What other small steps can we take to save water ?

Answer:

Beryllium metal is relatively unreactive at room temperature, particularly in its massive form. Magnesium is more electropositive than the amphoteric beryllium and reacts more readily with most of the nonmetals.

Explanation:

When it comes to the ease with which a positive ion or cation of the metal can form, beryllium is less reactive than magnesium.

The chemical element magnesium has the atomic number 12 and the letter Mg as its symbol. It is a glossy, gray metal with a low melting point, high chemical reactivity, and a low density. It only naturally occurs in mixtures with other elements, just like the other alkaline earth metals, and it almost always has an oxidation state of +2.

At room temperature, beryllium metal is largely non-reactive, especially in its massive form. Magnesium interacts more quickly with the majority of nonmetals because it is more electropositive than amphoteric beryllium.

Due to the electron being removed being in the 3-level rather than the 2-level and being further away from the nucleus's attraction, the first ionization energy of magnesium is lower than that of beryllium.

Thus, When it comes to the ease with which a positive ion or cation of the metal can form, beryllium is less reactive than magnesium.

Explanation:

They can move at rates of up to four inches (10 centimeters) per year, but most move much slower than that. Different parts of a plate move at different speeds. The plates move in different directions, colliding, moving away from, and sliding past one another. Most plates are made of both oceanic and continental crust.

HI and I-

Explanation:

Hello there!

In this case, according to the acid ionization of hydroiodic acid:

[tex]HI+H_2O\rightarrow I^-+H_3O^+[/tex]

Now, since the acid, HI, results in the conjugate base, I- and the base, H2O in the conjugate acid, H3O+, it is correct to assert that the acid-conjugate base pair is HI and I-

Best regards!

The acid-conjugate base pair in the reaction above is HI and I-. Details about conjugate base can be found below.

A conjugate base is the substance formed when an acid loses or donates its proton or hydrogen ion.

According to this question, the following reaction is given:

HI + H2O → H30+ + I-

Answer:

The volume at STP is 41.3mL

Explanation:

To solve this question we must find the volume using the combined gas law. The equation is:

P1V1 / T1 = P2V2 / T2

Where P is pressure, V volume and T absolute temperature of 1, initial state and 2, final state of the gas.

P1 = 718torr

V1 = 47.9mL

T1 = 26°C + 273.15 = 299.15K

P2 = 760torr at STP

V2 = ?

T2 = 273.15K at STP

Replacing:

718torr*47.9mL / 299.15K = 760torr*V2 / 273.15K

41.3mL = V2

Hydrogen-1 serves as the starting reactant in fusion reactions in the sun. This is due to the sun's composition, which is around 70% hydrogen and 28% helium with 2% heavier components. As a result, hydrogen-1 is both the most prevalent and most likely to be employed in a fusion process in the sun.

Two hydrogen-1 nuclei are fused together to create a helium-4 nucleus in the sun's fusion reaction, which releases energy in the process. This is the most significant energy source in the sun and is known as the proton-proton chain reaction.

When two hydrogen-1 nuclei collide to generate a deuterium nucleus, a gamma ray is released as a result, starting the reaction. Then, this deuterium nucleus strikes another.A helium-3 nucleus is created from a hydrogen-1 nucleus, which also produces a gamma ray.

The reaction is finally finished when two helium-3 nuclei meet to produce a helium-4 nucleus, producing two gamma rays in the process. Since hydrogen-1 is the most prevalent element in the sun and the element that is most likely to be employed in the proton-proton chain reaction, it is the first reactant for a fusion process in the sun.

A deuterium nucleus is created by the collision of two hydrogen-1 nuclei, which is followed by a sequence of further processes that ultimately result in the development of a helium-4 nucleus.
