Element x reacts with oxygen to produce x2o3 in an experiment it is found that 1.0000 g of x produces 1.1xxx g of x2o3 what is t
8_murik_8 [283]

Since X is 1 g, therefore O must be 0.1 g. Therefore:

moles O = 0.1 g / (16 g / mol) = 0.00625 mol

 

We can see that for every 3 moles of O, there are 2 moles of X, therefore:

moles X = 0.00625 mol O (3 moles X / 2 moles O) = 0.009375 mol

 

Molar mass X = 1 g / 0.009375 mol

<span>Molar mass X = 106.67 g/mol</span>

Which scenario would adhere to the law of conservation of energy?
Nina [5.8K]

Examples of scenarios that would adhere to the law of conservation of energy are as follows:

  • In a loudspeaker, electrical energy is converted into sound energy.
  • In a microphone, sound energy is converted into electrical energy.
  • In a generator, mechanical energy is converted into electrical energy

<h3>What is law is conservation of energy?</h3>

The law of conservation of energy states that energy cannot be created nor destroyed but is conserved when it is transferred from one form to another.

The law of conservation of energy is obeyed by majority of natural and artificial systems. For example;

  • In a loudspeaker, electrical energy is converted into sound energy.
  • In a microphone, sound energy is converted into electrical energy.
  • In a generator, mechanical energy is converted into electrical energy

What happens when the concentration of water inside a cell is lower than the concentration of water outside the cell?
adell [148]

Answer:

Water outside the cell will flow inwards by osmosis to attain equilibrium

Explanation:

In the hypotonic environment, the concentration of water is greater outside the cell and the concentration of solute is higher inside. A solution outside of a cell has a lower concentration of solutes relative to the cytosol.

If concentrations of dissolved solutes are greater inside the cell, the concentration of water inside the cell is correspondingly lower. As a result, water outside the cell will flow inwards by osmosis to attain equilibrium.

Osmosis is a process by which molecules of a solvent tend to pass from a less concentrated solution into a more concentrated one through a semipermeable membrane.

The mass of a neutron is 1.67 x 10^-24 g. Approximately what number of neutrons would equal a mass of one gram?
Lelechka [254]
1. a sulfur-32 atom contains 16 protons, 16 neutrons, and 16 electrons. what is the mass (in grams) of a sulfur-32 atom?

The mass in grams of a sulfur-32 atom is 32.

That is how the isotopes are identified, showing the mass number of the isotope, which is the sum of protons and neutrons: 16 protons + 16 neutrons = 32 mass number = mass in grams of the isotope.

2. the mass of a neutron is 1.67 x 10-24 g. approximately what number of neutrons would equal a mass of one gram?

divide 1 gram by the number of neutrons per gram:

number of neutrons = 1 g / 1.67 * 10 ^ - 24 g / neutrons = 0.5998 * 10 ^ 24 neutrons = 5.998 * 10 ^23 neutrons.

Determinar los números cuánticos del electrón desapareado en el átomo del cloro (Z = 17) y diga si es paramagnético
Musya8 [376]

Answer:

n = 3

l = 1

ml = +1

ms = +1/2

Es paramagnético

Explanation:

Siguiendo las reglas de llenado de orbitales, los 17 electrones del cloro se llenan así:

1S = <u>⇅</u>

2S = <u>⇅</u>

2P = <u>⇅</u> <u>⇅</u> <u>⇅</u>

3S = <u>⇅</u>

3P = <u>⇅</u> <u>⇅</u> <u>↑</u>

<u />

El número cuántico principal n, es el nivel energético donde se encuentra este electrón:

n = 3 (Porque está en el orbital 3P

El número cuántico secundario, l, para el orbital 3P es  = 1:

l = 1

El número cuántico magnético, ml, es determinado por la posición del electrón. Como está en el tercer orbital 3P:

ml = +1

Y el número cuántico de spin, ms (↑ = +1/2; ↓ = -1/2)=

ms = +1/2

Dado que el último electrón se encuentra desapareado, el cloro es paramagnético dado que el espín de el último electrón no tiene su electrón complementario haciendo que este compuesto pueda interactuar con un campo magnético.
