Based on the duration and effect of the environmental change, the correct categorization is as follows:

  • Short-term changes - Fire, flood, pollution of waterways, disease
  • Long-term changes- extinction, early frost, deforestation, desertification

<h3>What are environmental changes?</h3>

Environmental changes refers to changes that occur in the environment either due to natural causes or by human activities.

Environmental changes can be categorized into:

  • short-term changes and
  • long-term changes

Short-term changes occur over a short period of time while long-term changes occur over a long period of time.

Based on the chart, the correct categorization is as follows:

  • Short-term changes - Fire, flood, pollution of waterways, disease
  • Long-term changes- extinction, early frost, deforestation, desertification

Therefore, both long-term and short-term changes occur in the environment.

Answer:

158.5g Zn are produced

Explanation:

To solve this question we have to find the moles of Aluminium. With the moles of Aluminium and the balanced reaction we can find the moles of Zn and its mass as follows:

<em>Moles Al -Molar mass: 26.98g/mol</em>

43.6g Al* (1mol/26.98g) = 1.616 moles Al

<em>Moles Zn:</em>

1.616 moles Al * (3mol Zn / 2mol Al) =

2.424 moles Zn are produced

<em>Mass Zn -Molar mass: 65.38g/mol-</em>

2.424 moles Zn * (65.38g / mol) =

<h3>158.5g Zn are produced</h3>

\The specific heat of aluminum is 0.21 cal g°C . How much heat is released when a 10 gram piece of aluminum foil is taken out of
DiKsa [7]

<u>Answer: </u>The amount of heat released is 84 calories.

<u>Explanation: </u>

The equation used to calculate the amount of heat released or absorbed, we use the equation:

Q= m\times c\times \Delta T

where,

Q = heat gained  or released = ? Cal

m = mass of the substance = 10g

c = specific heat of aluminium = 0.21 Cal/g ° C

Putting values in above equation, we get:

\Delta T={\text{Change in temperature}}=(10-50)^oC=-40^oC  

Q=10g\times 0.21Cal/g^oC\times-40^oC

Q = -84 Calories

Hence, the amount of heat released is 84 calories.
