Answer:
The correct answer is c. adding a catalyst for the reaction
Explanation:
The function of a catalyst in a chemical reactionis to increase the rate of reaction by decreasing the required activation energy which is clearly illustrated on energy diagrams. It is not consumed in the reaction and can be reused repeatedly,as such, only small quantities of catalysts are required in the reaction. Catalyst provide a separate route for a chemical reaction to proceed at a lower activation energy than an uncatalysed reaction
The process of speeding up a chemicals reaction by the addition of a catalyst is known as catalysis

<h2>d=density, m=mass, v=volume</h2>
1. 17.2kg=17200g
so knowing that d=m/V, use V=m/d to calculate the volume
v=17200/5.75
and then devide by 1000 to convert cm3 to dm3 and the answer will be in dm3
2. d=m/v
v=0.5l
m=425g
so use the formula and you will get d=425/0.5=850g/l
3. use d=m/v again, but not before rewriting the formula for volume: m=vd and convert dm3 to cm3
1dm3=1000cm3
so 0.987dm3 =987 cm3
now m=987cm3 * 10.5g/cm3 and the answer will be in grams
Answer:
El ciclo hidrológico comienza con la evaporación del agua desde la superficie. A medida que se eleva, el aire humedecido se enfría y el vapor se transforma en agua: es la condensación. Las gotas se juntan y forman una nube. Luego caen por su propio peso: es la precipitación
