Answer:
At the cathode in an electrolytic cell, ions in the surrounding solution are reduced into atoms, which precipitate or plate out on to the solid cathode. The anode is where oxidation takes place, and the cathode is where reduction takes place. The anode is defined as the electrode where oxidation occurs. The cathode is the electrode where reduction takes place. ... At the cathode, the metal ion in the solution will accept one or more electrons from the cathode, and the ion's oxidation state will reduce to 0. This forms a solid metal that deposits on the cathode.

Your friend tells you the statute has a dull luster. What does luster tell you about a mineral?
o the color it makes when rubbed against a hard surface
O how hard the mineral is
O what color the mineral is
O how light is reflected from the surface of the mineral
Answer:
How light is reflected from the surface of the mineral.
Explanation:
To know the the correct answer to the question, we must bear in mind the meaning of luster.
Luster simply means the shining properties of a substance when light ray fall on them.
Thus, considering the question and the options given above, luster simply indicates how light is reflected from the surface of the mineral.

Explain specific heat in your OWN words. (2pts) Explain the equation. (1pt) Give an example of your understanding of the concept that we encounter on a daily basis. (3 pts.)
Answer: The specific heat is the amount of heat per unit mass that is essential for raising the temperature of heat by one degree Celsius. Equation is the symbolic reaction of a chemical reaction in the form of symbols and formulas, where the reactant is written on the left side and the product is written on the right side.
We encounter a lot of things in our daily life that we love and also hate. What I have faced a lot is my nail tags that happens to me a lot and hurts too. And I love dipping biscuits in tea and that never happens at once because a single biscuit is too big for the cup. Hence, I have to break it and dip. Ugh

Which metalloid has three valence electrons? boron arsenic silicon lithium
HElp PLEase
Answer:
Boron
Explanation:
First, locate the metalloids on the periodic table. (First picture) The metalloids are in the yellow section. Next, remember that the group your element is in determines its valence electrons. For example, group 17/7A has 7 valence electrons. Look at the group numbers above each column on the periodic table to find out which metalloid is the answer. In this case, we need to look at 13/3A since we know that this metalloid has three valence electrons. Not all periodic tables will be labeled with the 3A part, so remember that groups 13 and over have the amount of valence electrons after you take out the one in front. For example, group 16 has 6 valence electrons because I removed the one in front of it. Now your options should be limited down to boron because we know that it is in the yellow section in group 13.
Answer:
the answer is boron

Two students are planning an investigation to determine if ionic or covalent bonds have stronger intermolecular forces. They are using salt (ionic), sugar (polar covalent), and moth balls (nonpolar covalent). Which property below would be the LEAST helpful in determining what bond type has the strongest intermolecular forces?
Flammability
Solubility in water
Conductivity in water
Melting Point
Answer:
conductivity in solid state/ in water
Explanation:
conducitvity in water state would be least helpful when trying to determine the bond type that has the strongest intermolecule force, becuase they (salt and water) both would dissolve in water the same.
The property that will be least helpful in the determination of the bond type that has the strongest intermolecular forces is C. Conductivity in water.
It should be noted that the students wanted to investigate whether ionic or covalent bonds have stronger intermolecular forces.
In order to carry out the investigation, salt, sugar, and molar balls are used. Based on this, the property that is required for the investigation will be flammability, solubility in water, and the melting point.
The conductivity in water isn't required.

What can you do to help reduce Acid Rain? List 5 ways.
Help me yall!! Imao
Answer:
- to produce energy without using fossil fuels instead using renewable sources solar and wind power.
- reduce the amount of sulfur dioxide released from coal-burning power plants. One option is to use coal that contains less sulfur.
- install equipment called scrubbers, which remove the sulfur dioxide from gases leaving the smokestack.
- While one car alone does not produce much pollution, all the cars on the road added together create lots of pollution. Therefore, car manufacturers are required to reduce the amount of nitrogen oxides and other pollutants released by new cars. One type of technology used in cars is called a catalytic converter. This piece of equipment has been used for over 20 years to reduce the amount of nitrogen oxides released by cars.
- recycling is one way that is often use less energy than producing a new products from raw materials so the use of energy that obtain mainly from fossil fuel will be reduced and that reduced the emissions of toxic gases.
Decreasing the amount of sulphur dioxide power plants that burn coal emit and Using less sulfuric coal is one option to reduce acid rain.
What is acid rain?Acid rain, also known as acid precipitation and acid deposition, is a type of precipitation with a pH of 5.2 or below that results from the release of nitrogen oxides and sulphur dioxide (SO2) from human activities, primarily the burning of fossil fuels. Acid deposition can impair biodiversity and lower the pH for surface waters in acid-sensitive areas.
To reduce acid Rain following steps can be taken: Generate energy using renewable resources like solar and wind energy rather than fossil fuels. Decrease the amount of sulphur dioxide power plants that burn coal emit. Using less sulfuric coal is one option. Install machinery known as scrubbers to take sulphur dioxide out of smokestack gas emissions. New automobiles must emit fewer nitrogen oxides as well as other pollutants, according to regulations for automakers. One method that frequently uses less energy than creating new items from basic materials is recycling.
Therefore, decreasing the amount of sulphur dioxide power plants that burn coal emit and Using less sulfuric coal is one option to reduce acid rain.
