How many electrons are being shared between the two carbon atoms in the covalent compound ethyne? Ethyne has the structure: H−C≡C−H
Answers
Answer:
Three lines between the carbon atoms in the Lewis structure represent three covalent bonds. Each covalent bond is a shared pair of electrons, hence there are six electrons being shared between the carbon atoms in ethyne.
The number of electrons that are being shared between the two carbon atoms in the covalent compound ethyne is six.
What are covalent bonds?Covalent bond are formed by the sharing of electrons between two atoms.
In ethyne molecule two carbon atoms are present and between two carbon atoms three covalent bonds are present. And each covalent bond is formed by the sharing of two electrons. So three covalent bonds are formed by the sharing of 6 electrons.
Hence in ethyne 6 electrons are being shared.

The answers are in the picture. this us the question, An increase in carbon dioxide production has led to an increase in global temperatures, which is causing glaciers to melt faster. If this trend continues, how will animals living in the polar regions be affected?
Answers
Answer:
D
Explanation:
because if there is no land for them they wont survive in only water
The increase in global temperature melts the ice in polar regions. This worsely affects the animals living there. Hence, they will migrate to other areas but this is in fact not possible for their adaptation in other areas and they may subject to extinction.
What is global warming ?Global warming is the rise of temperature of earth surface all over the world. The significant reason for global warming is green house effect. Gases like carbon dioxide, methane gas etc. are intensely absorbing temperature that is radiating back from earth.
Hence, these gases are increasing the atmospheric temperature in earth. Global warming have very serious impacts that going up to the major discussion to solve nowadays.
The melting of polar icebergs and rising of sea level definitely leads to the extinction of animals living in polar region. They cant be adopted to other regions and migrating to other areas does not save them. Hence, they will extinct from earth. Therefore, option d is correct.

ANOTHER HELP OVER HEREEEEEE PLSSSSSSS
Answers
The declaration made in the image's results indicates that a chemical shift has taken place. There occurs the creation of gas.
What occurred when you put vinegar in the water?This occurs as a result of vinegar's composition of acetic acid and water. Acetic acid and water molecules create robust connections. These bonds cause the molecules inside the solution to move more slowly than those in pure water, hastening the freezing of the solution.
Briefing:A cup of vinegar and a cup of warm water are the basic components of the vinegar cleaning solution. Grease as well as hard water stains are easier to remove with warm water. It may be best to combine the vinegar and distilled water rather than tap water when filling a spray container that will be used often.
To create a chemical reaction, what can you combine with vinegar?A chemical reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) results in the production of salt (sodium acetate), water, and carbon dioxide gas.

An equimolar mixture of X (g) and Y (g) is placed inside a rigid container at constant temperature. The particle diagram above represents the changes that occur over time. Based on the particle
diagram, which of the following best predicts whether or not the system has reached equilibrium by 300 s?
a. It is not possible to determine that the system has reached equilibrium by 300 s because the stoichiometry of the reaction is not known.
b. it is not possible to determine that the system has reached equilibrium by 300 s because the amounts of X, Y, and XY have continued to change
c. The system has reached equilibrium by 300 s because the rate of formation of XY is constant
d. The system has reached equilibrium by 300 s because the rates of consumption of X and Y are equal
Answers
Answer:
B
Explanation:
t= 300s has more XY than t=200s, which means that it continues to change
*i think
The system has been predicted to be not possible to reach equilibrium as changing X and Y concentration. Thus, option B is correct.
Equilibrium has been described as the condition in the reaction mixture, when the concentration of the product and the reactant are equal.
The given reaction has been represented as:
[tex]\rm X+Y\rightarrow\;XY[/tex]
Reaction mixture at 300 sThe given reaction has been represented as, with the increase in time, there has been the consumption of the reactant and the formation of product.
The concentration has been continuously changing with time. Thus, the determination of the equilibrium has been difficult with changing X and Y concentration.
Thus, option B is correct.

What is an atom?
An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
