Question 10
creativ13 [48]

Answer:

M₂  = 0.08 M

Explanation:

Given data:

Initial volume = 25.0 mL

Initial molarity = 0.500 M

Final volume = 150.0 mL

Final molarity = ?

Solution:

Formula:

M₁V₁          =     M₂V₂

0.500 M × 25.0 mL = M₂ ×  150.0 mL

M₂  = 0.500 M × 25.0 mL /   150.0 mL

M₂  = 12.5 M.mL /150.0 mL

M₂  = 0.08 M

Independent Assessment 1 Directions: Choose the correct concept about the occurrence of an earthquake and a volcanic eruption. W
Julli [10]

Volcanoes and earthquakes occur due to movement of the Earth's tectonic plates.

<h3>How volcanoes and earthquake occur?</h3>

Both volcanoes and earthquakes occur due to movement of the Earth's tectonic plates. They both occurs due to the heat and energy that is releasing from the Earth's core. Earthquakes can increase or fastens the volcanic eruptions through severe movement of tectonic plates.

Volcanoes eruption occurs when molten rock called magma rises to the surface. Magma is formed when the earth's mantle part melts due to higher temperature.

So we can conclude that volcanoes and earthquakes occur due to movement of the Earth's tectonic plates.
