Find your element on the periodic table. Locate the element’s atomic number.
Determine the number of electrons. Look for the atomic mass of the element. Subtract (-) the atomic number from the atomic mass
Answer:
The answer to your problem is
B) river water stored in a reservoir flows down a channel in a dam, turning a turbine as it passes. the turbine is connected to a generator that produces electricity, and then the water continues downstream

Explanation:
Answer:
The amount of gas is what I came up with
<u>Ans: P = 22.5% and Cl = 77.5%</u>
<u></u>
<u>Given:</u>
Total Mass of sample containing P and Cl = 50.51 g
Mass of P produced = 11.39 g
<u>To determine:</u>
Mass % of P and Cl
<u>Explanation:</u>
Mass % of a given element in a total mass is generally expressed as:
Mass % of element = [mass of element/total mass]*100
Here,
Total mass = mass of P + mass of Cl
mass of Cl = Total - mass of P = 50.51-11.39 = 39.12 g
% P = [11.39/50.51]*100 = 22.5%
%Cl = [39.12/50.51]*100 = 77.5%
Answer:
D. Electrons: Negative.
Explanation:
Hello, happy to help you today!
In this case, by considering the Bohr's atomic model in which atom is composed by a nuclei containing both protons and neutrons which are positively and neutrally charged respectively and surrounding electrons assembled in orbits or levels of energy which are negatively charged in order to provide a balance to the atom, the correct statement is: D. Electrons: Negative. Also consider the Bohr's model on the attached picture.
My best regards to you!
