A. Whether the particles of the solute and solvent are charged

B. Pressure acting and solute

C. Length of time spent stirring

D. Temperatures of the solvent and solute

Answer:

The rock displaces 475 mL of water.

475 mL is the volume of the rock.

1 mL = 1 cm^3  

The mass is just density times volume.

m = 475 * 2.5 = 125 g

The definition of colloids is very disputed on whether or not it is homo/heterogenous. I wouldn't go with this answer, but its based on what you learned it was. At a microscopic level its hetero but at a macroscopic its homo.

They do have somewhat large dispersed particles but this better describes suspensions

They don't easily settle out.

And in order to be a mixture, they are made up of at least two substances

D is likely the best answer out of the bunch.

Colloids are made up of at least two substances. Therefore, option d is correct.

A colloid can be described as a mixture in which one substance consisting of dispersed insoluble particles is throughout another substance. The particles should be dispersed in a liquid. The term colloidal suspension can be referred to unambiguously as the overall mixture.

A colloid exhibits a dispersed phase and a continuous phase. The dispersed phase particles have a diameter of about 1 nm to 1 μm. Some colloids are translucent due to the Tyndall effect and other colloids can be opaque or have a slight color.

Hydrocolloids can be described as certain chemicals that are colloidally dispersible in water. Therefore becoming very "soluble" they can change the rheology by raising the viscosity.

A colloid possesses a dispersed phase and a continuous phase. A solute in a solution is individual molecules, whereas colloidal particles can be bigger.

Answer-

Fish are obviously animals because they move, they have sensory organs (eyes, mouth, barbels), and they have body structure (skeletons, skin, etc.). They breathe oxygen. They eat other organisms to survive. Fish are different from other animals because they live in water.

Answer:

The surface fish live near the surface of the water, and the blind cave fish live in dark subterranean caves. The surface fish have eyes and pigmentation on their bodies. The blind cave fish don’t have eyes, and they’re often albinos.

A lithium ion has a charge of   +1.

A calcium ion has a charge of   +2.

An aluminum ion has a charge of   +3.

A fluorine ion has a charge of   -1.

An oxygen ion has a charge of   -2.

Below, the correct charges of the elements are listed;

The ionic or electrical charge of an element is the new state the element acquires because of losing or gaining an electron.

When elements lose their electrons, they tend to attain a positive charge and when they gain an electron, they tend to acquire a negative charge. To easily identify the charge of the ions, the periodic table should be used.

Elements (metals) found on the left side of the periodic table tend to have a positive charge while elements (non-metals) on the right side of the table usually assume a negative charge.

Answer:

The mountains cause rainfall.

Explanation:

The fact that the mountains run parallel to the coast is the key in the difference in climate between the two areas. Since they are parallel to the sea, they block the wind and moisture coming from the sea towards the land, the mountains cause this air to rise and when it hits the cold air at higher altitudes, it results in rain. This leads to the lush and tropical areas whereas without the parallel mountains to the coast, the amount of rain the area receives decreases, resulting in a desert like environment.

Answer:

Option C = 150

Explanation:

First of all we will understand what is law of conservation of mass.

Law of conservation of mass:

This law stated that, mass can neither be created nor destroyed in a chemical equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six number of carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of chemical equation so this reaction followed the law of conservation of mass because mases are same on both side.

In given chemical reaction:

AB    + CD      →      X

50 g +  100 g    =  150 g

Thus option c is correct.

Answer:

a )0.05 moles of O₂

b) 1.1207 dm³

c) 0.3× 10²³ atoms of oxygen

d) 1.6 g

Explanation:

Given data:

Number of molecules of O₂ = 3.01 × 10²² molecules

Number of moles of O₂ = ?

Volume of oxygen at ATP = ?

Number of oxygen atoms = ?

Mass of oxygen = ?

Solution:

The given problem will solve by using Avogadro number.

"It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance".  The number 6.022 × 10²³ is called Avogadro number.

Moles of oxygen:

1 mole = 6.022 × 10²³  molecules

3.01 × 10²² molecules  × 1 mol  / 6.022 × 10²³  molecules

0.05 moles of O₂

Number of atoms of oxygen:

1 mole = 6.022 × 10²³ atoms

0.05 mol × 6.022 × 10²³ atoms /1 mol

0.3× 10²³ atoms of oxygen

Volume of oxygen:

1 mole of oxygen at STP occupy 22.414 dm³

0.05 mol × 22.414 dm³ / 1mol

1.1207 dm³

Mass of oxygen:

Mass = number of moles × molar mass

Mass = 0.05 mol  × 32 g/mol

Mass = 1.6 g

From the question

mass = 4.86 g

volume = final volume of water - initial volume of water

volume = 17.3 - 15.5 = 1.8 mL

Answer:

1 closer

2 24hours

3 tidal bulges

4 in a straight line

Explanation:

Tides have been the effect of the sea with the gravitational pull of the sun and moon.

1. Earth’s tides are affected by the gravitational pull of the Sun and the Moon, but mainly the Moon because the Moon is closer to the earth.

In spite of high pull of the Sun, the distance of moon from earth results in increased effect of moon gravitational pull than Sun.

2. Each day, each coastal region on Earth experiences two high tides and two low tides in every 24 hours time period.

The daily tides has been resulted at the coast with the moon revolution around the earth's rotation.

3. This is because the gravitational attraction of the Moon creates tidal bulges on two opposite sides of the planet.

The effect of the  moon gravitational force results in the bulging or the pulling force to the sea, resulting in the diurnal tides.

4. Two spring tides occur monthly, when the Moon is in its new and full phases. During these phases, the Moon and Sun are oriented at a right angle measuring 90 degrees which gravitation pulls the water on Earth in the same direction, creating a large tidal range.
