Neutral Magnesium atom

Explanation:

From the given description of the atom, one can infer that this atom is a neutral atom.

In a neutral atom, the number of protons and neutrons are the same.

 Atomic number = 12

  Mass number = 25

This atom is Magnesium.

   Magnesium has an atomic number of 12 from the periodic table.

Number of protons = 12 = atomic number

 Number of electrons = 12(for neutral atoms, atomic number is same as number of electrons).

  Number of neutrons = mass number - atomic number = 25-12 = 13.

compare 51.5 hectograms to 51500 decigrams. How do each of these values compare to a gram, and which represents a larger mass?
Olin [163]
These values when compared seem to be the same. They are equal. If we convert them to the same units, they results to the value which is:
 
51.5 Hectograms = 5100 Grams

51,500 Decigrams = 5100 Grams


Hope this answers the question. Have  a nice day.

An ice cube in a glass of water is pushed to the bottom of the glass and held there with a straw. Consequently, the buoyant forc
blagie [28]

Answer:d

Explanation:

Given

Initially, the ice cube is floating over the water

When the cube is pressed to touch the bottom, it is submerged fully

Therefore more buoyant force is acting on it

At first, a part of the volume is submerged in the water, so the buoyant force is less, but as the entire cube is immersed in the water, the buoyant force increases.
