Answer:
option B will he the statement of this equation
Answer:
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
balanced equation : 4 Al +3O2 → 2 ALO3
Step-by-step explanation:
Al + O2 → Al2O3
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
but then you have to deal with the amount of O from both sides, we need to find the least common multiple between 2 and 3 which is 6
the best thing to balance the equation is to multiply O2 by 3 and O3 by2, then deal with the amount of AL which is 4 on the other side. last step is to multiply AL by 4 to balance the equation.
Answer:
Option D.
Step-by-step explanation:
A reflection is a mirror image across the a line of reflection. The image will be perpendicular to the line of reflection and equal distance from it as the pre-image is too. This means that point G will move horizontally across the y-axis the same distance it is currently from the y-axis. It is 2 units away from the y-axis so G' will be 2 units on the other side or -2. This makes G' (-2,2). Notice this is the same coordinates of G only multiplied by -1. When reflecting a shape across the y-axis, the x-coordinates of the points are multiplied by -1.
So G (2,2) becomes (-2,2).
So F (-2,-1) becomes (2,-1).
So H (4,-3) becomes (-4,-3).
