How does the weather caused by a warm front compare to the weather caused by a cold front?

A: A warm front brings fog, but a cold front brings clouds that form from dry air.
B: A warm front brings rapid changes in weather, but a cold front brings slow changes in weather.
C: A warm front brings widespread cloud cover, but a cold front brings intense sun coverage.
D: A warm front brings rain in humid air on occasion, but a cold front brings thunderstorms in summer.

Answers

Answer:

The weather caused by a warm from and a cold front compare by:

D. A warm front brings rain in humid air on occasion, but a cold front brings thunderstorms in summer.

A warm front is a phenomenon in which a warm air mass replaces a cold air mass, creating fog and rain on one occasion. While the cold front is the replacement of a warm air mass by a cold air mass changing the pressure and creating a thunderstorm in the middle of summer. The warm front happens in zones close to the equator and the cold fronts happen in almost every place.

Read the following chemical equations.

Reaction 1: 2KI + H2O2 2KOH + 12
Reaction 2: Cl2 + H2 → 2HCI

Which of the following statements is true for both the chemical equations?

A. I is oxidized in reaction 1 and Cl2 is oxidized in reaction 2.

B. I is reduced in reaction 1 and Cl2 is reduced in reaction 2.

C. I is oxidized in reaction 1 and Cl2 is reduced in reaction 2.

D. I is reduced in reaction 1 and Cl2 is oxidized in reaction 2.​

Answers

This problem is providing two reduction-oxidation (redox) reactions in which the oxidized and reduced species can be identified by firstly setting the oxidation number of each element:

Reaction 1: 2K⁺I⁻ + H₂⁺O₂⁻  ⇒2K⁺O⁻²H⁺ + I₂⁰

Reaction 2: Cl₂⁰ + H₂⁰ ⇒ 2H⁺CI⁻

Next, we can see that iodine is being oxidized and oxygen reduced in reaction #1 and chlorine is being reduced and hydrogen oxidized in reaction #2 because the oxidized species increase the oxidation number whereas the reduced ones decrease it.

In such a way, the correct choice is C.

Can anyone help me? I will try to give brainliest.

Answers

Answer:

Looking at the table, Silver is definitely the most conductible metal there. It has the lowest electrical resistivity which means it allows for an easier flow of electrons, and it also has a higher thermal conductivity which means it would exhibit a higher conductivity. Diamond has the highest thermal conductivity, but the electrical resistivity is extremely high and due to its giant covalent/tetrahedral molecular structure (being an allotrope of Carbon), electrons can't necessarily jump around. Diamond wouldn't be a conductor at all.

The most simplest composition and structures provide a higher thermal conductivity. For example, with Diamond, we know that it is a structure made of covalent bonds of carbon, so its thermal conductivity is high.

Answer:

Q1

Copper

Explanation:

Copper is a good conductor of electricity, its resistance is high, and its chemical activity is weak

Q2

The thermal conductivity of a specific material is highly dependent on a number of factors. These include the temperature gradient, the properties of the material, and the path length that the heat follows.

In one to two sentences, explain how to compare the strength of electrostatic forces between molecules in salt water to the strength of electrostatic forces between molecules in freshwater. Include a description of the data to be collected and how that data would allow one to draw conclusions about the relative strengths of the electrostatic forces in the two substances.

Answers

Answer:

-Salts are composed of ions that form a tightly packed and ordered network, which is called a crystal lattice, and it is held together by ionic bonds.

Explanation: salts are ionic compounds, which are composed by oppositely charged ions (cations and anions) which are bonded each other by ionic bonds, in an ordered arrangement, often a crystalline solid.

-When a salt is added to a polar solvent like water, the ions interact with the solvent molecules via ion-dipole forces, which overcome the forces originally holding the ions together.

Explanation: the molecules of a polar solvent are dipoles because they have dipolar momentum (a difference in charge due to a electronegativiy difference). When a salt is dissolved in a polar solvent, it dissociates in ions. So, the resulting interactions between these species are ion-dipole forces.

