A2.9-m-long, 490 g rope pulls a 3.8 kg block of ice across a horizontal, frictionless surface. the block accelerates at 2.19 m/s2. how much force pulls block forward on the ice?

A 2.9-m-long, 490 g rope pulls a 3.8 kg block of ice across a horizontal, frictionless surface. the block accelerates at 2.19 m/s2. how much force pulls block forward on the ice? Consider how you are posting a physics question i nchemistry yo

No table found. the question asks for covalent bond based on electronegativies

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
