Partial pressure of gas A is 1.31 atm and that of gas B is 0.44 atm.
The partial pressure of a gas in a mixture can be calculated as
Pi = Xi x P
Where Pi is the partial pressure; Xi is mole fraction and P is the total pressure of the mixture.
Therefore we have Pa = Xa x P and Pb = Xb x P
Let us find Xa and Xb
Χa = mol a/ total moles = 2.50/(2.50+0.85) = 2.50/3.35 = 0.746
Xb = mol b/total moles = 0.85/(2.50+0.85) = 0.85/3.35 = 0.254
Total pressure P is given as 1.75 atm
Pa = Xa x P = 0.746 x 1.75 = 1.31atm
Partial pressure of gas A is 1.31 atm
Pb = Xb x P = 0.254 x 1.75 = 0.44atm
Partial pressure of gas B is 0.44 atm.

Answer: 9.09 %
Explanation:
To calculate the percentage concentration by volume, we use the formula:
Volume of ethanol (solute) = 30 ml
Volume of water (solvent) = 300 ml
Volume of solution= volume of solute + volume of solution = 30+ 300 = 330 ml
Putting values in above equation, we get:
Hence, the volume percent of solution will be 9.09 %.

Answer: The faster stuff or an object moves, the more energy it has. ... Energy can be transformed from one way to another. Kinetic energy can be told apart from the various forms of potential energy. A demonstration is: toaster transforms electrical energy into thermal energy.
Explanation: An energy transformation is the change of energy from way to another. Energy transformations occur everywhere every second. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, and chemical. Because the law of conservation of energy states that energy is always conserved in the world and simply changes from one form to another, many energy transformations are taking place all the time
