Answer:
The second transformation is a rotation around (point) L.
Explanation:
Generally, a rigid transformation is used to change only the position of a figure while the shape remains the same. In order to map a triangle (ΔJKL) to another triangle (ΔMNQ), two rigid transformations were employed. In the first transformation, the vertex L was mapped to the vertex Q. Therefore, the second transformation will definitely involve the rotation around (point) L. This will complete the two rigid transformations.

Answer:
3 Ca(OH)2 + 2 K3PO4 ---> Ca3(PO4)2 + 6 KOH
Explanation:
Just balance each atom on both sides.
Answer:
2 51 × 10^-5mol/L
Explanation:
The concentration of hydrogen ions can be calculated using the formula below :
pH = -log [H+]
pH = 4.6
[H+] = ?
[H+] = Antilog (-4.6)
[H+] = 2 51 × 10^-5mol/L
Answer:
96 grams
Explanation:
Density = mass / volume Multiply both sides by the volume
density * volume = mass
mass = 8 g / cm^3 * 12 cm^3
mass = 96 grams
