Q = m c T Q = heat energy m = mass c= specific heat capacity T = change in temperature How much heat is required to raise the temperature of 67.0g of water from 25.7°C to 66.0°C? The specific heat of H2O is 4.184J/g°C) Please show your work

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.
