Answer:
2, 1, 1, 4.
Explanation:
Hello there!
In this case, for the given chemical reaction:
We can see how there is one SO4 on the left and two on the right, thus, we add a 2 in front of H2SO4:
Next, since there are 8 atoms of hydrogen on the left and two on the right, we add a 4 in front of H2O to obtain:
Which is now balanced so the coefficients 2, 1, 1, 4.
Best regards!
Answer:

The device preserves the input power and simply trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.
Explanation:
Physical. When you simply desolve something with water, to don't actually change it. This action can be undone.
An example of a chemical reaction is when the cells within completely change. You you burn wood, you can't go back in time and un-burn it. Does that make sense?
