We’d have to be very careful because if we had our skeletons on the outside it’d be very easy to injure ourselves
Pure substances are further broken down into elements and compounds. Mixture are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
Answer;
The total pressure is 1.107 atm.
Explanation;
The total pressure is the sum of the pressures of the three gases in the flask
Pressure (total) = 0.215 atm + 0.066 atm + 0.826 atm = 1.107 atm
= 1.107 atm.
Answer:
54.075KJ
Explanation:
Since methane is the limiting reactant.
From the reaction equation,
16 g of methane absorbs 206 KJ of energy
4.20 g of methane will absorb 4.20 × 206/16 = 54.075KJ of energy was absorbed.
From the equation, the value of the enthalpy of reaction is positive, this means that energy is absorbed in the reaction of methane and water. Hence the answer.
