Answer:
Hydrogen gas is highly combustible, and leakage can lead to a catastrophic explosion. The concentration of hydrogen gas in the furnace is held constant at 6.022 x 1023 atoms/m3 and is effectively 0 outside the furnace. Calculate the mass flow rate (mg/hr) of hydrogen from the furnace if the diffusivity of hydrogen through the glass is 2 x 10-5 m2 /s. You may assume steady state behavior and constant diffusivity. You may assume that diffusion only occurs through the glass. The molar mass of hydrogen can be taken as 2 g/mol

Answer:
Group 17, 2, 7, 7 electrons
Explanation:
An acid is a compound which will give H+ ions or H3O^+ ions
the reaction will be
![[Mn(H_{2}O )_{6} ^{+3} +H_{2}O --> [MnOH(H_{2}O)_{5}]^{+2} + H_{3}O^{+}](https://tex.z-dn.net/?f=%5BMn%28H_%7B2%7DO%20%29_%7B6%7D%20%5E%7B%2B3%7D%20%2BH_%7B2%7DO%20--%3E%20%5BMnOH%28H_%7B2%7DO%29_%7B5%7D%5D%5E%7B%2B2%7D%20%2B%20H_%7B3%7DO%5E%7B%2B%7D)
Thus as there is evolution of H_{3}O^{+} the Mn+3 is an acid
Answers:
1. B.)
2. Both A.) and B.)
3. A.)
Step-by-step explanation:
1. Ions in gas phase
A plasma is a gas consisting of electrons and positively charged ions.
Because the particles are ions and electrons, rather than neutral atoms or molecules as in ordinary gases, scientists consider a plasma to be a fourth state of matter<em>.</em>
2. Kinetic Molecular Theory
Both activities illustrate the postulate.
A.) If the particles are extremely small and far apart, most of the volume of a gas is empty space. That's why it's easy to push the plunger of a capped nozzle syringe containing a gas.
B.) If the particles are far apart, it's easy for a coloured gas to spread into an inverted jar placed on top of a jar containing the gas.
3. Hot air balloon
The high temperature in the balloon makes the gas molecules spread apart according to Charles's law, because this law describes how a gas will behave at constant pressure.
As the hot air escapes from the vent, the combined mass of balloon + hot air becomes less than the mass of cold air that it displaces, and the balloon rises.
B.) is <em>wrong</em>. Boyle's law applies only when both the number of moles and the temperature remain constant.
