<p>^whats the covalent question SHAHEIRUDDIN?</p>
<p>jamesford, that would be density</p>
<p>ya 10 char</p>
<p>Propane had 10 covalent bonds: 2 C’s had 3 bonds, 1 C had 2 bonds, and each C was bonded to each other. 2(3)+2+2=10</p>
<p>101 was TF I’m pretty sure. I know the second part was false because increasing pressure does not increase molecular speed, only temperature can do that.</p>
<p>Rb reacts most with water. All alkali metals react violently with water: for example, potassium bubbles and generates so much heat that the hydrogen gas released from the reaction catches on fire.</p>
<p>For the one about state functions of temperatures, I’m pretty sure that the answer was pressure. Although one would assume that increasing the temperature increases pressure, it only increases volume, which could lead to an increase in pressure if the volume is fixed. So the two variables are independent of one another. Density IS a state function of temperature, since the temperature affects the volume of a gas and thus its density.</p>
<p>But density = m/v and pv/t = pv/t, so temperature has a direct relationship to volume. So if volume is affected, then so is density.</p>
<p>^do you remember what the covalent question you keep talking about asked? The only question I recall is the one about propane having 10 covalent bonds</p>
<p>confirmed answer is denisty</p>
<p>ut2244…thats what i thought at first but keep in mind that pressure also changes directly with temperature to counteract any increase in temp</p>
<p>If it asked for the best answer then it would be density. P being proportional to T is a major gas law.</p>
<p>pressure and temperature are directly related according to the i deal gas law. The answer just has to be density.</p>
<p>we need rockermcr lol he would know the answer</p>
<p>shaheirruddin, i dont mean to be a prick but Ive asked you 3 times…wat is the covalent bond question you are talking about?</p>
<p>the one with propane i got it wrong</p>
<p>I think he mistakenly thought that propane having 3 carbons would mean only 3 covalent bonds.</p>
<p>oh ok i thought you were talking about a diff one</p>
<p>Density is dependent on temperature for gases! The mass remains constant, so the volume is dependent on the temperature if one wants to find the temperature. It was not specified that a volume of a gas is fixed like if it were in a container. Since it is not fixed, the gas will expand based on its temperature, and its pressure will not increase since the volume increases to relieve the stress of a higher pressure. Pressure is NOT a state function of gas, and that is the answer.</p>
<p>Actually, the question specifically states if volume is held constant…or so I think</p>
<p>Oh, and Pressure is a funtion of T. It is directly proportional if you remember Gay-Lussacs law</p>
<p>pressure is directly related to temperature…</p>
<p>it was denisty</p>
<p>anbody remember the coiffecient of h2o with the H2s compund was it 1</p>
