Climate

Answer:

475.26°C

Explanation:

Given parameters:

Mass of object = 50g

Specific heat  = 0.3825J/g°C

Quantity of heat  = 4593Joules

Initial temperature  = 235.16°C

Unknown:

Final temperature = ?

Solution:

The quantity of heat absorbed by a body is a function of the mass, specific heat capacity and temperature change the body undergoes.

Mathematically, this relationship is given as;

              H  = m c Ф

where H is the quantity of heat

           m is the mass of the body

            c is the specific heat capacity

            Ф is the temperature difference

Ф  = final temperature - initial temperature

  Since we are solving for final temperature, let us substitute for other given parameters;

    H  =  m c ( final temperature - initial temperature)

       4593  = 50 x 0.3825 x (F  - 235.16)

       F - 235.16  = 240.1

             F  = 240.1 + 235.16 = 475.26°C

Answer: 0.0250

Explanation: 10 X 0.0750 = .75

.75 / 30 = 0.0250 M

The concentration of KOH(aq) solution is 0.025 M.

In this titration, the volume and concentration of HCl(aq) are given as 10.0 ml and 0.0750 M, respectively. The volume of KOH(aq) is given as 30.0 ml. To find the concentration of KOH(aq) solution, we can use the concept of stoichiometry and the balanced equation for the reaction:

HCl(aq) + KOH(aq) → H2O(l) + KCl(aq)

From the balanced equation, we can see that the ratio of moles of HCl to KOH is 1:1. Therefore, the moles of KOH can be calculated as:

moles of KOH = moles of HCl = volume of HCl × concentration of HCl

Substituting the values:

moles of KOH = 10.0 ml × 0.0750 M = 0.750 mol

The concentration of KOH(aq) solution can be calculated using the moles of KOH and the volume of KOH(aq) solution:

concentration of KOH = moles of KOH / volume of KOH(aq)

Substituting the values:

concentration of KOH = 0.750 mol / 30.0 ml = 0.025 M

There is an increase in the frequency of particle collisions which leads to the increased rate of the reaction.

Explanation:

Hydrochloric acid reacts faster with the powdered zinc than with the equal mass of zinc strips.  

Since the surface area of the Zinc particle increases when it is powdered and has more active spots when compared to less number of active sites in Zinc strips and so the number of collision between the Zinc particles and the particles of Hydrochloric acid also increases and consequently the rate of the reaction also enhances.

So there is an increase in the frequency of particle collisions.

Answer:

Climate change can affect coastal areas in a variety of ways

Explanation:

Final answer:

Global warming leads to sea level rise and extreme weather, threatening coastal communities with flooding, erosion, loss of habitat, and freshwater scarcity. Infrastructure must adapt, but preventive action, including reducing greenhouse gas emissions, is essential.

Explanation:

The negative impacts of global warming on coastal communities are profound and long-lasting. With current sea levels rising by approximately 0.25 meters, coastal cities face increased vulnerability to storm surges, which are exacerbated by high tides and heavy waves during storms. This not only threatens human structures but also contributes to the loss of biodiversity as ecosystems are disrupted. Furthermore, as the planet warms, polar ice caps and glaciers continue to melt, leading to a predicted rise in sea levels of two to four feet by 2100. This would result in widespread inundation of shorelines, reduction of island sizes, and possible disappearance of some islands. The alteration in the freeze-thaw cycle of the poles and glaciers may also lead to a lack of freshwater resources and an abundance of saltwater.

Changing patterns of precipitation due to climate change will require reconstruction of water management and food production infrastructures, with further impacts on ecosystems. The changing water flows can lead to the clearing of new areas for agriculture, road construction, and other developments, potentially impacting natural habitats and leading to a shift in biodiversity. Additionally, warming could introduce new economic activities in previously inaccessible Arctic regions, inevitably leading to further environmental degradation through infrastructure development.

The number of moles of aluminum sulfate produced from the 5.8 moles of aluminum hydroxide and excess sulfuric acid is 2.9 moles.

The balanced chemical equation can be given as:

2 Al(OH)₃ + 3 H₂SO₄ [tex]\rightarrow[/tex] Al₂(SO₄)₃ + 6 H₂O

In the above reaction, the stoichiometry of the amounts of each compound participating in the reaction is:

Al(OH)₃ - 2 moles

H₂SO₄ -  3 moles

Al₂(SO₄)₃ - 1 mole

H₂O - 6 moles

From the above observation, it can be assumed that for every 2 moles of aluminum hydroxide produce 1 mole of aluminum sulfate.

Then, the number of moles produced by 5.8 moles of aluminum hydroxide is x.

[tex]\text{moles of Al}_{2} (\text{SO}_{4} ){3} =\dfrac{\text{5.8moles of Al(OH)}_{3} \times \text {1 mole of Al}_{2} (\text {SO}_{4} ){3}}{\text {2moles of Al(OH)}_{3}}[/tex]

Explanation:

13.5 is the new concentration of this solution if it is boiled down to a

volume of 1.0 L.

Explanation:

Data given:

Initial volume of the solution of sea water = 2.5 litre

Molarity of NaCl solution M1 = 5.4 M

fInal volume = 1 litre

final molarity = ?

Assuming that no loss of NaCl from sea water took place when the sea water was boiled.

applying the formula for change in concentration as:

Minitial V initial = Mfinal X Vfinal

M final = [tex]\frac{M initial X V initial}{V final}[/tex]

Putting the values in the equation:

Mfinal = [tex]\frac{5.4 X 2.5}{1}[/tex]

M final = 13.5 M

thus it can be concluded that molarity will increase drastically when volume gets reduced from 2.5 litre to 1 litre. The solution becomes highly concentrated as water volume decreases due to evaporation.

The new concentration of a seawater solution initially at 5.4 M and 2.5 L volume, after boiling down to 1.0 L, is calculated to be 13.5 M using the principle of conservation of mass and the formula M1V1 = M2V2.

The question involves calculating the new concentration of a solution when its volume changes due to boiling. A 2.5 L sample of seawater with NaCl concentration of 5.4 M is reduced to 1.0 L after boiling. To find the new concentration, we use the principle of conservation of mass, which implies that the amount of solute (NaCl) remains constant even as the volume changes. Using the formula M1V1 = M2V2, where M1 and V1 are the initial concentration and volume, and M2 and V2 are the final concentration and volume, we can calculate the new concentration after boiling down to 1.0 L.

Initial information: M1 = 5.4 M, V1 = 2.5 L, V2 = 1.0 L.

Calculation: To find M2, rearrange the formula to M2 = (M1V1) / V2. Therefore, M2 = (5.4 M * 2.5 L) / 1.0 L = 13.5 M.

The new concentration of the NaCl solution after being boiled down to 1.0 L is 13.5 M. This demonstrates how the concentration of a solution increases as the volume decreases, provided no solute is added or removed.
