Southern sea otters are keystone species that are important to the _ ecosystems in which they live​

The answer to your question would be  h+ + cn– + li+ + oh– mc001-4.jpg li+ + cn– + h2o. the total ionic equation for the following reaction is  h+ + cn– + li+ + oh– mc001-4.jpg li+ + cn– + h2o.

Heat capacity = mcδtheat capacity = 2.676×10^3 j ..the heat capacity given is for 7.00 g of kcn,potassium cyanide which is equal to 0. mole of mole = mass  ÷ mr of kcn is 7  ÷ 65 =0.therefore: 0. of kcn liberates 2.676×10^3 j of heat1 mole   (2.676×10^3    ÷  0.107 )  × 1 =do the calculation to obtain 25009 j = 25kj

The rules are different for multiplication and addition, but the least precise value always restricts the answer. first do the multiplication (as per standard order of operations): 24.6681 × 2.38 ≈ 58.7 since 2.38 has the fewest significant figures, it is considered the lease precise value then do the addition: 58.7 + 332.58 ≈ 391.3 since 58.7 has fewest figures right of decimal it is considered least precise. so final answer: 391.3 with four significant figures.
