it depends on their size and how close they are to earth but I think A. an explosion

Explanation:

When asteroids collide, the resultant fragments are ejected with velocities that are small compared to the orbital velocity of the original asteroid which would probably be a pretty cool sight to see

What is the volume of 0.80 grams of O2 gas at stp?

sergey [27]

Answer: The volume occupied by $O_2$ at STP is 0.56 L.

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Given mass of oxygen = 0.80 g

Molar mass of oxygen = 32 g/mol

Putting values in above equation, we get:

$\text{Moles of oxygen}=\frac{0.80g}{32g/mol}=0.025mol$

At STP:

1 mole of a gas occupies 22.4 L of volume.

So, 0.025 moles of oxygen gas will occupy = $22.4\times 0.025=0.56L$ of volume.

Hence, the volume occupied by $O_2$ at STP is 0.56 L.
