WILL GIVE BRAINLIEST (also pls don't copy answers from other ppl :D) Question: Choose two spheres of Earth which interact when hot springs are formed. Use complete sentences to explain how they interact during this process.
Answer:
Geosphere and Hydrosphere.
Explanation:
Hot springs are heated by geothermal heat—heat from the Earth's interior. In volcanic areas, water may come into contact with very hot rock heated by magma. The geosphere and hydrosphere interact when hot springs form. The geosphere gets a little melted by the hot hydrosphere and then when the springs shoot up in the air they break some rocks.

Calculate the emf of the following concentration cell: Au(s) | Au3+ (0.10 M) || Au3+ (0.50 M) | Au(s)
The emf of the cell as written is calculated to be 0.014 V.
Using the Nernst equation;
Ecell = E°cell - 0.0592/n log Q
We must note that E°cell = 0 because the anode and cathode are composed of the same type of metal.
Now;
Substituting values, we have;
Ecell = 0 - 0.0592/3 log (0.50 M)/(0.10 M)
Ecell = 0.014 V

Which event is an example of an exothermic reaction?(1 point)
A. Combustion
B. Evaporation
C. Decomposition
D.Melting ice
Answer:
Combustion
Explanation:
An exothermic reaction is defined as a reaction that releases heat and has a net negative standard enthalpy change. Examples include any combustion process, rusting of iron, and freezing of water.
Combustion is a type of exothermic chemical reaction that generates light and heat in most cases, and occurs fairly quickly.
What is an exothermic reaction?An exothermic reaction is one that when it occurs releases energy in the form of heat or light to the environment.
Characteristics of an exothermic reactionWhen this type of reaction occurs, the products obtained have lower energy than the initial reactants.Most of the exothermic reactions are oxidation, and when they are very violent they can generate fire, as in combustion.Combustion is a very fast oxidation reaction that occurs between materials called fuels and oxygen.Therefore, we can conclude that combustion is an example of an exothermic reaction that releases large amounts of heat, which can lead to fire.

How many grams of NaOH is needed to neutralize 90 mL of 1.5 N HCl?
mol = conc × v
= 1.5 × 0.09
= 0.135 moles of HCl
HCl + NaOH > NaCl + H2O
1 mole HCl = 1 mole NaOH
0.135 mol HCl = x
x = 0.135 mol NaOH
mass = mol × molar mass
= 0.135 × 40
= 5.4 g
NaOH = 23 + 16 + 1 = 40 g/mol

The value of probability density will be
The probability density function is nonnegative everywhere, and its integral over the entire space is equal to the terms "probability distribution function" and "probability function" .
What is probability density function?
In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be equal to that sample.
Probability density is the probability per unit length, in other words, while the absolute likelihood for a continuous random variable to take on any particular value is 0 (since there is an infinite set of possible values to begin with), the value of the PDF at two different samples can be used to infer, in any particular draw of the random variable, how much more likely it is that the random variable would be close to one sample compared to the other sample.

help!!!! the relative formula mass (Mr) of sodium fluoride is 42. Use the correct answer frim the box to complete the sentence.
Answer:
mole
Explanation:
Since Sodium Chloride is ionic, it cannot be considered a molecule as per the definition of a molecule requires each of its components to be bonded together.
The formula mass of a compound is the mass of its one molecule. Since molecule is the basic unit of a compound. Thus, the relative formula mass in grams is the mass of one molecule.
What is sodium fluoride?Sodium fluoride is an ionic compound formed by the combination of sodium and fluorine by loss of one electron from sodium to fluorine. The formula mass of fluorine is calculated from the atomic masses of sodium and fluorine.
Atomic mass of fluorine is 19 g/mol and mass of sodium is 23 g/mol. Here only one sodium and one fluorine is present. Hence the formula mass is 23+ 19 = 42.
This is the mass of one unit of NaF. Thus mass of one sodium fluoride molecule. Where as its molar mass may differ from the formula mass. Since the molar mass is the mass of one mole of the compound NaF. One mole of compound contains 6.02 × 10²³ molecules.

Hope this helps !!!If 3.31 moles of argon gas occupies a volume of 100 L what volume does 13.15 moles of argon occupy under the same temperature and pressure
Answer:
397 L
Explanation:
Recall the ideal gas law:
[tex]\displaystyle PV = nRT[/tex]
If temperature and pressure stays constant, we can rearrange all constant variables onto one side of the equation:
[tex]\displaystyle \frac{P}{RT} = \frac{n}{V}[/tex]
The left-hand side is simply some constant. Hence, we can write that:
[tex]\displaystyle \frac{n_1}{V_1} = \frac{n_2}{V_2}[/tex]
Substitute in known values:
[tex]\displaystyle \frac{(3.31 \text{ mol})}{(100 \text{ L})} = \frac{(13.15\text{ mol })}{V_2}[/tex]
Solving for V₂ yields:
[tex]\displaystyle V_2 = \frac{(100 \text{ L})(13.15)}{3.31} = 397 \text{ L}[/tex]
In conclusion, 13.15 moles of argon will occupy 397* L under the same temperature and pressure.
(Assuming 100 L has three significant figures.)
