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
What is thermohaline currents?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:
it is the moisture in the air
Explanation:
if we buy a dehumidephire we see that it collets water from the air
Answer:
Humidity describes the amount of water vapor or water molecules in the air. Weather scientists use the term “relative humidity,” which Joe Sobel, a meteorologist and senior vice president at Accuweather described as “a comparison of the amount of moisture in the air versus the amount of moisture the air could hold.”

Why is Newton's first law of motion is sometimes called the law of inertia
Answer:
The reason why Newtons first law of motion is sometimes called the law of inertia is because it states that if the object is in motion, it will not rest unless an unbalanced force acts on the object.
2NO+2CO N 2 +2CO 2 There are 3.0 g of NO and 3.0 g of CO reacting . What is the limiting reactant ?
Answer: NO
Explanation:
As per the given balanced equation, 2 moles of NO reacts with 2 moles of CO. Hence, 3 g or 1.07 moles of CO needs to react with the same number of moles of NO. But we have only 3 g or 0.1 mole of NO. Hence, NO is the limiting reactant.
What is limiting reactant ?A limiting reactant in a reaction is the reactant which is fewer in amount or consume early without complete reaction with other reactants. Hence, as soon as this reactant is consume, the reaction stops.
Given 2 moles of NO reacts with 2 moles of CO.
molar mass of NO = 30 g/mol
molar mass of CO = 28 g/mol.
Number of moles in 3 g of CO = 3/28 = 1.07 moles
number of moles in 3 g of NO = 3/30 = 0.1 moles.
1.07 moles of CO needs 1.07 moles of NO. But only 0.1 moles are present.
Therefore, NO is the limiting reactant in this reaction.

Why is fluorine a gas at room temperature?
GIVING BRAINLIEST AND LOTS OF POINTS ‼️‼️
Answer:
In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.

If ONE mole of rocket fuel, ammonium perchlorate, NH4ClO4, is allowed to react with excess Al so that all of the NH4ClO4 is consumed, how many molecules of water will be produced? (All reactants & products are present in a 1:1 ratio.)
Answer:
9.03×10²³ molecules of H₂O
Explanation:
To solve this, we need to propose the reaction
NH₄ClO₄ → ammonium perchlorate
Al → Aluminum
Those are the reactants; the reaction is:
6NH₄ClO₄ + 10Al → 5Al₂O₃ + 3N₂ + 6HCl + 9H₂O
Then, water is one of the products. If we see the reaction, is a redox type.
Ratio is 6:9. In conclussion:
6 moles of ammonium perchlorate can produce 9 moles of H₂O
Then 1 mol of salt, may produce (1 . 9)/6 = 1.5 moles of water
Let's count the molecules:
1.5 mol . 6.02×10²³ molecules /mol = 9.03×10²³ molecules of H₂O

How many liters of bromine gas would 12.3 moles occupy at Standard Temperature and Pressure?
a.) 1 mole/22.4 L
b.) 22.4 mol/1 liter
c.) 22.4 L/1 mole
d.) 1 liter/22.4 mol
Answer:
c.) 22.4 L/1 mole
Explanation:
Using the general gas law equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
The standard values for a gas are as follows:
Standard pressure of a gas = 1 atm
Standard temperature of a gas = 273K
According to the information in the question, n = 12.3 moles
Using PV = nRT
V = nRT/P
V = 12.3 × 0.0821 × 273/1
V = 275.68 L
Based on this value of volume in liters for 12.3moles of Br gas, the volume per mole at standard temperature and pressure will be 275.68/12.3 = 22.4 Litres per mole. Hence, the answer is 22.4 L/1 mole.
A seedling is planted in soil that does not have any clay. What will most likely happen to the plant?
Answer:
Explanation:
Under good conditions the seedling can thrive in soil that does not have any clay as long as it gets the proper nutrients and right amount of sunlight/water that it needs. Clay in soil can provide the nutrients necessary for seedlings to thrive but can also cause many negatives. One such con of using clay is that it does not absorbe water very well, this ultimately causes the soil to become waterlogged and drowns the plants as no oxygen can pass through. This would ultimately kill the plants.
Lithium forms ions with a charge of lt Oxygen forms ions with a charge of 2- in the ionic compound lithium oxide, how many
atoms of lithium will there be if there is 1 atom of oxygen?
HELP ME
Answer:
There are 2 lithium atoms in the ionic compound lithium oxide, Li₂O
Explanation:
The charge of ions formed by lithium = 1⁺
The charge of ions formed by oxygen = 2⁻
In the ionic compound lithium oxide having 1 atom of oxygen, we have;
For the compound to be electronically neutral, the sum of the charges of the atoms in the ionic compound is zero
The charge of 1 atom of oxygen in the lithium oxide compound + The charge of the 'n' number of lithium atoms in the lithium oxide compound = 0
∴ 2⁻ + n × 1⁺ = 0
n × 1⁺ = 0 - 2⁻ = 2⁺
n = 2⁺/(1⁺) = 2
n = 2
The number of lithium atoms in the lithium oxide compound, n = 2
Therefore, there are two lithium atoms in the ionic lithium oxide (Li₂O) compound
The faster rate of reaction was caused by using a higher temperature. Explain, in terms of particles, why a higher temperature causes a faster rate of reaction.
Answer:
Increasing the temperature a reaction takes place at increases the rate of reaction. At higher temperatures, particles can collide more often and with more energy, which makes the reaction take place more quickly.

Example 1 How much water (in grams) is produced when 65.2 grams of Calcium carbonate react with phosphoric acid to form calcium phosphate, water, and carbon dioxide?
Answer:
11.75 g H2O
Explanation:
3CaCO3 + 2H3PO4 --> Ca3(PO4)2 + 3H2O + 3CO2
MM H2O = 18.02 g/mol
MM CaCO3 = 100 g/mol
? g H2O = mass CaCO3 x (1 mol CaCO3/MM CaCO3) x (3 moles H2O/3 moles CaCO3) x (MM H2O / 1 mol H2O) = (65.2/100) x 18.02 = 11.75 g H2O

Too many products can slow down the reaction
More reactants cause the reaction to heat up
More reactants have more atoms to react to form more products.
More reactants have more atoms to react to form more products in a chemical reaction.
What is a Chemical reaction?This is the process which involves two or more molecules known as reactants collide with the right orientation and force to form a new product.
Increase in reactants means presence of more molecules involved in the reaction thereby leading to the formation of more product.

Two grams of sodium chloride (table salt) were completely dissolved in a glass of water. How would you classify the resulting material?
Group of answer choices
As a mixture.
As a salt compound
As a pure substance
As an element
Answer:
This is a mixture.
Explanation:
While you can no longer see the salt when it's dissolved, it's still there! It's just in tiny, tiny, invisible to the eye molecules. It's now a mixture of H20 molecules and NaCl molecules in a solution :)
The water doesn't bond to the salt, so it's not a compound.
It's not just one element, it's a mixture of many!
It's not a pure substance since it's NaCl AND H2O.
