Answer:
That involve the complete transfer of an electron from one atom of an element to another
Answer:
A 12 oz Coca Cola contains 39g of sugar or C6H12O6.
To calculate for the molarity of sugar in the soda, convert 39 grams of sugar to moles sugar:
39g/ 180.16 g/mol = 0.216 mol sugar
then, convert 12 oz to L:
12oz / (1oz/0.02957L) = 0.35484 L
therefore the concentration of sugar in the soda is:
M = mol sugar / L sol'n
= 0.216 mol sugar / 0.35484 L
= 0.609 M
Explanation:
Answer:
At -13 , the gas would occupy 1.30L at 210.0 kPa.
Explanation:
Let's assume the gas behaves ideally.
As amount of gas remains constant in both state therefore in accordance with combined gas law for an ideal gas-
where and are initial and final pressure respectively.
and are initial and final volume respectively.
and are initial and final temperature in kelvin scale respectively.
Here , , , and
Hence
So at -13 , the gas would occupy 1.30L at 210.0 kPa.
Answer:
C
Explanation:
The charge on an atom depends on the number of protons and electrons present in it. The protons in an atom are positively charged while electrons have a negative charge. For a neutral atom, the number of protons balances the number of electrons. for a negatively charged atom, the number of electrons is more than the number of protons. for a positively charged atom , the number of protons are more than the number of electrons.
