Answer:

Considering the definition of mass molar and Avogadro's Number, there are 3.0115×10²⁹ molecules in 1 ton of hydrogen.

First, the molar mass of hydrogen H₂, that is, the amount of mass that a substance contains in one mole, is 2 g/mole.

In this case, being 1 ton = 1,000,000 grams, the number of moles that 1 ton of hydrogen contains is calculated as:

[tex]1,000,000 gramsx\frac{1 mole}{2 grams} = 500,000 moles[/tex]

On the other hand, Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole.

Then, the number of molecules that 500,000 moles of hydrogen contains is calculated as:

[tex]500,000 molesx\frac{6.023x10^{23} molecules }{1 mole}[/tex]= 3.0115×10²⁹ molecules

Finally, there are 3.0115×10²⁹ molecules in 1 ton of hydrogen.

Answer:

5542.37 K

Explanation:

Given that,

Initial volume, V₁ = 590 mL

Initial temperature, T₁ = -55°C = -55 + 273 = 218 K

Final volume, V₂ = 15 L

We need to find the final temperature of the gas. The relation between the volume and the temperature is given by :

[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

Where

T₂ is final volume of the gas

Put all the values in above relation,

[tex]T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{15\ L\times 218\ K}{590\times 10^{-3}\ L}\\\\T_2=5542.37\ K[/tex]

So, the required temperature is equal to 5542.37 K.

Answer:

96%

Explanation:

To find the percent yield, we can use this equation

[tex]\frac{Actual}{Theoretical} *100[/tex]

The actual yield of aspirin is 3.0 and the theoretical is 3.14 in this case, so just plug the numbers in.

[tex]\frac{3.0}{3.14} *100\\\\ =96[/tex]

Thus the percent yield is 96%

Answer:

1.25 M

Explanation:

Step 1: Given data

Mass of KI (solute): 20.68 g

Volume of the solution: 100 mL (0.100 L)

Step 2: Calculate the moles of solute

The molar mass of KI is 166.00 g/mol.

20.68 g × 1 mol/166.00 g = 0.1246 mol

Step 3: Calculate the molar concentration of KI

Molarity is equal to the moles of solute divided by the liters of solution.

M = 0.1246 mol/0.100 L= 1.25 M

Answer:

2.9 g of water are produced by 9.6 g of ammonium perchlorate

Note: The question is incomplete. The complete question is given below:

Ammonium perchlorate (NH₄ClO₄) is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) , and a great deal of energy. What mass of water is produced by the reaction of 9.6 g of ammonium perchlorate? Be sure your answer has the correct number of significant digits.

Explanation:

The reaction of ammonium perchlorate (NH₄ClO₄) to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) is shown in the balanced chemical equation given below:

2 NH₄ClO₄ →  N₂ +  Cl₂ + 2 O₂ + 4 H₂O

From the equation, 2 moles of ammonium perchlorate produces 4 moles of water, i.e. mole ratio of NH₄ClO₄ to H₂O = 2 : 4 = 1 : 2

molar mass of ammonium perchlorate, NH₄ClO₄ = (14 + 4 * 1 + 35.5 +16 * 4) = 117.5

molar mass of water,  H₂O = (2 * 1 + 16) = 18.0 g

mass of water produced = moles of ammonium perchlorate * 2 * molar mass of water

moles of perchlorate = mass / molar mass = 9.6/117.5

mass of water produced = 9.6/117.5 * 2 * 18.0 g  = 2.94 g of water

Therefore, 2.9 g of water are produced by 9.6 g of ammonium perchlorate

Can I have a brainliest

According to convection, the statement which describes how fluids change as they travel through the convection zone is  that they become more dense near the Sun's surface.

Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink.

Often the areas of heating and cooling are fixed, and allow convective cycles or currents to become established. For example, a saucepan of water over a flame may develop convective currents as the water is heated from below, rises to the surface, and cools. Once cooled enough, the water then sinks back to the bottom of the saucepan where the cycle is repeated, and the convective overturning continues.

Answer:

2.54 molMJ-1

Explanation:

The formation of CO2 is according to the equation;

C(s) + O2(g) -------> CO2

ΔHreaction = ΔHCO2 - [ΔHO2 + ΔHC]

ΔHO2 and ΔHC = 0 KJ

ΔHCO2 = -393.5 KJ

Hence;

ΔHreaction = -393.5 KJ - 0 KJ

ΔHreaction = -393.5 KJ

1 mol of CO2 yields -393.5 KJ/mol

The negative sign only means that heat was evolved in the process.

nCO2 = 1 mol CO2/393.5 KJ * 1 * 10^3 KJ/1MJ

nCO2 = 2.54 molMJ-1

The given statement is correct or true.  

• The alignment of electrons in an atom is termed as the electronic configuration.  

• The electrons in an atom seem to assume the alignment, which gives the atoms the least possible energy.  

• This alignment of electrons is the most stable alignment and is known as the atom's ground-state electronic configuration.  

• In the ground state of an atom, the electron first enters the lowest energy orbital and later subsequent electrons are aligned in order of increasing energy. This is known as the Aufbau principle.
