Answer:

Selenium ion.

Explanation:

The atomic number of selenium is 34 which means it have 34 protons and 34 electrons. In given statement 36 electrons are mentioned which means two extra electrons are gained by the selenium.

When an atom gain the electrons it form the negative ion.

Selenium by gaining the 2 extra electrons form Se²⁻.

Electronic configuration of Se:

Se₃₄ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁴

Se²⁻=  1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶

4p⁴ have four electrons, to attain the stable electronic configuration selenium gain to more electrons and complete the octet.

the triple point of co2 occurs at nearly 1000 times greater pressure and at a lower temperature than the triple point of h2o. ba
IceJOKER [234]

Since liquid CO2 cannot exist at pressures lower than 5.11 atm, the triple point is defined as 56.6 °C and 5.11 atm.

Are CO2 liquids explosive?

Although it can impair judgement at high doses, carbon dioxide is neither poisonous nor combustible. Asphyxiation is typically seen as the primary risk associated with CO2. The Boiling Liquid Expanding Vapour Explosion, however, is a serious risk connected to compressed CO2 (BLEVE)

What PSI does CO2 turn into liquid at?

Only at pressures more than 5.1 atm does liquid carbon dioxide form; the triple point of carbon dioxide is approximately 518 kPa at 56.6 °C. Depending on the pressure, the liquid's boiling point ranges from -70°F to +88°F. The expansion ratio when vaporised at 60°F is 535:1. CO2 is a gas or liquid.

Review the table detailing the mass of Jupiter’s moons and their distance from the planet. Which of Jupiter’s moons has the grea
olga nikolaevna [1]

The correct answer is Lo.  

The gravitational force between the two components is directly equivalent to the product of their masses and is inversely proportional to the distance separated between them. The largest planet in the solar system is Jupiter. It comprises 75 moons, and out of these moons, the four Galilean moons are very big in mass. These are Lo, Europa, Ganymede, and Callisto.  

Of these Galilean moons, the Lo moon is very close to Jupiter. The Ganymede moon is the largest of all the Galilean moons, but it is situated very far from Jupiter in comparison to Lo. Thus, the force of attraction between the Lo and Jupiter is very high, it exhibits the greatest gravitational force with Jupiter.

Nurse Antonio measured out 7 grams of sodium chloride (NaCI). Using dimensional analysis, calculate how many moles of NaCI he we
Neporo4naja [7]

Answer:

0.119 moles

Explanation:

Given that,

Mass measured by Nurse Antonio is 7 grams of NaCl

To find,

The no of moles of NaCl

Solution,

The number of moles is given by

n=\dfrac{m}{M}

m is given mass

M is molar mass

For NaCl, molar mass is 23+35.5 = 58.5 grams

So,

n=\dfrac{7}{58.5}\\\\n=0.119\ \text{moles}

Therefore, there are 0.119 moles of NaCl.
