Answer:
The given statement is false.
Explanation:
Acid as are defined as those substance which gives hydrogen ions in their aqueous solutions.

Base as are defined as those substance which gives hydroxide ions in their aqueous solutions.

The given statement is false.The correct statement is :
Bases increase the concentration of hydroxide ions by donating hydroxide ions to water molecules.
Answer: 7 atm
Explanation:
According to Dalton's Law, the total pressure is the sum of all the individual gas pressures
Hence, Ptotal = P1 + P2 + P3
Since, Gas A = 2 atm
Gas B = 1 atm
Gas B = 4 atm
Ptotal = (2 + 1 + 4) atm
Ptotal= 7 atm
Thus, the total pressure of the gas mixture is 7 atmosphere.
Answer:
The law is given by the following equation: PV = nRT, where P = pressure, V = volume, n = number of moles, R is the universal gas constant, which equals 0.0821 L-atm / mole-K, and T is the temperature in Kelvin.
