Answer:

When air in contact with the ocean is at a different temperature than the sea surface, heat transfer by conduction takes place. The ocean also absorbs and stores energy from the sun, and when precipitation falls, it releases heat energy into the atmosphere.

Hope it helps:)

We can use the formula. 

c1v1 =c2v2

Where c1 is the concentration and v1 is volume of the concentrated solution. 

c2 is the concentration

and v2 is the volume of the diluted solution to be prepared

9.00 M x V1 = 2.75 M x 350 mL

V1 = 106.9 mL

Volume of 106.9 mL from the concentrated solution should be taken and diluted to 350 mL.

Answer:

a colloid

Explanation:

Paint is classified a colloid

A colloid is a homogenous of two phases which are the dispersed phase and the dispersion medium.

The dispersed phase is analogous to the solute of the true solution while the dispersion medium is analogous to the solvent.

The particles of colloids are larger than those found in a solution.
Their particles do not settle on standing
Their particles pass through ordinary filter paper
Their particles do not pass through permeable membranes

Select all of the following statements that are basic assumptions of the Bohr model of the atom. Atoms have a central nucleus wi

Alekssandra [29.7K]

Answer:

The assumptions of the Bohr model of the atom are:

- Atoms have a central nucleus with electrons in orbit about this nucleus.

- They must gain energy to jump to a higher level, and they release energy when jumping to a lower level.

- Electrons orbit the nucleus, but the orbits can have only certain sizes and energy values.

Explanation:

The Bohr model of the atom establishes that atoms have a central nucleus with positive charge and electrons (with a negative charge) in orbit about this nucleus. In the Bohr model, electrons move in specific orbits with a certain amount of energy and can't jump from one orbit to another around the nucleus. To jump to a higher level, they must gain energy or release energy when jumping to a lower level.

The Thomson model of the atom postulated that atoms are solid spheres of matter and are made of positive material with electrons fixed in place in this positive material.

sveticcg [70]

Answer: You meant in constant temperature?

Because temperature is not mentioned at the beginning.

I suppose temperature remains constant, otherwise

there is no enough data for solving the problem

Explanation: According Boyle´s law in constant temperature

pV = constant. So p1V1 = p2V2 and pressure p2 = p1V1 /V2

= 88 atm · 18 l / 12 l = 132 atm.

Calculate each of the following quantities: (a) Mass (kg) of 4.6X10²¹ molecules of NO₂

Oksanka [162]

The mass (kg) of 4.6 x 10²¹ molecules of NO₂ is 351 grams.

<h3>What are molecules?</h3>

Molecules are two or more joined atoms by a chemical bond. It formed a substance that can be of similar or different molecules.

Mass is calculated by multiplying the moles and molar mass of the substance.

Mass = moles x molar mass

The number of molecules of NO₂ is 4.6 x 10²¹

To calculate the number of moles from given molecules, divide the

4.6 x 10²¹ / 6.023 x 10²³ = 7.637 x 10⁴³ moles

Our moles is calculated

The molar mass is 46 g/mol

Putting the value in the equation

mole = mass/molar mass

mass = moles x molar mass

7.637 x 10⁴ x 46 = 351 grams

Thus, the mass (kg) of 4.6 x 10²¹ molecules of NO₂ is 351 grams.
