Calculate the heat capacity of satan, i. e. Ni . if 30.0g of nickel at 100.0 c raises the temperature of 25.0g of water from 22.0 c to 30.8 c . assume no heat loss to the surroundings
what effect will that have on the delta T values when the initial value is measured with the thermometer and the latter is measured with the temperature probe? How will this affect the calculated change in heat of that substance?
Based on coulombic attractions, list the magnitude of attraction between ions from the least to highest. why? Nacl, Na2SO4, MgSO4
Both stopcocks are opened. The pressure throughout the system is 33.5 mmHg. How many moles of N2 are in the system? How many moles of CO2 are in the system?
Draw the structure of the geometric isomer of 2-pentene that has the lower melting point.
Use the collision theory to calculate the theoretical value of the second-order rate constant (in m3 mol-1 s-1) for the gas-phase reaction D2 + Br2 = 2 DBr at 450 K assuming that it is elementary bimolecular. The collision cross-section for this r..

Determine the change in Ssys for the process if the specific heat capacity for ethanol = 2.42 J/g K. express your answer in units of J/K
Write the reactions of cinnamic acid with sodium bicarbonate and sodium hydroxide. What is the gas that is evolved when cinnamic acid reacts with sodium bicarbonate
If 6.06 L of O2 gas is collected over water at 250C (vapor pressure = 23.8 torr) and a barometric pressure of 702 torr, what is the mass of H2O2 (MM = 34.02 g/mole) decomposed?
A sample of drinking water collected from a suburban Boston municipal water system in 2002 contained 0.45 pCi/L of radon. Assume that this level of radioactivity was due to the decay
a 340 g aluminum cup holds and is in thermal equilibrium with 750 g of water at 83degc. the combination of cup and
