Answer:
5 cm³.
Explanation:
From the question given above, the following data were obtained:
Volume of water = 35 mL
Volume of water + Rock = 40 mL
Volume of Rock =.?
The volume of the rock can be obtained as follow:
Volume of Rock = (Volume of water + Rock) – (Volume of water)
Volume of Rock = 40 – 35
Volume of Rock = 5 mL.
Finally, we shall convert 5 mL to cm³.
This can be obtained as follow:
1 mL = 1 cm³
Therefore,
5 mL = 5 mL × 1 cm³ / 1 mL
5 mL = 5 cm³
Thus, we can say that the volume of the rock is 5 cm³.
Answer is: solid is the state in which matter has a definite shape and volume.There are two types of solids:crystalline (solids that have a very orderly, 3-dimentional arrangement of atoms or molecules) and amaorphous (composed of atoms or molecules that are in no particular order).
Plasma is is the state of matter that does not have a definite shape or volume. <span>Plasmas and some solids (metals) conduct electric current.</span>
Answer:
CuO + H₂SO₄ ⟶ CuSO₄ + H₂O
Explanation:
The most likely reaction is a <em>double displacement</em>, in which Cu and H trade partners.
This gives
CuO + H₂SO₄ ⟶ CuSO₄ + H₂O
The equation is already balanced, so no further work is necessary.

Answer:
0.09425
Explanation:
The reactant is in solid phase and therefore has zero partial pressure.
The products have the same mole ratio (1:1) and will have the same partial pressure = 1/2 × 0.614 atm = 0.307 atm
Kp = (NH3)(H2S) = 0.09425
