The given statement is shown below,
Balance the equation,
Balance the equation, when balancing the equation, we should not alter the subscripts and we can change coefficients. There are two fluorine atoms in the left side and one fluorine atoms in the right side. Therefore, two molecule of sodium fluoride are added to right side of reaction. Now, the balanced equation is given below.
There are two chlorine atoms in the left side and one chlorine atoms in the right side. Therefore, two molecule of sodium chloride are added to right side of reaction. Now, the balanced equation is given below.
There are two sodium atoms in the left side and four sodium atoms in the right side. Therefore, two molecule of sodium oxalate are added to left side of reaction. Now, the balanced equation is given below.

- You take 1.00 g of an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen), burn it in air, and collect 2.20 g CO2 and 0.400 g H2O. You know that the molar mass of aspirin is between 170 and 190 g/mol. Reacting 1 mole of salicylic acid with I mole of acetic anhydride (C4H6O3) gives you 1 mole of aspirin and 1 mole of acetic acid (C2H4O2). Use this information to determine the molecular formula of salicylic acid.arrow_forwardThe carbon dioxide exhaled in the breath of astronauts is often removed from the spacecraft by reaction with lithium hydroxide 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) Estimate the grams of lithium hydroxide required per astronaut per day.
