Describe wildfires. How is climate change impacting wildfires ?
Answer:
Hey mate.......
Explanation:
This is ur answer......
Climate change has been a key factor in increasing the risk and extent of wildfires in the Western United States. Research shows that changes in climate create warmer, drier conditions. Increased drought, and a longer fire season are boosting these increases in wildfire risk. But global warming has changed some of the underlying variables that make wildfires more or less likely to occur every year. Warmer temperatures increase the likelihood that fires will burn more intensely. They also cause snow to melt sooner, and lead to drier soils, forests, and plants, which act as kindling.

What is the molarity when 25.0 g of the compound NaClO3 is placed in 85.0 mL of solution?
Answer: Molarity when 25.0 g of the compound [tex]NaClO_{3}[/tex]is placed in 85.0 mL of solution is 294.12 M.
Explanation:
Given: Mass = 25.0 g
Volume = 85.0 mL (1 mL = 0.001 L) = 0.085 L
Molarity is the number of moles of a substance divided by volume in liter.
Hence, molarity of given solution is calculated as follows.
[tex]Molarity = \frac{mass}{Volume (in L)}[/tex]
Substitute the values into above formula as follows.
[tex]Molarity = \frac{mass}{volume (in L)}\\= \frac{25.0 g}{0.085 L}\\= 294.12 M[/tex]
Thus, we can conclude that molarity when 25.0 g of the compound [tex]NaClO_{3}[/tex]is placed in 85.0 mL of solution is 294.12 M.

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.

The chemical equation for zinc in hydrochloric acid is: Zn + HCI = ZnCl2 + H2
Does the above equation demonstrate the law of conservation of mass as it is currently written? Explain why or why not.
Answer: No it does not
Explanation:
The law of conservation of mass states that mass is neither created nor destroyed and in this equation you start with 1 molecule of Cl and 1 of H, but on the reactants side you end up with 2 of each. To make it follow the law of conservation of mass you would have to balance the equation
Para este mismo ejercicio, si se administran 2.5 litros de está solución (2,500ml) en un intervalo de 24 horas que cantidad en gramos de paciente en un día?
Answer:
Se administran 2500 gramos de solución por día.
Explanation:
Dado
Volumen de la solución = 2,5 litros
Como sabemos 1 litro = 1000 gramos
Por lo tanto, 2.5 litros = 2500 gramos
Se administran 2,5 litros en un intervalo de 24 horas o 1 día.
De ahí que se pueda decir que se administran 2500 gramos de solución al día.

Explain why for static electricity to occur between two surfaces that are rubbed against each other, one of the materials has to be an insulator
When two surface come in contact and rub each other a frictional force causing them s deformation and this leads to a voltage giving rise to a static charge.
What is static charge?Static charge is developed within a body temporarily with an induced polarization. These charges are not moving and set into a pole in the material.
When two materials rub against each other in which one is a conductor and other to be an insulator, they will attract by the induced polarization. Rubbing causes the free electrons in the condutor to be transferred towards the insulator.
This will cause a deformation that, the random charges in the material get polarized where the electrons in the insulator will repel to the opposite pol and positive charges will align in a pole close to the condutor.
This charge separation causes the positive pole of the insulator gets attracted into the conductor surface. Hence, there forms a static electricity by the passage of electron.

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
Which effects would many organisms likely experience if global warming occurs? Check all that apply.

increased competition
increased number of glaciers
disrupted life-cycle events
forced relocation
and any MHA fan to
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.

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.

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

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 .

When temperature drops, (for example from 20 degrees celsius to 10 degrees celsius)
a.) energy increases
b.) particles move slower
c.) particles collide more often
d.) pressure increases
Answer:
In the Celsius scale each degree is one part of 100 degrees. This is because in this scale the difference between boiling and freezing temperatures of water is 100 ° - 0 ° = 100 °, so one degree Celsius is one part of 100.
In the Farhenheit scale, each degree is one part of 180 degrees. This is because in this scale the difference between the boiling and freezing temperatures are 212 ° - 32 ° = 180°, so one degree Fahrenheti is one part of 180.
That means that 1 °C is a larger amount than 1 °C, so 20°C is a larger amount than 20°F.
Conclusion: 20 degree change represents a larger change in Celsius scale.
