The bonds that link many water molecules together to form a water drop are _____ bonds.ionic
nuclear
hydrogen
covalent

Answers

Answer 1

Answer:

The bonds found between water molecules are called:

Hydrogen bonds

which contribute to water having a high number of Van Der Waals forces.

Explanation:

A hydrogen bond is an electromagnetic attraction within polar molecules in which hydrogen is joined to a larger atom, such as oxygen or nitrogen. This is not a dividing of electrons, as in a covalent bond. Preferably, this is an attraction among the positive and negative poles of charged atoms.

Answer 2

The Great Migration during World War I refersto the movement of
(1) factory workers from the Northeast to the
Sun Belt
(2) communists deported to Russia as
undesirable aliens
(3) African Americans to northern cities to find
work
(4) refugees fleeing from eastern Europe to the
United States

Answers

The Great Migration during World War I refers to the movement of African Americans to northern cities to find work. Therefore, option (3) is correct.

What is Great migration?

The Great Migration was the movement of millions of African Americans moved from the rural Southern United States to the urban Northeast, Midwest, and West. The great migration was caused by the poor economic conditions for African American people.

The historic change brought by the migration was fueled because the migrants moved to the largest cities in the United States such as New York City, Chicago, Los Angeles, Philadelphia, Cleveland, and Washington, D.C. at a time when these cities had a central social, political, cultural and economic influence over the United States.

African Americans established effective communities of their own. Therefore the Great migration movement was actually sending African Americans to northerncities to find work.

If a runner completes a 10 kilometer race in 32.50 minutes, what is the 10.0 km pace in miles per hour? (1.609 km = 1 mile approximately)

Answers

If a runner completes a 10 km race in 32.5 minutes, his pace or speed can be calculated by the equation:

velocity = distance/time = 10km/32.5 mins = 0.3125 km/min

Convert this value to miles per hour using the conversion factors for minutes to hours and kilometers to miles as requested by the problem. This gives an answer of 11.47 miles per hour.

0.3125 km/min x 60 mins./ 1 hour x 1 mile / 1.609 km = 11.47 miles/hour

Explain how the system of the flask and the balloon illustrates the conservation of mass.

Answers

The mass of the reaction system is conserved because, the mass lost from the reaction by the evolution of gas is collected inside a balloon to inflate it. Thus , the balloon and the flask creates a closed system where no mass is lost outside.

What is conservation of mass?

According to the law of conservation of mass, the mass can neither be created nor be destroyed. Thus the total mass of the system is conserved. However similar to the energy, mass can be transformed into energy.

As per this law, the total mass in a chemical reaction is conserved. Where, the total mass in the reactant side is equal to the total mass in the product side.

When the reaction flask is closed with a balloon, the gas if any evolved from the reaction will be collected to the balloon and it inflates. Thus the mass lost from the reaction system does not goes to the surroundings due to the closed system.

Both containers prevent the escape of matter of the reaction into an uncontrolled space, therefore it is a closed system (not isolated, since energy can still go in and out).

The atmosphere's variable gases that most influence the greenhouse effect are _____. nitrogen and oxygen argon and carbon dioxide carbon dioxide and water vapor water vapor and ozone

Answers

The correct answer is carbon dioxide and water vapor

These negative gasses get modified and then remain in the atmosphere without the possibility of leaving, which is why the greenhouse effect occurs.

Answer;

Carbon dioxide and water

The atmosphere's variable gases that most influence the greenhouse effect are carbon dioxide and water.

Explanation;

Green house effect is a phenomenon where the radiation from the atmosphere of the earth warms the surface of the earth to a temperature above what it would be. It occurs when the atmosphere traps heat radiating from the earth towards the space.
Certain gases in the atmosphere block the heat from escaping, these gases are called the green house gases. These gases contribute to the green house effect, they include, water vapor which is the most abundant green house gas, carbon dioxide a very important component of the atmosphere, methane, nitrous oxide, CFCs, etc.

How does vegetation slow and prevent sediment loss?

Answers

Vegetation cover is the most effective and practical way to prevent loss of sediment. The roots of vegetation such as grass bind soil particles together to resist erosion especially from runoff water. Vegetation helps absorb the impact of raindrops to prevent detachment of soil particles. Vegetation can flatten act like shingles on a roof, which allows the runoff to flow above the soil.Stiff standing vegetation act as a wind break, reducing wind velocity, such that it is not powerful enough to dislodge sediments from the ground surface.

Final answer:

Vegetation slows and prevents sediment loss in rivers and streams by binding the soil together and slowing down the flow of water. Shade from plants also helps reduce phytoplankton growth.

Explanation:

Vegetation plays a crucial role in slowing and preventing sediment loss in rivers and streams. The roots of plants help bind the soil together, reducing erosion caused by the force of water. As water flows through vegetation, it is slowed down, allowing sediment to settle out. Additionally, plants provide shade, which helps keep the water temperature lower, creating an environment less suitable for phytoplankton growth.
