Why are the marked lines on a beaker like this useful for measuring the volume of a liquid? A liquid maintains its shape in the

beaker, so the beaker can measure the liquid’s height, and the height cubed equals the liquid’s volume. A liquid conforms to the circular area of the beaker, and this area multiplied by the liquid’s height equals its volume. A liquid is usually made of neutral atoms, and the beaker does not add or remove energy from the atoms, thereby preventing ionization. A liquid is compressible, but since the beaker does not have a top on it, the liquid will maintain its same volume THE ANSWER IS (B)

Answer : Option B) <span>A liquid conforms to the circular area of the beaker, and this area multiplied by the liquid’s height equals its volume.

Explanation : When a liquid is poured into a beaker the liquid takes the internal shape of the beaker which is circular in shape, according to the markings on the beaker one can measure approx quantity of fluid required and perform the experiment. The area of circular of the beaker when multiplied with height of liquid gives the total volumes of fluid present in it.

If a question cannot be tested and observed, it cannot be answered with science. (2 points) True or False?
boyakko [2]

Answer:

True

Explanation:

If a question cannot be tested and observed, it cannot simply be answered by science.

Science works with observable and testable ideas and not on metaphysics.

  • Science presents a methodical approach into investigating phenomenon and answering likely questions in a logical manner.
  • The body of facts and data gathered through observations and tests are used to ramify the conclusion of a scientific study.
  • Without such, it is impossible to do the work of science.

Here is the electron configuration for Magnesium. How many total electrons are in the 2nd energy level?
balandron [24]

Answer:

8 electrons

Explanation:

Magnesium is present on group 2.

It has 2 valence electrons.

Electronic configuration of magnesium:

Mg₁₂ = 1s² 2s² 2p⁶ 3s²

1st energy level contain 2 electrons.(1s²)

2nd energy  level contain 8 electrons. (2s² 2p⁶)

3rd energy level contain 2 electrons. (3s²)

3rs energy level of magnesium is called valence shell. It contain two valance electrons. Magnesium can easily donate its two valance electrons and get stable electronic configuration.

It react with halogens and form salt. For example,

Mg + Cl₂   →   MgCl₂
