Molar mass :

H₂O = 18.0 g/mol
O₂ = 32.0 g/mol

<span>2 C</span>₄<span>H</span>₁₀<span> + 13 O</span>₂<span> = 8 CO + 10 H</span>₂<span>O
</span>
13 x 32.0 g O₂ ------------- 10 x 18.0 g H₂O
            ? g O₂ ------------- 2.46 g H₂O


Mass O₂ = 2.46 x 13 x 32.0 / 10 x 18.0

Mass  O₂ =1023.36 / 180

=> 5.68 g of O₂

hope this helps!

as you move down a group in the periodic table, atomic size generally a. increases. b. decreases. c. remains the same. d. varies
Helen [10]
The atomic size / radius generally increases, as when we move down the group, it means that there is an additional shell compared to the last element. For example, K has one more electron shell than Na does, so the atomic size generally increases as we move down a group in the periodic table.

The air pressure in a tire is 2.38 atm. What is the pressure in kilopascals.
Anna71 [15]

Answer:

The answer is

<h2>241.15 kPa</h2>

Explanation:

To find the pressure in kilopascals we must first find the pressure in Pascal

To find the pressure in Pascal we use the conversion

1 atm = 101 , 325 Pa

If 1 atm = 101325 Pa

then 2.38 atm = 2.38 × 101325

= 241153.5 Pa

Converting it into kPa we have the final answer as

<h3>241.15 kPa</h3>

Hope this helps you
