what is the molarity of a solution made when you dilute 35 grams of sodium carbonate to a volume of 3400 ml?
How many grams of liquid methanol (CH3OH) are needed to heat 425 mL of water from 18 oC to 43 oC by combustion with oxygen.
Given the unbalanced equation, Cr(NO3)3(aq) + LiOH(aq) LiNO3(aq) + Cr(OH)3(s), how many grams of Cr(OH)3 are produced from 0.084 g of Cr(NO3)3?
What mass of natural gas (CH4) must burn to emit 470. kJ of heat? CH4(g) + 2 O2(g) CO2(g) + 2 H2O(g).
How much heat (in ) is required to warm 12.0 of ice, initially at -12.0, to steam at 114.0? The heat capacity of ice is 2.09 and that of steam is 2.01 .
Based on standard reduction potentials, would you expect copper metal to oxidize under standard conditions in the presence of oxygen and hydrogen ions
The molar absorptivity for the complex formed between bismuth (III) and thiourea is 9.32 x 103 L mol-1 cm-1 at 470 nm. Calculate the range pf permissible concentrations for this complex if the percent transmittance is to be greater than 15.0 % and..
Determine ΔHreaction° for: 4H2O (l) + 2 NH3 (g) → 2NO2 (g) + 7H2 (g) using the following two equations: (1) N2 (g) + 3H2 (g) → 2 NH3 (g) ΔH1° = -184 kJ (2) 4NO2 (g) + 8H2 (g) → 2 N2 (g) + 8 H2O (l) ΔH2° = -196 kJ
How many kilograms of CO2 are produced from the complete combustion of 1.00L of gasoline assume that the gasoline has the formula C8H18.
In one city, a balloon with a volume of 6.0 L is filled with air at 101 kPa pressure. The balloon in then taken to a second city at a much higher altitude
if you used 8900 kilojoules you expend in energy in one day to heat 49000g of water at 19 C what would be the rise in temperature.
What volume of .250 M NaOH is required to neutralize a 10mL sample of .750 M HCl.
Calculate concentrations of OH- and the pH of each basic solution. Since NaOH donates on OH- ion for each NaOH molecule, the OH- concentration is equivalent to the NaOH molarity. The pOH is calculated as -log[OH-] and the pH is calculated as 14-pO..
