Answer:
0.013 M NaOH
Step-by-step explanation:
HCL + NaOH = NaCL + water
The mole ratio of acid and base is 1:1
Molarity is equal to the moles of solute divided by the liters of solution
Solute mole = 12.5 × 10^-3 × 0.3
= 0.003075
To neutralize 0.00375mol of HCl, 0.00375 mol of NaOH will be required. Since molarity is moles per liter, divide this amount of moles by the volume in liters:
Molarity = 0.00375/285 × 10^-3
Molarity = 0.0131 M
Answer:
When you reflect across the x-axis, the x coordinate stays the same. When you reflect across the y-axis, the x coordinate becomes opposite. When you reflect over the origin, both coordinates become opposite.
Step-by-step explanation:
When you look at the coordinate plane, the x-axis is horizontal (side to side) and the y-axis is vertical (up and down). If you reflect across the x-axis, then you are mirroring (flipping) the object over the horiontal line, which means your x value stays the same. If you reflect across the y-axis, you are mirroring (flipping) the object over the vertical line, which means your y value stays the same and the x value must become opposite. When you cross the origin, you are going diagonal across the coordinate plane, which means both the x and y values will become opposite.

Step-by-step explanation:
178.54-35.65=142.89
then you do 142.89/12.99=11

Solve for x.
mx+2nx=p
Factor out variable x.
x(m+2n)=p
Divide both sides by m+2n.
x(m+2n) / m+2n = p / m+2n
x=p / m+2n
