Answer:

2L of nitrogen gas will be needed

Explanation:

Based on the following reaction:

N₂ + 3H₂ → 2NH₃

1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia.

If 6L of hydrogen (In a gas, the volume is directly proportional to the moles, Avogadro's law) react, the volume of nitrogen gas required will be:

6L H₂ * (1mol N₂ / 3 moles H₂) =

Option C, Smut

Explanation:

Corn smut is a condition in which mushroom-like tumors or galls appear on different part of the plant. This is caused by fungus Ustilago zeae. Corn smut is edible and appears grayish white with spony texture in the early stages of the infection promptly found on corn ear or tassel.

Hence, option C is correct

option c is the right answer❤️

Answer:

This is called static electricity, which means “non-moving electricity” The electrons have the power to pull very light objects (with a positive charge) toward them – like the soda can

Explanation:

Based on the information given, the image represents a negatively charged fluoride atom (Option B)

An atom is composed of a centrally placed nucleus (containing protons and neutrons) and a cloud of electrons revolving round it.

From the question given above, the following data were obtained:

Charge = Proton – Electron

Charge = 9 – 10

Charge = –1

Note

Element with proton number of 9 is fluorine

Thus, we can conclude that the image represents a negatively charged fluoride ion (Option B)

Explanation:

Answer:

A-B : solid wax heating

B-C : melting

C-D : liquid wax heating

D-E : Boiling

E-F : Gaseous wax heating

A sample of solid candle wax is put into a pot on the stove. Heat energy is transferred to the wax at a constant rate by the burner on the stove. A-B is solid wax heating, B-C is melting, C-D is liquid wax heating, D-E is Boiling and E-F is Gaseous wax heating.

A heating system is a device that uses thermal energy to keep indoor temperatures within a house, workplace, or other structure at a comfortable level. portion of an HVAC system frequently. A heating system can be dispersed or centrally located.

The movement of minuscule atoms, molecules, or ions in solids, liquids, and gases produces heat energy. From one thing to another, heat energy can be exchanged. Heat is the flow or transfer that occurs as a result of the temperature differential between two objects.

When heat is applied to some substances, chemical changes or reactions occur that result in the formation of one or more new compounds with unique features.

Thus, A-B is solid wax heating, B-C is melting, C-D is liquid wax heating, D-E is Boiling and E-F is Gaseous wax heating.

Answer:

[tex]\boxed {\boxed {\sf +6}}[/tex]

Explanation:

A compound must have a net charge of 0. The charges have to balance each other out and equal 0.

We have the compound sulfur trioxide with a chemical formula of SO₃.

Oxygen (O) has an oxidation state of -2, which means it will have a charge of -2 in the compound. However, note there is a subscript after the O in the chemical formula. Therefore, there are 3 oxygen atoms in the compound and each one has a charge of -2. The oxygen has an overall charge of -6 because 3*-2 = -6.

There is only one atom of sulfur (there is no subscript, so a 1 is implied). It has to balance out the -6 charge of the oxygen atoms, so it must be +6.

The oxidation number for sulfur is +6 in the compound sulfur trioxide.

+6

Vapor Information

Explanation:

Atmospheric rivers are relatively long, narrow regions in the atmosphere like rivers in the sky that transport most of the water vapor outside of the tropics. Not all atmospheric rivers cause damage, and most are weak systems that often provide beneficial rain or snow that is crucial to the water supply.

Explanation:

The faster particles move, the more kinetic energy they have. Within a given substance, such as water, particles in the solid state have the least amount of kinetic energy. Particles in the liquid state move faster than particles in the solid state. Therefore, they have more kinetic energy.

Answer:

[tex]206.6\ \text{kPa}[/tex]

Explanation:

[tex]P_1[/tex] = Initial pressure = 200 kPa

[tex]P_2[/tex] = Final pressure

[tex]T_1[/tex] = Initial temperature = [tex]30^{\circ}\text{C}[/tex]

[tex]T_2[/tex] = Final temperature = [tex]40^{\circ}\text{C}[/tex]

We have the relation

[tex]\dfrac{P_2}{P_1}=\dfrac{T_2}{T_1}\\\Rightarrow P_2=\dfrac{T_2}{T_1}P_1\\\Rightarrow P_2=\dfrac{40+273.15}{30+273.15}\times 200\\\Rightarrow P_2=206.6\ \text{kPa}[/tex]

The pressure that would be exerted after the temperature change is [tex]206.6\ \text{kPa}[/tex].

Answer:

[HClO₄] = 0.35 M

Explanation:

Neutralization reaction is:

HClO₄ + LiOH  →  LiClO₄  +  H₂O

In this case, we have a titration between a weak acid and a strong base.

In chemistry it is also called an acid base equilibrium.

HClO₄  +  H₂O  ⇄  ClO₄⁻   +  H₃O⁺       Ka

The weak acid is firstly neutralized by the strong base, in order to have a buffer solution before the equivalence point.

When we reach the equivalence point, mmoles of acid = mmoles of base and there is a formula to determine it so:

M acid . Volume of acid = M base . Volume of base

M acid . 100 mL = 0.75 M . 46.9 mL

M acid = (0.75 M . 46.9 mL) / 100 mL → 0.35 M

Answer:

56.94759 grams of NO2

Explanation:

Stoichiometric Equation:

1 S + 6 HNO3 → 1 H2SO4 + 6 NO2 + 2 H2O.

This is so you can create ratios between each compound in the reaction, and identify the limiting and excess reactants to determine exactly how much can be produced?

The coefficients or molecular quantity of each compound in the balanced equation represents the amount of moles.

To figure out how much can be produced, you have to convert 59.54 g of S into moles of S and 78 g of HNO3 into moles of HNO3.

A reference such as a periodic table can be very helpful as it has the atomic mass of each element which is the mass with respect to 1 mol of that element.
