In the electrolytic cell, depending on the polarity of the battery, either a more vigorous reaction (though the same as the voltaic cell) would occur, or the reverse would.
Hi! Science stands for “Systematic Comprehensive Investigation and Exploration of Nature Causes and Effects”.
What is science?
Science is the systematic study of the structure and behavior of the physical natural world. It is also use for experience or can say it is an experience. Scientists are people who test science/experiments for the worlds. Science really is just the study of the nature. Science use math em empathic and logic, which are sometimes called “formal science”.
Answer:
A computer's ability to perform so many calculations in a very short time affects how people communicate by stopping them from talking actually. We no longer talk verbally. We don't go out and socialize, we always talk from the phone or text. We have lost our inner touch with talking.
Explanation:
B. the tilt of the Earth on it's axis
The moon affects the tides by it's gravitational pull on Earth. So the moon has no affect on the earth's seasons. The distance from earth from the sun only affects the ability of Earth to sustain liquid water because earth is in something scientists like to call the "Goldilocks Zone" This has no affect on the seasons. However, the angle at which the sun's light hit the earth does effect seasonal changes and it's tilt does change.

Answer:</h3>
Lead-205 (Pb-205)
<h3>
Explanation:</h3>
<u>We are given;</u>
We are supposed to identify its product after an alpha decay;
- Polonium-209 has a mass number of 209 and an atomic number of 84.
- When an element undergoes an alpha decay, the mass number decreases by 4 while the atomic number decreases by 2.
- Therefore, when Po-209 undergoes alpha decay it results to the formation of a product with a mass number of 205 and atomic number of 82.
- The product from this decay is Pb-205, because Pb-205 has a mass number of 205 and atomic number 82.
- The equation for the decay is;
²⁰⁹₈₄Po → ²⁰⁵₈₂Pb + ⁴₂He
- Note; An alpha particle is represented by a helium nucleus, ⁴₂He.
