What is the value of k when 4x squared plus kx plus 9 equals 0?
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
How do you write algebraic expression in words for k plus 2.5?
k added to 2.5
What is 5r plus 20 equals 40?
It is a linear equation in the variable r.
What are the possible values of k in the quadratic equation x squared plus 5kx plus 2k equals 0 which has equal real roots?
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
What is the value of k when x2 plus 2kx plus 10x plus k2 plus 5 equals 0 has equal roots?
Equation: x^2 +2kx +10x +k^2 +5 = 0 Using the discriminant: (2k +10)^2 -4*1*(k^2 +5) = 0 Solving the discriminant: k = -2
Balanced equation for the production of potassium chloride?
2K(s) + Cl2(g) → 2KCl(s)
How do you balance BrCl --- Cl2 plus Br2?
To balance the chemical equation BrCl → Cl2 + Br2, you need to make sure that there are the same number of atoms of each element on both sides of the equation. Start by balancing the bromine atoms first, then balance the chlorine atoms. In this case, you would need to put a coefficient of 2 in front of BrCl and Cl2 to balance the equation, giving you the balanced equation: 2BrCl → Cl2 + Br2.
What is the chemical equation of potassium metal and chlorine gas combine to form potassium chloride?
The chemical equation for the reaction between potassium metal and chlorine gas to form potassium chloride is 2K(s) + Cl2(g) -> 2KCl(s).
Solve the equation k plus 3.4 equals 9?
k equals 5.6
Is K Br2 2KBr balanced?
No, the chemical equation K + Br2 → 2KBr is balanced in terms of atoms but not charges. To balance it completely, you need to ensure that the charges are equal on both sides of the reaction.
Write the point-slope equation of the line that goes through 5 3 with a slope of -12?
A line in the X-Y plane follows an equation y = (slope X x) plus a constant k. In this instances, 5 = [(-12)(3)] + k, or k = 5 + 36 = 41. Therefore, the equation is: y = -12x + 41.
How do you balance this equation K plus Br2--- KBR?
2 K + Br2 -> 2 Kbr
How do you balance the equation K plus H2O yields H2 plus KOH?
The balanced equation is 2K + 2H2O -> 2KOH + H2, balancing the atoms on both sides of the equation.
What is the value of k when 4x squared plus kx plus 9 equals 0?
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
What is k eq for the reaction 2HCI(g) H2(g) plus CI2(g)?
The equilibrium constant (K eq) for the reaction 2HCl(g) ⇌ H2(g) + Cl2(g) would be [H2][Cl2]/[HCl]^2, where the square brackets indicate the molar concentrations of the respective species at equilibrium.
How do you write k plus 2.5 in words?
A number, k, increased by two and a half.
How do you write algebraic expression in words for k plus 2.5?
k added to 2.5
