In a reaction, one molecule of ammonia (NH3) reacts with one molecule of hydrochloric acid (HCI) to produce one molecule of ammonium chloride (NH4CI). Which statement is true about the reaction?
The reaction satisfies the Law of Conservation of Matter because the product is the combination of the two reactants.
The reaction does not satisfy the Law of Conservation of Matter because the two different reactants produced only one type of product.
The reaction satisfies the Law of Conservation of Matter because the number of atoms of each type before and after the reaction is the same.
The reaction does not satisfy the Law of Conservation of Matter because the arrangement of atoms in the reactants and the product is different.
no

Compare these two waves : a. the blue wave has a higher pitch, but the orange wave is louder. b. the blue and orange waves have the same volume, but the blue wave has a higher pitch. c. the blue and orange waves have the same pitch, but the blue wave is louder. d. the orange wave has a higher pitch, but the blue wave is louder.

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
