Answer:

order the radicals by following general kanji stroke order rules

Explanation:

While you could use any ordering system you want as long as it's consistent, we recommend you order the radicals by following general kanji stroke order rules. That is, by starting in the top-left and working your way down to the bottom-right. It'll make writing easier, should you ever learn how to write by hand

Answer:

To make this work, you'll either need to: Learn the names of all the radicals first, before you even look at any kanji. This method feels slow at first, but overall it's probably going to take a similar amount of time compared to any other method.

In the Hall-Heroult process, a large electric current is passed through a solution of aluminum oxide dissolved in molten cryolit

natka813 [3]

The given question incomplete, the complete question is:

In the Hall-Heroult process, a large electric current is passed through a solution of aluminum oxide (Al,03) dissolved in molten cryolite (Na, Alts).re in the reduction of the Al, o, to pure aluminum. Suppose a current of 1800. A is passed through a Hall-Heroult cell for 37.0 seconds. Calculate the mass of pure aluminum produced Be sure your answer has a unit symbol and the correct number of significant digits.

Answer:

The correct answer is 6.2114 grams.

Explanation:

Based on the given question, the value of current or I have given is 1800 amperes, the time given is 37 seconds, and there is a need to find the mass of the pure aluminum generated in the process. Mass or weight can be determined by using Faraday's first law equation, that is, w = MIt/nF.

Here, M is the atomic mass, w is the weight of the substance deposited, t is time, I is current, n is the number of moles of the electron, and F is the Faraday's constant, which is 96500 C. In the process mentioned in the question, aluminum oxide is reduced to give rise to pure aluminum, and in the process 3 electrons are gained. So, the value of n will be 3. The M or the atomic mass of Al is 27 gm per mole. Now putting the values in the equation we get,

w = 27*1800*37 / 3*96500

w = 1798200 / 289500

w = 6.2114 grams

Hence, pure aluminum produced in the process is 6.2114 grams.

Melting is an endothermic process. Using the terms 'kinetic energy' and 'intermolecular forces', explain how the addition of ene

Helen [10]

Melting is a process where a solid such as ice turns into liquid or water. The molecules of ice slowly moves and becomes unstable as they gain energy. As this energy builds up, kinetic energy increases and the intermolecular forces react because of this energy.Thank you for your question. Please don't hesitate to ask in Brainly your queries.

Which statement describes the water gas particles in the air above the cup compared with the water liquid

Law Incorporation [45]

Answer:

The particles move faster and are far apart

Explanation:

A substance may exist in three states of matter; solid, liquid and gas.

In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.

In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.

In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.

Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.

For which salt is the aqueous solubility most likely to change by changing the pH of the solution?

Hoochie [10]

The salt whose aqueous solubility will most likely to change the pH of the solution is CaF2(aq).

The pH of a salt solution depends on the nature of the acid and base that forms the salt.

Salt of a weak acid and a strong base yields a basic solution
Salt of a strong acid and a weak base yields an acidic solution
Salt of a strong acid and a strong base yields a neutral solution.

Since HF is a weak acid, its salt CaF2 will be slightly basic when dissolved in water hence the pH of the solution is altered.
