Always is a pretty absolute word and since nothing is impossible I would say no. However, usually for the most part technology does follow science.
If you want to develop a technology, you need to understand the physical principals behind it such as dynamics,material behavior, etc. this all requires knowledge physics and chemistry.

Physicists during the 1800's were studying the theory to magnetic and electric fields and their interactions way before they were devices to create/observe this phenomenon esp. according to their theory.</span><span>

Water and salt are the products of a neutralization reaction.
An atom of carbon has 4 electrons in its outermost shell, which means that
<span>its ionic charge is 4+ or 4-
</span>Si is in same group as carbon so its also 4+ or 4-
Germanium is 4+.
Sn is also 2+ or 4+
Pb is usually +2
First, set up a proportion:
You have 2.00 g Carbon and 7.33 g of the total substance (find it by adding 2.00g C + 5.33 g O)
You have an unknown g carbon with 55.0 g o total substance.
So:
Multiply 2.00 by 55.0 and divide the answer by 7.33
You'll get 20.63...
When someone pees in the pool this can cause the PH to change and when you put other chemicals in the pool, this can also change the PH in the pool.
Mark brainliest if this helped!
