Yes but Hydrogen is a gas and there is no such thing as gaseous metalloids, therefore it is a non-metal
The ideal gas law states that the relationship between partial pressure and volume is inverse. Additionally, it relates temperature and moles in a direct proportion. The partial pressures of the gases are found to be PN2 = 0.094 atm, PH2 = 0.039 atm, and PNH3 = 0.003 atm in the following reaction at equilibrium at room temperature.
<h3>What is ideal gas law ?</h3>
PV = NkT, where P is a gas's absolute pressure, V is the volume it occupies, N is the quantity of atoms and molecules in the gas, and T is its absolute temperature, is the formula for the ideal gas law.
Equal volumes of two gases with the same temperature and pressure will contain an equal number of molecules, according to the law. The ideal gas law is the result of the union of all these relationships.

Answer:
Number of Protons = 19
Number of Neutrons = 25
Number of Electrons = 19
Explanation:
Number of Protons:
The number of protons present in any atom are equal to the atomic number of that particular atom. Hence, as the atomic number of Potassium is 19 therefore, it contains 19 protons.
Number Neutrons:
The number of neutrons present in atom are calculated as,
# of Neutrons = Atomic Mass - # of protons
As given,
Atomic Mass = 43
# of Protons = 19
So,
# of Neutrons = 43 - 19
# of Neutrons = 24
Number of Electrons:
As we know for a neutral atom the number of electrons are exactly equal to the number of protons present in its nucleus. So, for 19 protons in neutral Potassium atom there must be 19 electrons.
Answer:
Positive
Explanation:
For the most effective hot pack, the temperature change should be <u>positive</u>.
<em>Hot packs are generally utilized for their heat-producing abilities. Hence, the reactions leading to the activation of hot packs are usually exothermic, that is, heat energy generating. In other words, positive or increased temperatures must be generated when hot packs are activated.</em>
This is unlike cold packs which are utilized for the cold-generating abilities. Reactions leading to their activations must be endothermic, that is, heat-absorbing.
Answer:
La constante de equilibrio (K) se expresa como la relación entre las concentraciones molares (mol/l) de reactivos y productos. Su valor en una reacción química depende de la temperatura, por lo que ésta siempre debe especificarse.
