Answer:
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.
I should think that Yolanda should use litmus paper throughout the reaction as its color will tell when the mixture is neutral and therefore then, when she can stop adding either the hydrochloric acid or the sodium hydroxide or if one or the other needs to be added to make the solution approach neutral. Blue litmus paper stays blue in a neutral solution, but will turn red in an acidic solution.
Answer:
Precipitate
Explanation:
When a double displacement reaction occurs, the cations and anions switch partners, resulting in the formation of two new ionic compounds AD and CB, one of products is in the solid state and forms an insoluble ionic compound called a precipitate.
Your speed when your car hits a fixed object is 60 mph.
The given parameters:
- Your initial speed, v = 60 mph
<h3>What is relative velocity?</h3>
Relative velocity tells us how fast we are traveling from a fixed point or reference point.
- When travel at 60 mph in a car, you are moving at the same rate with the car.
- If you are not wearing a seat belt, when you hit a fixed object, you will move forward at the same rate as the car's speed.
Thus, we can conclude that your speed when your car hits a fixed object is 60 mph.
