Answer:

[tex]v_{solute}=25mL[/tex]

Explanation:

Hello there!

In this case, according to the by-volume concentration of this solution, it is possible for us to use its mathematical definition as shown below:

[tex]\%v=\frac{v_{solute}}{v_{solution}}*100\%[/tex]

Thus, given the percent and the volume of the solution, we can solve for the volume of ethanol (solute) as shown below:

[tex]v_{solute}=\frac{\%v*v_{solution}}{100\% }\\\\v_{solute}=\frac{5.00\%*500mL}{100\%}\\\\ v_{solute}=25mL[/tex]

Explanation:

Molarity is the concentration of a solute (MgCl2) in our solution (water). Molarity tells us how many moles of a substance is per Liter. So to figure out Molarity we'll break it down to this formula: Molarity = [tex]\frac{moles}{Liter}[/tex].

We can get moles by converting it from grams -> moles by using the molar mass, which is measured in grams/mol, that is our stepping stone to moles.

The molar mass is the sum of all the substances in the compound, so you'll need to refer to the periodic table.

Molar mass: (24g Mg) + ( 2 x 35g Cl)= 94g

Moles of MgCl2: 45.7g MgCl2 x [tex]\frac{1 mol}{94g MgCl2}[/tex] = 0.49 mol MgCl2

1 kg of water = 1 L so we don't have to convert anything, we can just use 2.40 L.

Molarity of MgCl2: [tex]\frac{0.49 mol MgCl2}{2.40 L}[/tex] = 0.20M

There are approximately 1.204 x 10²⁴ oxygen atoms in 75 g of SO₃.

To calculate the number of oxygen atoms in 75 g of SO₃, we need to consider the molar mass of SO₃ and Avogadro's number.

The molar mass of SO₃ is calculated as follows:

Sulfur (S) = 32.07 g/mol

Oxygen (O) = 3 x 16.00 g/mol = 48.00 g/mol

Total molar mass of SO₍ = 32.07 g/mol + 48.00 g/mol = 80.07 g/mol

Next, we need to determine the number of moles of SO₃ in 75 g:

moles = mass / molar mass = 75 g / 80.07 g/mol ≈ 0.9369 mol

Since each molecule of SO₃ contains 3 oxygen atoms, we can calculate the number of oxygen atoms by multiplying the number of moles of SO₃ by Avogadro's number (6.022 x 10²³ atoms/mol) and then multiplying by 3:

Number of oxygen atoms = 0.9369 mol x 6.022 x 10²³ atoms/mol x 3 = 1.604 x 10²⁴ atoms

Therefore, there are approximately 1.204 x 10²⁴ oxygen atoms in 75 g of SO₃.

Answer:

30.34 atm

Explanation:

Using the general gas law formula;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

T = temperature (K)

R = gas law constant (0.0821 Latm/molK)

According to the information provided in this question,

n = 3mol

T = 35°C = 35 + 273 = 308K

V = 2.5L

P = ?

Using PV = nRT

P = nRT/V

P = 3 × 0.0821 × 308/2.5

P = 75.8604 ÷ 2.5

P = 30.34 atm.

Answer:

No.

Explanation:

Photosynthesis is the light dependent process which must occur for the plant to live. This process also requires water and carbon dioxide. If photosynthesis does not occur, the plant will die.

If plants do not receive enough water from the water cycle, photosynthesis can be affected, and in severe cases, it may not take place at all.

Photosynthesis requires water as one of its essential inputs, as it is used in the process of creating glucose and oxygen from carbon dioxide and light energy. Therefore, if plants do not receive enough water from the water cycle, photosynthesis can be impacted, and in severe cases, it may not take place at all.

Water is not only a raw material in photosynthesis, but it is also necessary for the regulation of plant cells' internal pressure, which is essential for maintaining their shape and structure. Without enough water, the cells' internal pressure decreases, causing them to shrink and lose their rigidity. This process is known as wilting.

Hence, water is essential for plant growth and photosynthesis, and if plants do not receive enough water from the water cycle, it can lead to wilting, stunted growth, and a reduction in photosynthesis.

Explanation:

Neither of them have more particles than the other because;

1 mole of any substance usually contains 6.022 × 10^(23) atoms/molecules/particles of that very same substance.

Thus, it will be the same value for Gold (Au) and water(H2O).

Answer:

Answer: Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Answer:

691.7 mmHg is the resulting pressure

Explanation:

Tha Gay-Lussac's law states that the pressure of a gas is directly proportional to its absolute temperature under constant volume. The equation is:

P1T2 = P2T1

Where P is pressure and T asbolute temperature of 1, initial state and 2, final state of the gas.

Computing the values of the problem:

T1 = 273 + 25 = 298K

P1 = 755.0mmHg

T2 = 273 + 0 = 273K

P2 = ?

755.0mmHg*273K = P2*298K

Answer:

mass = 102.69 g of sucrose

Explanation:

First, you need to use the correct expression of molality (m) which is the following:

m = moles / kg solvent    (1)

According to the exercise, we need to get the grams, in other words, the mass of the sucrose. To get the mass, we need the moles and molecular weight of sucrose and use the following expression:

moles = mass / MM    (2)

Now, if we replace (2) in (1) we have:

m = mass / MM * kg solvent   (3)

From here, we solve for the mass and then:

mass = m * MM * kg solvent (4)

Now, then density of water is 1 kg/L, so, the volume of the water will be the same as it's mass, and the molality is 3 m. The molecular weight of the sucrose is (according to several sources) 342.3 g/mol. Replacing all the data in (4) we have:

mass = 3 mol/kg * 0.1 kg * 342.3 g/mol

. Its nucleus is unstable.

Its nucleus is unstable. This characterizes a radioactive atom. Therefore, the correct option is option A.

The smallest parts of common stuff that can be separated without releasing electrically charged particles are called atoms. The atoms are divided into two sections. an electron cloud and an atomic nucleus. Atoms with an unstable nucleus and the potential for radioactive decay are referred to as radioactive atoms.

As only nuclei often experience decay and changes with electron configuration only come from nucleus configuration changes, the term "radioactive atom" is misleading. This isn't a rule, it must be said. As a parent nucleus needs capture any of its orbital electrons, the electron cloud also plays a significant role in the case of electron capture. Its nucleus is unstable. This characterizes a radioactive atom.

Therefore, the correct option is option A.

Answer:

There are now two oxygen atoms on the left and four on the right (in one N2O and three H2O's), so we balance the oxygen atoms by placing a 2 in front of the O2.

The numbers before atoms are the coefficients, and they are used to balance chemical reacions. In the provided example, number in front of O₂ is 3.

Note: Since I do not have the proposed reaction, I provided a random example.

A balanced chemical reaction is an equation in which the number and type of atoms are the same on both sides of the arrows.

Following the law of mass conservation, chemical equations should be balanced to ensure that all the reactants appear in the products.

This means that no new atoms appear, and no atoms disappear. The only thing that changes in a chemical reaction is the bond between atoms.

So each side of the equation must be equilibrated concerning the amount and type of atoms.

Coefficients are used to balance reactions. These numbers are located before each atom and indicate the number of units present in the formula.

I do not have the proposed reaction, but I will provide an example using O₂.

Reactants ⇒ 4 Al and 3 O₂

                     3 O₂ = 6 O

Products ⇒ 2 Al₂O₃

                    2 Al₂ = 4 Al

                    2 O₃ = 6 O

On each side of the equation we have 4 Al and 6 O. The only thing that changes are the bonds between atoms.

In this case, the coefficient of O₂ is 3.
