Joseph, a supervisor at H2O Chemicals Inc., needs to assess the behavior of 25 people, who constitute a large group of his subordinates. Which of the following methods combines ease of use with objectivity and a basis for providing feedback?

Answers

Answer 1
Answer:

Answer:

behavioral observation scale

Explanation:

According to my research on different methods for providing feedback, I can say that based on the information provided within the question Joseph should use a behavioral observation scale. This feedback method measures the level of performance and frequency of certain behaviors. In this situation this feedback method would be the easiest and most accurate method of providing feedback.

**Even though no answer choices were provided this method is the most used in these types of situations.**

A 5.00L balloon filled with 1.00 moles of O2 gas contains a total of how many liters?

Answers

To solve this we assume that the gas inside the balloon is an ideal gas and at STP. At standard temperature and pressure, it has been known that for 1 mol of a gas, the volume of this gas would be 22.4L. Therefore, the volume of O2 gas in the balloon would most likely be 22.4L.

If a compound has a molar mass of 180 g/mol and its empirical formula is CH2O, what is its molecular formula? CH2O C2H4O2 C6H12O6 C12H22O11

Answers

Its molecular formula : C₆H₁₂O₆

Further explanation  

The empirical formula(EF) is the smallest comparison of atoms of compound forming elements.  

A molecular formula(MF) is a formula that shows the number of atomic elements that make up a compound.  

(EF) n = MF

its empirical formula is CH₂O

CH₂O : 12+2+16=30

In the electron cloud model, electrons are said to be moving so fast that a person can _____.

Answers

Answer: Not determine their exact position.

Explanation:  In the electron cloud model, electrons are said to be moving so fast that a person cannot determine their exact position.

This phenomenon goes well off with the Heisnberg Uncertainity Principle (HUP)which states that the momentum (Δm) and position (Δx) of an obejct cannot be determined simultaneously at the same time.

The mathematical relation of HUP is -

                                      Δx Δm ≥ h/ 4π

where h = Planck's Constant

cannot describe their exact position.

What mass of chloride gas will react with 96.6g of sodium?

Answers

Molar mass :

Cl₂ =  71.0 g/mol        Na = 23.0 g/mol

2 Na + Cl = 2 NaCl

2 x 23 g Na -------> 71.0 g Cl₂
96.6 g Na ----------> ?

Mass Cl₂ = ( 96.6 x 71.0 ) / ( 2 x 23 )

Mass Cl₂ = 6858.6 / 46

= 149.1 g of Cl₂

What is the molarity of a solution that is made by adding 57.3 g of MgO to 500.0 mL of solutions

Answers

Answer:

The answer to your question is 2.84 M

Explanation:

Data

mass of MgO = 57.3 g

volume of the solution = 500 ml

Process

1.- Calculate the molar mass of MgO

MgO = 24.3 + 16 = 40.3 g

2.- Calculate the moles of MgO

                 40.3 g MgO ----------------- 1 mol

                  57.3 g MgO -----------------  x

                          x = (57.3 x 1) / 40.3

                          x = 1.42 moles

3.- Calculate the Molarity

Molarity = moles / volume (l)

Volume = 0.5 liters

-Substitution

Molarity = 1.42 / 0.5

-Result

Molarity = 2.84

Final answer:

The molarity of the solution is 2.84 M.

Explanation:

To find the molarity of the solution, we need to first calculate the number of moles of MgO and the volume of the solution.

First, we convert the mass of MgO to moles using its molar mass. The molar mass of MgO is 40.31 g/mol, so:

moles of MgO = mass of MgO / molar mass of MgO

moles of MgO = 57.3 g / 40.31 g/mol = 1.42 mol

Next, we convert the volume of the solution to liters:

volume of solution = 500.0 mL / 1000 mL/L = 0.500 L

Finally, we divide the number of moles of MgO by the volume of the solution to find the molarity:

molarity = moles of solute / volume of solution

molarity = 1.42 mol / 0.500 L = 2.84 M
