How does a paper bag wrapped around a hot water bottle create convection?

How does a paper bag wrapped around a hot water bottle create convection?

Heat is a form of energy. You need energy to heat something up: for example, a cup of tea. To make your tea you probably use energy from electricity or gas. However, once your tea is hot, it won't stay hot forever. Just leave the cup of tea out on the table for a while, and you already know that it will become cooler the longer you wait. This is due to a phenomenon called heat transfer, which is the flow of energy in the form of heat. If two objects have different temperatures, heat automatically flows from one object to the other once they are in contact. The heat energy is transferred from the hotter to the colder object. In the case of the tea, the heat of the liquid is transferred to its surrounding air, which is usually colder than the tea. Once both objects reach the same temperature, the heat transfer will stop. Heat transfer via movement of fluids (liquids or gases) is called convection.

Another type of heat transfer is conduction, in which energy moves through a substance (usually a solid) from one particle to another (unlike in convection where it’s the heated matter itself that moves). A pot handle getting hot would be an example of conduction.

Explanation:

1.  H2O

Lewis Dot:  

See the attachment.

Note the б+ and б- signs on the H and O atoms, respectively.  Those represent the slightly positive and slightly negative sides of the water molecule.  Those slight charges on a single water molecule are attracted to their opposite charges on neighboring H2O molecules, as shown in the graphic.  This interaction is what gives water it's cohesive properties.

3.  The property of cohesion describes the ability of water molecules to be attracted to other water molecules. which allows water to be a "sticky" liquid.

The hydrogen bonds are attractions of electrostatic force.  They arise due to the difference in charge between the slightly positive hydrogen ion and the slightly negative oxygen ion. Hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond, and it is what gives water it's cohesiveness, or ability to support water spiders, paper clips, and produces a loud noise in the event of a belly flop in a pool (including the yelp from the swimmer).

4.  I'm not sure what is being asked for the two blanks.  Water is polar and dissolves salts (ionic compounds) and hydrophilic molecules (water-loving molecules).

plz help

Answers

It is TRUE that mass is indeed the gravitational force that pulls on earth

Answer:

I believe the answer is false

Explanation:

Earth's gravity comes from all of its mass. All the mass makes a combined gravitational pull on all the mass in an object. If you were on a planet with less mass than Earth, you would weigh less than you do here. Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. Mass is not the gravitational pull on the earth.

What is a chemical reaction?

In a chemical reaction, reactants undergo a chemical reaction and transform into products through a chemical process. For instance, when humans breathe in oxygen, it combines with glucose to create carbon dioxide, water, and energy.

Another sign that a chemical reaction has taken place is a change in color. If two solutions are combined and a color change occurs that is not just the effect of diluting one of the reactant solutions, a reaction has taken place. A solid and a liquid combined may also result in a change in color.

Therefore, the correct option is D. The addition of chlorine gas to a solution of potassium iodide.

How many moles of nitrogen dioxide, NO2, are present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L

Answers

There are 0.436 moles of nitrogen dioxide, NO2, present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L.

IDEAL GAS LAW:

The number of moles of nitrogen dioxide (NO2) in this question can be calculated by using the ideal gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)V = volume (L)T = temperature (K)R = gas law constant (0.0821 Latm/molK)n = number of moles

According to the reaction conditions given in this question;

P = 2.46 atmV = 4.8Ln = ?T = 330K

2.46 × 4.8 = n × 0.0821 × 330

11.81 = 27.093n

n = 11.81 ÷ 27.093

n = 0.436mol

Therefore, there are 0.436 moles of nitrogen dioxide, NO2, present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L.

What products are obtained by the electrolysis of CuSO4 solution using copper electrode ? Show with help of chemical reaction.​

Answers

Answer: The products will be copper and oxygen.

Explanation: Copper electorde is an active electrode so it constantly takes part in the electrolysis. Cathode is a pure copper negative electrode and anode is a impure copper positive electrode. So the copper present in the solution, along with the copper present in the anode will come off and go to the cathode. As a result, cathode gains copper. And the remaining impurities settle down in the bottom.

In the anode, oxygen will be given off because according to the order of discharge, if SO4 is present then the ions will stay in the solution and oxygen will be released. So at the end, solution of SO4 and H2O will be remaining while copper and oxygen is extracted.

The half equations are-

Cathode: Cu2+ + 2e- = Cu

Anode: Cu + 2e- = Cu2+

Something you might not know: The solution in electrolysis turns blue when copper goes to the cathode. So copper electrodes are also used in electroplating.

How is a chemical equation different from mathematical equation?
Only chemical equation uses + sign
Only chemical equation uses arrow instead of = sign
Only chemical equation has numbers
Only chemical equation has minuses

Answers

Answer:

Only chemical equation uses arrow instead of = sign

Answer:

Only chemical equation uses an arrow instead of a = sign.

A chemical equation depicts a chemical reaction by utilising chemical formulae and symbols to depict the reactants, products, and chemical changes that take place. In a chemical equation, the arrow indicates the direction of the reaction and is commonly depicted as a single arrow pointing from the reactants to the products. In contrast, the equals sign (=) is commonly used in mathematical equations to indicate that two expressions have the same value.

While numbers are used to indicate the relative proportions of reactants and products and minus signs are used to indicate reactants or products in the form of ions, the arrow is the most distinguishing feature that distinguishes chemical equations from mathematical equations.

9. What is G for the reaction below – calculate it from the ^o ?

Fe (s) + Au3+ (aq) -> Fe3+ (aq) + Au (s)

Answers

The free energy change of the reaction; Fe (s) + Au3+ (aq) -> Fe3+ (aq) + Au (s) is calculated to be -443.83KJ/mol.

For the reaction shown in question 7, we can divide it into half equations as follows;

Oxidation half equation;

6 Al (s) -------> 6Al^3+(aq) + 18e

Reduction half equation;

3Cr2O7^2-(aq) + 42H^+(aq)   + 18e -----> 6Cr^3+(aq) + 21H2O(l)

The balanced reaction equation is;

6Al(s) + 3Cr2O7^2-(aq) + 42H^+(aq)   -----> 6Al^3+(aq) + 6Cr^3+(aq) + 21H2O(l)

The E° of this reaction is obtained from;

E° anode = -0.04 V

E°cathode = +1.50 V

E° cell = +1.50 V - (-0.04 V) = 1.54 V

Given that;

ΔG° = -nFE°cell

n = 3, F = 96500, E°cell = 1.54 V

ΔG° = -(3 × 96500 × 1.54)
