Inert gas does not affect the equilibrium position:
It is because the partial pressures of the reaction components remain the same.
What is Inert Gas?
Under a given set of conditions, an inert gas is a gas that does not undergo chemical reactions.The noble gases (helium, neon, argon, krypton, xenon, and radon) were previously known as "inert gases" due to their perceived lack of involvement in any biochemical processes.Because inert gases are non-reactive, they do not affect equilibrium partial pressures and thus do not affect volume.An inert gas does not react with the reactants or products; it does not change the concentration of the products and reactants. Furthermore, because the volume is constant, the concentrations are unaffected. As a result, this does not affect equilibrium.The equilibrium position won't change if an inert gas is added. A volume change won't change the equilibrium position if the total moles of gas in the products and reactants are the same. When the volume is reduced, the process changes to create fewer moles of gas.

In the lab, you are given a metal ball. You measure the mass of the ball to be 28 g. You place the ball in a graduated cylinder and the water level increases from 28.2 mL to 31.4 mL. What is the density of the metal ball? (round you answer to the nearest hundredth)
Answer:
Density = 8.75ml
Explanation:
Density = Mass / Volume
In this problem ...
Mass = 28 grams
Volume = 31.4ml - 28.2ml = 32ml (water displacement also)
∴Density = mass /volume = 28g/32ml = 8.75g/ml
Plants cells also gain energy through cellular respiration.

Explanation:
What category of organisms makes up the largest percent of the the fossils discovered? A. Land animals B. Marine animals C. Microorganisms
Answer:
Marine animals
Explanation:
A fossil is any remains of ancient life. Fossils can be body fossils, which are remains of the organism itself or trace fossils, such as burrows, tracks, or other evidence of activity(Lumen Learning).
Fossils of land animals are less common because they may not have been buried. However, land organisms may become buried underneath by mudslides or ash from a volcanic eruption, or covered by sand in a sandstorm.
Marine fossils are more common owing to quick burial. Marine animals that die near a river delta may be buried by sediment carried by the river. A storm at sea may shift sediment on the ocean floor, covering and helping to preserve skeletal remains(Lumen Learning).

Can someone please explain to me what a Ecologist does for a living? (Or daily in their career?)
ecologists look at relationships between nature, studying the interactions between humans, animal and plants.
Answer:
Ecologists focus on the relationship of organisms within their environment. Ecology is a branch of biology (biology is the study of life). Given the broad scope of ecology, there are multiple sub-disciplines that an ecologist can choose to focus on. Since all living things (plants, animals, microbes) depend on other living things and a healthy environment to survive, ecologists may specialize in one aspect of an ecosystem. Examples include terrestrial (land), aquatic (water), applied (concepts and principles of ecology), conversation (management of biodiversity), and evolutionary (evolution).

What is the boiling point for butane?
Answer:
30.2°F
Explanation:
Butane, the liquid that can be seen inside a transparent lighter, boils at a temperature slightly under the point at which water freezes. So why doesn't the butane in the lighter boil? Butane does indeed boil at about a degree below 32 degrees Fahrenheit, but this is true only at normal atmospheric pressure. (:

Use the following chemical equation to answer the question. 4K(s) + O2(g) → 2 K2O(s). If a staff member at a laboratory has 12.0 grams of potassium metal, what is the theoretical yield of potassium oxide that the scientist could potentially produce from the reaction with oxygen gas?
A) 9.96 grams of K2O
B) 14.5 grams of K2O
C) 28.9 grams of K2O
D) 57.8 grams of K2O
Answer:14.5 grams of K2O
Explanation:
4K(s) + O2(g) → 2 K2O(s). If a staff member at a laboratory has 12.0 grams of potassium metal, 14.5 grams of K2O is the theoretical yield of potassium oxide that the scientist could potentially produce from the reaction with oxygen gas. Therefore, option B is correct.
What is theoretical yield ?The yield of a reaction is used to represent how much of a product is produced from that reaction. The theoretical yield is the quantity of product that stoichiometry predicts will be produced, whereas the actual yield is the amount that is actually produced.
Divide the ratio by the limiting reactant's molecular weight. The answer is the theoretical yield of the desired product in moles.
It is useful to know how much product will be created with specific reactant amounts before carrying out chemical reactions. The theoretical yield is what is meant by this. This method can be applied to determine the theoretical yield of a chemical reaction.
Thus, option B is correct.

If you tested two samples of a particular pure substance, what would you find?
Answer:
The properties of a pure substance can be used to determine whether a sample is a pure substance or mixture because the characteristic properties of matter can be used to identify a sample. The result is a mixture called a composite.
Explanation:
Pure substances contains their own molecules only and not any impurity. Thus, when we tested it only shows the properties of its own.
What are pure substances?Pure substances are substances containing its pure composition without any impurities. For example water, fruits, acids etc. are pure substances and they does not have a combination other substances.
Mixtures are the combination of two or more pure substances, and the can be heterogenous or homogenous. Whereas, pure substances homogenous only thus forming only one phase.
When we tested mixtures qualitatively, they shows the properties of each individual components in it. Whereas, pure substances give inly its own characteristics.
