73 g of conc. hcl was diluted by adding 144g of water . how many gram atom of hydrogen are present in the dilute acid?​

Answers

Answer 1
Therefore, 18 gram atoms hydrogen are present in dilute acid. Hope this helps :)
Answer 2

The 73 g of concentrated Hydrochloric Acid was diluted by adding 144g of water. So, 18 grams atom of hydrogen are present in the dilute acid.

What is Hydrogen?

Methane, also known as natural gas, can be replaced with hydrogen, a clean fuel. It is the most prevalent chemical element and is thought to make about 75% of the universe's mass. Numerous hydrogen atoms can be found in water, plants, animals, and, of course, people here on earth.

Moles of HCl are -

n(HCl) = W(HCl) / M(HCl)

n(HCl) = 73/36.5

n(HCl) = 2 mol

Moles of H-atoms in HCl is -

n1 = 1 × 2

n1 = 2 mol

Moles of H2O are -

n(H2O) = W(H2O) / M(H2O)

n(H2O) = 144/18

n(H2O) = 8 mol

Moles of H-atoms in H2O is -

n1 = 2 × 8

n1 = 16 mol

Total moles of H-atoms is -

n = n1 + n2

n = 2 + 16

n = 18 mol

Therefore, 18-gram atoms hydrogen are present in dilute acid.

what would be the possible solution to Improve the situation that the tertiary sectors like Hospitals find themselves in because of load shedding .
Remember we are trying to solve the negative impact of load shedding?

Answers

Implementing backup power systems such as generators, utilizing renewable energy sources, and establishing efficient energy management strategies can help mitigate the impact of load shedding on hospitals.

To improve the situation for tertiary sectors like hospitals affected by load shedding, several possible solutions can be considered to mitigate the negative impacts:

1. Backup Power Systems: Hospitals should invest in reliable backup power systems, such as diesel generators or uninterruptible power supply (UPS) units. These systems can provide electricity during power outages, ensuring that critical medical equipment, life support systems, and lighting remain operational.

2. Smart Grid Infrastructure: Governments and utility companies should invest in smart grid infrastructure, which enables better monitoring and control of electricity distribution. This allows for more efficient load management and reduces the frequency and duration of power outages, minimizing the impact on hospitals and other critical sectors.

3. Prioritized Load Shedding: During load shedding, hospitals should be given priority to receive electricity, ensuring uninterrupted power supply to critical areas like emergency rooms, intensive care units, and operating theaters. This can be achieved through coordination between the power utility and healthcare authorities.

4. Renewable Energy Integration: Hospitals can explore integrating renewable energy sources like solar panels or wind turbines into their infrastructure. This helps reduce dependence on the grid and provides a more stable power supply, especially during load shedding.

5. Energy Storage Solutions: Implementing energy storage systems, such as batteries, can help hospitals store excess electricity during non-peak hours. This stored energy can be utilized during load-shedding periods to power essential equipment and maintain critical services.

6. Energy Efficiency Measures: Hospitals can adopt energy-efficient practices, including LED lighting, energy-saving appliances, and optimized HVAC systems. By reducing overall energy consumption, hospitals can better cope with the reduced availability of electricity during load shedding.

7. Collaborative Approach: Governments, utility companies, and healthcare institutions should collaborate to develop contingency plans, establish communication channels, and regularly review and update strategies to handle load shedding effectively.

Based on your answer, do you think this is a star that we might be able to send a space probe to? Why, or why not?

Answers

Yes I think is a star that we might be able to send a space probe to because the closest star to our solar system is Proxima Centauri, located about 4.24 light-years away. While it is the closest star, the distance is still immense.

To put it into perspective, if we were to travel at the fastest speed achieved by a human-made spacecraft (Voyager 1), it would take over 73,000 years to reach Proxima Centauri. Therefore, with our current technology, reaching even the nearest star within a human lifespan is not feasible.

However, it's important to note that space exploration and technology are constantly advancing. In the future, it's possible that new propulsion methods or revolutionary technologies could emerge, enabling us to contemplate interstellar missions. But as of now, sending a space probe to a distant star remains beyond our practical capabilities.

Answers

In the given scenario, the rock is most likely igneous in origin based on its coarse interlocking texture and visible crystals. It was found at location A and can be classified as an igneous rock.

To describe the characteristics of a rock that give clues about its origin, one needs to study the texture, mineralogy, and color of the rock. Based on these factors, one can decide whether the rock is igneous, sedimentary, or metamorphic in origin. A rock that is classified as igneous in origin typically has an interlocking texture of crystals that may be fine or coarse.

The color of an igneous rock is determined by the type of minerals that make up the rock. Some examples of igneous rocks include granite, basalt, and pumice.Sedimentary rocks are formed from the accumulation of sediment over time. They typically have a layered appearance and may contain fossils. The texture of a sedimentary rock depends on the size and shape of the sediment grains that make up the rock.

Examples of sedimentary rocks include sandstone, limestone, and shale. Metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure. They typically have a banded appearance and may contain minerals that are not present in the original rock. Examples of metamorphic rocks include marble, schist, and gneiss. In order to determine the origin of the rock in question, one must study its characteristics.

From the picture, it appears that the rock has a coarse interlocking texture with visible crystals. Based on these characteristics, the rock is most likely igneous in origin. From the surrounding landscape, it appears that the rock was found at location A. Therefore, this rock can be classified as an igneous rock that was found at location A.

One reason why a country might have a larger Jewish population was because during 1933 to 1941, Nazi Germany was on a rampage and evicted millions of Jewish families from their homes.

Many Jewish families were trying to immigrate to the U.S, but many didn't didn't get permitted to because the U.S had already taken in a lot of refugees and were worried about their national security and economy.
