Answer:
= C3H4N
Explanation:
We are given; 90 grams carbon, 11 grams hydrogen, and 35 grams nitrogen.
We first calculate the number of moles of each element.
Carbon = 90g/12 g/mol
= 7.5 moles
Hydrogen = 11 g/ 1 g/mol
= 11 moles
Nitrogen = 35 g/ 14 g/mol
= 2.5 moles
The we get the mole ratio of the elements;
= 7.5/2.5 : 11/2.5 : 2.5 /2.5
= 3 : 4.4 : 1
= 3 : 4 : 1
Therefore;
The empirical formula will be; C3H4N
Answer:
Protons= 17, Electrons= 17, Neutrons= 18
Explanation:
The atomic number (Z) corresponds to the number of electrons that is equal to the number of protons (17). The mass number (A) corresponds to the sum of protons and neutrons present in the nucleus (35). Therefore, we calculate the number of neutrons: 35-17 = 18
Answer:
THE ANSWERS IS A MODERN ANSWERS IS THE BIOLOGY WAY
Explanation:
Answer:
Y
Explanation:
Okay so, the least amount of potential energy translates to the most amount of kinetic energy. Potential energy is normally higher at the top, top of a roller coaster, building, etc. And so Y or W must be the answer. Y has less potential energy since it is longer. There is more time for the kinetic energy to stay as kinetic energy before reaching the top and transforming into potential energy. You could choose W but I don't think it's the right answer. Hope this helps!
