If each gas sample has the same temperature and pressure, which has the greatest volume? Since hydrogen gas has the lowest molar mass of the set, 1 g will have the greatest number of moles and therefore the greatest volume. What is the Ideal Gas Law?

Answer:

0.600

Explanation:

2.120/3.670 = 0.578 so 790*0.578 = 456.349 when converted to atm that is 456.349/760 = V2

How does the altitude of the Sun change throughout the year in Reno, NV?
vampirchik [111]

Given what we know, we can confirm that in Reno, NV, the angle of the Sun is lower during the winter months and <u>higher </u>in the <u>sky </u>during the summer.

<h3>How can we know this?</h3>

We can know this about Reno, NV, given that it is irrelevant where we placed this question. the answer will be the same all across the world. It has to do with the way the Earth orbits the Sun as well as the tilt of the Earth. This causes the Sun to be higher in the sky during summer and lower in the winter months.

Therefore, we can confirm that the angle of the Sun is lower during the winter months and higher in the sky during the summer, both in Reno, NV and everywhere else.

Calculating kinetic energy 1200kg car moving at 10​
valkas [14]

Answer:

60000J

Explanation:

Given parameters:

Mass of car  = 1200kg

Speed  = 10m/s

Unknown:

Kinetic energy  = ?

Solution:

The kinetic energy is given as:

   Kinetic energy  = \frac{1}{2}  m v²  

Now insert the parameters and solve;

   m is the mass

    v is the velocity  

 Kinetic energy  =  \frac{1}{2} x 1200 x 10²   = 60000J

In what orbital would to valence electrons of strontium be found? a.) 5s b.) 4s c.) none d.) 5p​
KonstantinChe [14]

Answer:

The correct answer is 5s

Explanation:

Strontium atomic number = 38

Electronic configuration is $1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 3d^{10} 4s^{2} 4p^{6} 5s^{2}

As $5s$ orbital is valence orbital in strontium, the outer electrons exists in that orbital only.
