The answer is B
I hope this helps have a great day
Explanation:
Answer:
<h2>The answer is option A</h2>
Explanation:
To find out if the object sink or float in water we must first find the density of the object
From the question
mass of object = 2 g
volume = 4 mL
The density is
We have the answer as
0.5 g/mL
The object will float on water since it's density is less than that of water which is
1.0 g/mL
Hope this helps you
Electrical energy is caused by moving particles that have a negative or positive charge. These charged particles are called electrons. The faster the electrons are moving, the more electrical energy they carry. Electrical energy commonly moves through a wire in an electrical circuit.
Answer: 48800g
Explanation:
Using the mathematical relation : Moles = Mass / Molar Mass
Moles = 488
Molar mass of CaCO3 = 40 + 12 + (16 x 3) = 100g/mol
Therefore
488 = mass / 100 = 48800g
