The balanced chemical equation for the combustion of acetic acid (CH3COOH) is: 2 CH3COOH + 4 O2 → 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?
Since there is no product, and only 1 reactant, it is not an equation, and thus, 4 molecules of sodium chloride
In excess O2. C10H12 + 13O2 => 10CO2 + 6H2O In limited O2: CO, C, CO2 and the equation cannot be balanced.
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 ÷ 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.
To solve the equation (-5m - 20 = 0), we first isolate (m) by adding 20 to both sides, resulting in (-5m = 20). Then, dividing both sides by -5 gives (m = -4). Since (-4) is indeed a negative number, the solution to the equation is negative.
To solve the equation, first calculate 100 divided by 4, which equals 25. Then, set up the equation: 20 + x = 25. Subtracting 20 from both sides gives x = 5. Therefore, the answer is 5.
