Given substances f2, kr, cl2 and hbr rank them with respect to the highest boiling point?
Inessa05 [86]

The Hbr has highest boiling point followed by Kr , Cl_{2} and F_{2} .

The Hbr has  highest boiling point due to presence of intermolecular H-bonding that is hydrogen bonding.

The electronegativity of bromine is greater than hydrogen atom. The electronegativity difference hydrogen atom and bromine atom is high. So, due to this a positive dipole is generated at hydrogen atom and partial negative charge, these partial charge is called dipole. In a HBr molecule one H-atom attracted by Br-atom of another atom by force of attraction and this partial force of attraction is called H-bonding.

Other all given molecules are arrange according to its molecular mass because boiling points is directly proportional to the molecular mass of molecule.

Is Ca + O --> CaO a balanced chemical equation? Is it obeying the law of conservation of matter? Question 5 options: Yes it i
iren [92.7K]

Answer is: Yes it is balanced. It has the same number of Ca and O on both the reactant side and the product side.

According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.

There is one calcium atom atom and one oxygen atom on both side of reaction, so chemical reaction is balanced.

The pH of a solution that is formed by the neutralization of 1.0M H2SO4(aq) and 1.0 M KOH(aq) is closest to
pshichka [43]

Answer:

b) 7

Explanation:

The pH of a solution produced by the neutralization reaction between 1M of H₂SO₄ and KOH with 1M is closest to 7.

pH is a standard for measuring the acidity and alkalinity of a solution. A solution that is acidic will have a pH less than 7, a neutral solution will have pH of 7 and a basic solution will have pH greater than 7.

What is a neutralization reaction?

  • It is an acid-base reaction in which hydrogen and hydroxide ions combines to form water.
  • Also a salt results from the combination of the other ions.

In this reaction a base simply neutralizes an acid and the solution becomes neutral before it goes into completion.

Therefore, a neutral solution will have pH of 7 or close to it.
