Is it necessary
Can I get it cheaper elsewhere
Will it last a while
These are just 3 I came up with. I do not know if they are what your teacher would have put.
Step 1: Simplify both sides of the equation.
7−3x=3(3−x)−2
7+−3x=(3)(3)+(3)(−x)+−2(Distribute)
7+−3x=9+−3x+−2
−3x+7=(−3x)+(9+−2)(Combine Like Terms)
−3x+7=−3x+7
−3x+7=−3x+7
Step 2: Add 3x to both sides.
−3x+7+3x=−3x+7+3x
7=7
Step 3: Subtract 7 from both sides.
7−7=7−7
0=0
So all real numbers
Answer:
Explanation:
Hello,
In this case, based on the given rewritten reaction:
The stoichiometry leads to the following theoretical moles of oxygen:
As sodium and hydrogen as a 2 to 1 molar relationship.
Step-by-step explanation:
The answer is 4. You take 2 and divide it by 0.5.
