Precipitation is the correct answer
Answer:
Explanation:
The formation of a gas is a clue to chemical changes. The bubbles of gas that you observed form when an antacid is dropped into water is an example of change. ... After ice melts into liquid water, you can refreeze it into solid ice if the temperature drops. Freezing and melting are physical changes.
it hydrostatic im not sure
Answer:
I = 2.1 A
Explanation:
This is physics, but I will answer here either way.
First, the battery produces a voltage of 12 V in a resistor with 6 ohm, and we want the current flow (I). We need to apply the following expression:
V = R * I (1)
This is the Ohm's law. From here we can solve for I and:
I = V/R (2)
Now, we just need to replace the data and solve for the current:
I = 12.6 / 6
<h2>
I = 2.1 A</h2>
Hope this helps
