Determine two complex numbers, (a+bi) and (c+di), where a and d are irrational numbers and b and c are rational number
Dafna11 [192]

Answer:

The two complex numbers are \sqrt2 + 5i \text{ and } 6 + \sqrt5i

Explanation:

We have to form two complex numbers of the form

a + ib\\c + id

such that and d are irrational numbers and b and c are rational numbers.

We know that \sqrt2, \sqrt3 are irrational numbers.

5 and 6 are rational numbers.

We put

a = \sqrt2\\b = 5\\c = 6\\d = \sqrt5\\a+ib = \sqrt2 + 5i\\c + id = 6 + \sqrt5i

Thus, the two complex numbers are: \sqrt2 + 5i \text{ and } 6 + \sqrt5i

Round 0.0645 g to 2 significant figures
Hoochie [10]
The number of significant figures within a number are the amount digits that are required to specify a number to a certain degree of accuracy. In the number, 0.0645 g, the 6 is the most significant figure and 4 is the second most significant figure. Therefore, rounding to two significant figures yields 0.064g.

What is the total number of electrons shown in this Lewis structure of carbon dioxide? A. 8 B. 12 C. 16 D. 24
krek1111 [17]
Answer is 16
carbon valence = 4
oxygen valence = 6 but carbon dioxide have 2 oxygen so = 12
12 + 4 = 16
so carbon dioxide have 16 electron

Now they feel it is best to have you identify an unknown gas based on its properties. Suppose 0.508 g of a gas occupies a volume
pishuonlain [190]

Answer: Option (b) is the correct answer.

Explanation:

The given data is as follows.

             mass = 0.508 g,               Volume = 0.175 L

             Temperature = (25 + 273) K = 298 K,       P = 1 atm

As per the ideal gas law, PV = nRT.

where,  n = no. of moles = \frac{mass}{\text{molar mass}}

Hence, putting all the given values into the ideal gas equation as follows.

               PV = \frac{mass}{\text{molar mass}} \times RT            

           1 atm \times 0.175 L = \frac{0.508 g}{\text{molar mass}} \times 0.0821 L atm/ K mol \times 298 K  

                            = 71.02 g

As the molar mass of a chlorine atom is 35.4 g/mol and it exists as a gas. So, molar mass of Cl_{2} is 70.8 g/mol or 71 g/mol (approx).

Thus, we can conclude that the gas is most likely chlorine.
