In thermal cracking, high temperatures (typically in the range of 450°C to 750°C) and pressures (up to about 70 atmospheres) are used to break the large hydrocarbons into smaller ones. Thermal cracking gives mixtures of products containing high proportions of hydrocarbons with double bonds - alkenes.
Answer: The volume of
required is 25.0 ml
Explanation:
According to the neutralization law,
where,
= basicity
= 1
= molarity of
solution = 2.00 M
= volume of
solution = 50.0 ml
= acidity of
= 1
= molarity of
solution = 4.00 M
= volume of
solution = ?
Putting in the values we get:
Therefore, volume of
required is 25.0 ml
Francium is an element that melts at room temperature. Francium is a highly reactive element, and only contains one valence electron, which is very ironic in my opinion.
<u>Answer:</u> The amount of white phosphorus is 0.0199 moles
<u>Explanation:</u>
To calculate the number of moles, we use the equation:

We are given:
Given mass of white phosphorus = 2.478 g
Molar mass of white phosphorus = 124 g/mol
Putting values in above equation, we get:

Hence, the amount of white phosphorus is 0.0199 moles
