Question #7af06 - Socratic R - the universal gas constant, usually given as 0 0821 atm⋅L mol⋅K T - the absolute temperature of the gas Now, every time you're dealing with problems that involve the ideal gas equation, your focus should be on making sure that the units given to you match those used in the expression of the universal gas constant, R
Question #ade0c - Socratic As you know, changes in temperature are identical for temperature expressed in degrees Celsius and for Kelvin, you can say that the calorimeter has a heat capacity of "1 kJ"^@"C"^ (-1) Now, heat capacity tells you how much heat must be added or removed from a system in order to cause a 1^@"C" change in its temperature
Question #f37a1 - Socratic Vertex is at (3 5, -0 5) , axis of symmetry is x=3 5, y-intercept is at (0,24), x-intercepts are at (3,0) and (4,0) F (x)=2x^2-14x+24 = 2 (x^2-7x+ (7 2)^2)-49 2+24 or F (x)= 2 (x-7 2)^2-1 2 Comparing with standard equation F (x)=a (x-h)^2 +f , (h,f) being vertex , we get vertex as h=7 2 , f= -1 2 or (3 5, -0 5) Axis of symmetry is x=3 5 y-intercept can be obtained by putting x=0 in the
What is 29 degrees celsius in fahrenheit? - Socratic The numbers to remember are 5, 9 and 32 Fahrenheit are the lager number when comparing like temperature for like So to convert Centigrade to Fahrenheit, you need to make the numbers bigger Thus you multiply by 9 5 To go from Fahrenheit to centigrade you are making the numbers smaller so you multiply by 5 9 All you need to remember now is that freezing point for each is different Centigrade
Question #18acf - Socratic 0 341dm^3 1 mole of any ideal gas occupies a volume of 22 7dm^3 at STP We will use this fact to work out the volume of oxygen produced From the equation, we are given the mole ratio H_2O_2:O_2=2:1 But we have 0 03000 moles of peroxide H_2O_2:O_2=2:1 =0 03:0 015 mol (I'm cutting off the extra 0s to make it easier to read In reality, you should probably leave these in) Back to the fact given
Question #9415f - Socratic Now that we have the slope, we can choose a point and use the point-slope form of a linear equation, y −y1 = m(x − x1), to find the equation of the graph y = f (x)
Question #5e9e6 - Socratic "2 25 years" Your tool of choice here will be the equation color (blue) (|bar (ul (color (white) (a a)A_t = A_0 * 1 2^n color (white) (a a)|))) Here A_t - the amount undecayed after a period of time t A_0 - the initial mass of the radioactive isotope n - the number of half-lives that pass in a period of time t In your case, you know that it took 9 years for a sample of a given radioactive
