Answer:

Ver explicación

Explanation:

La reacción; Mg + H2SO4 →

MgSO4 + H2 es una reacción de sustitución simple.

En una reacción de sustitución, un átomo o grupo en un compuesto se reemplaza por otro, como podemos ver claramente. el hidrógeno en el ácido fue reemplazado por Mg.

2A1 + 2HCl → 2AICI + H2 sigue la ley de conservación de la masa porque el mismo número de átomos de cada elemento se encuentra en ambos lados de la ecuación de reacción, por lo que la masa no se creó ni se destruyó.

Recommend THREE ways that men can challenge the idea of toxic masculinity within
their group of friends. In your answers, also indicate how EACH of these recommendations
could lead to a broader and healthier definition of masculinity within the friend group.​

Answers

Answer:

They could talk more openly about their health, both physical and mental. Men are typically expected not to show emotion or weakness, so opening up like that could be very helpful. They could call out their friends when they make misogynistic remarks. A man hearing another man say that misogyny isn't okay might make them realize that misogyny isn't okay. And finally, take time to have a discussion about societal norms and question whether they really make sense. The more you question the "normal", the more you wonder why it's considered normal. Society could really benefit from more men challenging their own masculinity.

Even though Mexico became independent in 1821, people of Spanish origin still held most of the power. In fact, even though they were only one percent of the population, they owned 85 percent of the land! These rich estates were known as haciendas. The wealthy people ruthlessly stole almost all the land from the natives and mestizos. Under the independent power, the new improvements really only benefited rich people. Emiliano Zapata led a group of peasants in revolt against this new, unequal independence in 1910. He wanted to return the land to peasants, so he led the burning of hacienda buildings to bring them back to traditional communities. Francisco "Pancho" Villa also led revolts against the haciendas, though he didn't burn them. Zapata and Villa gained many followers, but the Creole landowners had control of the cities. They eventually killed Zapata and Villa. The landowners knew that they couldn't continue to rule without winning more support from the people, so they gave back a little bit of land. The vast majority of Mexicans remained poor.According to the passage, when Mexico became independent,A. the benefits were felt mostly by the rich people.B. the peasants gained total control of the government.C. haciendas were available for peasants to buy.D.
