The heat released from the calculation is 33.56 kJ.
<h3>Heat of vaporization</h3>
The heat of vaporization is the heat absorbed when a substance changes from liquid to vapor. It is equal to the heat released when the vapor is condensed.
The total heat released = Heat of condensation + Heat lost to the skin
= (13.3 g × 2260 J/g) + (13.3 g × 4.18 J/g/°C × ( 100 - 37)°C)
= 30058 + 3502
= 33.56 kJ
The heat released from the calculation is 33.56 kJ.

Cellular respiration releases stored energy and glucose molecules and converts it into a form of energy that can be used by cells
This
can be solved using Dalton's Law of Partial pressures. This law states that the
total pressure exerted by a gas mixture is equal to the sum of the partial
pressure of each gas in the mixture as if it exist alone in a container. In
order to solve, we need the partial pressures of the gases given. Calculations
are as follows:<span>
P = P1 + P2 + P3
<span>P = (0.08206 atm.L/mol.K)( 298.15
K)/1.50) x (0.158 mole + 0.09 mol + 0.044 mol) = <span>4.76
atm</span></span></span>
Answer:
12-crown-4
Explanation:
We must recall that any structural moiety in organic chemistry having the R-O-R unit is an ether. If the oxygen form a ring in which they are sandwiched in between carbon atoms, the compound is known as a crown ether. The name emanates from the close resemblance of the compound to an actual crown.
If we want to name the crown ether, we first count the number of carbon atoms present and the number of oxygen atoms present. The correct name is now, total number of carbon + oxygen atoms -crown- number of oxygen atoms, in this case; 12-crown-4, hence the answer.
