11. Group 2 on the periodic table corresponds to what family of elements?

Answer:

I looked it up and it said 6.214

Answer:

Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.

Explanation:

The groups in the periodic table that want to gain electrons are groups; 15, 16 and 17. The members of these groups are mostly nonmetals.

The periodic table is composed of 18 groups and 8 periods of elements. Groups 1 - 13 are metals while groups 15 -18 are nonmetals. Group 14 consists of a mixture of metals and nonmetals.

The nonmetals usually accept electrons while metals electrons easily donate electrons. Elements of group 18 neither receive nor donate electrons because they have a complete octet.

Nonmetals of groups 15 -17 gain electrons easily.

Answer:

The amount of mass and matter in all the transformations of the clay ball will remain the same or constant

Explanation:

From the  law of conservation of mass we have, for an enclosed system to and from which there is no transfer of matter or energy, mass cannot be created nor destroyed, and remains constant at the given value, but the matter which make up the mass can be changed into different forms

Therefore, the clay ball can be transformed into different shapes and will still posses the same initial mass before the transformation, provided there are no transfer of matter or energy from the clay ball system.

Answer:

The advantage of the compound light microscope over the dissecting microscope is the magnification power of the telescope. Compound light microscope magnifies from 40x up to 1,000x while dissecting microscope magnifies up to 40 x only. In this regard, more magnification power is advantageous to view smaller objects.

Answer:

the new volume is 1.35L

Explanation:

The computation of the new volume in the case when the temperature rises to 45 degrees is shown below:

GIven that

Volume = 1.25L

And, the temperature is 22 degrees celsius

So, [tex]T_1[/tex] = (275 + 22)k

= 297 k

Now

[tex]T_2[/tex] = (275 + 45)k

= 320 k

Now as it is a constant pressure

So, the new volume is

[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2} \\\\V_2 = \frac{V_1}{T_1}\times T_2 \\\\= \frac{1.25}{297}\times 320[/tex]

= 1.35L

hence, the new volume is 1.35L

Magnet

Durability and heaviness.(texture)

Explanation:

Magnet can be use to separate Aluminum from mixture of steel and aluminum.

Though aluminum and steel look alike but magnet can be use to separate it.

If the can attract the magnet or magnet stick to the can, it is a steel can. Aluminum does not stick to magnet.

A mixture of Aluminum and tin can also be separated by magnet.

Tin attract magnet but tin is more durable, heavy and does not corrode easily.

When u touch the three cans, tin is heavy and durable.

Answer:

4.9 m^3

Explanation:

volume= 1.0 x 3.25 x 1.50= 4.875 -> 4.9m^3

Answer:

1.12 g.

Explanation:

From the question given above, the following were obtained obtained:

Volume (V) of metal = 2.3 cm³

Density (D) of metal = 0.486 g/cm³

Mass (m) of metal =..?

The density of a material is simply defined as the mass of the material per unit volume of the material. Mathematically, it is expressed as:

Density (D) = mass (m) / volume (V)

D = m/V

With the above formula, we can easily calculate the mass of the metal as shown below:

Volume (V) of metal = 2.3 cm³

Density (D) of metal = 0.486 g/cm³

Mass (m) of metal =..?

D = m/V

0.486 = m/2.3

Cross multiply

m = 0.486 × 2.3

m = 1.12 g

Therefore, the mass of the metal is 1.12 g.

Explanation:

Answer:

A

Explanation:

Answer:

Explanation:

The formula for the force of gravity is

F=G * m1 * m2 / r^2

G is a constant. It does not change with the use of the formula.  There are 2 masses, so the force depends on the masses.

The right hand side is divided by r^2. that's a distance. So that's the other quantity influencing the Force.

B: incorrect. Both objects have masses. That determines the force between them.

C: incorrect. It's also the distance between them.

D: incorrect. The formula contains nothing to indicate that velocity is important.
