need help with both parts and with steps please. thank you
need help please. this is 1 question since its the same chaper (11) and on the program it shows as part A-C but I only need help with part A and B.
PART A: How much heat (in kJ) is evolved in converting \( 2.00 \) mol of steam at \( 139 . \mathrm{C} \) to ice at \( -46 \) . C? The heat capacity of steam is \( 2.01 \mathrm{~J} /(\mathrm{g} \cdot \mathrm{C}) \), and that one of ice is \( 2.09 \mathrm{~J} /(\mathrm{g} \cdot \mathrm{C}) \). Express your answer in kilojoules to three significant figures. \[ \left|q_{\text {total }}\right|= \] PART B: Solve for \( x \), where \( M \) is molar and \( s \) is seconds. \[ x=\left(4.2 \times 10^{3} M^{-2} \mathrm{~s}^{-1}\right)(0.24 M)^{3} \] Enter the answer. Include units. Use the exponent key above the answer box to indicate any exponent on your units.
