Answer:
D i think, sorry if its wrong
Explanation:
The balanced chemical
reaction will be:
2H2O = 2H2 + O2
<span>We are given the amount of water used in the decomposition reaction. This will be our
starting point.</span>
<span>17.0 g H2O</span> (1 mol H2O/ 18.02 g H2O) (1 mol O2/2
mol <span>H2O</span>) ( 32.00 g O2/1mol O2) = 15.09 g O2
Percent yield = actual yield / theoretical yield x 100
<span>Percent yield =10.2 g / 15.09 g
x 100</span>
Percent yield = 67.58%
Answer:
P.E for the 4kg bowling ball held 2.5 meters above head is 100j, while the other is 60j so the 4kg ball has more potential energy

I really need help
Answer:
108.81 K
Explanation:
First convert 17 °C to Kelvin:
Assuming ideal behaviour, we can solve this problem by using the<em> combined gas law</em>, which states that at constant composition:
Where in this case:
We <u>input the data</u>:
- 800 torr * 100 L * T₂ = 600 torr * 50 L * 290.16 K
And <u>solve for T₂</u>:
