C I’m pretty sure. I can explain just lmk
Acids are hydrogen-containing compound that ionize to yield hydrogen ions (H⁺) in an aqueous solution
-bases are compound that ionize to yield hydroxide ions (OH⁻) in an aqueous solution
Answer: 6.18 g/L
Explanation:
To calculate the density of gas, we use the equation given by ideal gas equation:
Number of moles (n) can be written as:
where, m = given mass
M = molar mass
where,
which is known as density of the gas
The relation becomes:
.....(1)
We are given:
M = molar mass of = 146.06 g/mol
R = Gas constant =
T = temperature of the gas =
P = pressure of the gas = 1 atm
Putting values in equation 1, we get:
Thus density of sulfur hexafluoride gas at exactly 15°C and exactly 1atm is 6.18g/L
Answer:
La radiación UV-B es parcialmente absorbida por el ozono y llega a la superficie de la tierra, produciendo daño en la piel. Ello se ve agravado por el agujero de ozono que se produce en los polos del planeta.
Explanation:
The molarity of the ammonia solution is 1.38 M
<h3>Definition of molarity</h3>
Molarity is defined as the mole of solute per unit litre of the solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>Determination of the mole of NH₃</h3>
•Mass of NH₃ = 23.5 g
•Molar mass of NH₃ = 14 + (3×1) = 17 g/mol
•Mole of NH₃ =?
Mole = mass / molar mass
Mole of NH₃ = 23.5 / 17
Mole of NH₃ = 1.38 mole
<h3>Determination of the molarity </h3>
•Mole of NH₃ = 1.38 mole
•Volume = 1 L
•Molarity of NH₃ =?
Molarity = mole / Volume
Molarity of NH₃ = 1.38 / 1
Molarity of NH₃ = 1.38 M
