A 170.0 g sample of metal at 79.00*C is added to 170.0 g of H2O(l) at 14.00*C in an insulated container. The temperature rises to 16.19*C. Neglecting the heat capacity of the container, what is the specific heat of the metal? The specific heat of H2O(l) is 4.18J/(g x *C). Please show the formula used and detailed work on how to solve this.
Draw the following containing 3 carbon atoms- aldehyde,alcohol,amine,ether,carboxylic acid and ketone
What is the system that is buffered, what is the pH of the system and what compounds are responsible for the buffered system?
after the correct formula for a reactant in an equation has been written , what can be changed to balance the equation?
Imagine that you have a 5.50 gas tank and a 4.00 gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
Dinitrogen pentoxide, N2O5, decomposes in the gas phase to form nitrogen dioxide, NO2, and oxygen gas, O2. The reaction is first order in dinitrogen pentoxide and has a half-life of 2.81 hours at 25 C.
The solution to physical chemistry, A laser used to read CDs emits red light of wavelength 700 nm. How many photons does the laser emit per second
What is the pH of a solution which results from mixing 150 mL of 0.50M acetic acid and 150 mL of 0.50M sodium hydroxide at 25oC?
The cobalt(II) ion, Co^(2+), is especially responsive to magnetic fields, more so that Co^(1+) and Co^(3+). Why
Calculate the energy of a photon emitted when an electron in a hydrogen atom undergoes a transition from n = 6 to n = 1.
Air is 21 mole percent oxygen, that is, 0.21 atm oxygen at 1 atm. Suppose the pH of the water is 4.54 and that the concentration of iron(II) in the water is 5.16x 10-5 M, what is the potential of the corrosion reaction under the above conditions a..
