Answer:
Summer
Explanation:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Answer:
C2H3O3
Explanation:
Empirical formula is the simplest whole number ratio of moles of atoms that you can find in a molecule.
In combustion analysis all Carbon reacts producing CO2 and all hydrogen reacts producing H2O. With the differences in masses we can find the mass of oxygen and their moles:
<em>Moles CO2 = Moles C:</em>
14.08g * (1mol/44.01g) = 0.3199 moles C * (12.01g/mol) = 3.8423g C
<em>Moles H2O:</em>
4.32g H2O * (1mol/18.01g) = 0.2399 moles H2O * (2mol H / 1molH2O) = 0.4797moles H = 0.4797g H
<em>Mass O:</em>
12.01g = Mass O + 3.8423g C + 0.4797g H
Mass O = 7.688g O
<em>Moles O:</em>
7.688g O * (1mol/16g) = 0.48 moles O
The ratio of atoms (Dividing in the moles of C that are the lower number of moles):
O: 0.48moles O / 0.3199 moles C = 1.50
C: 0.3199 moles C / 0.3199 moles C = 1
H: 0.4797 moles H / 0.3199 moles C = 1.50
As empirical formula requires whole numbers:
O: 1.50* 2 = 3
C: 1*2 = 2
H: 1.50*2 = 3
The empirical formula is:

Coffee creamer is a base because if you eat it raw then it will soak up the acid in your stomach.
Ooooh, i know this x'D.
There are 4 quarts in a gallon. So 2(Gallons)*4(Number of quarts per gallon) equals 8. Then we have 1/4th left, since there are 4 in each gallon, this 1/4th is a quart. Long explanation short......2*4=8+1=9
9 Quarts.
