Why does the reaction rate increase when a catalyst is added

Answers

Answer 1

A catalyst can be a chemical or biological in nature but its role always remain same "to increase reaction rates and the method vary from other ways of hiking reaction rate". Its intention is to reduce the activation energy, so that a larger proportion of the particles has enough energy to react.

Explain your answer in complete sentences.

Answers

The colonists' anger toward the British Parliament led to the organization of the First Continental Congress and British parliament and King George III were not happy with the colonists but were annoyed.

Explanation:

It may appear that all the criticisms of the colonists were against King George but the reality is not that. The colonists specifically blamed the parliament for not giving representation of the colonists in the British Parliament. This annoyed the colonists.

The colonists were relentlessly oppressed by the taxes and they were not given an ear to listen their grievances from their perspective and slowly until the second continental congress was formed and colonists were trying to appeal the King with 'Olive branch Petition'. King rejected their appeal and this finally enraged the colonists who plunged into protests and intended secession from the Crown.

create a political cartoon that shows why casework is such an important aspect of being an effective legislator

Answers

Answer:

Explanation:

Final answer:

Casework refers to the tasks a legislator handles to help constituents with various issues. A cartoon could depict a legislator using casework to build a bridge, connecting them to their constituents. This illustrates how casework plays a crucial role in addressing local issues while strengthening the connection between legislators and their constituents.

Explanation:

In a political context, casework is a critical aspect of a legislator's role. It pertains to the work that a legislator does to help constituents resolve issues they face with government agencies or procedures. This is a vital role because it helps build trust and rapport with constituents, directly impacting the local community's needs.

A cartoon illustrating this could depict a legislator standing on one side of a chasm, with constituents on the other side. Between them is a bridge being built out of bricks, symbolizing 'caseworks' with each brick named after a solved case. This would emphasize how casework connects legislators to their constituents, bridging gaps and addressing local issues head-on.

Legislators not only create and vote on laws at a higher level but, through casework, ensure they effectively serve their local constituent's needs and concerns as well. So, while a legislator's job may encompass policy-making, casework demonstrates their capacity to enact positive change at the grassroots level which is often'reflected in their re-election success.

What major international event did the fall of the Berlin Wall precipitate?

Answers

The fall of the Berlin Wall in 1989 precipitated the end of the Cold War, the collapse of Communist governments across Eastern Europe, and ultimately the disintegration of the Soviet Union. It marked a new era in international relations and signaled the victory of liberal democracy over socialism.

The fall of the Berlin Wall in November 1989 precipitated the end of the Cold War and the subsequent collapse of the Soviet Union. This event was a pivotal moment in the history of the 20th century, marking the decline of communism in Eastern Europe and the shift towards democratic governance and market economies.

The Berlin Wall had long stood as a symbol of the division between East and West, and its demolition was seen globally as the beginning of a new era of international relations and a victory for liberal democracy over socialism.

Revolutions in Eastern Europe followed the fall of the wall, most of which were peaceful. These revolutions swept through countries such as Poland, Hungary, Czechoslovakia, Bulgaria, and Romania, leading to the collapse of Communist governments and eventually the disintegration of the Soviet Union itself. Mikhail Gorbachev's policies of glasnost (openness) and perestroika (restructuring) also played a significant role in this transformative period.

The immediate aftermath of the wall's destruction saw the reunification of Germany and the dissolution of the Warsaw Pact. By 1991, the Baltic States regained independence and the former communist bloc countries began the transition to democracy and integration into Western institutions.

The fall of the Berlin Wall was not just the culmination of the desires of the East German people for freedom of movement and reform, but it also signaled the beginning of a new world order and the end of the bi-polar power structure that had dominated global affairs since the end of World War II.

mention the impact of appropriate age at marrige on population management​

Answers

It controlled the birth rate. And it also helped in the control of health, because getting married too soon impaired the health of people, especially women. Also, education was able to improve.

Appropriate age at marriage contributes to population management by aligning with individuals' emotional maturity, leading to more stable marriages, responsible family planning, and equitable relationships. It also influences the age structure and growth rate of populations, playing a role in economic development and resource allocation.

The impact of an appropriate age at marriage on population management is significant. Individuals who marry at a more mature age, typically in their twenties, are likely to contribute to better population management through more responsible family planning and reproductive health choices. Setting a higher marital age aligns with the emotional and psychological maturity of individuals, which tends to stabilize around age 25-26, reducing rates of marital dissolution. Additionally, higher marital ages can lead to a more equitable relationship between spouses and better investment in children's education and well-being. When couples marry later in life, they are often better equipped economically and emotionally, which influences their decisions on the number and spacing of children, contributing to an optimized population growth rate.

On the societal front, the age at which people marry can have implications for the age structure of a population, which is associated with economic development and population momentum. In countries with a younger age structure, a later average age at marriage can help slow down population growth, allowing for better allocation of resources such as water and education. Overall, promoting an appropriate marriage age is critical for both individual well-being and broader societal benefits, including managing population trends and fostering economic development.

In the last few decades, demand for ketchup has dropped in the United States, while demand for salsa has risen. Which factors that affect demand account for this?

Answers

Substitutes, and also perhaps consumer tastes, account for this change in demand for ketchup and for salsa.

The rise in demand for salsa and drop in demand for ketchup in the United States can be attributed to factors like changing tastes, prices of related goods, and shifts in population demographics.

Changing Tastes or Preferences: As people's preferences for different flavors and cuisines evolve, they shift their demand towards products like salsa.

Changes in the Prices of Related Goods: If the prices of substitutes like salsa decrease or become more appealing, the demand for ketchup may decline.

Changes in the Composition of the population: Demographic shifts can also influence demand trends, affecting the popularity of certain products over others.
