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
Answer:
Br - has the largest radius
Explanation:
These ions each have achieved the nearest noble gas configuration. Br - has a like electron configuration to that of Krypton, S2- has a like electron configuration to that of Argon, B3+ to Helium, Mg2+ to Neon, and Li+ to Helium.
_______________________________________________________
Traveling down a group, the radius tends to increase as atom gains another shell. Here we are comparing elements of like electron configuration to the noble gases Helium, Neon, Argon, Krypton. Krypton, being the last element present in the group out of the 4, has the greatest radius as it has the most shells. Thus, Br - has the largest radius.

Answer:
Explanation:
Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Neutralization reaction is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule.
Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
Example:
Double displacement reaction is one in which exchange of ions take place. Example:
The proton is 1
Electron is 1/1840
The neutron is 1
