The reaction of soda ash (Na2CO3) with calcium sulfate in water is represented by the following chemical reaction: Na2CO3 + CaSO4 >>> CaCO3 + Na2SO4. Assuming that this reaction is complete and that there is 153 mg/l of CaSO4 initially present, what is the mass of soda ash that must be added to 1 liter of the water?
Cars were timed by police radar as they passed in both directions below a bridge. Their velocities (kilometres per hour, numbers of cars in parentheses) to the east and west were as follows
Suppose you have a sample of sodium weighing 11.62 g. How many atoms of sodium are present in the sample?
Why was cold deionized water added to the reaction mixture rather than hot water, and what is the purpose of acetic acid?
determine if a redox reaction would occur if you were to mix them in a single solution. For those pairs of substances that would not react, calculate the EOCELL of the unfavored reaction between the two substances.
