Answer:
Disrupted food webs
increased competition
disrupted life-cycle events
forced relocation
Explanation:
Global warming refers to a gradual rise in the temperature of the earth due to the increase in the concentration of greenhouse gases in the atmosphere which trap infrared radiation close to the earth.
This gradual increase in the temperature of the earth often have devastating effects on the lives of various organisms on earth. These effects include;
Disrupted food webs
increased competition
disrupted life-cycle events
forced relocation
Due to changes that occur in the ecosystem as a result of global warming, many species may be compelled to relocate from place to place. This in turn disrupts food webs and may lead to disruption of life cycle events of the concerned organisms. Decrease in the number of certain populations due to global warming may lead to increased competition among species for food.

How much energy required to raise the temperature of lead by the same degrees.
Answer:
If a one kilogram block of lead absorbs 2,000 J of energy then the temperature rise will be larger. If 1,000 J of heat is absorbed by a 2 kg block of lead then the temperature of the block doesn't rise as much since the energy is shared between more particles.

Add more drink mix until you notice a color change. Have you increased or decreased the concentration? (Higher number means a higher concentration).
Answer:
Increased the concentration
Explanation:
Complete Question
Open the simulation by pushing the play button. Begin by dragging the concentration tester overto the liquid and add drink mix until the concentration reaches approximately 2.oo mol/L. This means there are 2.00 moles of the drink mix in 1 Liter of the solution. Add more drink mix until you notice a color change. Have you increased or decreased the concentration? (Higher number means a higher concentration).
Solution
Drink mix is basically the solute which is added to solvent i.e water.
The higher is the amount of drink mix in the solvent, the higher is the concentration of the solute and hence darker is the color of the drink.
Hence, in the case the concentration of the drink has been increased.
If your end product is 1.5 moles of KMnO4, how many moles of manganese oxide were used in the reaction?
The equation for the production of potassium permanganate is as follows:
2 MnO2 + 4 KOH + O2 → 2 KMnO4 + 2 KOH + H2
You must show all work
Answer:
1.5 moles of KMnO4 will be produced from 1.5 moles of MnO2
Explanation:
The balanced equation of this chemical reaction is
2 MnO2 + 4 KOH + O2 → 2 KMnO4 + 2 KOH + H2
2 moles of MnO2 produces 2 moles of KMnO4
That means 1 moles of KMnO4 will be produced from 1 moles of MnO2
Hence, 1.5 moles of KMnO4 will be produced from 1.5 moles of MnO2
The moles of manganese oxide were used in the reaction is 1.5 moles.
What is stoichiometry?Stoichiometry of any reaction tells about the relative amount of species present before and after the chemical reaction.
Given chemical reaction is:
2MnO₂ + 4KOH + O₂ → 2KMnO₄ + 2KOH + H₂
From the stoichiometry of the reaction, it is clear that same moles of manganese oxide and potassium permanganate is involved in the reaction.
2 moles of KMnO₄ = produce by 2 moles of MnO₂
1.5 moles of KMnO₄ = produce by 2/2×1.5=1.5 moles of MnO₂
Hence, required moles are 1.5 moles.

Global climate change is a result of human activity?
Answer:
Yes
Explanation:
Due to pollution, greenhouse gasses, etc
Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.

What is the rate of diffusion of NO gas to CO gas?
Answer:
0.97
Explanation:
Let R₁ represent the rate of diffusion of NO.
Let R₂ represent the rate of diffusion of CO.
Molar mass of NO (M₁) = 14 + 16 = 30 g/mol
Molar mass of CO (M₂) = 12 + 16 = 28 g/mol
Thus, the rate of NO to CO can be obtained as follow:
R₁ /R₂ = √(M₂/M₁)
R₁ /R₂ = √(28/30)
R₁ /R₂ = √(28/30)
R₁ /R₂ = 0.97
R₁ : R₂ = 0.97
NO : CO = 0.97
Therefore, the rate of diffusion of NO to CO is 0.97
A sample of O2 with an initial temperature of 50.0 oC and a volume of 105 L is cooled to -25 oC. The new pressure is 105.4 kPa and the new volume is 55.0 L. What was the initial pressure of the sample? Show your work, using the G.U.E.S.S. method.
Answer:
71.92 kPa
Explanation:
Using the combined gas law equation;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (kPa)
P2 = final pressure (kPa)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question;
T1 = 50°C = 50 + 273 = 323K
V1 = 105L
T2 = -25°C = -25 + 273 = 248K
P2 = 105.4 kPa
P1 = ?
V2 = 55.0 L
Using P1V1/T1 = P2V2/T2
P1 × 105/323 = 105.4 × 55/248
105P1/323 = 5797/248
0.325P1 = 23.375
P1 = 23.375 ÷ 0.325
P1 = 71.92 kPa

What two metals are have atoms larger than that of sodium
Answer: potassium and rubidium
Explanation:
1) The group 1 of the periodic table contain six elements namely Lithium(Li), Sodium(Na),Potassium(K),Rubidium(Rb),Cesium(Cs) and Francium(Fr). These metals are called alkali metals because they form alkalies( i.e. strong bases capable of neutralizing acids) when they react with water.
2) The heavier alkali metals (K, Rb, and Cs) react so vigorously that they invariably explode.
3) This trend, which is not consistent with the relative magnitudes of the reduction potentials of the elements, serves as another example of the complex interplay of different forces and phenomena—in this case, kinetics and thermodynamics.

Answer:
Friendship is, in many respects, a "comfortable" love relationship. Friendships involve as little or as much intimacy as the partners are inclined to express at any given time. Friends are not normally obligated to exchange benefits, but do so in ways that are often so natural as to be unwitting. The ties that bind them are by unfettered mutual consent. In spite of its being so comfortable, in fact because of it, friendship contributes in unique ways .
