Answer:

Latitude is one of the main factors affecting temperature. Latitude is the measurement of the distance of a location on the Earth from the equator. ... At the Equator, the Sun's rays strike the Earth at a right angle, which makes the heat more intense and concentrated over a small area.

Explanation:

As latitude increases, the temperature falls, and vice versa. Generally, around the world, it gets warmer towards the equator and cooler towards the poles.

Answer:

(e) 1

Explanation:

Each atom has some energy levels and each energy level requires an electron to have certain amount of energy to reside in that energy level. Similarly, in order to excite the hydrogen atoms to a state n =6, its electrons must be provided a certain amount of energy that is constant. This energy is provided in form of photons. These photons have a constant wavelength as a result of constant energy. So, when these electrons go back to the ground state, they emit photons of same wavelength to release the energy they absorbed. Hence, only 1 wavelength is produced when atoms relax to their ground state from n = 6.

Therefore, the correct answer will be:

A compound made of two ions.

Explanation

A binary compound is a compound formed from two different elements. There may or may not be more than one of each element.

For a binary ionic compound, a metal will always be the first element in the formula, while a nonmetal will always be the second.

Hence, a binary ionic compound is a compound made of two ions.

The following statement is true of pure water at any temperature: pH = 7.0, [H3O+][OH–] = 1.0 x 10–14, [H3O+] = [OH–].

What is pure water? Pure water is water that is free of impurities such as minerals, salts, and other organic and inorganic chemicals. It contains no suspended solids, chemicals, microbes, or dissolved solids. It is transparent, colorless, odorless, and tasteless.What is pH? The pH scale is a way to express the acidity or alkalinity of a solution. A pH of 7 is considered neutral, while a pH of less than 7 is considered acidic and a pH of greater than 7 is considered basic or alkaline. The pH scale runs from 0 to 14, with 7 being neutral.What are the [H3O+] and [OH–] concentrations in water?The concentration of hydrogen ions (H3O+) and hydroxide ions (OH–) in pure water is 1.0 x 10–7 M at 25°C. The product of these two concentrations is equal to 1.0 x 10–14. As a result, the [H3O+] concentration in water is equal to the [OH–] concentration. Therefore, the [H3O+] and [OH–] concentrations in pure water are both 1.0 x 10–7 M.What is the significance of pure water's [H3O+][OH–] = 1.0 x 10–14?The product of [H3O+] and [OH–] is constant in pure water, indicating that the concentration of one ion is inversely proportional to the concentration of the other. This is due to the fact that pure water is neutral, with a pH of 7.0, and the concentrations of H3O+ and OH– are equivalent. Furthermore, this relationship indicates that as the concentration of one ion increases, the concentration of the other ion must decrease in order to maintain the constant product.

The density of carbon monoxide gas at 20°C and 98 kPa is 1.145 g/L.

The ideal gas law is PV = nRT

where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in kelvin.

To find the density of carbon monoxide gas at 20°C and 98 kPa, we can use the ideal gas law to find the number of moles of gas in 1 L of gas at these conditions and then divide the mass of 1 mole of gas by the number of moles to get the density.

First, we need to convert the temperature to kelvin:

20°C + 273.15 = 293.15 K

Rearranging the ideal gas law, we get:

n = PV/RT

We can assume that the volume is 1 L, so:

n = (98 kPa)(1 L) / [(0.0821 L·atm/mol·K)(293.15 K)] = 0.0413 mol

The molar mass of carbon monoxide is 28.01 g/mol, so the mass of 0.0413 mol is:

0.0413 mol x 28.01 g/mol = 1.152 g

Therefore, the density of carbon monoxide gas at 20°C and 98 kPa is:

1.152 g / 1 L = 1.145 g/L

What is density?

Density is a physical property of matter that relates to the amount of mass per unit of volume of a substance. It is typically expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

2.70 grammes of N₂ must dissolve in 30.5 litres of water at 25 degrees Celsius and 4.46 atm of pressure.

The solubility of N₂ in water depends on the temperature and pressure. To determine the volume of water needed to dissolve 2.70 grams of N₂ at 25 °C and 4.46 atm, we need to use the Henry's law equation, which relates the solubility of a gas in a liquid to its partial pressure:

C = kH x P

where C is the concentration of the gas in the liquid, kH is the Henry's law constant for the gas, and P is the partial pressure of the gas above the liquid.

