12x+6 Solve for x
Answer:
x = 7
Explanation:
Simplifying
11x + 13 = 12x + 6
Reorder the terms:
13 + 11x = 12x + 6
Reorder the terms:
13 + 11x = 6 + 12x
Solving
13 + 11x = 6 + 12x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12x' to each side of the equation.
13 + 11x + -12x = 6 + 12x + -12x
Combine like terms: 11x + -12x = -1x
13 + -1x = 6 + 12x + -12x
Combine like terms: 12x + -12x = 0
13 + -1x = 6 + 0
13 + -1x = 6
Add '-13' to each side of the equation.
13 + -13 + -1x = 6 + -13
Combine like terms: 13 + -13 = 0
0 + -1x = 6 + -13
-1x = 6 + -13
Combine like terms: 6 + -13 = -7
-1x = -7
Divide each side by '-1'.
x = 7
Simplifying
x = 7
Answer:Simple and best practice solution for 11x+13=12x+6 equation. ... + 6 Reorder the terms: 13 + 11x = 6 + 12x Solving 13 + 11x = 6 + 12x Solving for variable 'x'.

The reactant surface area increases.
The reaction rate decreases.
The reaction is not affected at all.
The reaction stops completely.
Answer:
The increase in pressure alters the equilibrium of the reaction. In this case, the number of gaseous products in the reactant side is zero while the product side contains 1 gaseous product. The increase in pressure favors the side with less number of gaseous molecules which is the reactant side. Hence, the reaction rate decreases.
Explanation:
B. a solid must dissolve in a liquid

100% RIGHT
Explanation:
The balanced combustion reaction for butane is;
2C4H10 + 13O2 → 8CO2 + 10H2O
Molar mass of water = 18.02 g/mol
Molar mass of oxygen = 32 g/mol
2.46g H2O(1 mol H2O/18.02g)(13 mol O2/10 mol H2O)(32g O2/1 mol O2) = 5.68g O2
