d1i1m1o1n [39]3 years ago
3 0
Molar{Mass} H_{2}O_{2} =2*16.0+2*1.0= 34.0 g/mol

42.0 g H_{2}O_{2}* \frac{1 mol H_{2}O_{2}}{34.0 g H_{2}O_{2}} = 1.24 mol H_{2}O_{2}

2H_{2}O_{2} --\ \textgreater \ 2 H_{2}O +O_{2}
\\2 mol  ----2 mol   (from// reaction)

\\1.24 mol ---1.24 mol (from  the problem)

Answer: 1.24 mol H_{2}O.

Which of Newton's Three Laws is BEST described by the following statement: A ball dropped from the 10th story of a hotel had mor
Zolol [24]

Answer:

I believe the answer is Newton's Second Law

Explanation:

Newton's Second Law states that the acceleration of an object will count on how much mass and the amount of force that is applied.

The bowling ball was dropped from the 10th story window and had more force than when the ball was dropped from the 5th story window because the 10th story window gave the bowling ball more acceleration.

If the titrant has a molarity of 0.1000 m and there are 45.00 ml of analyte present, what is the molarity of the analyte?
marysya [2.9K]
Given: 

Concentration of titrant = 0.1000 M
Volume of titrant = 45 mL

The molarity of analyte depends on the amount of the analyte present in the titrated solution. If the amount of analyte is 20 mL, then its concentration is:

45ml * 0.10 M = C analyte * 20 ml

C analyte = 0.225 M
