Answer:

The correct answer is - 5L.

Explanation:

From the ideal gas equation -

pv=nRT

p = pressure

v =volume

Here nRT is constant so

P would be inversely proportioned to v

So, p1/p2 = v2/v1

Putting values:

2/4(2) = v2/20 (p2 = 4 times of P1)

2/8 = v2/20

V2 = 5

Thus, the correct volume at new pressure would be - 5 L.

Which statement describes the masses of the particles that make up an atom?
Novay_Z [31]
The mass of the atom is equal to the sum of the number of protons and the number of neutrons. In a neutral atom, the number of protons is equal to the number of electrons.  The atomic number meanwhile of an atom is equal to the number of protons of the atom.

An atom has the following electron configuration 1s2s2sp63s23p64s2 How many valance electrons does this atom have?
JulijaS [17]

Answer:

The electron configuration for this atom is Calcium, which has 2 valence electrons.

Explanation:

Following the periodic table and with the electron configuration, you will end up with calcium, which has 2 valence electrons. (Always follow the electron configuration from left to right! It begins at hydrogen, then to helium... and so on.)

1s2 -> He....

2s2 -> Be....

2p6 -> Ne...

3s2 -> Mg...

3p6 -> Ar...

4s2 -> Ca.

Wear _______________________ when handling batteries, because they can explode or leak.
Basile [38]

The answer is: b. Safety glasses and acid-resistant gloves.

Battery acid (sulfuric acid) has pH = 0.

Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).

Chemical dissociation of sulfuric acid in water:  

H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).  

Sulfuric acid can come in contact with eyes and hands, so it is important to wear safety glasses and acid-resistant gloves.
