The mass of HNO₃ is 19.17kg.
How do chemical equations work?Chemical equations are symbolic depictions of chemical reactions where the reactants and products are stated in terms of their respective chemical formulae.
The equation of the reaction is;
4NO₂(g) + O₂(g) + 2H₂O(l) → 4HNO₃(aq)
There is a plenty of water and oxygen. Because it controls the amount of product formed, NO2 is referred to as a limiting reagent. With the aid of the following formula, the moles of NO2 are determined:
Mass of NO₂ produced = 14 kg
Molar mass of NO₂ = 46 g/mol
Number of moles of NO₂ = 14 × 10³ g/46 g/mol
Number of moles of NO₂ = 304.34 moles.
Utilizing stoichiometry,
HNO₃ will be produced from 4 moles of NO₂
This indicates that 304.34 moles will produce,
4/4×304.4 = 304.4.
The first equation can be used to get the mass of HNO₃ and we will obtain,
Molar mass of HNO₃ = 63gm/mol
Molar mass of HNO₃ = 63×304.34
Molar mass of HNO₃ = 19173.42 (or) 19.17.

the solubility product constant of silver chromate ag2cro4 is 1.12 x 10^-12 m. calculate the molar solubility of the salt.
The molar solubility of salt is 6.542 x 10⁻⁵ mol/L
What is molar solubility?It is the number of moles of solute in a saturated solution that is one litre in size. It is expressed in moles per litre.A compound's capacity to dissolve in a given substance is known as its molar solubility (M), which is a unit of measurement. Molar solubility is measured as moles/L and is more specifically the maximum number of moles of a solute that can dissolve in one litre of solvent. The solution is said to be saturated when the amount of solute it can dissolve in one litre of solvent equals the amount of moles dissolved in one mole of solvent.
There are several factors that affect M's value. The Ksp value of the solubility product constant is significant. Each compound's measure of how readily a substance dissolves has a fixed value. Calculating the value of M also requires knowledge of the chemical reaction's product-to-reactant ratio. The reaction's stoichiometry is what is meant by this
Co(OH)₂ dissociates in solution according to the equation:
Ag₂CrO₄ → 2Ag⁺ + CrO₄²⁻.
∵ Ksp = [Ag⁺]²[CrO₄²⁻] = (2s)²(s) = 4s³.
∴ 4s³ = 1.12 x 10⁻¹².
∴ s³ = 1.12 x 10⁻¹²/4 = 2.80 x 10⁻¹³.
∴ s = ∛(2.80 x 10⁻¹³) = 6.542 x 10⁻⁵ mol/L
Thus the molar solubility of salt is 6.542 x 10⁻⁵ mol/L

Water beads up on the surface of a waterproof coat. What can you say about the bonds in the molecules on the surface of the coat?
Answer: Molecules are not attracted
Explanation:
Answer:
The bonds must be non-polar.
Explanation:
The water molecules are polar, so they wouldn't be attracted to the surface. This means the water would bead up and curve away from the surface it landed on.
When water beads up, this happens because the water molecules are more strongly attracted to each other by the polar bonds than they are to the surface by non-polar interactions.
To summarize:
On a nonpolar layer, water beads up because the attraction to each other is stronger than the surface.
Hope this explained it well.
how many grams of chlorine gas are produced in the following reaction from 0.490 g hydrogen and 50.0 g chlorine? which substance is the limiting reactant?
The HCl concentration formed is 17.6 g and the limiting reactant is hydrogen.
In this case, based on the information provided, the grams of HCl required can be calculated by first identifying the limiting reactants in moles of each reactant.
1:1 mole ratio
nH₂ = 0.490 g H₂ x 1 mol H₂ / 2.02 g H₂ = 0.242 mol H₂
nCl₂ = 50.0 gCl₂ x 1 mol Cl₂ / 70.9 g Cl₂ = 0.705 mol Cl₂
From this we conclude that hydrogen is the limiting reactant and use 1:2 molar ratio with HCl having a molar mass of 36.46 g/mol:
mHCl = 0.242 mol H2; x 2 mol HCI/1 mol H2. x 36.6 g HCl/1 mole HCl
mHCl = 17.6 g HCl
Therefore, the HCl concentration formed is 17.6 g and the limiting reactant is hydrogen.

A barge pulls a freighter ship with a constant net horizontal force of 7500 N and causes the ship to move through the harbor. How much work is done on the ship if it moves 2000m?
work done on the ship if it moves 2000m is 15×[tex]10^{6}[/tex]J
When an external pulling force is applied to an object, the object moves from one place to another or we can simply say that it changes its position. The amount of work required to move the object from its initial position to the final position is directly proportional to the force applied to the object.
Work done depends on two main components that is force and displacement of an object. The displacement of an object must happen along the line of action of the force in order for the force to do work on the object.
Work has units of energy because it is defined as an amount of (transferred) energy, so work usually has units of J (joules).
To calculate work the formula that we use is;
W = F × d, where W = work done, F = Force and d = distance
W = 7500N × 2000m
W = 15×[tex]10^{6}[/tex]J

Ionization energy increases with increase in electronegativity. The ionization energy of aluminium is less than that of magnesium because it is easier to remove an electron from the p orbital than that from an s orbital.
What is ionization energy?Ionization energy is the minimum energy required to remove a valence electron from the atom. Thus it depends on the orbital and electronegativity of the atom.
In the case of magnesium the valence electrons are in s orbital and that of aluminium is p orbital. It is easy to remove an electron p orbital than that from a s orbital. Thus Mg has higher ionization energy than Al.
In the case of phosphorous, the valence shell is half filled making it highly stable and thus higher ionization energy. Out of the four valence electrons in p orbital of sulphur, one can be easily removed and thus has lower ionization energy.
In the case of Be the same can be applied,as in Mg, that removing its valence electron from s orbital is hard than to remove an electron from the p orbital of boron.

The new volume of oxygen If 30.0 L of oxygen are cooled from 473ºK to 274°K at constant pressure, is 17.38 L.
to calculate the new volume of oxygen we can use the charles law.
Where in Charles law of gases states that at constant pressure, volume of the gas is directly proportional to the temperature of the gas, i.e.

According to the question,we can calculate the new volume of oxygen as below :
V₁/T₁ = V₂/T₂, where
V₁ = initial volume of gas = 30 L
T₁ = initial temperature of gas = 473ºK
V₂ = new volume of gas = ?
T₂ = new temperature of gas = 274ºK
On putting all these values on the above equation, we get
V₂ = (30)(274ºK) / 473ºK = 17.38 L.
