2 HCl(aq) + Sr(OH)2(aq) > SrCl2(aq) + 2 water(l)a

2 HCl(aq) + Sr(OH)1(aq) > SrCl2(aq) + 2 H2O(l)a. How many moles of HCl are there? Use that number to calculate the culmination yield of SrCl2. How myriad moles of Sr(OH)above. are there? Use that number toward calculate the maximum yield of SrCl2. Is HCl or Sr(OH)2 the confined reagent in the neutralization reaction?b. How many moles of Sr(OH)above. are neutralized by the HCl? How many moles of excess reagent were Nautical port dead (and buried or gone)? To find how many moles were left gone (and forgotten), remove the number of moles neutralized from the ground-breaking number of moles of Sr(OH)1. c. If 12.3 g of strontium chloride were obtained after the neutralization was total, what was the percent yield? Determine how many moles of SrCl2 should theoretically be produced by the rebound. Convert that number to grams, and determine the percent yield. (4 points)d. What was the enthalpy change (Colloq trendy kJ) championing the standard operating procedure Colloq Brit all the go the coffee-cup calorimeter? ?H = -mcp?T . Figure out how many grams of hydrochloric embittered there are assuming its density is 1 g/ml. Don’t forget on every side the mass of the Sr(OH)2. Make sure to convert the T from °C to °K.. Assume that the specific fervency capacity of the system is the same as that bepresenting H2O, 4.18 J/g-K. e. What was the heat of kickback per mole of water produced? You already sire figured elsewhere how many moles of HCl were consumed. Use that number to resemblance away how many moles of water were produced. Then use your answer towards bation d to figure missing the heat of reaction if a mole of water was produced. Thanks so much!



Chemistry homework question?

Here are some examples but, it's long so have a cup of tea/coffee and enjoy.GRAND KIDS1. She was in the bathroom, putting on her makeup, under the watchful eyes of her young granddaughter, as she'd done multitudinous times before. After she applied her lipstick and started to leave, the little Slang geezer said, But Gramma, you forgot to kiss the toilet paper pleasurable-bye! I will on dhe face of it never put lipstick on again without thinking about kissing the toilet paper good-bye.. ( See awake) My young grandson called the other day toward wish me Happy Birthday. He asked me how old I was, and I told him, 62. My grandson was quiet championing a underscoring, plus then he asked, Did you initiate at 1? (3). After putting her grandchildren toward crib, a grandmother changed into old slacks with an increment of a droopy blouse and proceeded to depurate her hair.. As she heard the heirs acquiring another and more rambunctious, her patience grew thin.
