They're about the same, but a neutron has slightly more mass.
Answer:
Metallic.
Explanation:
Hello,
In this case, when nickel and tin bond, the difference in their electronegativities results:
Such difference, in addition to the fact that nickel is a transition metal and tin a metal, will suggest that the predominant type of bond for this substance is metallic as the attractive force between the conduction of electrons and positively charged metal ions is present.
Best regards.
Answer:
Below:
Explanation:
The Contact process If the temperature is increased, the equilibrium position moves in the direction of the endothermic reaction. This means it moves to the left in the Contact process. ... However, the rate of reaction is low at low temperatures. So, as in the Haber process, a compromise temperature of 450 °C is chosen.
Habar Process...
The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century.

<u>Answer:</u> The amount of element X remain after 40 years is 18.75 grams
<u>Explanation:</u>
We are given:
Total time period = 40 years
One half life = 10 years
Calculating the number of half lives,
To calculate the amount of element X after 4 half lives, we use the equation:
where,
a = amount of X after n-half lives
= initial amount of X = 300 g
n = number of half lives = 4
Putting values in above equation, we get:
Hence, the amount of element X remain after 40 years is 18.75 grams
What are the multiple choices?
