Explanation:

An isotope is defined as the specie which contains same number of protons but different number of neutrons.

For example, $_{1}H^{+}$ is an isotope of hydrogen atom.

The number at the bottom of the symbol of an element represents the number of protons present in the atom.

So, the given atom contains only one proton and 0 neutrons. Also, when an atom is neutral in nature then it contains same number of protons and electrons.

But as the given atom has one +1 charge which means that it contains 0 electrons.

Thus, we can conclude that $_{1}H^{+}$ contains 1 proton, 0 neutrons and 0 electrons.

<h3>Answer:</h3>

H+ contains 1 proton, 0 neutrons, 0 electrons.

<h3>Explanation:</h3>

An atom is the smallest particle of an element that can take part in a chemical reaction.
Atoms are made of sub-atomic particles neutrons and protons found in the nucleus and electrons found in the energy levels.
A hydrogen atom contains 1 proton and 0 neutrons in the nucleus and 1 electron in the energy levels.
A hydrogen atom loses an electron to form an ion with 1 proton, 0 neutron and 0 electron.

The behavior of real gases most closely resembles that of ideal gases under conditions of

blsea [12.9K]

High temperature and low pressure. At high temperature, the kinetic energy of the gas particles increases and they move farther from each other. At low pressure, the gas particles are less likely to collide with each other.

What is the change in enthalpy when 180 g of water vapor condenses at 100°C? (AH, = 40.67 kJ/mol)

Snowcat [4.5K]

Answer:

$Q=-407kJ$

Explanation:

Hello there!

In this case, considering that the heat has two forms, sensible (variable temperature) and latent (constant temperature), we can notice that phase changes account for latent heat as the temperature remains the same. In such a way, given the enthalpy of vaporization of water, 40.67 kJ/mol, the enthalpy of condensation (reverse process) is the negative value, -40.67 kJ/mol; therefore, the associated latent heat would be:

$Q=180g*\frac{1mol}{18.02g} *-40.67\frac{kJ}{mol} \\\\Q=-407kJ$

Best regards!

1. How many grams are in 1.7 x 10^23 particles of Cl2?

alisha [4.7K]

Answer: 1. 20.0 grams

2. 0.272 moles

3. B) Mass --> Moles --> Volume

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given molecules}}{\text{Avogadros number}}$ or

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ or

Putting in the values we get:

1. $\text{Number of moles of} Cl_2=\frac{1.7\times 10^{23}}{6.023\times 10^{23}}=0.282moles$

Mass of $Cl_2=moles\times {\text {Molar mass}}=0.282mol\times 71g/mol=20.0g$

2. $\text{Number of moles of NaCl}=\frac{3.28\times 10^{23}}{2\times 6.023\times 10^{23}}=0.272moles$

3. $\text{Number of moles of water}=\frac{26g}{18g/mol}=1.44moles$

Volume of water = $moles\times {\text {Molar volume}}=1.44mol\times 22.4L/mol=32.4L$

What is the current in amperes if 1200 na+ ions flow across a cell membrane in 3.5 μs ? the charge on the sodium is the same as

lbvjy [14]

Charge = 1200 * 1.6 * 10^-19 = 1920 * 10^-19
Time = 3.5 Âµs = 3.5 * 10^-6 s
But Current = charge/time = (1920 * 10^-19) / (3.5 * 10^-6)
So Current becomes 548.5714 * 10^(-19-(-6))
So we have 548.5714 * 10^(-19 + 6) = 548.5714 * 10^(-13)
So we have 5.485714 * 10^(-15)
