Lack of employment and income opportunities are pushing large contingents of people to frontier areas and new economic activities, such as gold mining, in the Amazonian region. The number of independent gold miners exceeded 200,000 by 1990. The mining process generates very dangerous and poisonous mercury pollution (mercury is used to separate the gold from other materials), and destroys aquatic and forest habitats. The local population whose diet depends on fish are now threatened by mercury poisoning, as are the miners themselves. –United Nations Research Institute for Social Development Read the text, then use the drop-down menus to complete the statements.

Theo mixes cake batter and places it in the oven at 350°F for 45 minutes. Explain what type of reaction baking a cake represents in terms of energy
Answer:
Baking a cake requires heat to be applied to the batter in order for it to cook and chemically change into cake. The energy or heat applied is absorbed by the ingredients, so this represents an endothermic reaction.

What is true of the orbitals in the 3d energy level?
A. They have higher energy than 2s orbitals.
B. They have lower energy than 4f orbitals.
C. Together, the five 3d orbitals can hold 10 electrons.
D. All of the above are true.
Answer:
D. All of the above are true.
Explanation:
All the given options in the problem are true.
According to Aufbau's principle, the sublevels with lower energy are filled before those with higher energies.
The order of filling according to their energies is;
1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p
We see that the 3d energy level is lower than 4f but higher than 2s.
Also, the 3d orbital has 5 subshells and each can hold a maximum of two electrons.
This gives a capacity of 10 electrons.

Please Help. A car was sitting in sunlight all day long.The heat that is now contained in the car was transferred to the car primarily by which of the following processes?
A. Radiation
B. Conduction
C. Convection
D. Electrical energy transfer
Answer: A
Explanation:
The heat contained in the car was transferred to the car primarily by the process of radiation.
Radiation is the emission of electromagnetic wave energy that originates from a source and travels via a space medium with the speed of light. When it is sunny during the day, all life forms and inanimate objects are exposed to radiation. Since a car has metallic properties, it has the ability to store and contain the heat for a longer period of time through the process known as radiation.

determine the specific heat ofmaterial if a 12g sample absorbed 48j as it was heated from 20-40
Answer:
c =0.2 J/g.°C
Explanation:
Given data:
Specific heat of material = ?
Mass of sample = 12 g
Heat absorbed = 48 J
Initial temperature = 20°C
Final temperature = 40°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 40°C -20°C
ΔT = 20°C
48 J = 12 g×c×20°C
48 J =240 g.°C×c
c = 48 J/240 g.°C
c =0.2 J/g.°C
Purple flowers are dominant over white flowers. The parent generation includes two heterozygous parents. What are the possible phenotypes of these parents’ offspring? 3 purple and 1 white 3 white and 1 purple 1 purple, 2 lilac, and 1 white 1 white, 2 speckled, 1 purple
A. 3 purple and 1 white. :)
answer on EDGE2020. took/taking the exam.
Purple flowers are dominant over white flowers. The parent generation includes two heterozygous parents. The possible phenotypes of these parents’ offspring are 3 purple and 1 white. Therefore, option A is correct.
What do you mean by phenotype ?A person's genotype is their unique DNA sequence. This term is used to refer to the two alleles that a person inherited for a specific gene. A patient's clinical presentation is the detectable expression of this genotype.
We have three phenotypic classes with one locus and additive effects: AA, Aa, and aa.
Height, wing length, and hair color are all phenotypes. Phenotypes also include observable characteristics that can be measured in the lab, such as hormone levels or blood cell counts.
Purple flowers outnumber white flowers. There are two heterozygous parents in the parent generation. These parents' offspring could have three purple phenotypes and one white phenotype.
Thus, option A is correct.

The normal boiling point of mercury (Hg) is 356.7 °C. What is the vapor pressure of mercury at 333 °C in atm? (∆Hvap = 58.51 kJ/mol
Answer:
Here you can use the Clausis Clayperon equation: ln P1/P2=-Ea/R-(1/T1 - 1/T2)
where P1 is the pressure at standard condition: 760 mm Hg
P2 is the variable we need to solve
Ea is the activation energy, which in this case is delta H vaporisation: 56.9 kJ/mol
R is the gas constant 8.314 J/mol or 8.314 J/mol /1000 to convert to kJ
T1 is the normal boiling point 356.7 C, but converted to Kelvin: 629.85K
T2 is room temperature 25 C, but converted to Kelvin: 298.15 K
Once you plug everything in, you should get 4.29*10^-3 mmHg

If metal X is lower than metal Y on the activity series, then:
A. X will react in water, but only if the temperature is low enough
B. Y will form oxides of X, but only indirectly
C. X will replace ions of Y in a solution
D. Y will replace ions of X in a solution
Answer:
D. Y will replace ions of X in a solution
Explanation:
If metal X is lower than metal Y on the activity series, then Y will replace ions of X in a solution.
This is the crux of single displacement reactions.
In a single displacement reaction, a metallic ion in solution is replaced by a metal higher in the activity series than the metal in solution. On the activity series, metals higher are more reactive and will displace the lower and less reactive ones. Reactivity increases up the group.a b c or d? help asap
