Answer:

d = 0.057 g/mL

Explanation:

Given that,

The dimensions of a rectangular metal is 25 dm long, 525 mm wide, and 1.5 m high.

The weight of the metal is 250 lb

We need to find the density of the metal in g/mL.

1 lb = 453.592 g

250 lb = 113398 g

Volume of the block,

V = 25 dm× 525 mm×1.5 m

Since, 1 dm = 0.1 m, 1mm = 0.001 m

V = 2.5 m× 0.525 m× 1.5 m

V = 1.9668 m³

Also, 1 m³ = 1968000 mL

So,

density = mass/volume

density = 113398 g/1968000 mL

= 0.057 g/mL

So, the density of a rectangular metal is 0.057 g/mL.

Explanation:

Matter is defined as anything that has mass and takes up space (it has volume).

Answer:

+2

Explanation:

All the alkaline earth metals have 2 valence electrons in their valence shell. Therefore, they lose 2 electrons to form cations with a +2 charge. For example, Mg²⁺.

Answer: a responsibilty

Explanation:

An obligation to do something or control over or care for someone. ​The word suitable for it is "responsibility".

An obligation is a duty or responsibility to do anything that is required by law, custom, or moral standards.

Responsibility is an obligation to do something or control over or care for someone. It is a duty or task that one is required to undertake.

Responsibility can be of different forms, such as personal, social, or professional.

Personal responsibility refers to the responsibility that an individual has for their own actions and decisions.

Social responsibility refers to the responsibility that an individual or organization has to act in the best interest of society.

Professional responsibility refers to the responsibility that individuals have to perform their job duties to the best of their ability.

Therefore, the term most suits for the given statement is "responsibility".

All matter has thermal energy because atoms are constantly in motion, due to motion all matter possess a kinetic energy. The total kinetic energy is known as thermal energy.

The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes

Thermal energy and temperature are closely related. Both reflect the kinetic energy of moving particles of matter. However, temperature is the average kinetic energy of particles of matter, whereas thermal energy is the total kinetic energy of particles of matter.

It increases or decreases only when the velocity changes, heavier objects, It can transform into other types of energy. It will occur regardless of the moving object's direction of travel.

Thus, all matters has thermal energy because atoms are constantly in motion.

Answer:

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... If that velocity is zero, then the object remains at rest.

Explanation:

Answer:

Before Galileo and Newton, many people thought that objects lost speed because they had a built-in natural tendency to do so. But those people weren't taking into account the multiple forces here on Earth - for example, friction, gravity, and air resistance - that cause objects to change their speed. If we could see the motion of an object in deep interstellar space, we would be able to observe the natural tendencies of an object that is free from any external influence. In deep interstellar space we would observe that if an object had a speed, it would continue to move with that speed until there was some force causing a change in its motion. Likewise, if an object were at rest in interstellar space, it would remain at rest until there was a force causing a change in its motion.

Answer:

, containing 2.65 X 1020 molecules.

Explanation:

The mass of a sample of fruit sugar (fructose) C₆H₁₂O₆, containing 2.65 ×10²⁰ is equal to 2.88 g.

Avogadro’s number can be defined as the number of units in one mole of any chemical substance. Generally, these entities can be electrons, molecules, atoms, ions, or protons, depending upon the kind of chemical reaction or reactants and products.

The value of Avogadro’s constant is found approximately 6.022 × 10²³ mol⁻¹.

Given, the number of molecules of fructose = 2.65 ×10²⁰

The molar mass of the fructose = 180.16 g/mol

So 6.022 × 10²³ molecules of fructose have mass = 180.16 g

Then 2.65 × 10²⁰ fructose molecules will have mass = 2875.04 × 10⁻³ g

The mass of the  2.65 × 10²⁰ fructose molecules =  2.88 g

Therefore, the mass of  2.65 × 10²⁰ fructose molecules is equal to 2.88 g.
