Answer:
Cs is cesium and CrO₄ is chromate so CsCrO₄ is cesium chromate.
Depending on the size of the object, that system may describe it

<u>Given:</u>
Molar mass (Mr) of ethanol = 46.07 g/mol
<u>Question:</u>
How much energy is required to vaporize 98.6 g of ethanol (C₂H₅OH) at its boiling point?
<u>The Process:</u>
Observe this . This means that 40.5 kJ of energy is required to vaporize every 1 mole of ethanol at its boiling point. Therefore we must first convert grams into moles.
<u>Question:</u>
Step-1:
Let us count the number of moles of 98.6 g of ethanol.
We obtain 2.14 moles of ethanol.
Step-2:
Let us calculate how much energy is required to vaporize 2.14 moles of ethanol at its boiling point.
The amount of energy required is
Thus, the amount of energy required to vaporize 98.6 g of ethanol at its boiling point is 86.7 kJ.

Answer:
Reaction time tests can be used to assess an individual's hand-eye coordination. One test involves catching a 1 metre ruler and measuring the distance, d in metres, that the ruler travelled before being caught. The reaction time t seconds is then calculated using the formula: = √2d/9.8
