Is the equation balanced? Why or why not?
Na3PO4 + 3 KOH --> 3 NaOH + K3PO4
O Yes because the law of conservation of energy is followed. There are equal amounts of energy in the reactants and
products.
No because the law of conservation of energy is not followed. There are different amounts of energy in the reactants
and products.
No because the law of conservation of matter is not followed. The mass of the reactants is greater than the mass of the
products.
o Yes because the law of conservation of matter is followed. There are equal numbers of atoms of all elements in the
reactants and products.

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes.which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature.sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent
