What is the ideal gas equation?The ideal gas equation can be defined as an equation that describes the behavior of an ideal gas. This equation gives by the product of the volume and pressure is equal to the product of the moles of gas, gas constant, and absolute temperature.
The mathematical form of the ideal gas law is given as follows:
PV = nRT
Where n is the moles, V is the volume, R is the universal gas constant and P is the pressure.
The temperature of the N₂ , T = 0° C = 273 K
The pressure of the gas at STP, P = 1 atm
The value of the universal gas constant, R = 0.082 atm L/K mol
The number of moles of N₂, n = 0.881 mol
Fill in the values n, R, P, and T in the equation, and we get:
1 × V = 0.881 × 0.082 × 273
V = 19.72 L

What must be happening to the forces of attraction between particles when a change of state occurs?
Answer:
The particles need energy to overcome the attractions between them. As the liquid gets warmer more particles have sufficient energy to escape from the liquid. Eventually even particles in the middle of the liquid form bubbles of gas in the liquid.

A reaction is expected to produce 28.3 moles of hydrogen gas. If the hydrogen is collected at 297 K and 1.08 atm, what is the volume? 305 L H2 639 L H2 948 L H2 1,240 L H2
Answer:
The correct answer is 639 L H₂
Explanation:
We use the ideal gas equation:
We have the following data:
n = 28.3 mol
T= 297 K
P= 1.08 atm
R= 0.082 L.atm/K.mol (gas constant)
We introduce the data in the gas equation to calculate the volume (V):
PV=nRT
⇒V =nRT/P = (28.3 mol x 0.082 L.atm/K.mol x 297 K)/(1.08 atm) = 638.2 L ≅ 639 L
Therefore, the correct option is 639 L H₂
Answer:
639 L H2

how does reactants in photosynthesis combine to make atoms molecules
Answer:
hope this helps
Explanation:
Photosynthesis
Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phos, "light", and sunthesis "putting together". In most cases, oxygen is also released as a waste product. Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

2NO+2CO N 2 +2CO 2 There are 3.0 g of NO and 3.0 g of CO reacting . What is the limiting reactant ?
Answer: NO
Explanation:
As per the given balanced equation, 2 moles of NO reacts with 2 moles of CO. Hence, 3 g or 1.07 moles of CO needs to react with the same number of moles of NO. But we have only 3 g or 0.1 mole of NO. Hence, NO is the limiting reactant.
What is limiting reactant ?A limiting reactant in a reaction is the reactant which is fewer in amount or consume early without complete reaction with other reactants. Hence, as soon as this reactant is consume, the reaction stops.
Given 2 moles of NO reacts with 2 moles of CO.
molar mass of NO = 30 g/mol
molar mass of CO = 28 g/mol.
Number of moles in 3 g of CO = 3/28 = 1.07 moles
number of moles in 3 g of NO = 3/30 = 0.1 moles.
1.07 moles of CO needs 1.07 moles of NO. But only 0.1 moles are present.
Therefore, NO is the limiting reactant in this reaction.

Calculate the molarity of a solution that contains 85.0 g of Zn(C2H3O2)2 in 250. mL of solution (don't forget to convert mL to L first). Round to the nearest hundredth.
Answer:
[Zn(C₂H₃O₂)₂] = 1.85M (3 sig-figs accurate to 0.01 Molar)
Explanation:
Concentration is defined as amount of solute in a specified volume of solution. That is, Concentration = mass of solute/volume of solution (solution = solute + solvent). When concentration is in terms of Molar values the essential relationship is Molarity(M) = moles solute / volume of solution in liters.
For this problem => first, convert mass of Zn(C₂H₃O₂)₂ into moles and then the volume of solution into liters. Take ratio of moles/volume of solution (L).
=> Molar Concentration = moles of Zn(C₂H₃O₂)₂ / Liters of solution
moles of Zn(C₂H₃O₂)₂ = 85.0 grams Zn(C₂H₃O₂)₂ / formula weight of Zn(C₂H₃O₂)₂ = 85.0g/183.5g·mole⁻¹ = 0.463 mole Zn(C₂H₃O₂)₂.
Volume of solution in Liters = 250ml / 1000ml/L = 0.250 liters
Molarity of Zn(C₂H₃O₂)₂ solution = 0.463 mole Zn(C₂H₃O₂)₂ /0.250 liters of solution = 1.85 Molar in Zn(C₂H₃O₂)₂
_____________
Note: The symbiology convention for 'molar solution concentration' is to place brackets around the molecular formula. That is, [Zn(C₂H₃O₂)₂] = 1.85M

why is atomic radi measured using the nuclues from 2 of the same atoms
Explanation:
Atomic radii is measured using the distance between nucleus of 2 atoms rather than the distance between the nucleus and outermost shell because:
- There is no clear/sharp boundary of the orbital. This is why it is called an electron cloud.
- Also, the exact location of the electron is not known. What is known is the probability of finding the electron there.
Due to this, it is not possible to measure the atomic radii precisely. That's why the distance between the nucleus of two atoms is used.

Fe2O3 (s) + 2 Al (s) ---> 3 Fe (l) + Al2O3 (s) Based on the thermite reaction, how much aluminum oxide (Al2O3) is formed from 8.0 grams of aluminum (Al)?
Answer:
15.3 g
Explanation:
Fe₂O₃ (s) + 2Al (s) → 3Fe (l) + Al₂O₃ (s)First we convert 8.0 grams of aluminum into moles, using its molar mass:
8.0 g Al ÷ 27 g/mol = 0.30 mol AlThen we convert 0.30 moles of aluminum into moles of aluminum oxide, using the stoichiometric coefficients:
0.30 mol Al * [tex]\frac{1molAl_2O_3}{2molAl}[/tex] = 0.15 mol Al₂O₃Finally we convert 0.15 moles of Al₂O₃ into grams, using its molar mass:
0.15 mol Al₂O₃ * 102 g/mol = 15.3 g Al₂O₃A horse weighs 240 kg. If its running at a speed of 18 m/s, what's the linear momentum of the horse
