The speed of shanghai magleve is 251.5 miles per hour and harmony CRH speed is 220.5 miles per hour
Let five moles of oxygen are required to react with 2 moles of acetylene. So, doing a rule of three, we are going to obtain :
5 moles of Oxygen => 2 moles of C2H2
? O2 => 1 mole of C2H2
1.0 mole C2H2×(5 moles O2/2 moles of C2H2) = 2.5 moles of O2
So, the answer is <em><u>2</u></em><em><u>.</u></em><em><u>5</u></em><em><u> </u></em><em><u>m</u></em><em><u>o</u></em><em><u>l</u></em><em><u>e</u></em><em><u>s</u></em><em><u> </u></em><em><u>o</u></em><em><u>f</u></em><em><u> </u></em><em><u>o</u></em><em><u>x</u></em><em><u>y</u></em><em><u>g</u></em><em><u>e</u></em><em><u>n</u></em> are required to react with 1 mole of acetylene.
Answer:
5.67
Step-by-step explanation:
- 68.0052 divided by 12 = 5.6671
- The hundredth place is two digits to the right of the decimal point.
- To round this look at the third number to determine whether the 6 in 5.6<u>6</u>71 is rounded to 7.
- The third digit to the right of the decimal is greater than 5 so the number is rounded to 5.67
