50.4g of magnesium metal is added to a graduated cylinder containing 30ml of water. the water level rises to the 85ml mark, from this information, calculate the density of the magnesium metal?​

Answers

Answer 1
Density= mass divided my volume.
To get the volume of the magnesium (85-30) which is the volume of the magnesium and water - the volume of water only
The mass is given so
50.4\55 the density 0.9 g per ml

A. Atoms would lose their electrons if they didn't form bonds.
B. Atoms could not exist without a full octet of valence electrons.
C. Atoms are often more stable when bonded to other atoms.
D. Atoms form bonds to make the neutrons more stable.

Answers

Answer:

Atoms are often more stable when bonded to other atoms

Explanation:

Like for example let's say ionic bonds..... Since one atom has to lose specific electrons to be stable and the other needs the electrons from the other atom to be stable.....

Answer:

C. Atoms are often more stable when bonded to other atoms

Explanation:

bonding is the joining of two atoms of the same or different elements to form a molecule with the help of forces of attraction.when the atoms join they gain stable electronic configuration .

Explain in words or using your diagrams how beryllium atoms would react with fluorine atoms.
Show clearly the outcome of the reaction and state the formula.

Answers

Explanation:

To delineate the the nature of the bonds that would be formed between the two elements, let us first write the electronic configuration of the two species;

  Be  = 2, 2

  F  = 2, 7

 Beryllium is a metal with two valence electrons whereas fluorine is a halogen with seven valence electrons.

When Be loses two electrons it becomes isoelectronic with He;

                 Be →  Be²⁺ + 2e⁻  

Also, when fluorine gains  an electron, it becomes isoelectronic with Ne;

               F  + e⁻ →  F⁻

This loss and gain of electrons between the two elements creates an electrostatic attraction them and they enter into an electrovalent bond.

      Hence;

           Be²⁺  + 2F⁻ → BeF₂

If an object has a volume of 3 cm3 and has a density of 9 g/cm3. What is the mass of the object?

a student places a small stone with a mass of 5 g into a graduated cylinder containing 50 mL of water. With the stone in the graduated cylinder, the water rises to 75 mL. What is the density of the stone?

Answers

Answer:

The answer is 0.2 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

volume = final volume of water - initial volume of water

volume = 75 - 50 = 25 mL

We have

[tex]density = \frac{5}{25} = \frac{1}{5} \\ [/tex]

We have the final answer as

0.2 g/mL

what does buffer do?? (Chemistry)​

Answers

A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges. Buffer solutions have a working pH range and capacity which dictate how much acid/base can be neutralized before pH changes, and the amount by which it will change.

Answer:

C, It resists a change in pH when H+ or OH is added to a solution.

The ionization energies for removing successive electrons from sodium are 496 kJ/mol, 4562 kJ/mol,
6912 kJ/mol, and 9544 kJ/mol. The great jump in ionization energy after the first electron is removed
indicates that
Select one:
O a. sodium has four or five electrons.
O b. the atomic radius has increased.
c. a d-electron has been removed.
d. the noble gas configuration has been reached.

Answers

Answer:

D

Explanation:

The high jump of ionization energy indicates that we are trying to remove electron from noble gas configuration state.

The ionization energy data specifies that the Elements are from group 1 at period 3 or greater.

Removing the first electron require 496 kJ and the second ionization energy jump significantly due to the removal of electron from the noble gas configuration which is logical because electron try to maintain the especially stable state.

There are five objects (a pink object, a yellow object, a white object, a gray object, and a violet object). Each object has a different mass (28.7 g, 41.6 g, 8.7 g, 30.4 g, and 76.9 g) and a different volume (11.6 cubic cm, 57.4 cubic cm, 14.9 cubic cm, 29 cubic cm, and 57 cubic cm). The masses and volumes listed above are not in any particular order, they are listed randomly. Use the clues below to figure out the mass, volume, and density of each object. Construct a table to display your data. 1. The volume of the yellow object is not 29 cubic cm and it is also not 57.4 cubic cm. 2. The white object has a greater mass than the pink object. 3. The gray object has a density of 1.349 grams per cubic cm and a mass of 76.9 g. 4. The density of water is 1.0 gram per cubic cm. If the white object was placed in water, it would sink. 5. The density of water is 1.0 gram per cubic cm. If the yellow object was placed in water, it would float. 6. The density of aluminum is 2.7 grams per cubic cm. The violet object is more dense than aluminum. 7. One object has a volume of 57.4 cubic cm and a density of 0.5 grams per cubic cm. 8. The volume of the violet object is not 11.6 cubic
