A maritime polar air mass is a cold air mass that forms over which two oceans

Answers

Answer 1

Answer:

Answer:

The correct answer is Pacific and Atlantic oceans.

Explanation:

When an air body of a specific site or region reflects the temperature and other climatic condition of water and land it is known as air mass. The air substitutes heat with the water or the land, till the temperature of the air becomes equivalent to that of the surface underneath it. A maritime polar air mass refers to the air mass, which gets produced over the Northern Pacific oceans and the Northern Atlantic oceans. This is accountable for bringing a mass of cold air into the mentioned oceans.

Answer 2

Answer: northern atlantic and northern pacific oceans

How does heat differ from temperature

Answers

Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object.

Molecular bonding cannot occur without..electrons, sunlight, protons, or neutrons?

Answers

Answer:

Molecular bonding cannot occur without electrons.

Explanation:

In order to be 100% correct, the answers should be electrons, protons and neutrons. Since moleculas are formed by atoms and atoms are formed by electrons protons and neutrons.

However, if we consider only the bonding itself, the most important atomic particle is the electron. Molecular or convalent bonding happens when atoms share electrons pairs to reach stability.

What are some uses of metals?

Answers

They are used to make plane bodies.
Some are used for electrical wires eg copper because they are good conductors of electricity.
Used in building materials.

Copper and aluminium wire are used to carry electric current.Copper, aluminium and iron are used to make domestic utensils and factory equipment.Thin foils of aluminium are used for wrapping cigarettes, medicines, confectionery, etc.Aluminium is used for making angles, doors, pipes, etc. which are used in the construction of houses.Metals such as sodium, titanium, zirconium, etc. are used in generation of nuclear energy and in space science projects.Mercury is used in thermometers.Magnesium metal is used as a strong reducing agent to prepare other metals.Gold and silver metals are used to make jewellery.Thin foils of silver and gold are used to decorate sweets.Uranium metal is used to generate nuclear energy.Titanium metal is very hard, resistant to corrosion, light, has high melting point and is good conductor of heat and electricity. Because of its unique and useful properties titanium is sometimes called ‘the wonder metal’.

When a substance dissolves, it undergoes a chemical change.
a. True
b. False

Answers

False.

Solubility is not a chemical property but rather it is a physical property. A physical property is one that can be observed or measured and does not change the composition or identity of a substance in the process.

When a substances dissolves, this is a change of its physical state and it is mostly reversible. For example, salt can dissolve in water to form a solution called brine. This does not alter the chemical nature of salt. When the water evaporates, salt is left behind in its original state or form. In other words, that was a physical change and it was completely reversible.

Given the formula representing a compound: what is a chemical name of this compound? 2-pentene 2-pentyne 3-pentene 3-pentyne

Answers

The question is incomplete. Complete question is attached below.
..........................................................................................................................

Correct Answer: Option 1) 2-pentene

Reason:
Following are the IUPAC rules for naming the compound
1) Select the longest carbon chain. In present case longest carbon chain has 5 carbon atom. Hence, it is a pentane derivative.
2) In case of alkene, replace 'e' of alkane by 'ene'
3) Give lowest number to function group. In present case, it is double bond.

Applying above rules, the IUPAC name of compound is 2-pentene
