Answer:

its B) Thermohaline currents  Sorry if its wrong but im sure this could be it

Explanation:These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.

Thermohaline currents deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses

Thermohaline currents is also known as 'the ocean conveyor belt' or 'the global conveyor belt'. It is a part of the large scale ocean circulations.

As the name thermohaline suggested that, 'thermo' means heat and 'haline' refers to the salt content. So, when there is a great difference in the temperature and the salt content deep sea currents occur.

Hence option (2) is correct i.e. thermohaline currents occur due to temperature and salinity difference.

Answer:

Multiply the length value by 6.68456e-9

Explanation:

The question involves converting from one unit (kilometers) to another unit (Au)

From the question;

149,598,000 km = 1 AU

1 km = x

Cross multiplying;

1  * 1 = x * 149,598,000

1 = 149,598,000x

x = 1 / 149,598,000

x = 6.68456e-9

To convert kilometer to Au; Multiply the length value by 6.68456e-9

Answer: 59.41

Explanation:

The final temperature of the system has been 130[tex]\rm ^\circ C[/tex].

Specific heat can be defined as the amount of heat required to raise the temperature of 1 g of substance by 1-degree celsius.

The amount of heat lost and the heat gained have been equal.

Heat = mass × specific heat × change in temperature

Thus,

mc[tex]\Delta[/tex]T = mc[tex]\Delta[/tex]T

50 g × (10 - x) = 120 × (x - 80)

500 - 50x = 120x - 9600

70x = 9100

x = 130

Thus, the final temperature of the system has been 130[tex]\rm ^\circ C[/tex].

Mass of a substance = Moles of a substance × molar mass of a substance

We have 0.94 moles of NaHCO3. The molar mass of NaHCO3 is the sum of the atomic masses of the elements comprising NaHCO3, which is approximately 84.007 g/mol.

The mass of 0.94 moles of sodium bicarbonate is therefore (0.94 moles NaHCO3)(84.007 g NaHCO3/mol NaHCO3) = 78.97 ≈ 79 grams of sodium bicarbonate.

Then we convert 0.30 moles of aluminum into moles of aluminum oxide, using the stoichiometric coefficients:

Finally we convert 0.15 moles of Al₂O₃ into grams, using its molar mass:

Answer:

0.0125mol

Explanation:

Molarity (M) = number of moles (n) ÷ volume (V)

n = Molarity × Volume

According to this question, a 0.05M solution contains 250 mL of NaOH. The volume in litres is as follows:

1000mL = 1L

250mL = 250/1000

= 0.250L

n = 0.05 × 0.250

n = 0.0125

The number of moles of NaOH is 0.0125mol.

Answer:A) H20 gas

Explanation:

Based on the property of gases, 1-gram sample of hydrogen gas, H₂ in a sealed 1-liter container will occupy the container completely and uniformly.

Gases are one of the states of matter.

Gas molecules have negligible forces of attraction between them, therefore, they are always in motion.

Gases do not have a specific shape or volume, rather they fill up every available space in their container.

Of the given option, only H₂ is a gas.

Therefore,  1-gram sample of hydrogen gas, H₂ in a sealed 1-liter container will occupy the container completely and uniformly.

Answer:

n = 2 moles (1 sig-fig)

Explanation:

Using the Ideal Gas Law equation (PV = nRT), solve for n (= moles) and substitute data for ...

pressure = P(atm) = 100atm

volume =V(liters) = 50L

gas constant = R = 0.08206L·atm/mol·K

temperature = T(Kelvin) = °C + 273 = (35 + 273)K = 308K

PV = nRT => n = PV/RT = (100atm)(50L)/(0.08206L·atm/mol·K)(308K)

∴ n(moles) = 1.978moles ≅ 2 moles gas (1 sig-fig) per volume data (= 50L) that has only 1 sig-fig. (Rule => for multiplication & division computations round final answer to the measured data having the least number of sig-figs).

Moles are the ratio of the mass and the molar mass of the substance. In a 50.0 L cylinder, 2 moles of gas are present at 100 atm and 35 degrees celsius.

An ideal gas equation states the relationship between the moles of the substance, temperature, pressure, and volume. The ideal gas equation is given as,

[tex]\rm PV = nRT[/tex]

Given,

The pressure of the gas (P) = 100.0 atm

Volume of the gas (V) = 50.0 L

Temperature (T) = 308 K

Gas constant (R) =  0.08206 L atm/mol K

Substituting values in equation moles (n) is calculated as:

[tex]\begin{aligned} \rm n&= \rm \dfrac{PV}{RT}\\\\&= \dfrac{100 \times 50}{0.08206 \times 308}\\\\&= 1.978\end{aligned}[/tex]

Therefore, 1.978 or 2 moles of gas are present.
