Whether a hydrogen-based energy system is environmentally cleaner than a fossil fuel system depends on ______.
Answers
Depending on the energy source utilized to manufacture the hydrogen, a hydrogen-based energy system may or may not be more ecologically friendly than a fossil fuel system.
Even when carbon capture and storage (CCS) is employed, hydrogen generated from fossil fuel feedstocks emits greenhouse gases (GHGs). In contrast, no GHG emissions are created when hydrogen is produced by electrolysis utilizing zero-emission power.
Hydrogen is a fuel that can be produced domestically and has nearly no potential for greenhouse gas emissions. When hydrogen is generated, a fuel cell is used to generate power; only hot air and water vapor are released as waste.
Currently, natural gas, a fossil fuel, is used to manufacture the majority of hydrogen. Hydrogen is now produced using both grid electricity and renewable energy sources including wind, solar, geothermal, or biomass.

In your own words, explain the motivation of slaves in the Civil War.
Answers
Answer:


On November 6, 1860 Abraham Lincoln was elected President of the United States -- an event that outraged southern states. The Republican party had run on an anti-slavery platform, and many southerners felt that there was no longer a place for them in the Union. On December 20, 1860, South Carolina seceded. By Febrary 1, 1861, six more states -- Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas -- had split from the Union. The seceded states created the Confederate States of America and elected Jefferson Davis, a Mississippi Senator, as their provisional president.
In his inaugural address, delivered on March 4, 1861, Lincoln proclaimed that it was his duty to maintain the Union. He also declared that he had no intention of ending slavery where it existed, or of repealing the Fugitive Slave Law -- a position that horrified African Americans and their white allies. Lincoln's statement, however, did not satisfy the Confederacy, and on April 12 they attacked Fort Sumter, a federal stronghold in Charleston, South Carolina. Federal troops returned the fire. The Civil War had begun.
Immediately following the attack, four more states -- Virginia, Arkansas, North Carolina, and Tennessee -- severed their ties with the Union. To retain the loyalty of the remaining border states -- Delaware, Maryland, Kentucky, and Missouri -- President Lincoln insisted that the war was not about slavery or black rights; it was a war to preserve the Union. His words were not simply aimed at the loyal southern states, however -- most white northerners were not interested in fighting to free slaves or in giving rights to black people. For this reason, the government turned away African American voluteers who rushed to enlist. Lincoln upheld the laws barring blacks from the army, proving to northern whites that their race privilege would not be threatened.
There was an exception, however. African Americans had been working aboard naval vessels for years, and there was no reason that they should continue. Black sailors were therefore accepted into the U.S. Navy from the beginning of the war. Still, many African Americans wanted to join the fighting and continued to put pressure on federal authorities. Even if Lincoln was not ready to admit it, blacks knew that this was a war against slavery. Some, however, rejected the idea of fighting to preserve a Union that had rejected them and which did not give them the rights of citizens.
The federal government had a harder time deciding what to do about escaping slaves. Because there was no consistent federal policy regarding fugitives, individual commanders made their own decisions. Some put them to work for the Union forces; others wanted to return them to their owners. Finally, on August 6, 1861, fugitive slaves were declared to be "contraband of war" if their labor had been used to aid the Confederacy in any way. And if found to be contraband, they were declared free.
As the northern army pushed southward, thousands of fugitives fled across Union lines. Neither the federal authorities

3 more GOP governors sending National Guard troops to US-Mexico border.Is this to protect us or to harm those new Americans who are about to join us?
Answers
The decision made by three GOP governors to send National Guard troops to the US-Mexico border can be viewed through different perspectives.
It is important to approach this issue with an understanding that political motivations can vary, and there may be a range of intentions behind such actions.
From one perspective, these governors may argue that sending National Guard troops is intended to protect the country.
Border security is a significant concern for many nations, including the United States.
Supporters of this decision might argue that deploying troops helps to enforce immigration laws, prevent unauthorized border crossings, and address potential security threats.
They may believe that a strong border presence is necessary to safeguard national interests, including public safety and economic stability.
On the other hand, some critics might express concerns that sending National Guard troops could potentially harm those seeking to immigrate to the United States.
They might argue that such actions can create an atmosphere of fear and hostility, particularly towards individuals fleeing from challenging situations in their home countries.
Critics may emphasize the importance of a humane and compassionate approach to immigration, suggesting that resources should be directed towards addressing the root causes of migration and establishing fair and efficient immigration processes.
It is essential to recognize that perspectives on this issue can vary significantly, influenced by differing values, political ideologies, and understandings of immigration and national security.

on spending for the next few months. He also says that you won't be taking your annual summer
family vacation. When you ask him what's going on, he tells you that he just filed his taxes and owes
a lot of money.
Is this a local, state, or federal issue?
Answers
Based on the information given, it sounds like a federal issue. Federal taxes are collected by the Internal Revenue Service (IRS) and owed by individuals and businesses to the federal government.
If the father owes a lot of money, it is likely related to his federal income tax liability. However, it is also possible that he owes state or local taxes in addition to his federal taxes, depending on where he lives and works. When individuals earn income in the United States, they are required to pay taxes on that income to both the federal government and their state of residence (if their state has an income tax). The federal government collects income taxes through the Internal Revenue Service (IRS), while state governments collect taxes through their respective departments of revenue or taxation. It's possible that the father in this scenario owes taxes at both the federal and state levels, but based on the information provided, it seems most likely that his financial troubles are related to his federal taxes. The father may have miscalculated how much he owed in taxes throughout the year, resulting in a large tax bill when he filed his tax return. Alternatively, he may have had a change in his financial situation, such as a new job or significant increase in income, that resulted in a higher tax liability.
