Stationary front is a combination

HOPE I helped :]

Answer:

stationary front

Explanation:

on a weather map, a stationary front is shown as alternating red semicircles and blue triangles like in the image at the left. notice how the blue triangles point in one direction, and the red semicircles point in the opposite direction.

Answer: 322.56 Kelvin

Explanation:

Use the Ideal Gas Law

[tex]PV=nRT[/tex]

R is the gas constant

T is the temperature in Kelvins

P is the pressure in atmospheres

V is the volume in liters

n is the number of moles of gas

First, the mm of mercury need to be converted to atmospheres using the conversion factor 1atm = 760 torr.

[tex]751.2mmHg (torr) =0.988atm[/tex]

Now plug everything in

[tex](0.988)(26)=(0.97)(0.0821)T\\T=322.56K[/tex]

Answer:Land Population

Answer:

The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.

Answer:

A chemical reaction in which an uncombined element replaces an element that is part of a compound is called a simple substitution reaction or simple displacement reaction.

Explanation:

A simple substitution reaction or simple displacement reaction, called single-displacement reaction, is a reaction in which an element of a compound is substituted by another element involved in the reaction. The starting materials are always pure elements and an aqueous compound. And a new pure aqueous compound and a different pure element are generated as products. The general form of a simple substitution reaction is:

AB + C → A +BC

where C and A are pure elements; C replaces A within compound AB to form a new co, placed CB and elementary A.

So, in a Single replacement reaction an uncombined element replaces an element.

A chemical reaction in which an uncombined element replaces an element that is part of a compound is called a simple substitution reaction or simple displacement reaction.

Answer:

Explanation:

To convert the mass to moles, divide the mass by the atomic weight of the element or compound.

To convert back to mass from the moles, multiply the moles by the atomic weight of the element or compound

Answer:

Explanation:

When a comet enters the solar system it curves towards the Sun due to the Sun's gravitational pull. Every celestial object in the universe has a gravitational pull whose force is dependent on the object's mass. The larger the object is the more gravitational pull it will have. The Sun is the largest object in our Solar system and therefore has the most gravitational pull. This is why the comet curves toward the Sun, but the opposite does not happen because the comet's gravitational pull is not strong enough to pull the Sun.

Answer:

The hydroxide ion concentration in an aqueous solution, [OH-], in mol L-1, can be calculated if the pOH of the solution is known.

pOH is defined as the negative logarithm (to base 10) of the hydroxide ion concentration in mol L-1 pOH = -log10[OH-]

Explanation:

Numbering the steps in the correct order to show how ice changes into gas, we have that

1.Ice molecules vibrate in a fixed place.

2. Ice is heated and the molecules speed up

3. The molecules gain enough kinetic energy to leave their solid form.

4.The water becomes liquid and gets hotter.

5. The molecules leave their liquid form and enter the air as a gas.

Ice is the solid form of water  which cannot freely move around in this form  so  it vibrates  about its fixed position.When heated,its molecules acquire energy and its vibration  speeds up  causing it to overcome its  binding forces (that makes it vibrate about a fixed position) and becomes mobile as it leaves its solid form to acquire a liquid state.    With continuous heating, the liquid gets hotter making the molecules vibrate more rapidly, spread out and move freely at high speeds to form Water vapour - The gaseous state of water.

Answer:

2.00

Explanation:

From Graham's law; the rate of effusion is inversely proportional to the square root of the relative molecular mass.

Let the rate of effusion of Helium be R1

Let the rate of effusion of Methane be R2

Let the molecular mass of Helium be M1

Let the molecular mass of Methane be M2

Hence;

R1/R2 = √M2/M1

R1/R2 = √16.0294/4.0026

R1/R2 = 2.00

The specific heat of a substance represent the ability of a substance to hold heat. Therefore, the correct option is option B.

The amount of heat needed to raise a substance's temperature by one degree Celsius in one gram, also known as specific heat. Typically, calories as well as joules for every gram per degree Celsius are used as the measures of specific heat.

The notion of specific heat was developed by the Scottish scientist William Black in the 18th century as a result of his discovery that identical quantities of different substances required varying quantities of heat to raise them within a comparable temperature range. The specific heat of a substance represent the ability of a substance to hold heat.

Therefore, the correct option is option B.

Answer: Ion-Dipole

Explanation: I took the CK-12 practice and got it right

When KCL dissolved in ethanol, the intermolecular attraction between K+ ions and ethanol molecules is ion - dipole interaction.

The term ion-dipole interaction is defined as the intermolecular force of attraction between cation or anion and a molecule. It is present in the solution where ionic compounds dissolve in polar solvents.

Due to the polar O-H group's presence in the molecule, ethanol is a polar substance. Thus, the molecule has a dipole moment. The dipole's positive end rests on hydrogen, and its negative end rests on oxygen.

K+ ions can interact with the ethanol's negative end of the dipole through ion-dipole interaction when KCl is dissolved in the alcohol.

Thus, When KCL dissolved in ethanol, the intermolecular attraction between K+ ions and ethanol molecules is ion - dipole interaction.
