Most likely d because water is being used for energy, therefore releasing water vapo. Also by process of elimination, that´s the one that makes sense lol.
Non-Metals:
Hydrogen
Oxygen
Carbon
Nitrogen
Fluorine
Phosphorus
Sulfur
Chlorine
Selenium
Bromine
Iodine
The answer will be (4) HI because the greater the difference of the bonds in electronegativity, the more polar a bond is.
Answer:
Reactants: K = 2, S = 1, Co = 1, Cl = 2; Products: K = 2, S = 1, Co = 1, Cl = 2
Explanation:
The reaction is a double replacement reaction so the anions (Cl⁻ and S²⁻) switch places.
<u>1</u> K₂S + <u>1</u> CoCl₂ ⇒ <u>2</u> KCl + <u>1 </u>CoS (balanced chemical equation)
On the reactants and products side, K = 2, S = 1, Co = 1, and Cl = 2.
Hope that helps.
When red litmus turns blue, means the solution is basic, so it has more OH⁻ (hydroxide) ions.
