How many moles of h2 gas would be contained in 4.00 of the gas at 202.6KPa and 127c?
JulsSmile [24]

Answer : The volume of one mole of gas is dependent of temperature and pressure.

Explanation:

At <span><span>0o</span>Cand1atm</span> one mole of an ideal gas would be <span>≈22.4L</span>, which is the same as <span>22.4d<span>m3</span></span>

If you double the pressure, the same amount (mole) of gas would take up only half the space.

If the temperature changes (and pressure stays constant), the gas will expand or contract by about <span>1%/<span>3o</span></span>.

The hydrogen atom, changing from its first excited state to its lowest energy state, emits light with a wavelength of 122 nm. Th
tatyana61 [14]

Answer:

true b and c

Explanation:

n the electromechanical transitions of the atoms the relationship must be fulfilled

        \frac{x}{\lambda } = R (1 / nf - 1 / no²)

where for the final state nf = 1 giving in the case of hydrogen the Lymma series whose smallest wavelength is lam = 122 nm with nf = 1 and there are a series of spectral lines for each value of n of the final state

in the case of sodium so well it has a transition from an excited state to the kiss state (bad)

Now let's review the different proposals

a) False. The electronic potential for sodium is much lower than for hydrognosia

b) True

c) True

d) true

7. How do Newton’s laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can pass a
Arisa [49]
The first law states that “objects at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force”. Keeping the ice smooth will make sure there is not friction, friction would slow the puck down
