I need help! And can someone explain to me! Not just answering the question!

Yes it is balanced. This is because the 2 (coefficient) in front of the Magnesium means there are a total of 2 magnesium atoms. The O2 means there is also 2 oxygen atoms. You can only change coefficients when balancing equations. If an element doesn’t have a coefficient before, there is only one. There is no need to change O2 coefficient since the little 2 means there are already two oxygen. This equation is balanced already due to the elements equally adding up to 2 of each in the end. This process is called synthesis.

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
