You react 100.0 ml of a 1.01 M HBr(aq) solution with 99.1 mlof a 1.05 M KOH(aq) solution. The density of each solution is 1.04g/ml. The heat capacity of the calorimeter is 7.0 J/C. You observea ΔT of 6.3 C. Assume a 4.18 ...
The molecular weight of an unknown gas was measured by an effusion experiment. It was found that it took 64 seconds for the gas to effuse, whereas nitrogen required 48 seconds. The molecular mass of the gas is ?
What is the minimum amount of 6.0 M H 2 SO 4 necessary to produce 25.0g of H 2 (g) according to the reaction between aluminum and sulfuric acid? 2 Al(s) + 3 H 2 SO 4 (aq) --------> Al 2 (SO 4 ) 3 (aq) + 3 H 2 (g)
a) Glucose is a carbonate that your body can burn for fuel. It is 40 percent C and 6.71 percent H by mass. The rest is O. What is the empirical formula of glucose b) The molar mass of glucose os 180.0 g/mol. what is the ...
Consider the following reaction. A (g) + B (g) → C (g) + D (g) *In one experiment the concentration of A (g) was monitored in the presence of a large excess of B (g) ( [B] o = 0.750 M ) . Time (s) [A] (mol/L) 0.00 6.00 ...
A sample of a substance (containing only C, H, and N) is burned in oxygen. 8.696 g of CO 2 , 2.225 g of H 2 O and 4.446 g of NO are the sole products of combustion. What is the empirical formula of the compou ...
Calculate the dissociation constant of NH4OH(aq) if the degree of dissociation of 0.006 mol/kg solution is 0.053 and the activity coefficients of all species equal 1.
What will happen if I decide to test the solubility of sodium chloride in ethanol which is less polar than water.
Q1. Sodium metal is very active with water. Therefore, determining the value of a block of sodium will be impossible by water displacement. On the other hand, the density of sodium metal can be found in the chemistry han ...
If liquid is at or above it's flash point, the flame spread rate is fast, and the entire pool is engulfed within seconds. In such a case, the liquid is already evaporating sufficiently to reach the lower flammability lim ...
