Explanation:

Answer:

The correct answer is - potassium.

Explanation:

Electron configuration is the representation of the distribution or arrangement of electrons in orbital shells and subshells of a particular atom. IN this question the given electron configuration is -

1s^22s^22p^63s^23p^64s^1

By the configuration, it is clear that it belongs to

- the s group as the last electron is n s orbital and

- only 1 electron which means it belongs to group 1 in the periodic table

- last orbital is 4 so it is from the 4th period

- total electron = 19

Thus, the correct answer is - Potassium or K.

Answer:

Sun.

Explanation:

Weather can be defined as the atmospheric conditions of a particular area over a short period of time.

The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

Humidity refers to the concentration (amount) of water vapor that is present in the air. It is high when there's a lot of water vapor in the air and low when the level of water vapor is small.

Additionally, at constant humidity, relative humidity is inversely proportional to temperature i.e as the temperature decreases, relative humidity increases.

In this scenario, an area has a few days of low humidity, warm air temperature, and high air pressure. Thus, the kind of weather this area is experiencing is a sun i.e a sunny weather in which the air temperature is warm while having a high atmospheric pressure and low humidity.

Formation. Wave shoaling is the process when surface waves move towards shallow water, such as a beach, they slow down, their wave height increases and the distance between waves decreases. This behavior is called shoaling, and the waves are said to shoal.

Heavy rain fall causes shoals to form and change shape creating depressions and bars in the sand

Heavy rain fall most commonly causes shoals to form or change shape making depressions and bars in the sand.

What causes a shoal ?

Wave shoaling occurs when surface waves slow down, their wave height rises, and the space between waves narrows as they approach shallow water, like a beach. The waves are said to shoal because of this action, which is known as shoaling.

The shoal, a buildup of silt that might be hazardous to ships in a river channel or on a continental shelf.

Conventionally, it is assumed that the continental shelf is less than 10 metres below sea level at low tide. Shoals are created mostly by the same processes that result in offshore bars.

Thus, Heavy rain fall causes shoals to produce and change shape creating depressions and bars in the sand.

Answer:

0.52 mol

Explanation:

Using the general gas equation formula:

PV = nRT

Where;

P = pressure (atm)

V = volume (Liters)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

At STP (standard temperature and pressure), temperature of a gas is 273K, while its pressure is 1 atm

Using PV = nRT

n = PV/RT

n = (1 × 11.74) ÷ (0.0821 × 273)

n = 11.74 ÷ 22.41

n = 0.52 mol

There are 0.52 moles in the basketball

Answer:

21091mg of aspirin the person need to consume

Explanation:

To solve this question we must find the mass of the person in kg. Knowing the lethal dose for aspirin is 400mg/kg of person, we can find the amount of aspirin that the person need to consume to get a lethal dose:

Mass person:

116lb * (1kg / 2.2lb) = 52.7kg

Lethal dose:

52.7kg * (400mg / kg) =

21091mg of aspirin the person need to consume

Answer:

119.98 mL

Explanation:

Initial volume V1 = 123 ml

Initial temperature = T1 = 21◦C + 273 = 294 K

Initial pressure P1 = 760 Torr - 18.65 Torr = 741.35 Torr

Final volume V2= ???

Final temperature = T2= 21◦C + 273 = 294 K

Final pressure P2 = 760 Torr

From;

P1V1/T1= P2V2/T2

P1V1T2 = P2V2T1

V2 = P1V1T2/P2T1

V2= 741.35 * 123 * 294/760 * 294

V2 = 119.98 mL

Alkaneshave thegeneral formulaof CnH2n+2where n is the number of carbon atoms.

Answer:

0.482 g of N₂O are produced.

Explanation:

The reaction is: 2N₂ + O₂ → 2N₂O

In order to produce 2 moles of N₂O, we need to make react 1 mol of oxygen and 2 moles of nitrogen.

We determine the moles of each reactant:

7.45 g / 28g/mol = 0.266 moles of nitrogen

36.5 mL . 0.15 M = 5.475 mmoles → . 1mol /1000 mmol = 0.00547 moles

Certainly the oxygen is the limiting reactant.

In order to determine the grams produced, we need to know the limiting reactant.

2 moles of N₂ need 1 mol of O₂

Then 0.266 moles of N₂ may react to (0.266 . 1) /2 = 0.133 moles

We only have 0.00547 moles, so there is not enough O₂.

1 mol of O₂ can produce 2 moles of N₂O

Then, the 0.00547 will produce (0.00547 . 2) /1 = 0.01095 moles

We convert to mass: 0.01095 mol . 44 g /mol = 0.482 g

That's the answer.

Sand is a common material found on beaches, deserts, stream banks, and other landscapes worldwide. In the mind of most people, sand is a white or tan, fine-grained, granular material. However, sand is much more diverse - even beyond the pink sand beaches of Bermuda or the black sand beaches of Hawaii.

Answer:

Platelets are tiny blood cells that help your body form clots to stop bleeding.

Explanation:

If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.

[tex]\huge{\mathbb{\tt {ANSWER↓}}}[/tex]

Platelets are only about 20% of the diameter of red blood cells. The normal platelet count is 150,000-350,000 per microliter of blood, but since platelets are so small, they make up just a tiny fraction of the blood volume. The principal function of platelets is to prevent bleeding.

Answer:

The functional group is called an amide. This is option C.

Explanation:

We see this is a three-carbon chain (a propyl chain), that ends with a double bond to oxygen and a single bond to an amine group (NH2). If the end carbon were only bound to the NH2 group and 2 hydrogen atoms, it would be an amine. If the end carbon only had a double bond to oxygen and a single bond to hydrogen, it would be an aldehyde. However, when a terminal carbon (a carbon at the end of a chain) has both a double bond to oxygen, and a single bond to an amine (NH2), it is called an amide.

We can also discount the answer thiol right away because those have a carbon-sulfur bond, and there is no sulfur in this molecule.

Some of the glucose required for cellular respiration in humans is obtained by external food source which are rich in carbohydrates.

What is cellular respiration?

Cellular respiration is the process in which cells combines the oxygen with the foodstuff molecules, and converting the chemical energy into life sustaining activities as energy.

In the human body, we get the glucose for the cellular respiration from the external food source which are riched in carbohydrates, starch, etc. After converting the chemical energy to glucose then oxygen is absorbed in the lungs and circulate the blood through out the body by red blood cells.

Hence, we get glucose from food source.
