An ionic compound is a chemical compound dissociated into positive and negative ions, but globally neutral (it is a bond that us
Firdavs [7]

True

Explanation:

Ionic compounds are chemical compounds that dissociates into positive and negative ions and are globally neutral due to the charge balance. They are made up of metals and non-metals.

  • Ionic bonds are formed between two kinds of atoms having a large electronegativity difference.
  • It is usually between metals and non-metals.
  • The formation of this bond type involves the transfer of electrons from the less electronegative atom such that the two kinds of atoms now have completely filled outer shell like the noble gases.
  • This transfer makes the metal positively charged while the non-metal becomes negatively charged.
  • The atoms forms ions that are oppositely charged.
  • The charges are balanced out leaving a net neutral compound.
  • The electrostatic force of attraction between these ions is the ionic or electrovalent bond.

Please help...<br> CaS cation and anion<br> ZnCl2 cation and anion<br> Cu2CrO4 cation and anion
Anvisha [2.4K]

Answer:Ionic compounds form when positive and negative ions share electrons and form an ionic bond. ... The positive ion, called a cation, is listed first in an ionic compound formula, followed by the negative ion, called an anion. A balanced formula has a neutral electrical charge or net charge of zero.

Explanation:Simple ions:  

Perchlorate ClO4- IO3-

Chlorate ClO3- BrO3-

Chlorite ClO2-  

Hypochlorite OCl- OBr-

When the pressure that a gas exerts
Savatey [412]
<h2>Hello!</h2>

The answer is:

When the pressure that a gas exerts  on a sealed container changes from

22.5 psi to 19.86 psi, the  temperature changes from 110°C to

65.9°C.

<h2>Why?</h2>

To calculate which is the last pressure, we need to use Gay-Lussac's law.

The Gay-Lussac's Law states that when the volume is kept constant, the temperature (absolute temperature) and the pressure are proportional.

The Gay-Lussac's equation states that:

\frac{P_1}{T_1}=\frac{P_2}{T_2}

We are given the following information:

We need to remember that since the temperatures are given in Celsius degrees, we need to convert it to Kelvin (absolute temperature) before use the equation, so:

P_1=22.5Psi\\T_1=110\°C=110\°C+273.15=383.15K\\T_1=65.9\°C=65\°C+273.15=338.15K

Now, calculating we have:

\frac{P_1}{T_1}*(T_2)=P_2\\\\P_2=\frac{P_1}{T_1}*(T_2)=\frac{22.5Psi}{383.15}*338.15=19.86Psi

Hence, the final pressure is equal to 19.86 Psi.

Have a nice day!
