1) 7.15 * 10^6

since the exponent of the scientific notation is positive, move 6 places to the right.

so, <em>7.15 * 10^6 = 7150000</em>

2) 3.03 * 10^-8

Since the exponent of the scientific notation is negative, move the decimal point 8 places to the left.

so,<em> 3.03 * 10^-8 = 0.0000000303</em>

<em />

3)<em> </em>4.9 * 10^-1

since the exponent of the scientific notation is negative, move 1 decimal place to the left.

so,<em> 4.9 * 10^-1 = 0.49</em>

<em />

4) 2.886 * 10^5

since the exponent of the scientific notation is positive, move 5 decimal places to the right.

so,<em> 2.886 * 10^5 = 288600</em>

An electrolysis reaction is
Llana [10]

Answer:

the electrolysis reaction is a non- spontaneous reaction

Explanation:

Since electrons flow from it, the anode in an electrolytic cell is positive, while the cathode is negative when electrons flow into it. The device functions like a galvanic cell in that direction. In an electrolytic cell, an external voltage is applied and that is what causes a non spontaneous reaction
