Answer: Areas surrounded by water would have less of a change in temperature
throughout the year.
Explanation: Water has a higher specific heat index so it's temperature will be slow to rise. Water also holds heat longer than most material hence areas sorrounsing water will have less temperature change throughout the year.
It means that is it a sugar molecule
<u>Answer:</u> The moles of given hydrocarbon is 0.3 moles
<u>Explanation:</u>
To calculate the number of moles, we use the equation:

We are given:
Given mass of ethane = 10.0 g
Molar mass of ethane = ![[(2\times 12)+(6\times 1)]=30g/mol](https://tex.z-dn.net/?f=%5B%282%5Ctimes%2012%29%2B%286%5Ctimes%201%29%5D%3D30g%2Fmol)
We need to divide the given value by the molar mass.
Putting values in above equation, we get:

In case of multiplication and division, the number of significant digits is taken from the value which has least precise significant digits. Here, the least precise number of significant digits are 1.
Hence, the moles of given hydrocarbon is 0.3 moles
1 electron. Look at the periodic table, fluorine (F) is on the right, atomic number 9. It wants to get all the way over to the right to become more stable, which means it only needs 1 more electron (has 7 in its current state, wants 8)
