Answer:

The density of the purple solution is _________________________.

The purple solution would form a layer __________________________.

Answer:

Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. Unlike the Earth, the Moon has no atmosphere to protect itself from impacting bodies.

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.

Taking into account the reaction stoichiometry, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.

In first place, the balanced reaction is:

2 H₂O → 2 H₂ + O₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The molar mass of the compounds is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

The theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.

The following rule of three can be applied: if by reaction stoichiometry 36 grams of water form 32 grams of oxygen, 29.2 grams of water form how much mass of oxygen?

[tex]mass of oxygen=\frac{29.2 grams of waterx32 grams of oxygen}{36 grams of water}[/tex]

mass of oxygen= 25.956 grams

Finally, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.

Answer: Yes he is successfull because he has released many books.

Explanation:

Answer:

list all the elements.

you need to find a number to multiply both sides to get the same result.

example: I said on the left side: 5×O2 which is 10. on the right side I do the same to get 10.

In order to do this I said: 4×H2O which is 8 H2,and 4 O.

I then said 3×CO2 which gives 3 C and 6 O2. 6+4=10.

Now Oxygen(O) is balanced. Do the same for the rest of the elements.

Explanation:

pls mark as brainliest thanks!

Let's use

Calculate atoms on both sides

On reactant side

On product

Now balance both sides by making atoms equal

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.)

I believe the answer is A. Radiation/ Radiant Heat.

Answer: A

Explanation:

The spot labelled as'A' in the image will turn into extrusive igneous rocks.

Igneous rocks are one of the three main rock types the other two including sedimentary and metamorphic rocks.These rocks are formed by cooling and solidification of lava or magma.

The magma is derived from partial melts in the planet's mantle or crust.Melting is caused by increase in temperature or decrease in pressure or even change in composition.Solidification occurs either below surface which is called as intrusive rocks or on the surface as extrusive rocks.

They are classified according to their texture,mode of occurrence,chemical composition,geometry and mineralogy of rock.The two important variables for classification are mineral composition and cooling history.

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.

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.
