Allushta [10]

Answer:

Anita did not make the track team this year, and she feels really disappointed and upset. What question would most likely redirect her thinking and provide a solution?

Why did this terrible thing happen to me?

What other sports can I try this spring?

Why does everything I attempt go wrong?

Why did Karen get on the team but I didn't?

Answer - What other sports can I try this spring?

Explanation:

Failures and successes are part of our daily lives as humans. It can be very challenging for one to accept his or her failures and bring oneself above it.

when failure occur, the best way to reverse the negative impacts it brings is to move forward and decide on what next to do.  

The actions that must be taken in the processes should be quite productive enough to bring back the results one desired.

When the effects of failures prove irreversible, one would then give the mind a diversion and help his or herself think their way though the failure that was encountered.

What volume of methanol should be used to make 1.25 L of a 21.0% by volume solution?<br> ___ mL
o-na [289]

Answer:

V CH3OH = 262.5 mL

Explanation:

  • %v/v = (v compound / v sln)×100

∴ %v/v = 21.0 %

∴ v sln = 1.25 L

⇒ v compound = ?

⇒ 21.0 % = ( v compound / 1.25)×100

⇒ 0.21 = v compound / 1.25 L

⇒ (0.21)*(1.25 L) = v compound

⇒ v compound = 0.2625 L = 262.5 mL

A person has 5.0 liters of blood which contains 95 mg of glucose per 100 ml. What is the total mass of glucose (in grams) in the
vampirchik [111]
Use conversion factors to calculate this answer. Since there are 1000 ml in a liter, this means that there is 95 mg of glucose in 0.1 liter. To add on, since there is 1000 mg in a gram, this means that there is 0.095 grams in 0.1 liters. 5 liters of blood is 0.1 x 50 = 5.0. Hence, you would need to multiply 0.095 x 50, which is equates to about 4.75 grams of glucose in 5.0 liters of blood.

Don’t forget the significant figures, 4.75 is rounded to 4.7 because the significant figures in this case is 2 sig figs (5.0 liters of blood).
