C, because the opposite would be + 2 and none of the ions have that charge
Answer:
50%
Step-by-step explanation:
its 50% it will land on head and 50% it will land on tails since there is only two sides on a coin
By putting in inputs(x) and outputs (y) to make ordered pairs, which go into a graph
Let x be the number of child admission tickets sold:
Child's ticket = x
There is a total of 145 tickets sold:
Adult = 145 - x
Total sales is $1020.80:
5.6x + 9.2(145 - x) = 1020.8
Solve for x:
5.6x + 9.2(145 - x) = 1020.8
5.6x + 1334 - 9.2x = 1020.8
3.6x = 313.2
x = 313.2 ÷ 3.6
x= 87
Answer: Number of child's ticket = 87
12.) This does not follow the rule of conservation because on the reactant side there is one Na and two Cl while the product side only has one Na and Cl. They are not equal and do not have the same number of atoms for the different elements. In the law of conservation matter cannot be created or destroyed and this does not follow the law.
13.) 2Na + Cl2 —> 2NaCl
Put a 2 in front of Na and a 2 in front of NaCl
