In water, an element can dissolve that is least likely to be an ionic compound.
What substances are most likely to result in ionic compounds?Ionic compounds typically form when metal and nonmetal elements are combined. For instance, the nonmetal chlorine (Cl) and metal calcium (Ca) combine to form the ionic compound calcium chloride.
Noble Gases are colorless gases with a very low reactivity. The noble gases are referred to as inert because they don't easily combine with other substances to form compounds. The noble gas family consists of helium, neon, argon, krypton, xenon, and radon.
Compound formation involving noble gases is extremely rare. They are incomprehensible gases that don't interact with other substances in their environment.

brainly a mixture of two gases with a total pressure of 5.60 atm contains 0.40 atm of gas a. what is the partial pressure of gas b?
The partial pressure of gas B is 5.2 atm.
What do you understand by partial pressure?
When more than one gas is present in a container, each gas exerts pressure, which is known as partial pressure. Its partial pressure refers to the pressure of any gas inside the container.
Let there be n different gases in the mixture, each at a different pressure (P1, P2, etc.)
Then the total pressure will be:
[tex]P_{total}[/tex] = ∑[tex]P_{1}[/tex] + [tex]P_{2}[/tex] + [tex]P_{3}[/tex]
Now, partial pressure of mixture of gas containing gas A = [tex]P_{A}[/tex]
partial pressure of mixture of gas containing gas B = [tex]P_{B}[/tex]
Total pressure of gas = 5.60 atm
Pressure of gas [tex]P_{A}[/tex] = 0.40 atm
[tex]P_{total}[/tex] = [tex]P_{A}[/tex] + [tex]P_{B}[/tex]
5.60 atm = 0.40 atm + [tex]P_{B}[/tex]
[tex]P_{B}[/tex] = 5.60 - 0.40 = 5.2 atm
So, the partial pressure of gas B is 5.2 atm.

The instrument used to measure atmospheric pressure specifically in the area of meteorology is Barometer.
A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure. Atmospheric pressure is an indicator of weather. Changes in the atmosphere, including changes in air pressure, affect the weather. Meteorologists use barometers to predict short-term changes in the weather. A barometer measures atmospheric pressure in units of measurement called atmospheres or bars. An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit).

The number of liters of acid needed for all of the hot tubs is the total volume of muriatic acid, which is 31, 155 ml.
Volume refers to the space occupied within the boundaries of an object in three-dimensional space. It is also called as the capacity of the object. In an object is filled with a liquid complete, there volume is the same.
In the given case that total volume of the acid would be the product of volume of each hot tub and number of hot tub containers. Hence, it is given by:
Total volume = Volume of each hot tub x number of hot tub containers
According to the given data:
Volume of each hot tub = 115 ml
Number of hot tub containers = 297

Molar concentration is a unit of measurement for the concentration of a chemical species, specifically a solute, in a solution, expressed as the amount of substance per unit volume of solution. The most commonly used unit for molarity in chemistry is the number of moles per liter, denoted by the unit symbol mol/L or mol/dm³ in SI units.
Molarity (M) is the most commonly used unit of solution concentration and is defined as the amount of solute in moles divided by the volume of solution in liters:
M = moles of solute/liters of solution.
A mole is a unit of measurement for a chemical substance, from which the term "molarity" derives.
