Answer:

A) C3H4

Explanation:

We have to remember that for each c<u>arbon we must have 4 bonds</u>. In a three-carbon alkene we will have 2 bonds for the <u>left carbon</u>, 4 bonds for the<u> central carbon</u> and 2 bonds for the <u>right carbon</u> (Figure 1). Therefore we have to add <u>2 hydrogens in the left carbon and 2 hydrogens for the right carbon</u>. Finally, if we count the number of carbons and hydrogens we will get C3H4.

Which series of atomic numbers represents the ordering of consecutive elements within the periodic table?
statuscvo [17]

Atomic number is same as the number of protons in the element which is further equal to the number of electrons. As the number of electrons increases in the element, the atomic number of the element also increases.

In periodic table, elements are arranged in the groups, and these groups are columns starting from 1 to 18, elements are arranged in increasing order of atomic number. Elements are placed with difference of one atomic number.

First four elements present in the periodic table is:

He atomic number is one (1).

H atomic number is two (2).

Li atomic number is three (3).

Be atomic number is four (4).

Thus, the series of atomic numbers that represents the ordering of consecutive elements within the periodic table is the last option - 1, 2, 3, 4...

If the fugacity of a pure component at the conditions of an ideal solution is 40 bar and its mole fraction is 0.4, what is its f
yaroslaw [1]

Answer : The fugacity in the solution is, 16 bar.

Explanation : Given,

Fugacity of a pure component = 40 bar

Mole fraction of component  = 0.4

Lewis-Randall rule : It states that in an ideal solution, the fugacity of a component is directly proportional to the mole fraction of the component in the solution.

Now we have to calculate the fugacity in the solution.

Formula used :

f_i=X_i\times f_i^o

where,

f_i = fugacity in the solution

f_i^o = fugacity of a pure component

X_1 = mole fraction of component

Now put all the give values in the above formula, we get:

f_i=0.4\times 40\text{ bar}

f_i=16\text{ bar}

Therefore, the fugacity in the solution is, 16 bar.
