If the concentration for Ca+ is 0.003 and the concentration for C2O4 is 0.017 What is the KSP for CaC4O2? Ksp=[Ca][C2O4] ?
How would I calculate this? I'm very confused I got 8.7 x 10 ^-5 which i doubt is correct.

Which element is least likely to undergo a chemical reaction

What amount of heat is exchanged when 106.2 grams of substance y goes from a liquid at 35 degrees celsius to a solid at the same temperature? melting point of substance y = 35 degrees c; δhvaporization = 3.67 j/mol; δhfusion = 3.30 j/mol. mwsubstance y = 28.22 g/mol. −12.4 j −3.51 x 102 j 1.24 x 101 j 351 j

In what way do investigations build scientific knowledge? the results of investigations lead to questions that cannot be tested. they reflect the opinions and social values of scientists, ensuring valid information. the results of investigations lead to new questions, which lead to new investigations. they are not influenced by the research of earlier scientists, so they are able to address gaps in understanding.i
