Please help me with this, thank you so much

I can’t answer the exact thing, but I know how to do it. One of the nitrogen bases always pairs with a different one, so once you know what pairs with what you just write it down. If you need more help just ask :) tip: one base will only join with a different one. One won’t join to multiple (from what I know as of now)

Powdered iron is magnetic, but powdered sulfur is not. What occurs when they form a mixture in a beaker at room temperature ?
Aloiza [94]
For the constituents of a mixture, they retain their individual properties meaning iron remains magnetic and sulfur remains a non metal and non metallic.

Which statement is true about OH-?
kobusy [5.1K]

The correct statement about OH ions :  

It’s a polyatomic anion because it has more than one atom and a negative charge.

<h3>Further explanation </h3>

Ions are atoms that have a charge

Ions are formed because capturing or releasing electrons.

Ions can be differentiated based on the number of constituent elements they become

  • 1. monatomic ion, if it comes from one element, such as K⁺, Mg²⁺, Cl⁻
  • 2. polyatomic ion, if it comes from two or more elements such as PO₄³⁻, SO₄²⁻, ClO₃⁻

Based on the charge, ions can be divided into:

  • 1. positive ion (cation)

happens if the atom releases electrons, for example

Al³⁺, ---> Al⇒ Al³⁺ + 3e⁻

Pb²⁺, ----> Pb⇒ Pb²⁺ + 2e-

  • 2. negative ion (anion)

happens if the atom captures electrons, like

S²⁻, S + 2e⁻⇒ S²⁻

F⁻, F + e⁻⇒ F⁻

OH- ions are usually associated with bases

According to Arrhenius, defines that

A base is a compound that can release OH- ions

Example:

NaOH (aq) -> Na + (aq) + OH- (aq)

The amount of OH- ions that can be produced by base compounds is called base valence.

OH ions are formed from the elements O and H so that they are polyatomic ions

OH ions are negatively charged so they are called anions
