A bus slows down uniformly from 60.9 km/h to 0 km/h in 21.3 s. How far does it travel before stopping?Answer in units of m.
A fishing boat accidentally spills 15.0 barrels of diesel oil into the ocean. Each barrel contains 42 gallons. If the oil film on the ocean is 2.5 x 10^2 nm thick, how many square meters will the oil slick cover? Assume that the oil slick forms a cube rather than a cylinder.
The muscle tone of the along the colon contracts it lengthwise, causing its walls to bulge and form pouches called
When 0.517 g of compound X is burned completely in a bomb calorimeter containing 3000 g of water, a temperature rise of 0.229oC is observed. What is ΔU rxn for the combustion of compound X? The hardware component of the calorimeter has a head capacity of 3.47kJ/oC. The specific heat of water is 4.184 J/g-oC, […]
Two long, parallel wires are separated by a distance of 3.40 . The force per unit length that each wire exerts on the other is 3.20×10−5 , and the wires repel each other. The current in one wire is 0.660 .
Thetotal number of d-electrons in Fe2+ (Z = 26) is not equal to that of
A compound is 40.0% rm C, 6.70% rm H, and 53.3% rm O by mass. Assume that we have a 100.-rm g sample of this compound.What are the subscripts in the empirical formula of this compound?Enter the subscripts for rm C, rm H, and rm O, respectively, separated by commas (e.g., 5,6,7).
A titration to determine the Ksp of MgCO3 is done by adding 0.030M MgCl2 to 50.0mL of 0.010M Na2CO3. The titration requires 10.50mL to observe the first visible precipitate. Calculate the solubility product of MgCO3 from this data. Show Work.
The probability of finding an electron at a point in an atom is referred to as the probability density (). The spatial distribution of these densities can be derived from the radial wave function and angular wave function , then solving the Schrdinger equation for a specific set of quantum numbers.Which of the following statements […]
If you assumed the same height for each student (regardless of their actual height) when you estimated their distances, your measured distances would show [more/less] scatter around your best t line? 4. Suppose you could guess a dierent height for each of the 5 students (say, by assuming that women are shorter than men, or […]
