Chemistry
1 answer:
Solnce55 [7]3 years ago
7 0

Ca=40.07841 ,Nitrogen=14.006722 ,Oxygen15.99943
molar mass= (1xMW of Ca)+(2xMWof N)+(6x MW of oxygen)
Molar mass (molecular weight) of Ca(NO3)2 is 164.0884 g/mol

Suppose you were given a substance and asked to determine weather or not it was a plasma. Write the characteristics you would lo
Sphinxa [80]

Electrical conductivity, electromagnetism, and temperature are the features that one would look for in order to determine plasma. Plasma refers to a hot ionized gas possessing high electrical conductivity. It is electrically neutral with negative and positive particles. It can be considered the most abundant form of matter in the universe.  

The features of plasma are substantially distinct from those of the usual neutral gases so that plasmas are regarded as a different fourth state of matter.

In the following reaction, how many grams of nitroglycerin C3H5(NO3)3 will decompose to give 25 grams of CO2?
gogolik [260]

4C₃H₅(NO₃)₃_{(l)} ------> 12CO₂_{(g)} + 6N₂_{(g)} +  10H₂O_{(g)}  +  O₂_{(g)}

mol of CO₂  =  \frac{mass}{molar mass}

                    =  \frac{25g}{44.01 g/mol}

mol ratio of  CO₂ :  C₃H₅(NO₃)₃

                    12    :     4

∴  if  mole of CO₂  =  0.568 mol

then   "       "   C₃H₅(NO₃)₃  =  \frac{0.568 mol}{12}  *  4

                                           = 0.189 mol


∴ mass of nitroglycerin  =  mole  *  Mr

                                       =  0.189 mol  *  227.0995 g / mol

                                       =  43.00 g
