b. To what region of electromagnetic spectrum does this correspond?
Using the following data, calculate the pressure of 1.00mol of Ar(g) in a 40.0L container at 25 degrees Celcius using both the ideal gas equation and the real gas equation. Why are these two values so different? (aAr=136 ...
When .0430 mole of titanium is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 30.00degress Celsius to 91.60 degrees Celsius. In a separate experiment, the heat capacity of the calorime ...
Titanium reacts with hydrogen peroxide in 1.00 M sulfuric acid to form a colored complex. If a 2.00x10^-5 M solution absorbs 31.5% of the radiation at 415 nm, what would be: the absorbable, the transmittance, and the per ...
Question 1 Decide why the heat from a candle flame is barely tolerable when a person places his or her hand above the candle compared to when the hand is placed next to the candle. The highest temperature is at the tip o ...
Why is the freezing point of water set at 32ºF? Why does the Fahrenheit scale start at 0º?
A 200 g sample of water with a temperature of 32?C is added to 50 g water at 55?Cin an insulated container. What is the final temperature after thermal equilibrium is reached? The specific heat of water in the liquid sta ...
A cleaning solution is found to have a [OH-] = 3.2 x 10 -12 M. What is the [H 3 O + ] and is the solution acidic or basic?
Question 1 - State why the second part of each statement is incorrect and correct it. a) Ammonium phosphate is (NH 3 ) 4 PO 4 b) Ammonium hydroxide is ALOH 3 c) Cr(NO 3 ) 3 is chromic(ii) chloride d) ...
What mass of NaH 2 PO 4 must be added to 1.20 L of 0.20 M Na 2 HPO 4 to make a buffer solution whose pH=6.90? pK a2 (H 3 PO 4 )=7.21.
1. The stress induced in a column subjected to an eccentric load is given by the following equation; P/A = (S yc /[1+(ex/k 2 )sec((l/2k)(√(P/AE)))]) where P is the axial load (lb f ), A is the cross-sectional area of the ...
