I can not determine the answer for this problem...can someone please help me? Determine the number if moles of MgO that form from the reaction of 4.4 moles of O2 in the following unbalanced reaction: Mg + O2 ----> MgO The
Will someone help me by letting me know if I did these correct, or if there the correct answers? Thanks! 2 (10). If two moles of hydrogen gas (H2) react in the following equation, how many moles of H2O will be formed? 2H2 + O2
Did I do these right? Can someone let me know if I did them correctly? I had someone help me with the problems but know I want to make sure their the right answers? 1. Methane burns in oxygen according to the following equation:
Initially, there are 33 moles of A and 0 moles of B. How many moles of A and B will be present after the system reaches equilibrium? a) 33 moles A; 0 moles B b) 0 moles A; 33 moles B c) 3 moles A; 30 moles B d) equal amounts of A
A sample of 690. moles of O2 reacted according to the balanced equation, 4Al+3O2=2Al2O3 after reaction, 163 moles of O2 remained. calculate the moles of Al2O3 formed. Ive tried this problem many times and i keep getting it wrong.
2) For a theoretical yield of 19 g and actual yield of 11 g, calculate the percent yield for a chemical reaction. Answer in units of %. 11 g / 19 g times 100 = 57.89% in your 2 sigfig problem, you might be expected to round off to
