Why does the moon and the earth have the same mass
Evgesh-ka [11]

Answer:

Moon rocks contain few volatile substances (e.g. water), which implies extra baking of the lunar surface relative to that of Earth. The relative abundance of oxygen isotopes on Earth and on the Moon are identical, which suggests that the Earth and Moon formed at the same distance from the Sun.

What makes this inauguration different from the past?
Sveta_85 [38]

Answer:

there's just a lot of drama around grumpy trumpy's StOlEN eLecTiOn which are all just fake claims. all his hardcore followers are brainwashed into believing anything he says, so people (especially people who are inside the capitol) fear that trump's followers might incite violence AGAIN even after they broke into the Capitol on the 6th.

That's why they have the National Guard and thousands of people to keep the building secure during Biden's Inauguration.

hope this helps!

What is the mole ratio of N2 to NO2 in the question ... N2 + 2O2-&gt; 2NO2
GREYUIT [131]
The reaction equation is already balanced. So the mole ration of reactants and production is the ratio of the coefficients. So the mole ratio of N2 to NO2 is 1:2.
