An element that is malleable is _____. difficult to pour easily shaped very hard very dense

1 answer:

6 0

The answer is easily shaped. Malleable means it can be shaped with ease without breaking them.
This is a common property in metals. For example, aluminum, they can be shaped into thin aluminum foil sheets because they're malleable.
In the other hand, for many non metals and semi metals, they're brittle, the opposite of malleable. They tend to break easily.

Which of the definitions below is best for the word molecule? Atoms of different elements chemically joined together More than o

gayaneshka [121]

Answer: More than one atom of the same type chemically joined together

Explanation:

An atom is the smallest unit of any matter which may or may not have independent existence. Example: Argon (Ar) is an element which exist as Ar atom only.

Molecule is the smallest unit of any matter which always have independent existence. For example: Hydrogen (H) is an element which can exist in nature as $H_2$ molecule only.

Atoms of different elements chemically joined together is called as a compound. Example: $H_2O$ is a compound formed by chemical combination of hydrogen (H) and oxygen (O) atom.

What is the difference between a strong and weak acid?

Mademuasel [1]

Answer:

The strong acids are fully ionized in aqueous solution, and they contains higher concentration of hydrogen ions. Strong acids are lower pH in nature. Some examples of strong acids are:

1) Hydrochloric acid.

2) Nitric acid.

3) Sulfuric acid.

The weak acids are not fully ionized, means they are partially ionized in aqueous solution, and they contains lower concentration of hydrogen ions. Weak acids are higher pH in nature than strong acid. Some examples of weak acids are:

1) Ethanoic acid.

2) Acetic acid.

3) Nitrous acid.

Why is the vapor pressure of a warm pale higher than the vapor pressure of a cold lake

levacccp [35]

The vapor pressure of a warm pale higher than the vapor pressure of a cold lake because Warm water evaporates more quickly.

Hence, Option B is correct answer.

<h3>What is Evaporation ? </h3>

The process in which a liquid or solid is converted into vapour is called Evaporation. When water gains the heat energy then it changes in to gas. When the temperature increases it speeds up the rate of evaporation.

The temperature of warm water increases, the kinetic energy of the warm water molecule also increases.

Thus from the above conclusion we can say that The vapour pressure of a warm lake is higher than the vapor pressure of a cold lake because Warm water evaporates more quickly.

Hence, Option B is correct answer.
