Hydrogen

Pog Pog Pog I'm a PogChamp

Hydrogen-1 serves as the starting reactant in fusion reactions in the sun. This is due to the sun's composition, which is around 70% hydrogen and 28% helium with 2% heavier components. As a result, hydrogen-1 is both the most prevalent and most likely to be employed in a fusion process in the sun.

Two hydrogen-1 nuclei are fused together to create a helium-4 nucleus in the sun's fusion reaction, which releases energy in the process. This is the most significant energy source in the sun and is known as the proton-proton chain reaction.

When two hydrogen-1 nuclei collide to generate a deuterium nucleus, a gamma ray is released as a result, starting the reaction. Then, this deuterium nucleus strikes another.A helium-3 nucleus is created from a hydrogen-1 nucleus, which also produces a gamma ray.

The reaction is finally finished when two helium-3 nuclei meet to produce a helium-4 nucleus, producing two gamma rays in the process. Since hydrogen-1 is the most prevalent element in the sun and the element that is most likely to be employed in the proton-proton chain reaction, it is the first reactant for a fusion process in the sun.

A deuterium nucleus is created by the collision of two hydrogen-1 nuclei, which is followed by a sequence of further processes that ultimately result in the development of a helium-4 nucleus.

Answer:

If the water velocity decreases, the rate of erosion increases

Explanation:

Answer:

15.5 g of MnO

Explanation:

The reaction is:

MnO₂ + 2NaCl + 2H₂SO₄ → Cl₂ + MnSO₄ + Na₂SO₄ + 2H₂O

We use the Ideal Gases Law to determine the moles of produced chlorine

P . V = n . R .T

We convert T° to Abs. value → 22°C + 273 = 295K

We convert Torr to atm → 710 Torr . 1atm /760 Torr =  0.934 atm

We replace: 10 L . 0.934 atm = n . 0.082 . 295K

( 10 L . 0.934 atm ) / (0.082 . 295K) = n →  0.386 moles

As the NaCl and the acid are in excess, we assume the MnO is the limiting reactant, and ratio is 1:1. so:

0.386 moles of chlorine came from 0.386 moles of MnO

We convert moles to mass: 0.386 . 40.3g/mol = 15.5 g

Answer:

the concentration of the solution is 2 mol/L.

Explanation:

Molarity is defined as the concentration of a solution expressed in terms number of moles of solute per liter of solution.

Mathematically Molarity is expressed as follow;

[tex]Molarity = \frac{Moles \ of \ solute}{Liters \ of \ solution} \\\\[/tex]

Given;

Volume of the solution, V = 0.45 L

Moles of the solute, n = 0.9 moles

The concentration of the solution [tex]= \frac{0.9}{0.45} = 2 \ mol/L[/tex]

Therefore, the concentration of the solution is 2 mol/L.

Explanation:

they would all have the same volumes

Answer: The volume for this gas is 0.732 L.

Explanation:

Given : No. of moles = 0.582 mol

Temperature = [tex]15^{o}C = (15 + 273) K = 288 K[/tex]

Pressure = 18.8 atm

Using the ideal gas equation, volume for the given gas is calculated as follows.

PV = nRT

where,

P = pressure

V = volume

n = number of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula.

[tex]PV = nRT\\18.8 atm \times V = 0.582 mol \times 0.0821 L atm/mol K \times 288 K\\V = \frac{0.582 mol \times 0.0821 L atm/mol K \times 288 K}{18.8}\\= \frac{13.761}{18.8}\\= 0.732 L[/tex]

Therefore, it can be concluded that the volume for this gas is 0.732 L.

Answer:

D)

Explanation:

seems like the most logical option out of all listed.

Answer:

D

Explanation:

Substance A is mixed with water and donates 0.4% of its H⁺ ions, therefore given substance is a weak acid & show poor conduction of electric current.

According to the Arrhenius theory of acids and bases, acids are those species which gives H⁺ ion to the solution.

In the question it is given that, substance A is mixed with water and it donates H⁺ ion, from this it is clear that given substance is acid. It is also mention that it donates only 0.4% of its H⁺ ion means partial dissociation is observed, so we conclude that this acid is weak in nature. And due to weak dissociation and less number of available H⁺ ion it did not conduct electricity effectively.

Hence, option (D) is correct i.e. it is weak acid and a poor conductor of electric current.

They can move at rates of up to four inches (10 centimeters) per year, but most move much slower than that. Different parts of a plate move at different speeds. The plates move in different directions, colliding, moving away from, and sliding past one another. Most plates are made of both oceanic and continental crust.

Answer:

We can solve this by the method of which i solved your one question earlier

so again here molar mass of C12H25NaSO4 is 288.372 and number of moles for 11900 gm of C12H25NaSO4 will be = 11900/288.372

which is almost = 41.26 moles

so to get one mole of C12H25NaSO4 we need one mole of C12H26O

so for 41.26 moles of C12H25NaSO4 it will require 41 26 moles of C12H26O

so the mass of C12H26O = 41.26× its molar mass

C12H26O = 41.26×186.34

= 7688.38 gm!!

so the conclusion is If you need 11900 g of C12H25NaSO4 (Sodium Lauryl Sulfate) you need C12H26O 7688.38 gm !!

Again i d k wether it's right or wrong but i tried my best hope it helped you!!

Answer:there are 44 grams

The total mass will be same of both side!!!!! ig so

Answer:

Option C - 1 mole

a) no of moles of solute = 4.1×0.05

so the mass of of sodium chloride present is 0.205×58.44

Mass of NaCl = 11.98 g

b) no of moles of solute = 1.8×0.01= 0.018

so the mass of of sodium chloride present is 0.018×58.44

Mass of NaCl = 1.05g

C) number of moles of solute is 1 mole

mass of solute is =58.44g

d) mass =9.35g

So the conclusion is that 1 mole is the correct answer!!!!
