B. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.
Explanation:
The best statement that describes the collision of gas particles according to the kinetic-molecular theory is that as particles travel in straight lines, their paths sometimes meet and then they bounce apart with no gain or loss of energy.
- The kinetic molecular theory is used to explain the forces between molecules and their energy.
One of the postulate suggests that, when molecules collide with each other, or with the wall of the container, there is no loss or gain of energy.
- Molecules are independent of one another and that forces of attraction and repulsion between molecules are negligible.

<span>The correct answer would be the fourth option. The compounds ethanol and 1-propanol are soluble to both water and hexane. Ethanol and 1-propanol are completely soluble in water as they both contain a polar end due to the hydrogen bonding present in the -OH functional group. Both are soluble in hexane since both contains a non polar end, the aliphatic hydrocarbon chain. Solubility of alcohols varies increasingly as the hydrocarbon chain increases since it makes them more non polar. However, for branched molecules, non polar properties would decrease. So, the best option from the list of choices would be ethanol and 1-propanol.</span>
Answer: concentration of solutions are expressed in various ways mol/L, mol/dm3, g/L etc
Explanation:
Respuesta:
968 g Ca(OH)₂
Explicación:
Paso 1: Calcular la masa de solución
Tenemos 1500 mL de una solución cuya densidad es 1.17 g/mL, es decir, 1 mL de solución tiene una masa de 1.17 g.
1500 mL × 1.17 g/mL = 1.76 × 10³ g
Paso 2: Calcular la masa de hidróxido de calcio en 1.76 × 10³ g de solución
La solución tiene una concentración de 55% en masa de hidróxido de calcio, es decir, cada 100 gramos de solución hay 55 gramos de hidróxido de calcio.
1.76 × 10³ g Solución × 55 g Ca(OH)₂/100 g Solución = 968 g Ca(OH)₂
