Answer:  Mountains block the winds that bring rain clouds.

Explanation: By acting as obstacles to the flow of air masses, mountains contribute significantly to the dryness of deserts. Orographic lifting is a process that occurs when moist air is forced to ascend as it approaches a mountain range. The moisture in the air condenses and forms clouds as the air cools as it climbs. As a result, on the windward side of the mountains, the air loses a lot of its moisture as precipitation. The air has already lost a significant amount of moisture by the time it reaches the leeward side of the mountains, creating a rain shadow effect. On the leeward side of the mountains, this impact results in a dryer area that is often a desert. Consequently, the existence of mountains influences

The statement which is not a characteristic of an atom is - contains at least one bond. Option C is correct.

An atom is made up of electrons, protons and neutrons. Electrons, protons and neutrons are negatively charged, positively charged and neutral in nature. In the structure of an atom, the neutrons and protons are present in the nucleus whereas electrons are present in the orbits surrounding the nucleus. They exist independently in their elemental form. The element Oxygen, which is represented by O is taken as an example, it consists of only one element and doesnot contain a bond.

Thus option C is correct.

Answer:

When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

2.After a cold front moves through your area, you may notice that the temperature is cooler, the rain has stopped, and the cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies.

3.Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.

Answer:

4) Mixtures contain different substances with different properties and chemists can separate one item from the mixture by forcing it to undergo a chemical change.

Explanation:

Mixtures contain different substances with different physical properties, such as boiling point, melting point, solubility, density, and so on. These properties can be used to separate the individual substances in the mixture through various techniques. For example, distillation is a separation technique that relies on differences in boiling points of the substances in a mixture. When a mixture is heated, the substance with the lower boiling point will vaporize first, and it can be collected and cooled to form a pure substance. Similarly, other techniques such as chromatography, filtration, and crystallization also rely on differences in physical properties to separate mixtures.

On the other hand, chemical changes involve the rearrangement of atoms within a substance, resulting in the formation of a new substance with different properties than the original. While chemical changes can be used to synthesize new substances, they are not typically used to separate mixtures.

Explanation:

Answer: C2H4 + 3O2 > 2CO2 + 2H2O

Explanation:

The law of conservation of mass has been given as the mass cannot be created nor be destroyed in a chemical reaction. The law of conservation of mass has equal weight of the reactants and the products.

The mass of following reactions can be given as:

28 g   + 3(32)g =  2(44)g  +  2(18)g    Mass

124 g              =   124 g

Thus, the reaction follows the law of conservation of mass.

12g + 4(2)g   =   16g

20g = 16g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

3(18)   = 3(2) + 3(32)

54g = 102g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

2(23) + 36.5 = 58.5 g

81.5g = 58.5g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

The reaction that has been following the law of conservation of mass has been reaction 1. Thus, option 3 is correct.

Which of the following equations follows the Law of Conservation of Mass?

2Na + Cl > NaCl

C + 4H2 > CH4

C2H4 + 3O2 > 2CO2 + 2H2O

3H2O > 3H2 + 3O2

C2H4 + 3O2 > 2CO2 + 2H2O

The mass of the following reactions can be given:

28 g   + 3(32)g =  2(44)g  +  2(18)g    Mass

124 g              =   124 g

Thus, the reaction follows the law of conservation of mass.

The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.
