Answer:
group 1
Explanation:
chlorine donate electron
Chlorine will more likely to form bonds with the elements of group 1 as it has 7 valence electrons.
Chlorine element:Chlorine is an element that is present in group 17. This family is also known as the Halogen family. The elements of this group will have seven electrons in their outermost shell. It has only one electron less to attain a stable noble electron configuration.
Thus, it will form bond more readily with Group 1 that has only one electron in its outermost shell.
Thus, correct option is a.

Which statement is correct about the law of conservation of energy?
Energy is created when water freezes.
Energy is destroyed when sugar is burned.
Energy stays inside molecules permanently.
Energy is transferred when atoms are rearranged.
Answer:
Energy is transferred when atoms are rearranged
Explanation:
Breaking bonds between atoms need energy. When new bonds are formed, energy is released
The law of conservation of energy is energy isn't created or destroyed
A and B are wrong because there is creation or destruction of energy
C is wrong because energy can be transferred (think touching a hot stove with your finger. heat is transferred from the stove to your finger OUCH!)
D is correct because the energy is still there, but in a different form

Explanation:
Hello!
i. In this case, since the given chemical reaction is exothermic due to the negative change in the enthalpy of reaction, we infer that according to the mentioned principle, by lowering the temperature the reaction will shift rightwards and therefore the yield is increased; thus, you need a lower temperature than the specified.
ii. In this case, since the reaction has less moles at the products side, according to the mentioned principle it'd be necessary to rise the pressure in order to increase the yield, since the increase of pressure favors the reaction side with the fewest number of moles.
Best regards!

Consider the reaction H2(g) + I2(g) Double headed arrow. HI(g) with an equilibrium constant of 46.3 and a reaction quotient of 525. Which direction will the system shift to?
Answer:
The reaction shifts to the left.
Explanation:
Equilibrium constant (K) = 46.3
Reaction Quotient (Q) = 525
The relationship between Q and K with their implications are given as;
K = Q (No net reaction)
K > Q (Reaction shifts to the right)
K < Q (Reaction shifts to the left)
Since in this question, Q (525) > K (46.3)
The reaction shifts to the left.

Two plants growing close to one another are competing for resources. Which resource are they NOT likely to compete for? Choices A-Water B-Soil and nutrients C- Carbon dixoide
Answer: the resource which they are not likely to compete for is CARBONDIOXIDE. The correct option is C.
Explanation:
Competition may be defined as the a negative effect on plant growth which occurs when there is reduction in the availability of resources.
During the growth of plants, there are several resources that affects it's growth and maintenance. These resources include:
--> soil nutrients,
--> water,
--> carbondioxide and
--> sunlight
Since plants are autotrophs, that is, they manufacture their own food through the use of inorganic raw materials such as water and carbondioxide in the presence of sunlight, there may exist some level of competition for these resources when there is lack of space.
But plants are NOT likely to compete for carbondioxide because the atmospheric pool of carbondioxide is large and well mixed, therefore it won't be affected by lack of space between the two plants. Unlike the other main resources such as soil nutrients and water which are highly competed for and can determine the distribution of plants in an ecosystem.

Answer: The amount of water produced is 9.3 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
[tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]
mass of reactants = mass of methane + mass of oxygen = 22.5 g + 35.7 g = 58.2 g
mass of products = mass of carbon dioxide + mass of water = 48.9 g + mass of water
48.9 g + mass of water = 58.2 g
mass of water = 9.3 g

Please answer the following questions:
Why does Na have only one dot?
Why do none of these diagrams show more than 8 dots?
What relationship do you notice between the dots in these two charts?
The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why? (Hint: Octet Rule (Links to an external site.))
Hello! Here's the answer I was able to come up with:
Why does Na have only one dot?
Sodium, or Na, has only one valence electron. (This makes the atom tend to participate in ionic bonding and "give" its single valence electron to an atom like chlorine.)
Why do none of these diagrams show more than 8 dots?
It is physically impossible for an atom to have more than 8 electrons in its valence layer, according to the Octet Rule.
What relationship do you notice between the dots in these two charts?
The dot diagram for each element represents the number of electrons each element will have in its outermost, or valence, shell. (2-8-8)
The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why?
An atom can have a maximum of two electrons in its innermost layer. Hydrogen and helium have only one and two electrons, respectively, so they don't have enough electrons to actually have more than one layer. Therefore, their outermost layer is, in fact, their only layer. This is why the number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table.

Which molecule will undergo only London dispersion forces when interacting with other molecules of the same kind? a.HCl b.C2H5OH c.NH3 d.CH4
Answer:
CH4
Explanation:
London dispersion forces are a type of force acting between atoms and molecules that are normally electrically symmetric; that is, the electrons are symmetrically distributed with respect to the nucleus. They are part of the van der Waals forces(Wikipedia). It is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction(Chem Purdue).
If we consider HCl, C2H5OH and NH3, we will discover that they all have polar bonds. Consequently, dipole - dipole interaction as well as hydrogen bonds exist between their molecules.
CH4 is nonpolar. Being a nonpolar molecule, the only possible intermolecular interaction forces between its molecules is the London dispersion forces.
Predict the shape of the molecule.
B. trigonal planar
A. linear
D. bent
C. tetrahedra

Answer:
Technically, dihydrogen monoxide.
Explanation:
You see, the International Union of Pure and Applied Chemistry, also known as IUPAC, hasn't seen a need to define a structural name for water yet.
Following the naming conventions, it should most likely be called "dihydrogen monoxide", but IUPAC has never officially defined this as the chemical name for water.
