Question- Calculate the mass of barium chloride you need to make a 0.200m barium chloride solution with 100.0g of water. Please show the set up and full work of how to get the answer.
Please define why you think that's the right answer
While 5.0 g of an unknown substance is dissolved in 100.0 g of water, the freezing point of the solution reduces by 1.5 degrees Celsius. Explain what is the molar mass of the unknown substance if the compound doesn't dissociate to form ions in sol..
What are the possibilities of the experimental error. Why is the zero order correlation coefficient better than first order
When a substance melts, bonds between the particles within the solid are broken, allowing the particles to become mobile and fluid. Ionic bonds and covalent bonds between atoms are comparable in strength
consider the combustion of methane, CH4:CH4 + 2 O2 (g) -->CO2(g) + H2O suppose 1.5 mol of methane is allowed to react with 4 mol of oxygen what is the limiting reagent?
Determine the mass of lithium hydroxide produced when 0.38 g of lithium nitride reacts with water to make Ammonia (NH3) and Lithium hydroxide.
Explain is the maximum amount in moles of NH3 that can be produced by the reaction of 2.5 moles of N2 with 3 moles of H2 via the equaton below.
As a chemist for an agricultural products company, you have just developed a new herbicide,"Herbigon," that you think has the potential to kill weeds effectively
For a hypothetical gas-phase reaction that is second order in A and third order in B, by what factor does the rate change if pA is decreased by 4 times and pB is doubled
Three 5 L flasks, fixed with pressure gauges and small valves, each contain 4 g of gas at 273 K. Flask A contains H2, flask B contains He, and flask C contains CH4. Rank the flask contents in terms of the following properties.
When you heat up popcorn, it loses water explosively and it pops. suppose a kernel of corn, weighing 0.125 grams weighs only 0.106 grams after popping.
The equilibrium constant for H2(g)+I2(g)->2HI at 40 oC is 20. The vapor [pressure of solid iodine at 40 oC is 0.1 bar. 12.7 g of solid iodine is placed in a 10 L vessel. What is the minimum amount of hydrogen that must be placed in the bulb to rem..
For the reaction:2CH4(g) C2H2(g) + 3H2(g) 0.115 mole of CH4 was placed in a 1.00 L container. At equilibrium it was found that the [C2H2] = 0.035 M. What is the value of the equilibrium constant?
