What is 2E plus 18?
The expression "2E plus 18" can be interpreted mathematically as (2E + 18). If (E) represents a variable or a number, the result will depend on the value of (E). For instance, if (E = 1), then (2E + 18 = 20). Without a specific value for (E), the expression remains (2E + 18).
What is 3c plus 4d-2e plus 2d plus 3e simplified?
To simplify the expression (3c + 4d - 2e + 2d + 3e), combine like terms. The terms with (d) are (4d + 2d = 6d), and the terms with (e) are (-2e + 3e = e). Thus, the simplified expression is (3c + 6d + e).
If y equals -4E-11x3 plus 2E-07x2 plus 9E-05x plus 0.062 what is x?
9E-05x
Cu---Cu plus 2 plus 2e- this equation above represents the type of reaction called?
oxidation
How do you solve 2e minus 12 equals 7e plus 8?
2e - 12 = 7e + 8Add 12 to both sides: 2e = 7e + 20 subtract 7e from both sides: -5e = 20 divide both sides by -5: e = -4
7f - 2e - 3f plus 4e?
It can be simplified to: 4f+2e

Zn2+ + 2e- <--> Zno -0.7618 V
Calculate the standard emf of a cell that uses the Mg Mg2 plus and Cu Cu2 plus half cell reactions at 25 degrees C?
Cu + Mg2 --------> Cu2 + Mg Cu --------------> Cu2 + 2e Mg2 + 2e --------> Mg Cu --------------> Cu2 + 2e (E = +0.35) Mg2 + 2e --------> Mg (E = -2.36V) +0.35 + (-2.36) = -2.01V --------------------------------------… Mg + Cu2 --------> Mg2 + Cu Mg --------------> Mg2 + 2e Cu2 + 2e --------> Cu Mg --------------> Mg2 + 2e (E = +2.36V) Cu2 + 2e --------> Mg (E = -0.35V) +2.36 + (-0.35) = +2.01V
What is 3c plus 4d-2e plus 2d plus 3e simplified?
To simplify the expression (3c + 4d - 2e + 2d + 3e), combine like terms. The terms with (d) are (4d + 2d = 6d), and the terms with (e) are (-2e + 3e = e). Thus, the simplified expression is (3c + 6d + e).
2e-7f-3e-f plus 6e plus 6f?
Simplified is 5e-2f.
If a is 5 b is 3 c is 10 d is 22 e is 20 and f is 4 what is 2e-bc divided by a?
2e-bc/a = 2 2e - bc / a = [2(20) - (3)(10)] / 5 = [40-30]/5 = 10/5
