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.

Calculate the amount, in mol, of sodium atoms represented by 1.0x10(to the power of 20) sodium atoms
Explanation:
moles= number of particle or atom / 6.02×10^23
so
[tex] \frac{1.1 \times {10}^{20 } }{6.02 \times {10}^{23} } [/tex]
gives u 1.83×10^-4 moles
hope it make sense :)
Answer:
1.7 * 10^-4 moles
Explanation:
According to Avogadro, one mole of a substance contains 6.02 * 10^23 number of atoms, molecules, ions etc.
Hence;
1 mole of Na contains 6.02 * 10^23 atoms
x moles of Na contains 1.0x10^20 atoms
x = 1.0x10^20 * 1/6.02 * 10^23
x = 1.7 * 10^-4 moles
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.
Find the moles of 127.5g of NaCl.
Answer:
n = 2.18 moles
Explanation:
Given that,
Mass = 127.5g
Molar mass of NaCl = 58.44 g/mol
We need to find the number of moles. We know that,
No. of moles = Given mass/molar mass
Put all the values,
[tex]n=\dfrac{127.5\ g}{58.44\ g/mol}\\\\n=2.18\ moles[/tex]
Hence, there are 2.18 moles of 127.5g of NaCl.

conclusion on friendship
Explanation:
Conclusion. A good friendship is very difficult to come across. That is why we should appreciate this divine relationship that is based on understanding and feelings. ... A true friend is one of the most precious possessions that one can have in his life.Hope it's helpful for Yuh bro!!
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 .
If 2.18 grams of Br2 react with excess KI, how many grams of KBr are formed? Br2 + 2 K1 - 12 +2 KB
Answer:
2.18 grams of Br2 reacts to produce 3.25 grams of KBr
Explanation:
The balanced equation is
2 KI + Br2 → 2 KBr + I2
2 moles of KI and 1 mole of Br2 reacts to produce two molecules of KBr
Mass of two moles of KI = 2 * 166 grams
Mass of one mole of Br2 = 159.808 grams
Mass of two moles of KBr = 2* 119 grams
Thus, 159.808 grams of Br2 reacts to produce 2* 119 grams of KBr
2.18 grams of Br2 reacts to produce {(2* 119)/ 159.808} * 2.18 grams of KBr
2.18 grams of Br2 reacts to produce 3.25 grams of KBr
How many grams does 2.1
moles of SnF, weigh?
Answer:
289.8g
Explanation:
Using the formula as follows:
mole = mass/molar mass
Molar mass of SnF = 119 + 19
= 138g/mol
Using mole = mass/molar mass
2.1 = mass/138
mass = 2.1 × 138
mass = 289.8g

What is chemical equation?A chemical equation is a symbolic representation of a chemical reaction that shows the products, reactants, and direction of the reaction.
An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance.
A base is a chemical species that donates electrons, accepts protons, or releases hydroxide (OH-) ions in aqueous solution.
A salt, in chemistry, is defined as the product formed from the neutralisation reaction of acids and bases.
Therefore, in this chemical equation option D is true about the equation i.e
Ca(OH)2 is the base and CaCl2 is the salt.

Describe the sequence of adding ingredients to make the recipe for condensed tomato soup. To mix the ingredients, you have an industrial-sized vat with a capacity of 800 L. You also have the ability to heat what is in the vat and/or stir the vat, both of which require energy and therefore, cost you money. Focus on the fact that the manufacturing process should be time efficient and cost efficient in terms of energy use. Be sure to refer to the solubility charts or graphs that you find for salt and sugar during your research. Finally, presume that the tomato powder has low solubility which is not temperature dependent.
Part B
What changes could be made to optimize the manufacturing process?
Answer:
Part A:
"360 grams of NaCl can be dissolved in 1 L water. So, 2000 grams sugar can be dissolved in 1 L water then we can say that the solubility of salt is lesser in water as to sugar and both heightened by increasing the temperature. If we make a batch of 800 L we can add sugar, 1600 kg at 25 0c. We can add salt is 288 kg at 25 0c and the ingredient tomato is having low solubility."

CH4+xO2=CO2+2H2O. Find x
Answer:
x = 2, [tex]CH_{4} + 2O_{2} = CO_{2} + 2H_{2}O\\[/tex]
Explanation:
This question is related to balancing chemical equations.
[tex]CH_{4} + xO_{2} = CO_{2} + 2H_{2}O\\[/tex]
- There must be the same amount of carbons (C), hydrogens (H), and oxygens (O) on each side of the equals sign.
- There is already 1 carbon and 4 hydrogens on each side of the equals sign. The big number in front of the chemical compound multiplies into the individual elements and can be multiplied by the subscripts to get the total number of each element.
- On the right side of the equation, there are 4 oxygens (O), and on the left side, there are 2. In order for there to be 4 oxygens (O) on the left side, there must be a 2 in front of [tex]O_{2}[/tex].
Therefore, x = 2.
[tex]CH_{4} + 2O_{2} = CO_{2} + 2H_{2}O\\[/tex]

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.
