What type of severe weather prevents sweat from evaporating to cool down bodies?

Answers

Answer 1

Answer:

hurricane/tropical cyclone

recurrent weather

The two types of downbursts are macrobursts and microbursts. A macroburst affects an area that's greater than 2.5 miles across. A microburst affects an area that's less than 2.5 miles across.

A funnel cloud forms as a spinning column of air that descends from a thundercloud. However, a funnel cloud doesn't become a tornado until it actually touches the ground. Once it touches the ground, where it begins to pick up dust and debris, it becomes a tornado.

Tropical cyclones, such as hurricanes, are fueled by warm ocean waters. Once they make landfall, they lose this fuel source and begin to lose strength.

The heat index and the wind chill index are similar because both consider other factors that affect how air temperature feels. The heat index considers relative humidity in relation to air temperature. Higher humidity makes air temperatures feel hotter. The wind chill index considers wind speed in relation to air temperature. Higher wind speeds make air temperatures feel colder.

Heat waves—Heat waves can be very dangerous when accompanied by high humidity. The human body depends on evaporation of sweat to cool itself down on hot days. When humidity levels are high, the rate of evaporation slows down. Consequently, it becomes harder for the body to cool itself and much easier for the body to overheat.

Which of the following is an example of commensalism?

Answers

Answer: A tick on a deer

Explanation:

because commensalism is a type of symbiotic relationship in which one species benefits, while the other species is neither harmed nor helped

please put brainlest for me if you found this helpful

An example of commensalism is tick on a deer. Therefore, option A is correct.

What is commensalism ?

Another sort of symbiotic interaction is commensalism, in which one organism benefits and the other does not in any way suffer. Golden jackals will pursue tigers as they hunt in order to consume the tigers' leftovers.

The term "commensalism" is derived from the word "commensal," which in human social interaction refers to "eating at the same table," and which itself is derived through French from the Medieval Latin term "commensalis," which refers to "sharing a table," from the prefix com-, which means "together," and mensa, which refers to "table" or "meal."

The simplest definition of commensalism is that it is a form of symbiosis in which one organism gains while the other neither gains nor suffers harm. The three primary forms of commensalism are phoresy, metabiosis, and inquilinism.

Thus, option A is correct.

List two possible steps where impurities may be gained, which would appear to be an increase in copper

yield (why you may get more than 100% of the copper back at the end). Be specific about the steps and

how they might add impurities.

Answers

Answer:

i) During washing

ii) During Measurement

Explanation:

The two possible steps are :

i) During washing : during the washing method the residue may be not completely dried out and this residue ( water) will add up to the final product ( copper yield ) and this kind of error is called human error.

ii) During measurement : If the weighing instrument is faulty there might be addition  in value of the final copper yield which will see the final yield value > 100% . this error occurs when the initial value and final value is  been weighed

How many moles are in 89 grams of KCI

Answers

Answer:

The number of moles in 89 grams of KCl is approximately 1.193 moles

Explanation:

A mole of an element or compound, is the quantity of the element or compound that contains 6.022 × 10²³ molecules of the element or compound, such that the molar mass of one mole is dependent on the mass of each molecule of the element or compound that make up the 6.022 × 10²³ particles

The given parameters are;

The mass of the KCl = 89 grams

The Molar mass, MW, of potassium, K = 39.1 g/mole

The Molar mass, MW, of chlorine, Cl = 35.5 g/mole

Therefore, given that KCl, has one K and one Cl, per mole, we have;

The Molar mass, MW, of potassium chloride, KCl = (39.1 + 35.5) g/mole = 74.6 g/mole

[tex]The \ number \ of \ moles, n=\dfrac{Mass}{Molar \ mass, MW}[/tex]

Therefore, the number of moles of KCl in 89 g, 'n' is given as follows;

n = (89 g)/(74.6 g/mole) ≈ 1.193 moles

The number of moles in 89 grams of KCl, n ≈ 1.193 moles.

What kind of pattern can you see about elements in the same period with respect to electron
structures?

Answers

Answer: A pattern of same atomic orbitals can be seen about elements in the same period with respect to electron structures.

Explanation:

The horizontal rows in a period table are called periods.

Elements present in the same period will have same atomic orbitals.

For example, electronic distribution of Na is 2, 8, 1 and it is a third period element.

Similarly, electronic distribution of Cl is 2, 8, 7 and it is also a third period element.

Hence, both Na and Cl will have K, L, M shells, that is, they have three atomic orbitals.

Thus, we can conclude that a pattern of same atomic orbitals can be seen about elements in the same period with respect to electron structures.

How many moles of NaOH are present in 22.0 mL of 0.140 M NaOH?

Answers

Answer:

Mole of NaOH = 0.00308 mole

Explanation:

From the question given above, the following data were obtained:

Volume = 22 mL

Molarity = 0.140 M

Mole of NaOH =?

Next, we shall convert 22 mL to L. This can be obtained as follow:

1000 mL = 1 L

Therefore,

22 mL = 22 mL × 1 L / 1000 mL

22 mL = 0.022 L

Finally, we shall determine the number of mole of NaOH in the solution. This can be obtained as shown below:

Volume = 0.022 L

Molarity = 0.140 M

Mole of NaOH =?

Molarity = mole / Volume

0.140 = Mole of NaOH / 0.022

Cross multiply

Mole of NaOH = 0.140 × 0.022

Mole of NaOH = 0.00308 mole

Thus, 0.00308 mole of NaOH is present in the solution.

Answers

Answer:

CH3OH(s)<CH3OH(l)<CH3OH(g)<CH3CH2OH(g)

Explanation:

Entropy is defined as the degree of disorderliness of a system. The more orderly a system is, the more its entropy tends to zero.

Hence solid particles have the least entropy because solid particles do not translate. The entropy of liquid particles is greater than that of solid particles since liquid particles can translate. Gas particles have the highest entropy because gas particles move at a very high velocity owing to minimal intermolecular interaction.

Also, the heavier the molecules of a substance, the larger its molar entropy therefore, CH3CH2OH(g) exhibits the greatest entropy.

Answers

Answer:

Weight = 500 Newton

Explanation:

Given the following data;

Acceleration due to gravity = 10N/Kg

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, the weight of an object is given by the formula;

[tex] Weight = mg [/tex]

Where;

m is the mass of the object.g is the acceleration due to gravity.

Note: In order to calculate the weight of a mass, it's required that the mass of an object or body is given.

However, in this particular question it was omitted in error and as such i would assume a value.

Let mass, m = 50 kg

Substituting into the formula, we have;

[tex] Weight = 50 * 10 [/tex]

Which is a property of all acids?

A. They increase the OH^- concentration in solution.
B. They contain OH^- ions.
C. They contain H3O^+ ions.
D. They increase the H^+ concentration in solution.​

Answers

D , for example HCl consists of H+ and Cl- ions

Acids increase the [tex]H^+[/tex] concentration in solution. Therefore, the correct option is D.

One of their essential characteristics is the ability of all acids to increase the concentration of H+ ions (protons) in a solution. Acids are chemicals that when dissolved in water add protons to the solution. As a result of this proton donation, the amount of [tex]H^+[/tex]ions in the solution increases, thereby lowering the pH. It is important to remember that not all acids contain[tex]H_3O^+[/tex] ions directly; Instead, [tex]H^+[/tex] ions can react with water molecules to generate [tex]H_3O^+[/tex] ions (hydronium ions).

Therefore, the correct option is D.
