vinegar contains 5.0 g of acetic acid, CH3COOH,in 100.0 mL of solution. Calculate the molarity of acetic acid vinegar?
When you heated the hydrated compound this process starts slowly at first find out the reason behind this and compute k for this acid if A 0.020 M solution of weak acid HA is 0.60% ionized.
The resulting solution freezes at 26.5 oC. If Kf for the solvent is 1.74 o C/m then determine the molar mass of the nonelectrolyte compound?
What are the atomic orbitals used in the double part of the double bond If the C-C axis of the given molecule is the y axis, and the x axis is up and down in the plane of the paper,?
Solar furnaces are designed to focus sunlight (say, with a parabolic mirror ) onto a relatively small area. given that the surface temperature of the sun is about 600K.
A canister is filled with 320 of ice and 100. of liquid water, both at 0 . The canister is placed in an oven until all the has boiled off and the canister is empty.
What weight of chlorine gas will be needed to react completely with 85.8g of potassium iodide in a single replacement reaction.
From the heats of reaction as given 3O2(g) ---> 2O3(g) DH = +284.6 kJ, 2H2(g) + O2(g) ---> 2H2O(g) DH = -483.6 kJ
