Could you Balance NH4NO3 - N2 O2 H2O?
2NH4NO3->2N2+O2+4H2O
NaH2 plus O2 equals Na plus H2o?
2NaH2 + O2 yields 2Na + 2H2O
How do you calculate the amount of CuS and Cu2S in an ore sample given a known sample amount and amount of impurity?
Copper metal can be prepared by roasting copper ore, which can contain cuprite (Cu2S) and Copper (II) sulfide. Cu2S + O2 -> 2Cu + So2 CuS + O2 -> Cu + SO2 Suppose an ore sample contains 11.0% impurity in addition to a mixture of CuS and Cu2S. Heating 100.0 g of the mixture produces 75.4 g of copper metal with a purity of 89.5%. What is the weight percent of CuS in the ore? The weight percent of Cu2S? Clicked enter too fast, sorry.
What is the altitude of an isosceles triangle whose base is 10 and whose congruent sides are 9?
Simple application of Pythagoras Congruent side becomes the hypotenuse of a right-angled triangle with a known side of 5 (half the base). Doing the math we get the following: H2 = O2 + A2 92 = O2 + 52 rearranging we get O2 = 92 - 52 O2 = 81 - 25 O2 = 56 therefore O = √56 which is approximately 7.48 to decimal places
What is the shape of O2?
A molecule of two atoms is always linear.
