Answer:

hydroxide and hydrogen

Explanation:

When a metal reacts with water, a metal hydroxide and hydrogen are formed. Sodium reacts vigorously with water.

Answer: Hydrogen Gas ( H2)

Explanation: When metals react with water they form hydrogen gas which actually react and start to burn and make squeaky pop noises.

Answer:

Basic or alkaline

Explanation:

ph 7 is neutral

below 7 is acidic

above 7 is basic or alkaline

Answer:

[tex]\boxed {\boxed {\sf Weak \ base}}[/tex]

Explanation:

The pH scale which classifies a solution's acidity or basicity.

We are given a reading of 8. This is above 7, but not much greater. Therefore, it could be classified as a weak base.

Answer: 6 moles of Carbon.

Explanation: One mole of Carbon is equal to 12 grams of Carbon, so you would divide 72 by 12 and the answer would be 6.

Answer:

Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects

The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe!

Gravitational force is the force that attracts to objects with mass. ... This forces tries to pull masses together, that is why attractive in nature. For example: When ball is thrown upwards it always come downwards after a certain height because the ball is pulled or attracted by the Earth's gravitation la force.

Answer:

c

Explanation:

x basic and metallic while y is acidic

The study of chemicals is called chemistry.

The correct answer is B.

The compound which has oxygen in it is called oxide. According to the question, the element is react with the acid and base.

The X only reacts with the acidic compound but not basic compound hence the element X is basic in nature. while Y only reacts with the basic compound, not X, hence the Y element is acidic in nature.

Therefore, the correct answer is B.

Answer:

0.00044 g/mL

Explanation:

First, 0.220 g of KIO₃ are dissolved in 50 mL, so the concentration at this point is:

Then 2.00 mL of this solution are added to 8.00 mL of water (final volume = 10.00 mL). We calculate the concentration of the resulting solution:

Finally, to this 10 mL solution, another 10.00 mL were added. Thus the KIO₃ (or IO₃⁻) concentration is:

Answer:

D. gain one electron

Explanation:

In order to become a chemically stable ion, a neutral atom of sodium will gain one electron. Therefore, the correct option is option D.

Chemical stability in chemistry refers to a chemical system's thermodynamic stability. When a system reaches its lowest energy state or in thermodynamic equilibrium with its surroundings, thermodynamic stability occurs.

It could be a spontaneous process when the total number of atoms or molecules in a given shape is conserved despite the fact that individual particles or atoms change forms. In order to become a chemically stable ion, a neutral atom of sodium will gain one electron.

Therefore, the correct option is option D.

Answer:

Explanation:

Answer:

Fe is the limiting reagent

Explanation:

In a chemical reaction, the limiting reactant, also known as the limiting reagent. Therefore, the correct option is option C.

In a chemical reaction, the limiting reactant, also known as the limiting reagent, controls how much product is produced. Calculating the percentage value of a reaction is achievable if the limiting reactant has been identified.

Because elements and compounds in an equilibrium chemical equation react in accordance with their mole ratios, there must be a limiting reactant. Therefore, when one of the reactants was present in a larger amount than the other and the mole ratio inside the balanced equation specifies that it takes 1 mole from each reactant to generate a product, the reactant existing in the lesser amount would be the limiting reactant.

4Al[tex]_2[/tex]O[tex]_3[/tex] + 9Fe [tex]\rightarrow[/tex] 3Fe[tex]_3[/tex]O[tex]_4[/tex] + 8A|

moles of Al[tex]_2[/tex]O[tex]_3[/tex] = 10.2 /101.96

                            =0.10moles
