En una solución acuosa donde el agua es el solvente, el soluto que será disuelto por el agua tiene menos partículas, lo que hace que las partículas se muevan en un movimiento aleatorio. El agua pura tiene una baja concentración de iones y, por lo tanto, no conduce electricidad.
The balanced reaction is given as:
<span>2Ca(s)+O2(g)→2CaO(s)
</span>
We are given the amount of oxygen gas to be used for the reaction. This will be the starting point of our calculations.
0.016 mol O2 ( 2 mol CaO / 1 mol O2 ) = 0.032 mol CaO
<span>Therefore, for the reaction, the amount of calcium oxide produced is 0.032 moles.</span>
Answer:
A. The sum of the voltages of the half-reactions is positive.
Explanation:
correct on a p e x
The answers is 3.0 g/cm^3
Explanation:
You use the formula
Density= mass/volume
When they give you mass and volume.
The mass is 15 grams and the volume would be 5 cm^3.
So the density would be
15/5= 3
