<span>*Acids taste sour. The lemon, vinegar, tamarind contain acids; that's why they are sour.
*The acids change the color of certain substances called indicators. The indicators have the property of changing color as the character acid or basic solutions. The litmus and phenolphthalein are indicators of acids and bases. The solution of phenolphthalein is colorless red in the presence of an acid. Already the blue litmus paper turns red.
*The acids react with bases to form salts and water. This reaction is called neutralization reaction.</span>
hope this helps!
Volume of the metal = change in volume reading
Volume = 37.4 - 33
Volume = 4.4 ml
Density = mass / volume
Density = 7.101 / 4.4
Density = 1.61 g/ml
Answer:
El volumen final del sistema es 1.2L
Explanation:
La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:
V₁/T₁ = V₂/T₂
<em>Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.</em>
<em />
Reemplazando:
V₁ = 1.3L
T₁ = 50°C + 273.15K = 323.15K
V₂ = Incógnita
T₂ = 300K
1.3L/323.15K = V₂/300K
1.2L = V₂
<h3>El volumen final del sistema es 1.2L</h3>
Answer
Ionic compounds are formed when metals react with non-metals . Ionic compounds held together by ionic bonds are classed as ionic compounds.
