Osmium is the most densest substance
Answer:
52
Explanation:
Alkanes are saturated hydrocarbons, that is, they are formed just by carbon and hydrogen atoms bonded through single covalent bonds. The general formula for alkanes is CnH2n+2.
If n = 25 (25 carbon atoms), 2n + 2 = 2 × 25 + 2 = 52. There are 52 hydrogen atoms in the structure and the alkane has the formula C₂₅H₅₂.
You can't draw on here but if you are looking for the molecular shape of CO2 it is linear. The central atom (C) is bonded to two atoms and has no lone pairs. It has a bond angle of 180 degrees and a hybridization of sp.
Answer:
E) pure water.
Explanation:
- AgCl is a sparingly soluble salt in water which is dissociates according to the reaction:
<em>AgCl ⇄ Ag⁺ + Cl⁻.</em>
- Adding NaCl, KCl, BaCl₂, and AgNO₃ will shift the equilibrium to the left according to Le Chatelier's principle that the presence of these salts will increase the concentration of Cl⁻ (NaCl, KCl, BaCl₂) or increase the concentration of Ag⁺ (AgNO₃), so the reaction is shifted towards the reactants side decreasing the solubility of AgCl.
<em>So, the greatest solubility of AgCl will be in pure water.</em>
Acid and base reactions example is: acid+base=salt+water
