For single bonds between similar types of atoms, how does the strength of the bond relate to the sizes of the atoms? Explain.

uysha [10]

When comparing single bonds between atoms of comparable types, the stronger the bond is, the bigger the atom, the weaker it is.

The length of the X-H bond lengthens while the strength of the bond shortens with increasing halogen size (F-H strongest, I-H weakest). When comparing single bonds between atoms of similar sorts, the larger the atom, the weaker the bond. It can be explained by the fact that less energy is required to break the bond the bigger the atom's atomic size. The force of attraction from the nucleus to the outermost orbit will be less for iodine since it has a larger atom than the other elements in the group.

Which law states that the entropy of the universe is always increasing?

vova2212 [387]

Second law of thermodynamics states entropy of the universe is always increasing. entropy always increases in a spontaneous process .

option B) second law of thermodynamics

for example if we keep a hot cup of coffee the heat is lost to surrounding and entropy( randomness increases) since it is a natural process entropy of universe increases.

The double replacement reaction

<h3>Further explanation</h3>

Given

Reaction if Na₂S + HCl

Required

Type of reaction

Solution

The double replacement reaction occurs when there is a displacement of the cations and anions of the reactants involved in the reaction to form two new compounds.

The general formula for this reaction :

AB + CD ⇒ AD + CB

At the bottom of the reaction, it is shown the number of atoms of each compound in the reactants and products which indicates the application of <em>the law of conservation of mass</em>, that the number of atoms in the reactants will be the same as the number of atoms in the product, so the reaction is said to be in a balanced state.

Every day on his ride to school, Max sees some sedimentary rock. He starts to wonder: Could material from this sedimentary rock

Sloan [31]

Material from this sedimentary rock ever forms igneous rock, <u>Option D. Yes, if the sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form </u><u>igneous rock.</u>

Sedimentary rocks are shaped from pre-existing rocks or pieces of soon-as-dwelling organisms. They form from deposits that collect on this planet's floor. Sedimentary rocks regularly have special layering or bedding.

Igneous rock, or magmatic rock, is one of the 3 primary rock kinds, the others being sedimentary and metamorphic. Igneous rock is shaped via the cooling and solidification of magma or lava. The magma may be derived from partial melts of existing rocks in either a planet's mantle or crust.

Every day on his ride to school, Max sees some sedimentary rock. He starts to wonder: Could material from this sedimentary rock ever form igneous rock?

A. No, igneous rock can only form out of other igneous rocks. Sedimentary rock cannot change into igneous rock.

B. No, igneous rock forms under Earth’s outer layer due to energy from Earth’s interior, but the sedimentary rock is only at Earth’s surface.

C. Yes, if the sedimentary rock is exposed to energy from the sun at Earth’s surface for a long enough time, it can melt into liquid rock and form igneous rock.

D. Yes, if the sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form igneous rock.
