If all the reactors are used, the pressure inside the flask will most likely increase to 4 atm.

<h3>What is atmospheric pressure?</h3>

Atmospheric pressure is a force per unit area exerted by the air in the atmosphere on the Earth's surface. The value of atmospheric pressure above sea level is 1013.25 hPa.

<h3>What influences the variation of atmospheric pressure?</h3>

The atmospheric pressure varies from different meteorological factors such as:

Decreases with altitude.
It varies according to latitude, the lowest atmospheric pressure at sea level is reached in the equatorial latitudes.
The equatorial zone has high atmospheric pressures for dynamic reasons derived from the Earth's rotation.

According to the above, if all the reactors are used at atmospheric pressure, it will most likely increase.

Note: This question is incomplete because some information is missing. However I can answer it based on my prior knowledge.

Which noble gas will Selenium try to resemble when it becomes an ION?

lapo4ka [179]

Answer:

Krypton

Explanation:

When Selenium forms an ion, it is trying to become krypton which is a noble gas.

Selenium belongs to the oxygen group on the periodic table. In this group, the atoms prefers to gain two electrons to complete their octet. When selenium gains two electrons, its octet is complete.

This will make the atom resemble krypton on the periodic table of elements.

This structure which is an octet confers a special stability on the element.

Which units are used to measure both velocity and speed? Select three options

Ede4ka [16]

Answer and Explanation:

The options aren't listed in your question, but here are some units that are regularly and normally used (in the classroom and in the outside world):

(The SI unit of distance and displacement is the meter. The SI unit of time is the second.)

Meters per Second (m/s)

kilometers per hour (km/hr)

kilometers per second (km/sec)

To find the average speed, you do distance divided by time.

To find the average velocity, you do the final position minus the initial position, divided by the final time minus the initial time.

A flask contains 6g hydrogen gas and 64 g oxygen at rtp the partial pressure of hydrogen gas in the flask of the total pressure

Alex

Answer:

B.3/5p

Explanation:

For this question, we have to remember "Dalton's Law of Partial Pressures". This law says that the pressure of the mixture would be equal to the sum of the partial pressure of each gas.

Additionally, we have a proportional relationship between moles and pressure. In other words, more moles indicate more pressure and vice-versa.

$P_i=P_t_o_t_a_l*X_i$

Where:

$P_i$ =Partial pressure

$P_t_o_t_a_l$ =Total pressure

$X_i$ =mole fraction

With this in mind, we can work with the moles of each compound if we want to analyze the pressure. With the molar mass of each compound we can calculate the moles:

moles of hydrogen gas

The molar mass of hydrogen gas ( $H_2$ ) is 2 g/mol, so:
