Answer: ph scale
Explanation:
When baking soda is mixed with vinegar, bubbling is observed. This is because of a chemical reaction which involves the evolution of carbon dioxide gas. This reaction is used as an indicator of carbon dioxide.
What is an Indicator?An indicator in chemistry is any substance that gives a visible sign or indication of a chemical species by a change in color. An indicator is generally used to identify an acid or an alkali present in a solution.
Indicators are weak acids or alkalis that show a change in color as the concentration of hydrogen ions in solution changes. Commonly used chemical indicators include Litmus, turmeric, Methyl Orange, phenolphthalein, etc.
When baking soda is mixed with vinegar evolution of gas bubbles is observed. This gas when passed through lime water, the solution turns milky which confirms the presence of carbon dioxide in solution.
Therefore, chemical indicators can be used in identification of a chemical species.

Once again rocks and/or minerals
How could you determine whether
an unknown substance is a mineral?
Answer:
you can classify a mineral by its appearance and other properties. The presence of a mineral is defined by the color and luster, and the color of the powdered mineral is described by the band. Every mineral has a distinctive density. To compare the hardness of rocks, the Mohs Hardness Scale is used.
Explanation:
Answer:
Luster, hardness , colour , clevage and magnetism
Explanation:
1. Luster makes sure the light is reflected by the mineral.
2. On the 10-point Mohs scale, which is basically a scratch test, hardness is measured. Take an unidentified mineral and scrape it like a fingernail with an object of known hardness.
3. Zurite, for instance, is often a deep blue, and malachite is gray.
4. In minerals that appear to divide along one or more flat surfaces or planes, cleavage may be observed.
5. Magnetite, for instance, has a heavy pull that even weak magnets can draw. But there is only a poor attraction to other minerals, particularly chromite (a black oxide) and pyrrhotite (a bronze sulfide.)

sun
What effect does this arrangement have on the tidal range?
A. The tide is larger than normal because the gravitational forces of the sun and moon pull in the
same direction.
B. The tide is larger than normal because the gravitational forces of the sun and moon pull in
opposite directions.
C. The tide is smaller than normal because the gravitational forces of the sun and moon pull in
the same direction.
D. The tide is smaller than normal because the gravitational forces of the sun and moon pull in
opposite directions.
Answer:
A. because this is a spring tide.
Explanation: The sun and the moon are working together, their gravitational forces pull on the tides more. Your question said "The tide is larger than normal because the gravitational forces of the sun and moon pull in the same direction". They are working together to cause higher than normal tides.

Explanation:
Answer:
There are craters in the moon caused by asteroids and meteorites colliding with the moons surface
Explanation:
Unlike Earth it doesnt actually have a atmosphere to protect itself from being struck by the asteroids and or meteorites since our atmosphere pushes back anything entering if it can reach the inside of the object it could break it apart from the inside which is why many rockets are set up with protective layers to avoid being split apart during re entering.
