Which pair of ions can form an ionic bond with each other and why? cumc006-1.jpg and agmc006-2.jpg; they are both metal ions. smc006-3.jpg and omc006-4.jpg; they have like charges. brmc006-5.jpg and atmc006-6.jpg; they are both halogen ions. limc006-7.jpg and brmc006-8.jpg; they have unlike charges.

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

When the chemicals iron sulfide (fes) and hydrochloric acid (hcl) are combined, bubbles appear from the mixture. 1. does the appearance of bubbles indicate a physical or chemical change? 2. why do the bubbles indicate this change? 3. what property is this?

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