-The ions are then isolated and stabilized in solution via these interactions, and when this occurs for most of the salt compound, it is considered soluble in that solvent.

Explanation: the ions in solution are surrounded by solvent molecules which stabilizes them. A salt which is enterely dissolved in a solvent is soluble in that solvent.

-Due to the nature of the interaction between ions and solvent molecules, a concentration of ions can be dissolved higher in water than in alcohol.

Explanation: water molecules have unique properties that make water an universal solvent. Due to these properties and its polarity, water can dissolve larger quantities of salt than other polar solvents such as alcohol.

The electrostatic force in water without salt  is stronger as compared to the  water due to the presence of free electrons.

In water hydrogen bonding is present that is the only kind of  electrostatic force present in the water. In water containing salt sodium and chloride ions are present which conduct strong electrostatic force. A static meter is ideal for measuring the  of liquids. It measures the charge on the liquid. Hence, the electrostatic force in salt water is stronger as compared to the  water due to the presence of free electrons.

30g of glucose and 20 g common salt is dissolved in 500 mL of water to make solution. Calculate the concentration of a (a) glucose and (b) common salt in terms of mass by mass percentage of the solution. (Density of water = 1 g/mL)​

Answers

Answer:

The answer of a is 5.45% and b is 3.64%

Explanation:

Density of water = 1 g/mL

∴ Mass of water (solvent) = 500 g

Mass of solute (glucose) = 30 g

Mass of solute (common salt) = 20g

Mass of solution = (30 + 20 + 500) g = 550 g

a.)

Mass percentage of solution for glucose

= Mass of solute (gucose)/Mass of solution × 100

= 30/550 x 100

= 5.45 %

b.)

Mass percentage of solution for common salt

= Mass of solute (common salt)/Mass of solution × 100

= 20/550 × 100

= 3.64 %

Thus, The answer of a is 5.45% and b is 3.64%

The molar mass of water (H2O) is 18. 0 g/mol. A sample of water has a mass of 18. 0 g. How many moles of water are contained in this sample? 1. 00 18. 0 36. 0 324.

Answers

1 mole of water is contained in a sample of water that has a mass of 18.0 g.

HOW TO CALCULATE NUMBER OF MOLES:

The number of moles of a substance can be calculated by dividing the mass of that substance by its molar mass.

no. of moles = mass ÷ molar mass

According to this question, a sample of water has a mass of 18.0g. The number of moles is calculated as follows:

no. of moles of H2O = 18.0g ÷ 18g/mol

no. of moles of H2O = 1mol

Therefore, 1 mole of water is contained in a sample of water that has a mass of 18.0 g.

how would you expect the solubility of barium sulfate in pure water to compare to its solubility in 0.10 m nacl

Answers

Answer:

barium sulfate is insoluble (unable to dissolve) in water.

the general equation for the reaction between solid barium sulfate and nacl solution is this:

BaSO4 (s) + 2NaCl (aq) --> BaCl (aq) + Na2SO4 (aq)

to sum this up, to compare the solubility,

1. barium sulfate cant dissolve in pure water.

2. barium sulfate dissolves in nacl solution to give aqueous (aq) barium chloride (bacl) and aqueous sodium sulfate (na2so4), as shown in the equation above.

good luck!

The solubility of barium sulfate in pure water to zero as compare to the solubility in NaCl solution.

What is solubility?

Solubility is a property of any substance that defines how easily can be any substance will get dissolved or show dissolution.

Barium sulphate is insoluble in water beacuse it has higher lattice energy as well as higher size of cations & anions as compare to water, due to which water is not able to attract these ions towards itself affectively.Barium sulphate is soluble in the NaCl solution as this solution having ions which have more power to attract the ions of barium sulphate and show dissolution. Chemical reaction for this will be represented as:

         BaSO₄ (s) + 2NaCl (aq) → BaCl (aq) + Na₂SO₄ (aq)

Hence, barium sulphate is insoluble in water.
