Answer:

The volume will decrease.

Explanation:

According to Charles' Law, the volume of a gas is directly proportional to its temperature.

V = kT

Thus, if T decreases, V decreases.

Explanation:

So,when balloon filled with helium gas was placed in lower temperature we will observe that the volume of the helium gas inside the helium will decrease due to which size of the balloon will also get decreased.

This is because volume is directly proportional to the temperature of the gas at constant pressure and number of moles. And this law is known as Charles law of

V\propto T    (At constant pressure and number of moles)

Answer:

Due to presence of a triple bond between the two N−atoms, the bond dissociation enthalpy (941.4 kJ mol  

−1

) is very high. Hence, N

Which best describes why a liquid needs a container when a solid does not?Solids fill their containers, and liquids have definit
Rina8888 [55]

The correct answer choice which best describes why a liquid needs a container when a solid does not is simply because:

Solids have definite shapes, and liquids fill their containers.

Matter is classified as element, compounds and mixtures

<h3>What is an element?</h3>

An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.

An atom is the smallest unit or part of an element which can take part in a chemical reaction.

On a general note, elements are classified as thus:

  • Metals, non-metal, and metalloid.

  • The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.

  • However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,

So therefore, the correct answer choice which best describes why a liquid needs a container when a solid does not is simply because:

Solids have definite shapes, and liquids fill their containers.

Balance the equation: "Sodium oxide reacts with water to form sodium hydroxide and hydrogen." I can't find the correct coefficie
dedylja [7]

Answer:

So, sodium oxide + water = sodium hydroxide + hydrogen is written Na2O+H2O-->NaOH+H.

To balance the equation it should read NaO+H2O-->2NaOH

Explanation:

Na2O+H2O-->2NaOH+0H2.......the 0H2 is dropped because there is no value

8. An unknown mixture that is uniform, does show the Tyndall Effect, and does
Mariulka [41]

Answer:

B. Colloid

Explanation:

Colloid is a mixture that is made up of very small homogeneous particles, thus can not be separated into fractions. Its particles do not settle as other solution, but are evenly dispersed in the medium. Some examples are: liquid milk, jelly, rubber etc

Since colloid is a solution, thus it is made up of two parts; its particles and dispersing medium.
