Jones Soda contains 33g added sugar (C6H12O6) in a 355 ml bottle, while Sierra Mist contains 62g added sugar in a 591 ml bottle. Which beverage is more concentrated (has a higher molarity) for sugar?
Sierra Mist
Jones Soda

Answers

C6H12O6 molar mass: 180.15768 g

solute: sugar

molarity = moles of solute / liters of solution

Jones Soda:

33 g / 180.15768 g = 0.18 moles C6H12O6

M = 0.18 g / 0.355 L

M = 0.52

Sierra Mist:

62 g / 180.15768 g = 0.34 moles C6H12O6

M = 0.34 g / 0.591 L

M = 0.58

Sienna Mist has a higher molarity and is more concentrated.

39 which statement about the process of dissolving is TRUE
A. Dissolving releases energy in the form of heat.
B. Solvent can be dissolved faster when stirring is applied.
C. Applying heat often speeds up the process of dissolving particles.
D. Once a solute, such as salt crystal is dissolved in a solvent such as
water, it can never return to its original crystal state.

Answers

C !!!!!!!!!!!!!!!!!!!!!!

According to the concept of solubility,applying heat often speeds up the process of dissolving particles.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Arrange the following elements in order from lowest to highest first ionization energy : AI , Ar, Cs, Na .

Answers

Answer:francium

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Explanation:

The least measure of the energy needed to remove the loosely bound electron of an atom or a molecule is called ionization energy.

The correct order from lowest to highest first ionization energy is:

Cs

Na

Al

Ar

This can be explained as:

(Cs) Caesium will have the lowest energy because in the periodic table it comes in the same group as (Na) sodium.

In the group, from top to bottom the ionization energy decreases.

(Al) aluminium and (Ar) argon lies in the same period.

In a period from left to right the ionization energy increases.

Therefore, Cesium will have the least ionization energy as compared to sodium, aluminium and argon.

How might water high specific heat capacity affect energy distribution and temperature on earth

Answers

Answer:

Water can hold a lot of heat inside it and as the climate starts getting cold, the water releases the heat which heats up the climate

Due to the fact that water has a high heat capacity, its temperature has a very limited range, which causes the coastal areas close to having a similar small daily and seasonal temperature range.

What is specific heat capacity?

"When the temperature of a material rises 1 K (or 1 °C), the amount of heat (J) absorbed per unit mass (kg)".

When the weather begins to grow chilly, water releases the heat it has stored inside, warming the environment.

High specific heat of the water makes it temperature resistant, and it helps the earth to maintain its temperature and helps organisms to maintain their functions at a constant temperature of the earth.

Thus, the normal temperature is necessary for maintaining the temperature of the earth and the water bodies maintain the temperature of the earth.

When a piece of paper with words on it is placed behind a clear jar of water the letters seem to change size. Some appear larger, and others appear smaller. Why does this happen? What is light doing to make the letters appear differently?

Answers

Answer:

because of the process of refraction of light.

Explanation:

Note, the term refraction refers to the process which results in the bending of light as it passes through a medium. This bending of light can make objects become magnified (or larger), or even smaller.

In this scenario, as the light passes slowly through water it affects how we perceive the objects (the words on the paper) behind the jar (more likely a glass jar). In other words, the light combined with the water refracts (changes direction of) the lights our eyes can see, making the letters seem to change size.

E. The force between polar molecules when the opposite partial charges of a molecule exert a

Answers

Answer:

A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules. Other examples include ordinary dipole-dipole interactions and dispersion forces. Hydrogen bonds are are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.

Explanation:

if freshwater is added to a region, what happens to seawater density and salinity?

Answers

Answer:

The density and salinity goes down.

Explanation:

Salt water is denser than pure water.  As fresh water is added to salt water the concentration of salt goes down.  Since salinity is the amount of salt in the water that would go down with the concentration.  This would also mean that the density goes down since there is less salt per unit of volume which makes it so that there is less mass per unit of volume.  The formula for density is d=m/v so as the mass goes down per unit of volume so does the density.

1. Which pair of atoms will share electrons when a bond is formed between them? Explain why.

A. K and Cl B. Li and I C. Br and Cl D. Ba and I

Answers

Answer:

C. Br and Cl

Explanation:

When Br and Cl combines they share electrons between them to form a type of bond called covalent bond.

The sharing of electrons between two atomic species is covalent bond. It usually occurs between two atoms with a low electronegativity difference among them. Br and Cl have low electronegativity difference. Also, the bond forms between non-metalsOnly Br and Cl pair are the non-metals from the given choices.

Taking into account the definition of ionic and covalent bonds,  the pair of atoms Br and Cl will share electrons when a bond is formed between them.

Ionic bond

An ionic bond is a type of chemical bond that occurs when one atom gives up an electron to the other, in order for both to achieve electronic stability.

This union normally occurs between metal and nonmetal elements with different electronegativity, which means that the elements have different capacity to attract electrons.

In other words, an ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

Covalent bond

On the other side, the covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule.

Covalent bonds are established between non-metallic elements, such as hydrogen H, oxygen O and chlorine Cl. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas. The shared electron pair is common to the two atoms and holds them together.

This case

In this case, considering that K, Li and Ba are metallic atoms and Cl, I and Br are non-metallic atoms, the pair of atoms Br and Cl will share electrons when a bond is formed between them.
