Answer:
The answer to your question is: 2.75 x 10 ²¹ atoms
Explanation:
Data
H₃PO₄
mass = 0.1488 g
MW H₃PO₄ = 3 + 31 + (16 x 4) = 98g
98 g of H₃PO₄ ------------------ 3 g of H₂
0.1488 g H₃PO₄ --------------- x
x = 0.0046 g of H₂
1 g of H₂ ------------------- 6.023 x 10²³ atoms
0.0046 g of H₂ -------------- x
x = (0.0046 x 6.023 x 10²³) / 1
x = 2.75 x 10 ²¹ atoms
Answer:
The second quantum number, known as the angular or orbital quantum number, describes the subshell and gives the magnitude of the orbital angular momentum through the relation. In chemistry and spectroscopy, ℓ = 0 is called an s orbital, ℓ = 1 a p orbital, ℓ = 2 a d orbital, and ℓ = 3 an f orbital.
<h3>Answer:</h3>
Heterogeneous mixture
<h3>Explanation:</h3>
The easiest way of defining Heterogeneous mixture is that it is mixture in which the composition of components is not uniform. Also, the substances present in this mixture are visible to naked eye. In fact, the size of solutes in heterogeneous mixture is greater as compared to that the sizes of solutes in homogeneous solutions. hence in salad dressing the oil, vinegar and spices are all visible and can easily be seen by naked eye.
Answer:
Explanation:
Electrons have negative charge and they orbit around the nucleus.
Protons have positive charge and are inside the nucleus
Neutrons have neutral charge they are also inside the nucleus
the nucleus is the middle of the atom
the electron cloud is a cloud which the electrons travel around
Then why did you ask ??...........
