Chemistry
1 answer:
Dafna11 [192]3 years ago
8 0

Answer:

1 oxygen atoms

Explanation:

When barium combines with oxygen to form an ionic compound, it will only require just an oxygen atom.

An ionic compound is formed due to the electrostatic attraction between oppositely charged ions

A metal loses electrons to be gained by the non - metal and in the process they attract each other with a force.

 Barium has two valence electrons, to be stable, it loses the two;

 Oxygen has six valence electrons, to be stable it will gain two valence electrons to form an octet.

 So;

     One barium atom will successfully bind with One oxygen atom to form

               BaO

At-57 °C and 1 atm, carbon dioxide is in which phase? View Available Hint(s) Phase diagrams for water (Figure 1)and carbon dioxi
goblinko [34]

Answer:

Gas

Increase the pressure

Explanation:

Let's refer to the attached phase diagram for CO₂ (not to scale).

<em>At -57 °C and 1 atm, carbon dioxide is in which phase?</em>

If we look at the intersection between -57°C and 1 atm, we can see that CO₂ is in the gas phase.

<em>At 10°C and 2 atm carbon dioxide is in the gas phase. From these conditions, how could the gaseous CO₂ be converted into liquid CO₂?</em>

Since at 10°C and 2 atm carbon dioxide is below the triple point, the only way to convert it into liquid is by increasing the pressure (moving up in the vertical direction).

What does CoH12O6 tell you about the glucose molecule?
Leokris [45]

Answer:

Glucose = C6H12O6

molecular mass = 6(12) + 12(1) + 6(16)

= 72 + 12 + 96

= 180 g

Explanation:

Glucose has a chemical formula of: C6H12O6 That means glucose is made of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. ... Glucose is produced during photosynthesis and acts as the fuel for many organisms.
