Three signs that a chemical change has taken place is 1) color change 2) formation of gas bubbles 3) a change in temperature ( if you have ever bleached your hair the reason why it is warm to the touch is because of a chemical reaction)
Caves are hollow spaces in Earth's crust.
Answer: D) Monitor the sea level over set period of time.
Since global warming causes land ice to melt, that water goes into the ocean to raise sea levels. This is an effect of global warming.
Choices A through C are things to measure if you want to measure causes of global warming, so we can rule those out.
There are two equations given in the question. The type of reaction shown can be easily judged, if one takes a closer look at the equations.
1. <span>Ba(ClO3)2(s) ----> BaCl2(s) + 3O2(g) ------- Redox
2. </span><span>CaO(s) +CO2(g) ----> CaCO3(s) -------- None.
I hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span>
Answer:
155 A
Explanation:
Given data
- Transported charge (Q): 93.0 Coulomb
- Elapsed time (t): 601 ms = 0.601 seconds
We can determine the magnitude of the electric current (I) using the following expression.
I = Q / t
I = 93.0 C / 0.601 s
I = 155 C/s
I = 155 A
The magnitude of the electric current is 155 Ampere.
