The balanced chemical equation for the combustion of acetic acid (CH3COOH) is: 2 CH3COOH + 4 O2 β 4 CO2 + 4 H2O
4 hydrogen atoms 4 nitrogen atoms 12 oxygen atoms
The coefficient that should be placed in front of PCl3 to balance the equation depends on the specific chemical equation you are referring to. Can you please provide the chemical equation?
4NaCl represents an equation because it shows the reaction of 4 moles of sodium chloride. It is not a molecule itself, but rather a representation of a chemical reaction involving 4 moles of NaCl.
The balanced chemical equation for the combustion of decane (C10H22) is: 2C10H22 + 31O2 -> 20CO2 + 22H2O
Let x the first number, y the second number. equation 1: x/y = 4 equation 2: x+y =20 equation 3: manipulate equation 1 ----> x=4y substitute equation 3 to equation 2: 4y+y=20 5y=20 y=20/5 y=4 solve for the value of x by substituting the value of y to equations 1 or 2: using equation 1: x/4=4 x=4*4 x=16 using equation 2: x+4=20 x=20-4 x=16 Therefore, the two (2) numbers are: 4 and 16.
The correct equation to solve 20 Γ· 4 x 4 + 8 equals 18 is as follows: First, divide 20 by 4 to get 5. Then, multiply 5 by 4 to get 20. Finally, add 8 to 20 to get the final answer of 28.
4x - 20 = -44x = 16x = 4
x=24
10 (-2) 5 (-4)
y=4
a number times 3 subtracted by 20 is -4 a x 3 - 20= -4
Points: (20, 18) and (35, 6) Slope: -4/5 Equation: y = -4/5x+34
Without an equality sign the terms given can't be considered to be an equation
If your equation is X+60=4(X) X=20 20+60=4(20) 80=80 Hope this helps.
It is an equation and the value of x is 8
2c+(12-4)=20 Simplify the expression in the parentheses first. 2c+8=20 Subtract 8 from both sides of the equation. 2c=12 Divide both sides of the equation by 2. c=6
