Answer from: Quest

to improve her experimental investigation, dalila should add a row in which no fertilizer is used. by a having a contrasting row in which no fertilizer is used, she will have a control group that will her understand the effects of the fertilizer in the plant developments vs the development of the plant when no fertilizer is used.

Answer from: Quest

balanced chemical equations follow the law of conservation of mass and charges. the masses and charges on either sides of the equation should be balanced.in conservation of mass, the number of atoms of each element on left side should be equal to the number of atoms of each element on the right side of the equation.1)k₂so₄ + 2ca(no₃)₂ --> 2kno₃ + 2caso₄number of ions left side right side k⁺ 2 2so₄²⁻ 1 2ca²⁺ 2 2no₃⁻ 4 2in this equation the masses of so₄²⁻ and no₃ are not balanced. therefore this equation violates the law of conservation of mass2)ti + 2 cl₂ > ticl₄ left side right side ti 1 1cl 4 4this equation follows the law of conservation of mass3)2c₂h₂ + 5o₂ > 4co₂ + 2h₂o left side right side c 4 4h 4 4o 10 10this equation follows the law of conservation of mass4)baso₄ + 2naoh --> ba(oh)₂ + na₂so₄ left side right side ba 1 1so₄²⁻ 1 1na 2 2 oh⁻ 2 2this equation follows the law of conservation of massanswer is 1st equation

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
