aluminum metal reacts with aqueous copper (II) chloride to forma aluminum chloride & copper metal. how many grams of copper are needed to react an entire 35 gram sample of aluminum

Answers

Answer 1
Hi! The reaction is the following one:

2Al + 3CuCl₂ → 2AlCl₃ + 3Cu 

So if you want to know the grams of copper (II) chloride needed (you can't react the copper metal with aluminum metal. It should be the copper (II) chloride), you should use the following conversion factor, using the molar masses of the reagents:

[tex]35 g Al* \frac{1 mol Al}{26,98 g Al} * \frac{3 mol CuCl2}{2 mol Al} * \frac{134,45 g CuCl2}{1 mol CuCl2} = 261,62 g CuCl2[/tex]

So, the amount of CuCl₂ needed to react an entire 35-gram sample of aluminum would be 261,62 g CuCl2

Find the measure of angle C

Answers

We know that angles in a triangle sum to 180°, and are already given the measurement of a right angle. Therefore, we know that the other two missing angles add up to 180°-90°= 90°. So, we can place the given terms and this information into an equation and solve for x:
(3x+8)+(5x-14)=90
3x+8+5x-14=90
8x-6=90
8x=96
x=12
Measurement C is 3x+8, so just substitute x:
C=3(12)+8
C=36+8
C=44°

Which current issue in southwest Asia has its roots in ancient time?

Answers

I think it's c or d
Cuz those 2 are problems faced even today

The ongoing conflict between Israelis and Palestinians in the Middle East has its roots in ancient times. The correct option is A.

What is the region of Southwest Asia well known for?

Southwest Asia has the greatest known petroleum deposits in the world. Near and below the Persian Gulf is where the majority of them are gathered. More than half of the world's known oil is found in five nations that border the Persian Gulf: Saudi Arabia, Iran, Iraq, Kuwait, and the United Arab Emirates.

The conflict between Israelis and Palestinians over control of the land in the region dates back thousands of years, to when the land was inhabited by various groups of people, including the ancient Israelites, Philistines, and Canaanites.

The modern conflict can be traced back to the late 1800s and early 1900s when Jewish people began immigrating to the region in large numbers and seeking to establish a Jewish state.

This led to tensions with the Arab population, who also claimed the land as their own. Since then, the conflict has escalated and been marked by wars, violence, and diplomatic efforts to find a solution.

Thus, the ideal selection is option A.

Which are characteristics of the eye wall of a hurricane ? Check all that apply
A. Heaviest rains
B. Lighted rains
C. Strongest winds
D. Calmest air

Answers

(A) and (C) are the answers

Explaination :

The Eye Wall: a hurricane's most devastating region. Located just outside of the eye is the eye wall. This is the location within a hurricane where the most damaging winds and intense rainfall is found. The image below is of a hurricane (called cyclone in the Southern Hemisphere).

Final answer:

The eye wall of a hurricane is characterized by A. heaviest rains, C. strongest winds, and D. the calmest air in the storm.

Explanation:

The eye wall of a hurricane has several characteristics:

Heaviest rains: The eyewall is where you will naturally find the most intense rainfall in a hurricane. This is because the warm, moist air is forced upward, causing it to cool and condense into rain.Strongest winds: The eye wall is also where you will find the strongest winds in a hurricane. These winds can reach speeds of over 100 miles per hour and are responsible for the most destructive force of a hurricane.Calmest air: Contrary to popular belief, the eye wall is not where you will find calm conditions. The calmest air is actually found in the center of the hurricane, in an area called the eye.

In addition to this, just beyond the eye wall, the spiral rain bands extend outward with lower intensity thunderstorms and rain showers.

C. Storms and depressions
D. Average temperature

Answers

Answer:

Average temperature (D)

Explanation:

Global warming is the unusually rapid increase in Earth’s average surface temperature primarily due to the greenhouse gases released as people burn fossil fuels.

Final answer:

Global warming is the increase in average temperature around the Earth, which has been about 1°C over the past century. This rise is due to heightened greenhouse gas concentrations in the atmosphere, impacting various environmental factors and part of broader climate change.

Explanation:

Global warming is an increase in average temperature around the planet. Therefore, the correct answer to this question is D. Average temperature. Global warming refers to the recent and ongoing rise in global average temperature near Earth's surface, primarily caused by the escalation of greenhouse gases in the atmosphere. This rise in temperature over the past century has been around 1°C (about 1.3°F), which might seem small but has significant implications for the environment and species that are sensitive to climate changes. The phenomenon of global warming is a major aspect of climate change, which includes shifts in weather patterns, storm activity, wind patterns, and many other environmental factors.
