f(x)=(2x+1)^0.5 for x >-0.5. Find f(12) and f'(12)

f(12)=((212)+1)^0.5=25^0.5=5 (simply substitute 12 into the original function)To find f'(12) we need to first find the derivative of the function and then we can substitute 12 in like we did before.f'...

2HCl (aq)+CaCO3 (s)->H20(l)+CaCl2(aq)+CO2(g). If using 40cm^3 of 2.5mol.dm^-3 Hcl and 5.67g of CaCO3, determine the limiting reagent and how much CO2(g) could be theoretically produced by this reaction.

First, we have to convert the starting measurements for the HCl and CaCO3 content into moles so we can compare the ratios to the formula. 40cm^3=0.04dm^30.04dm^32.5mol.dm^-3=0.1 moles of HClmass/molar...
