Explanation:

Answer: 11.25 moles of [tex]O_2[/tex] will be required to completely react with 2.25 moles of [tex]C_3H_8[/tex].

Explanation:

The balanced chemical equation is:

[tex]C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g)[/tex]  

According to stoichiometry :

1 mole of [tex]C_3H_8[/tex] require = 5 moles of [tex]O_2[/tex]

Thus 2.25 moles of [tex]C_3H_8[/tex] will require=[tex]\frac{5}{1}\times 2.25=11.25moles[/tex]  of [tex]O_2[/tex]  

Thus 11.25 moles of [tex]O_2[/tex] will be required to completely react with 2.25 moles of [tex]C_3H_8[/tex].

Answer:

Explanation:

what is the independent variable

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:

DNA aka deoxyribonucleic acid is a molecule in cells that holds genetic information. Their main job is to tell the cell what type of protein to make. The other instructions they hold for the organism is instructions on how to develop, survive and reproduce.

Explanation:

DNA is the genetic material made of two polynucleotide chains that coil around one another to create a double helix is called deoxyribonucleic acid (DNA).

All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction. Nucleic acids include ribonucleic acid and DNA.

DNA is the genetic material found inside bodily cells that contribute to an individual's unique genetic makeup. Similar to the game's code or a home's blueprints, it contains the directions for creating the body.

Explanation:

Answer:

[tex]\boxed {\boxed {\sf 447,560 \ Joules}}[/tex]

Explanation:

We are asked to find the energy required to melt 1340 grams of ice. We are given this formula:

[tex]Q=mL[/tex]

In this formula, Q is the heat, m is the mass, and L is the latent heat.

For this problem, the mass is 1340 grams of ice. Since we want to melt the ice, we need the latent heat of fusion (melting) which is 334 Joules per gram.

[tex]m= 1340 \ g \\L= 334 \ J/g[/tex]

Substitute the values into the formula.

[tex]Q= (1340 \ g )( 334 \ J/g)[/tex]

Multiply. The grams will cancel each other out.

[tex]Q=1340 *334 \ J \\Q=447560 \ J[/tex]

447,560 Joules of energy are needed to melt 1340 grams of ice.

Answer:

A. The atoms have more energy together than separated.

Explanation:

There are several reasons why a chemical bond could take place. Adding things like heat or pressure stimulate the atoms to force a reaction to take place. But when it comes down to it, the intramolecular forces of the electrons  pull each other to form chemical bonds (represented by Valence electrons). The stronger these are, the more likely they are going to bond.

Atoms with lower forces typically don't typically bond with other atoms of lower forces.

Answer:

  14. left; 10 > 3

Explanation:

All you're being asked to do is count the squares in the pictures.

11. The number of squares for the left wave from bottom to top is 2, so the amplitude is 1/2 that, 2/2 = 1. For the right wave it is 9 squares from bottom to top, so the amplitude is 9/2 = 4.5.

  left amplitude: 1, right amplitude: 4.5

__

12. The right wave has greater amplitude. Evidence: 4.5 > 1. It also takes up more vertical space in the picture.

__

13. It is difficult to determine the wavelength of the left wave, because two full peaks are not shown. If we try to match corresponding points, they appear to be about 10 squares apart.

The right wave has 2 peaks in 6 squares, so about 3 squares between peaks.

  left: wavelength 10, right: wavelength 3

__

14. The left wave has greater wavelength. Evidence: 10 > 3.

Answer:

10 Kelvin

Explanation:

this is so simple...

if you want to raise the temp from 270K to 280K just add 10K

According to specific heat capacity, 4200 joules of heat must be added to raise a sample of 100.g of water at 270 K to 280 K.

Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.

It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.

It is given by the formula ,

Q=mcΔT , on substitution of values on given formula, Q= 100×4.2×10=4200 Joules

Thus, 4200 joules of heat must be added to raise a sample of 100.g of water at 270 K to 280 K.

Answer:

El Niño

Explanation:

The natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America Is the El Niño.

El Niño is a climate pattern that happens when there is an unusual warming of the surface temperatures of the Pacific Ocean. This occurs at an interval of two to seven years

During El Niño, the  surface waters of the Pacific Ocean become warmer than average and this is as a result of the weakness of trade winds which blows over the entire Pacific Ocean. This makes the atmospheric pressure above the ocean to decrease.

El Niño brings rainfall nd flooding to South America and droughts in the western United States

Answer:

See explanation

Explanation:

There are two main factors that affect the magnitude of thermal energy of a system.

The thermal energy of a system depends on

i) Temperature of the body

ii) Mass of the body

Thus, the greater the mass of a substance at a particular temperature, the greater its thermal energy.  Also, at a higher temperature, an object  has greater thermal energy.

Option 3, The attraction between the can and the magnet is a pull.

Explanation:

The complete question is

Mr. Wang works in a recycling center. Recyclable materials arrive at the

center mixed together. Workers use magnets to separate steel cans from

other items. Which two statements are true about the force between a steel can and a magnet?

1 Gravity pushes the can toward the magnet.

2 The force between the can and the magnet is a noncontact force.

3 The attraction between the can and the magnet is a pull.

4 The attraction between the can and the magnet is a push

Solution

The force exerted by magnet on steel is the pull force. In magnets unlike poles attract each other (pull force) while the like poles repel (push force). Now, the steel or any ferrous object in the garbage when experience magnetic field develop magnetic field of their own in such a way that their north always faces the south of the external magnet or vice versa.

Hence, the force between a steel can and a magnet is pull force
