A more accurate representation of the heating curve obtained with the equipment currently used for the experiment. Use the plot and the data to calculate the specific heat capacity of a 30 g graphite rod.
Initial temperature of rod = 100 °C; mass of H2O in calorimeter =130 g; cH2O = 4.184 °C g . (Assume the calorimeter has negligible heat capacity).
A. 0.20 J °C-1 g-1
B. 0.71 J °C-1 g-1
C. 0.66 J °C-1 g-1
D. 0.77 J °C-1 g-1
a calculator to calculate the average and standard deviation for x1 through x12. i know how to find the average but i dont understand how to findthe standard deviation.
The product of the reaction between chloro(cyclopentyl)magnesium and pentan-2-one was treated with H2O.
A (identical to the starting ester) and E. Propose a neutral structure for each compound that is consistent with the data. Note that the absolute stereochemical configurations of chiral substances cannot be determined from the data. Arbitrarily dr..
HCl by mass and has a density of 1.20g/ml .How much concentrated solution would you take to prepare 2.75L of 0.430 M HCl by mixing with water?
When 5.00g of copper reacts with oxygen, the copper oxide product has a mass of 5.62g. What is the empirical formula of this copper oxide? MM Cu= 63.5, O= 16.0
Buffer solution Problem to determine pH, Determine the pH after the addition of 10.0ml of 0.1M NaOH to 100.00ml of this buffer. An aqueous solution of 100.0ml 0.100M NaCl is titrated with 0.100M AgNO3 (AgCl Ksp= 1.0x10^-10) pAg=-log[Ag+]
The water temperature before the reaction was 34.5°C, and after the reaction it had risen to 52.0°C. How many moles of water were formed?
Given an unknown monoprotic(one hydrogen) acid. Make a 100 mL solution with 20% by volume. (mix 20 mL acid with 80 mL water) and titrate with NaOH. You must find the concentration of it the weak acid.
For each species listed, indicate the hybrid orbital set (sp2, sp3d, etc) employed by the central atom
For the competitive reaction between an equimolar propanal/acetone mixture and cyanide, show that PA/PK = kA/kk
Calculate the Z for the fourth ionization of Ti when it requires 425.6 kJ of energy to ionize 0.185 moles of Ti^3+ to Ti^4+ ( The electron being removed is in the outermost valence orbital of Ti^3+ ground state, therefore n = 3)
If 1020C of charge is passed through a solution of AgNO3(aq), calculate the number of moles of silver deposited.
