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

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.

answer and unit.
Show Your Work
Answer:
v₂ = 39L
Explanation:
Given parameters:
Initial volume of gas = 20L
Initial temperature = 140K
Unknown:
Final volume = ?
Solution:
Since the standard temperature of any gas is 273K, the final temperature is this 273K;
Applying Charles's law:
[tex]\frac{v_{1} }{T_{1} }[/tex] = [tex]\frac{v_{2} }{T_{2} }[/tex]
v and T are volume and Temperature
[tex]\frac{20}{140}[/tex] = [tex]\frac{v_{2} }{273}[/tex]
v₂ x 140 = 20 x 273
v₂ = 39L

Which statement correctly describes a reaction in dynamic equilibrium? At dynamic equilibrium, the reactions stop and the amounts of reactants and products do not change. At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change. At dynamic equilibrium, the reactions stop but the amounts of reactants and products are changing. At dynamic equilibrium, the reactions continue and the amounts of reactants and products are changing.
Answer:
At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
Explanation:
At dynamic equilibrium, the reactions continue but according to the law of conservation of mass, the amounts of reactants and products don't change.
At dynamic equilibrium, the reactions takes place, however, the amount of reactants and products do not change.
• Dynamic equilibrium prevails once a reversible reaction takes place.
• In this the transition of the substances between the reactants and products takes place at equivalent rates, thus, there is no net change.
• The formation of products and reactants takes place at such a rate that the concentration of both stays the same.
• It is an illustration of a system in steady state, like in a closed system when reactions do take place, however, at such a rate that the composition of the mixture does not varies with time.
Thus, the statement, that is, at dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change is relevant.

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.
