4 0

Answer:

The oxidation reaction: Ni → Ni⁴⁺ + 4e.

The reduction reaction: 2Cl₂ + 4e → 4Cl⁻.

Explanation:

  • The mentioned reaction: <em>Ni + 2Cl₂ → NiCl₄.</em>
  • It is an oxidation-reduction reaction comes from two half reactions.

<em>The oxidation reaction:</em> in it Ni losses 4 electrons and is oxidized to Ni⁴⁺ according to the reaction:

<em>Ni → Ni⁴⁺ + 4e.</em>

<em></em>

<em>The reduction reaction: </em>every molecule of Cl₂ will gain 2 electrons and is reduced to 2Cl⁻ according to the reaction:

<em>2Cl₂ + 4e → 4Cl⁻.</em>

<em></em>

  • The summation of the two-half reactions will give the reaction:

<em>Ni + 2Cl₂ → NiCl₄.</em>

100.0 grams of sucrose (C12H22O11)is dissolved in 1.50 L of water. What is the molality?
Nitella [24]

Answer:

Molality = 66.67g/L

Explanation:

Mass of sucrose = 100g

Volume of water = 1.50L

Molality = mass of substance/ volume in L

Molality = 100 / 1.50

Molality = 66.67g/L

Molality of 100g of sucrose in 1.50L of water is 66.67g/L

Arrange these compounds by their expected boiling point. Highest boiling point Lowest boiling point CH3OH, CH3CI CH4.
PSYCHO15rus [73]

Answer: The given compounds are arranged according to decreasing boiling point as CH_{3}OH > CH_{3}Cl > CH_{4}.

Explanation:

The temperature at which vapor pressure of a substance becomes equal to the atmospheric pressure is called boiling point.

Stronger is the intermolecular forces present the atoms of a molecule more heat will be required by it to break the bond between its atoms. Hence, more will the boiling point of the molecule.

In CH_{3}OH (methanol), there is hydrogen bonding present which is a stronger force. So, it will have highest boiling point as compared to CH_{3}Cl and CH_{4}.

In CH_{3}Cl (chloroform), there is more electronegative atom attached (Cl) is attached to less electronegative atom (C and H). So, electrons are more pulled towards the chlorine atom. So, boiling point of  CH_{3}Cl is more than methane (CH_{4}).

Thus, we can conclude that given compounds are arranged according to decreasing boiling point as CH_{3}OH > CH_{3}Cl > CH_{4}.

Typically ____
MArishka [77]

Answer:

Protons

Explanation:

Typically protons cannot be removed from the atom. Removing protons from an atom will completely change the atom as it will become another element entirely.

In an atom, protons are held by strong nuclear forces.

  • Within an atom, protons are the positively charged particles.
  • Together with the neutrons, they are found in the nucleus of an atom.
  • The number of protons within an atom is the atomic number of the atoms and it determines the nature and type of atom it is.
  • Protons cannot be removed from an atom due to the strong binding force holding them together in place.
