Answer:
Lewis structure is shown in the image below.
Explanation:
Acetate ion (CH₃COO⁻)
Valence electrons of carbon = 4
Valence electrons of oxygen = 6
Valence electrons of hydrogen = 1
Charge = 1 (Negative which means that the electrons are being added)
The total number of the valence electrons = 2(4) + 2(6) + 3(1) + 1 = 24
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,
The Lewis structure is shown in the image below.
They use natural resources like sunlight water they need soil water and sunlight to grow the stem should be pliable and firm and will have a green cast on the inside
It is A; <span>[He] 2s</span>²<span> 2p</span>² is another way to put it
The answer is C. The specific amount of energy emitted when electrons jump from excited states to the ground state refers to emission spectrum. The energy is emitted in the form of photons, and the photons have very specific wavelengths (energy) that correspond to the energy gaps between the excited states and the ground state. The specific wavelengths of light emitted are referred to as the "emission spectrum," and each element produces a different emission spectrum. Thus, this emitted energy can be used to identify the element from which your sample was taken.
Answer:
The element is carbon because the atomic mass of carbon is 12.
Explanation:
Abundance of x¹² = 98.9%
Abundance of x¹³ = 1.1%
Atomic mass of x¹² = 12 amu
Atomic mass of x¹³ = 13 amu
Average atomic mass = ?
Solution:
Average atomic mass of x= (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass of x = (12 ×98.9)+(13 ×1.1) /100
Average atomic mass of x = 1186.8 + 14.3 / 100
Average atomic mass of x = 1201.1/ 100
Average atomic mass of x = 12.01 amu.
The element is carbon because the atomic mass of carbon is 12.
