In addition to interhalogen compounds, many interhalogen ions exist. Would you expect interhalogen ions with a 1+ or a 1- charge
VMariaS [17]

There is one electron in the valence shell of every halogen. Two halogen atoms join together to form a covalent connection (sharing one electron each). Thus, inter-halogen compounds with 1+ or a 1- charge contain an even number of atoms.

An interhalogen compound is a molecule with no atoms from any other group of elements and two or more different halogen atoms (fluorine, chlorine, bromine, iodine, or astatine). The majority of interhalogen chemicals are binary (composed of only two distinct elements).

a new weight-loss fad claims that you can reduce your mass simply by traveling to the Moon where gravity is weaker. why is this
Lilit [14]
Your mass can never change no matter where you are since mass is the amount of matter you contain.  By going to the moon, you do become lighter due to the weaker gravity but the amount of matter that you are made of (your mass) does not change.

I hope the helps.  Let me know if anything is unclear.

Given the balanced equation representing a
fredd [130]

From the coefficients of the equation, we see that for every 4 moles of aluminum consumed, 3 moles of oxygen are consumed.

So, the answer is (12/4)(3) = 9 moles.

Rank these acids according to their expected pKa values.ClCH2COOHClCH2CH2COOHCH3CH2COOHCl2CHCOOHIn order of highest pka to lowes
Ilia_Sergeevich [38]

Answer:

CH₃CH₂CH₂COOH > CH₃CH₂COOH > ClCH₂CH₂COOH  > ClCH₂COOH

Explanation:

Electron-withdrawing groups (EWGs) increase acidity by inductive removal of electrons from the carboxyl group.

Electron-donating groups (EDGs) decrease acidity by inductive donation of electrons to the carboxyl group.

  • The closer the substituent is to the carboxyl group, the greater is its effect.
  • The more substituents, the greater the effect.  
  • The effect tails off rapidly and is almost zero after about three C-C bonds.

CH₃CH₂-CH₂COOH —  EDG —                         weakest —  pKₐ = 4.82

      CH₃-CH₂COOH — reference —                                     pKₐ = 4.75

  ClCH₂-CH₂COOH — EWG on β-carbon— stronger —     pKₐ = 4.00

           ClCH₂COOH — EWG on α-carbon — strongest —  pKₐ = 2.87
