How would you explain the Earth’s atmosphere?

The atmosphere is a thin layer of gases that surrounds the Earth. It seals the planet and protects us from the vacuum of space. It protects us from electromagnetic radiation given off by the Sun and small objects flying through space such as meteoroids.

So it's like a blanket protecting us but it has air hole/patches where sunlight can get through

Mike is conducting an experiment inside an Erlenmeyer flask, and he has the top of the flask sealed with a balloon to capture any gaseous products that may be produced. Is Mike’s experimental setup an example of a closed, open, or isolated system? Explain your answer in complete sentences.

This is a closed system, for it does exchange energy with the area around it. It will not exchange mass with the surrounding system due to being sealed, but it is not insulated at all.

Explain how matter is not created or destroyed when there are chemical and physical changes.

Matter is neither created nor destroyed during a chemical or physical reaction but changes from one form to another, for example when we burn wood this is a chemical reaction by burning the wood we are not destroying it we are just changing it  to a different form which is charcoal,  also melting ice is a physical reaction here we are changing the ice from solid to liquid (water).

QUESTION POSTED AT 17/10/2019 - 04:55 AM

The mass defect of a particular reaction resulted in the production of 5.50 x 10^15 joules of energy. What mass (if totally converted to energy) would correspond to this amount of energy? (1 J = 1 kg m^2/s^2) 1.83 x 10^8 kg 4.95 x 10^7 kg 6.11 x 10^-2 kg 1.64 x 10^-1 kg

Answer : The correct option is, 6.11\times 10^{-2}Kg

Explanation :

According to the Einstein equation, the energy is equal to the product of mass and the square of the speed of light.

The mathematical expression is :

E=m\times c^2

where,

E = energy  = 5.50\times 10^{15}J

c = speed of light = 3\times 10^8m/s

m = mass = ?

Now put all the given values in the above formula, we get the mass.

5.50\times 10^{15}J=m\times (3\times 10^8m/s)^2

m=6.11\times 10^{-2}Kg

Therefore, the mass defect would be, 6.11\times 10^{-2}Kg

QUESTION POSTED AT 17/10/2019 - 04:09 AM

Which statement explains why some elements decay and others do not? A)Elements that decay have fewer than 50 protons. B)Elements that decay have an equal number of protons and neutrons. C)Elements that decay have a proton to neutron ratio that is too high or too low. D)Elements that decay have too many electrons relative to the number of neutrons.

Answer: Option (C) is the correct answer.

Explanation:

Decay occurs when an atom is unstable. And an atom is unstable when it has great difference in the number of protons and neutrons or very low ratio of number of protons and neutrons.

This is because when the difference in the ratio of number of protons and neutrons is too high or low then forces will not be balanced. As a result, atom will become unstable causing decay. Whereas atoms in which ratio of protons and neutrons is similar then the atom will be stable and it will not decay easily.

Therefore, we can conclude that the statement elements which decay have a proton to neutron ratio that is too high or too low, best explains why some elements decay and others do not.

1. Create a diagram of your electroplating apparatus (an electrolytic cell). Then submit your drawing with the following terms labeled correctly. • anode • cathode • copper strip • battery • positive terminal • negative terminal • place where oxidation occurs • place where reduction occurs • electrolyte solution • coin (or nail) • direction of electron flow

A picture of the electroplating apparatus can be found attached. The nail (cathode) is completely submerged and that is where reduction happens. In the other side, the copper strip is (anode) where oxidation happens. The electron flow happens from the anode to the cathode. The positive charge of the battery is attached to the anode while the negative side is attached to the cathode.

Which term is defined as “anything that has mass and occupies space”?

Answer:

The answer is matter.

Explanation:

Matter is defined as everything that has a certain mass and occupies a place in space. Mass is defined as the magnitude that measures the amount of matter in a body. Volume is defined by the space a body occupies.

For example, a rock is considered matter because its mass is related to the number and class of particles that form it, and the space it occupies defines its volume.

Explain the relationship between sugars (glucose) and starches (carbohydrates). Use the terms, monomer and polymer, in your explanation.

Glucose is a monosaccharide, a monomer. Monomers combine t form polymers. Monosaccharide units combine to form polysaccharides or carbohydrates. Monosaccharide units polymerize through the glycosidic linkages to form carbohydrates. Starch is a polymer of glucose that is commonly found in plants. Starch is either found as amylase or amylopectin. Amylose is formed when α-Dglucose polymerizes through α(1→4) glycosidic linkage. Amylopectin is a branched polymer of α-glucose.

The table below provides percent ionization values to indicate the extent that 0.1M solutions of certain weak acids ionize in water according to the generic equation, HA + H2O Imported Asset H3O+ + A−. How are percent ionization values similar to equilibrium constant values? Explain your reasoning and identify which weak acid would have the smallest equilibrium constant. Weak Acid: 1. HNO2 2. HClO2 3. HCN Percent Ionization: 1. 6.2% 2. 28.2% 3. 0.007%

The acid dissociates as following:
HA + H₂O ↔ H₃O⁺ + A⁻
The value of percent ionization shows how much of HA molecules has dissociated, while the equilibrium constant value is calculated as follows:
K = [H₃O⁺] x [A⁻] / [HA]
The concentrations of H₃O⁺ and A⁻ depend on the amount of HA that has dissociated, same as the value of percent ionization, so the values of percent ionization and equilibrium constant are similar because they describe the same process. Comparing the values of ionization percent can be also used to determine if some acid is weak or strong, and to compare the strength of different acids, the same as equilibrium constant.

The smallest the values of ionization percent the acid is weaker.
Because 0.007% < 6.2 % < 28.2%, the strength of the acids increase as:
HCN < HNO₂ < HClO₂, which means that HCN is the weakest, while HClO₂ is the strongest of the listed acids.

Explain why organic reactions occur at a slower rate than inorganic reactions. What do chemists use to speed these reactions up? Why doesn't this change the products of the reaction?

The organic particles  are molecules. Because of strong covalent bonding in the molecule, organic compounds do not react quickly. Reactions with organic compounds are generally slower than inorganic reactions due to this fact. 

Increasing temperature speeds up a reaction because of there being more collisions and those collisions have higher energy. Also the high concentration of the chemicals, particle size and there being a suitable catalyst present. ( Though this process is harmful should it be used in modifying results in food grains and meats.)
