Answer:
0.0196
Explanation:
The Total volume of the solution = Volume of 
= 10 mL + 10 mL + 10 mL+ 10 mL + 1 mL + 10 mL
= 51 mL
The concentration of ![[H^+] = \dfrac{ mL \ used \times 0.1 \ M}{total \ volume}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%20%3D%20%5Cdfrac%7B%20mL%20%5C%20used%20%5Ctimes%200.1%20%5C%20M%7D%7Btotal%20%5C%20volume%7D)
= 0.0196
2N2 + 3O2 ---> 2NO + 2NO2
You should do it based on moles and not grams.
1.14 g O = 0.071 moles O
1 g N = 0.071 moles N
So in NO2 you need 2 moles O for each mole of N
1 g N = 0.071 moles, so you need 0.071 x 2 moles of O = 0.0.142 moles O
0.142 moles O x 16 g/mol = 2.27 grams of O. So, you are actually correct because your answer is 2.28 grams. I just prefer to work it out in moles so it makes perfect chemical sense.
Explanation:
b. Bromo cyclopentane + HBr
0 K in Celsius scale is -273 degree Celsius and in Fahrenheit scale 459 degree F.
The degree of a body's heat or cold is referred to as the gas's temperature. It is stated in temperature units such as, degree Celsius, Fahrenheit and Kelvin these temperature units are interchangeable. To convert Celsius to Fahrenheit ° F = 9/5 ( ° C) + 32, kelvin to Fahrenheit= ° F = 9/5 (K - 273) + 32, Celsius to kelvin K = ° C + 273. to convert Fahrenheit to Celsius ° C = 5/9 (° F - 32) In this question, to convert Fahrenheit to Celsius ° C = 5/9 (° F - 32) = 0-273 K (5/9 - F-32) =459 degree F. and kelvin to Celsius K - 273 = C = -273 degree Celsius
At 8^0C K= 8 + 273 =281 degree Celsius and at 8F , 8= 9/5(k-273) +32 =453 F
