no other subscripts to indicate more than one atom of the other elements, so there is only one atom of the other two elements

Which of the following mixture types can be filtered to remove solute? (1 point) suspensions only colloids only suspensions and colloids suspensions and solutions

Answers

The correct answer is suspensions only. The suspension is a heterogeneous mixture that contains solid particles that are largely enough to undergo sedimentation. Usually, these particles are about one micrometer which makes these solute to be very easy to be free from their solvent and be filtered.

The answer to your question is

suspensions only

Electrons are emitted from a conductor when the conductor is A. bombarded by high-speed electrons.
B. cooled rapidly.
C. subjected to a small voltage.
D. exposed to weak light.

Answers

Answer:

A. bombarded by high-speed electrons.

Explanation:

Conductors are materials that allows current to pass through them.

However, the flow of current is actually the flow of electrons in the opposite direction.

When a conductor is bombarded by by high-speed electrons, the high speed electrons will repel the electrons in the conductor (in electromagnetism, like charges repel) thus giving them the required kinetic energy to leave the surface of the conductor.
A. bombarded by high-speed electrons.
Electrons are emitted from a conductor when the conductor is bombarded by high-speed electrons. This is because the electrons that are already present in the object especially when the object receiver is a metal, water or any object able to conduce electricity, the electrons in these objects are in form of potential energy and when other electrons are in contact with them they move and thus being from potential to kinetic.
