WebVerified answer. physics. You are pulling on a rope to move two boxes, box 1 and box 2, that are connected by a spring. The rope is connected to box 1 , which is on a surface with a coefficient of friction \mu μ. The spring connects it to box 2 , which is moving on rollers, so you can ignore friction. If the boxes move with a constant velocity ... Web2 apr. 2024 · Polyatomic ions. Polyatomic ions are molecular ions composed of two or more atoms bonded by covalent bonds and acting as a single unit, but unlike molecules, they have a net charge on them. The examples include cations like ammonium ion ( NH + 4 ), and hydronium ion ( H 3O + ); and anions like hydroxide ion ( OH − ), and cyanide ion ( … Web28 nov. 2016 · 4Fe(s)+3O_2(g)rarr2Fe_2O_3 Clearly, there are 6 oxygen atoms on the left hand side of the equation; and, equally clearly, there are 6 oxygen atoms on the right hand side of the equation, as indeed there must be in a stoichiometrically balanced equation.
