What is the most reactive metal

Chemistry
1 answer:
ohaa [14]3 years ago
6 0


Some people think its francium and some people believe it is either sodium or potassium.

Some people believe that the most reactive element is francium because the larger the atom, the easier it is to get rid of the valence electrons and the easier it is to react with other atoms. so now if you look at the periodic table, francium has the largest radius and so that's why some people think its francium. but in my opinion, Francium AND Cesium.

What is true of intercellular signals that do not go through direct connections between cells, such as plasmodesmata?
Ronch [10]

I believe that what happens here is that when those cells carrying those intercellular signals do no pass through the connections, actually the signal is passed through or are transferred to adjacent cells for signal transmission, hence the answer is:

Upper n subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3 (g). At equilibrium, th
artcher [175]

Answer:

The <u>equilibrium constant</u> is:

              k_c=0.0030M^{-2}

Explanation:

The correct equation is:

  •   N₂(g)    +    3H₂(g)    ⇄    2NH₃(g)

Thus, with the equilibrium concentrations you can calculate the equilibrium constant, Kc.

The equation for the equilibrium constant is:

         k_c=\dfrac{[NH_3]^2}{[N_2]\cdot [H_2]^3}

Substituting:

        k_c=\dfrac{(0.105M)^2}{(1.1M)\cdot (1.50M)^3}

         k_c=0.0030M^{-2}

What is the value of k, at 25 degrees Celsius
Dimas [21]
<h3>Answer:</h3>

298.15 K

<h3>Explanation:</h3>

W e are supposed to calculate the Value of K at 25°C

Assuming the value of K represent K, the question wants us to convert  degree Celsius to Kelvin.

  • To convert degrees Celsius to kelvin scale, we use the relationship;
  • Kelvin (K) = Degrees Celsius + 273.15 ; 273.5 is a constant
  • That is, to convert temperature from °C to Kelvin we add a constant of 273.15 to the °C given.

In this case;

Temperature is 273.15 °c

Thus, to Kelvin scale temperature will be;

= 25°C + 273.15

= 298.15 K

Therefore, the value of K, at 25°C is 298.15 K

Answer:

The answer to your question is: Nuclear fussion

Explanation:

In Chemistry there are 2 nuclear processes:

Nuclear fission: is the process in which the nucleus of a radiactive element splits into two smaller nucleus, or two elements woth lower atomic number.

Nuclear fussion, is a reaction is which to small nucleus combine to form a heavier element.