The Henry's law constant for N₂ in water at 25 °C is 7.07 x 10⁻⁴ M/atm.

First, we need to convert the mass of N₂ to moles using its molar mass:

moles of N₂ = 2.70 g / 28.02 g/mol = 0.0963 moles

Next, we can use Henry's law equation to find the concentration of N₂ in water:

C = kH x P = (7.07 x 10⁻⁴ M/atm) x (4.46 atm) = 3.16 x 10⁻³ M

Finally, we can use the definition of concentration (C = moles of solute / volume of solvent) to solve for the volume of water needed:

Volume of water = moles of solute / concentration = 0.0963 moles / 3.16 x 10⁻³ M = 30.5 L

Therefore, 30.5 liters of water are needed to dissolve 2.70 grams of N₂ at 25 °C under a pressure of 4.46 atm.

The mass of water (H₂O) needed to meet the oxygen demand is 191587.5 g

2H₂ + O₂ —> 2H₂O

Molar mass of O₂ = 16 × 2 = 32 g/mol

Mass of  O₂ from the balanced equation = 1 × 32 = 32 g

Molar mass of H₂O = (2×1) + 16 = 18 g/mol

Mass of H₂O from the balanced equation = 2 × 18 = 36 g

SUMMARY

From the balanced equation above,

32 g of O₂ reacted to produce 36 g of H₂O

From the balanced equation above,

32 g of O₂ reacted to produce 36 g of H₂O

170300 g of O₂ will react to produce = (170300 × 36) / 32 = 191587.5 g of H₂O

The approximate pH of an acetate buffer with equimolar concentrations of acetic acid and sodium acetate is 5.

Let's understand this in detail:

What is a buffer solution?

A buffer solution is an aqueous solution that has the ability to maintain a constant pH level. The buffer's most significant property is the ability to resist changes in pH when small quantities of acids or bases are added.

The buffer solution comprises a weak acid and its conjugate base and a weak base and its conjugate acid.

The Henderson-Hasselbalch equation is used to calculate the pH of a buffer:

Henderson-Hasselbalch equation

pH = pKa + log [A-]/[HA]Where pKa is the acid dissociation constant,

[A-] is the concentration of the conjugate base, and [HA] is the weak acid concentration.

The pKa value for acetic acid is 4.76. Since the concentrations of acetic acid and sodium acetate are equimolar, their concentrations are identical. Therefore, the concentration of the conjugate base is the same as the concentration of the weak acid.

Using the Henderson-Hasselbalch equation,

pH = 4.76 + log [A-]/[HA]pH = 4.76 + log 1pH = 4.76 + 0pH = 4.76

Therefore, the approximate pH of an acetate buffer with equimolar concentrations of acetic acid and sodium acetate is 5.

Answer:

The speed of sound in air is 333.33 m/s

Explanation:

The parameters given are the time it takes for the sound to male it to the cliff and back = 30 times in 9 seconds

Distance to the cliff = 50 meters

Therefore, the sound covers a distance of 30 × 100 = 3000 meters in 9 seconds

Which give the speed of sound in air using the formula for speed = Distance/Time

Therefore, the speed of sound in air = 3000/9 = 333.33 m/s.

We should add approximately 600 mg of magnesium sulfate to the one-liter IV solution to achieve the desired concentration.

The first step to convert mEq to milligrams is to know the atomic weight of magnesium, which is 24.3. To get 10 mEq of magnesium ion per liter, we need to add 1,203 milligrams of magnesium sulfate (10 x 24.3 x 2 x 1000 / 1) to a one liter IV solution. Therefore, the answer is 1,203 milligrams of magnesium sulfate should be added to the IV solution. Remember to always round to the nearest whole number in this case, so the answer would be 1,203. The MEW of MgSO₄ is its molecular weight (120) divided by the valence of Mg²⁺ (2). Thus, MEW = 120 / 2 = 60. Next, multiply the desired milliequivalents (10 mEq) by the MEW (60) to obtain the required amount in milligrams: 10 mEq x 60 mg/mEq = 600 mg. Therefore, you should add approximately 600 mg of magnesium sulfate to the one-liter IV solution to achieve the desired concentration.
