Answer:

La presión de un gas en un recipiente cerrado es inversamente proporcional al volumen del recipiente, cuando la temperatura es constante.LÑÑ

Explanation:

El volumen es inversamente proporcional a la presión: Si la presión aumenta, el volumen disminuye. Si la presión disminuye, el volumen aumenta.

How does energy from the some travel to earth

Finger [1]

Answer:

Bye the way, u welcome ;)

In heat transfer by radiation, energy is carried by electromagnetic waves from a starting point to the space surrounding it and does not involve contact with matter. The other forms of heat transfer cannot produce any of the energy that arrives to Earth through the vacuum of space.

Enter your answer in the provided box. Before arc welding was developed, a displacement reaction involving aluminum and iron(III

Likurg_2 [28]

Answer:

grams of iron = 2262.4 g

Explanation:

The balanced chemical equation should be represented first.

2Al + Fe2O3 → Al2O3 + 2Fe

find the limiting reactants by converting to moles.

covert 1.64 kg to grams = 1640 g

moles = mass/molar mass = 1640/27 = 60.7407407407 moles

60.7407407407 × 1 mol-rxn /2 = 30.37 mol-rxn

The limiting reactant is Fe2O3 Therefore it will determine the yield of Iron

2Al + Fe2O3 → Al2O3 + 2Fe

molar mass of Fe2O3 = 56 × 2 + 16 × 3 = 112 + 48 = 160 g

atomic mass of iron = 56

mass of iron in the reaction = 56 × 2 = 112 g

moles = mass/molar mass

mass = moles × molar mass

mass = 20.2 × 160 = 3232 g

if 160 g of Fe2O3 give 112 g of iron

3232 g of Fe2O3 will give ? grams of iron

grams of iron = 3232 × 112/ 160

grams of iron = 361984 /160

grams of iron = 2262.4 g

In chemical reactions, there is a conservation of(1) energy, volume and mass

Lubov Fominskaja [6]

Answer: option (3) energy, charge and mass.


Explanation:


1) The conservation of energy is a universal principle: energy is neither created nor destroyed. This is the first law of thermodynamic.


2) Mass conservation is another universal principle: mass is neither created nor destroyed. This principle is the base of the stochiometry: thas mass of the reactans equal the mass of the products. Another consequence, since the atoms are not transformed in the chemical reactions, is that the number of each kind of atoms in the reactants equal the number of the same kind of atoms in the products.


3) The third principle is the conservation of charge. Also, charge is neither created nor destroyed. The electrons gained/lost by one species are lost/gained by other species. So, when one atom or molecule is oxidized other is reduced.

I need help on 18b. i’m confused on how you would work it.

AfilCa [17]

For a and b, you need to divide it by Avogadro’s number to find the answer.

a. (6.022x10^23)/6.022x10^23 = 1 mole of Ne
b. (3.011x10^23)/6.022x10^23 = 0.5 moles of Mg

For c and d, you’ll use the mass provided divided by the molar mass to find the number of moles.
Pb molar mass = 207.2 g/mol

c. (3.25x10^5)/207.2 = 1.57x10^3 moles of Pb
For d, I can’t tell if is Cu, C or something else but you can follow the steps above to solve the problem.
