Turns into vapor. not all of the molecules are liquid have the same energy
Answer: Only I and V are true statements concerning chemical equations
Explanation: II subscripts cannot be fractions and coefficients represent the number of moles of reactants and/or products. Subscripts cannot be changed but coefficients can.
<span>The effective nuclear charge of an atom = total electrons - inner electrons
For O, ENC = 8 - 2 = 6
For Li, ENC = 3 - 2 = 1
For C, ENC = 6 - 2 = 4
The electrons in O experience the greatest effective nuclear charge and that is why O is smaller than C (which is smaller than Li).</span>
Answer:
0.66g/mL
Explanation:
La densidad es una propiedad de la materia definida como la masa de una sustancia en un determinado volumen.
En este problema, podemos hallar la densidad sabiendo que la diferencia de masas del pic vacío y el pic lleno es la masa de la solución y que el volumen que ocupa es de 25mL:
<em>Masa solución:</em>
25g - 8.5g = 16.5g
Así, la densidad será:
16.5g / 25mL =
<h3>0.66g/mL</h3>
Answer:
1/45 or 0.0222 g/s
Explanation:
rate of reaction = quantity of reactant used/time taken
= (10-8)/90
= 1/45 or 0.0222 g/s
