Explanation:

The mass of boy weighing 270 N has been 27.55 kg.

The mass of the object has been determining the quantity of the matter, while weight of the object has been the mass with the gravitational pull.

The weight of the object has been given as:

Weight = mass × gravitational constant

Weight of boy = 270 N

Gravitational constant = 9.8

The mass of boy is:

270 = mass × 9.8

[tex]\rm Mass\;=\;\dfrac{270}{9.8}[/tex]

Mass = 27.55 kg.

The mass of boy weighing 270 N has been 27.55 kg.

Answer:

Option D.

Explanation:

Let's balance the hole reaction by the ion electron method.

Al (s) + Cr(NO₃)₂ (aq) – Cr (s) + Al(NO₃)₃ (aq)

We know that oxidation state at ground state is 0.

We determine the half reactions:

Al  ⇆   Al³⁺  +  3e⁻

Aluminum increase the oxidation state. This is the oxidation.

Cr²⁺ + 2e⁻  ⇄   Cr

Chromium decrease the oxidation state. It changed from +2 to 0.

This is the reduction. In order to balance the half reactions, we need to multiply by 2 and by 3. In that way, we can cancel the electrons:

(Al  ⇆   Al³⁺  +  3e⁻) . 2

(Cr²⁺ + 2e⁻  ⇄   Cr) . 3

We sum the half reactions:

2 Al + 3 Cr²⁺  +  6e⁻  ⇄  2Al³⁺  +  6e⁻ + 3Cr

We cancel the electrons, so now the balanced reaction is:

2Al + 3Cr(NO₃)₂  →  3Cr  + 2Al(NO₃)₃

Final answer: 6 electrons are transferred in the redox reaction.

Cold water causes a strong reaction between all alkali metals. Each reaction results in the release of hydrogen gas and the production of metal hydroxide.

The six chemical elements that make up Group 1 ( Ia ) of the periodic table—lithium ( Li ), sodium ( Na ), potassium ( K ), rubidium ( Rb ), cesium ( Cs ), and francium—are together referred to as alkali metals ( Fr ). The name "alkali metals" refers to how they react with water to produce alkalies.

The elements in Group 1 are all extremely reactive. To protect them against air and water, they must be kept under oil when being stored. Group 1 elements produce alkaline metal hydroxides when they interact with water (with a pH above 7). They are known as "alkali metals" for this reason.

Thus, the elements in group 1 react with water to form a hydroxide and hydrogen gas is produced.

Answer:

1.) Metals are the only substances that use metallic bonds among their atoms. While many elements are commonly known as metals, including iron, aluminum, gold, silver and nickel, metals include a variety of other elements as well. 2.) In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.

Explanation:

3.) Metallic bonding is utilized for its conductive properties to help transfer electricity throughout a house via copper wiring.

Answer:

[tex]\boxed {\boxed {\sf A. \ 19,320 \ kg/m^3}}[/tex]

Explanation:

We want to find the density. The formula is mass over volume.

[tex]\rho = \frac{m}{v}[/tex]

The mass is 500 kilograms. The volume is 0.026 cubic meters.

[tex]m= 500 \ kg \\v=0.026 \ m^3[/tex]

Substitute the values into the formula.

[tex]\rho= \frac{ 500 \ kg}{ 0.026 \ m^3}[/tex]

Divide.

[tex]\rho = 19230.7692 \ kg/m^3[/tex]

This is just about equal to 19,320 kg/m³, so choice A is correct.

Answer:

A) 19230 kg/ m3

Explanation:

divided it's mass by its volume ti get it's density

500/0.026 = 19230
