Answer:
76 mmHg
Explanation:
The partial pressure of a gas in an ideal gas mixture is the pressure that this gas would exercise if it was alone in the same temperature of the gas mixture.
For the Raoult's law, we can determinate the partial pressure of a gas(Pa) knowing the total pressure (P) and its molar fraction(Xa):
Pa = XaP, so for the oxygen :
Pa = 0.10x760
Pa = 76 mmHg
C to D
Explanation:
it rises faster between those two points
0.074Hz is the answer to that
Answer:
The process of making S'more by adding chocolate bar, gram-crackers, and marshmallows in layers is not a chemical reaction
Explanation:
In a chemical reaction, the substances involved in the reaction are known as the reactants and the substances produced have different physical and chemical properties than those of the reactants and they are known as the products.
The bonds that hold the atoms of the reactants are broken down and rearranged, creating entirely new substances as products. Therefore, energy must be added and/or evolved in any chemical reaction and all reactant atoms should be involved in the reaction.
The change in energy can be sensed as heat change such as increase or decrease in the temperature of the products
Since S'more does not involve any of the above changes that occur in a chemical reaction when the chocolate bar, gram-crackers, and marshmallows are put together, it is not a chemical change or a chemical reaction.
