Answer:
To make this easier I'll label the left column 1, 2, 3, and 4. and the right column A, B, C, and D.
1 goes to B
2 goes to A
3 goes to C
4 goes to D
Explanation:
1. A ship goes out of sight on the horizon because it goes too far around the curve of the earth to see anymore.
2. We have day and night because the earth spins certain sides of itself to face the sun and other sides to face away from the sun (aka day and night)
3. We have summer and winter because Earth's axis is tilted. Part of the Earth tilts closer to the sun when summer is here, and the other part tilts away from the sun when it's winter. (This is why it's summer in North America, when it's winter in Australia).
4. A year is measured by how long it takes a planet to orbit it's star. A year for Earth is 365 days because it takes 365 days for earth to orbit around the sun.
Molar mass:
O2 = 16 x 2 = 32.0 g/mol Mg = 24 g/mol
<span>2 Mg(s) + O2(g) --->2 MgO(s)
</span>
2 x 24.0 g Mg -------------> 32 g O2
5.00 g Mg -----------------> ( mass of O2)
mass of O2 = 5.00 x 32 / 2 x 24.0
mass of O2 = 160 / 48
= 3.33 g of O2
hope this helps!
Answer: mass of SO2 is 160 g
Explanation: according to equation number of moles of SO2
Is same as amount of Oxygen, also 2.5 moles.
Molar mass of SO2 is 32.07 +2·16 = 64.07 g/mol
Mass is m= nM = 2.5 mol· 64.07 g/mol= 160.175 g
Answer:
Yes!

I think It would be fun!, Going thought space going from planet to planet. once i get back to earth i can make a document about my time in space.
