A new member of your team is visually impaired. He's having a hard time reading his computer screen. value diversity require computer usage. 12 Tell him that he might want to schedule an eye exam. Therefore, option C is correct.
What is value diversity ?Institutions and community members who value diversity do so in order to recognize the advantages of both their differences and commonalities. They make a deliberate effort to forge enduring connections between individuals and organizations with a broad membership.
When people's unique qualities, abilities, interests, and viewpoints are recognized and supported, they develop a stronger sense of self and health and achieve better results in their academic and professional endeavors.
Although diversity and inclusion are related ideas, they are not the same thing. Diversity has to do with representation or how something is put together. The degree to which the contributions, presence, and viewpoints of other groups of individuals are appreciated and incorporated into a setting is referred to as inclusion.
Thus, option C is correct.

Both propane and butane are used as gaseous fuels. Which compound produce more heat per gram burned? (mass of propane (C 3 H 3 )=44.1g/mol. mass of butane (C,H,0)=
58.1g/mol)(10pts)
(Hpropane-103.8kJ/mol.) (H propane-126.0kJ/mol)
Since the heat of combustion of butane is higher than that of propane, butane will produce more heat per gram when burned compared to propane.
The heat of combustion of a compound refers to the heat evolved when one mole of the compound is burnt under standard conditions. This heat of combustion increases from methane upwards.
Since the heat of combustion of alkanes increases according to increasing molar mass, butane will produce more heat per gram when burned compared to propane.

Consider a 0.241 M aqueous solution of sodium hydroxide, NaOH.
A. How many grams of NaOH are dissolved in 24.43 mL?
B. How many individual hydroxide ions (OH-) are found in 24.43 mL?
C. How many moles of sulfuric acid, H2SO4, are neutralized by 24.43 mL of 0.241 M NaOH(aq)?
Answer:
a. 0.2355052g
Explanation:
a)
1000ml of NaOH contain 0.241moles
24.43ml of NaOH contain (24.43*0.241)/1000 moles
= 0.00588763moles
Relative Molecular Mass of NaOH
= 1*23 + 1*16 + 1*1
= 40
1mole of NaOH weighs 40g
0.00588763moles weigh (0.00588763*40) g
= 0.2355052g
B)
NaOH -> Na+ + -OH
1 mole of NaOH dissociates to form 1 mole of -OH ions
1 mole of a substance contains 6.02*10^23 particles(atoms)
= 0.00588763 * 6.02 *10^23

How do ionic and molecular compounds behave in water?
Answer:
When ionic compounds dissolve in water they go through a process called dissociation, splitting into the ions that make them up. However, when you place covalent compounds in water, they typically do not dissolve but form a layer on top of the water.

Explanation:
The side of a cube is found to be 127.58 mm and its mass is found to be 7.3 kg. Determine the density of this cube in g/mL.
Answer:
3.5154 g/mL
Explanation:
You will need to use the equation Density = Mass/Volume. You are given mm(can be used to find volume) of a cube and kg(mass). Since your answer is in g and mL we should convert it to those sizes. First we want cm so we will divide the 127.58 mm to cm getting 12.758 cm. We want to cube it since we are finding the whole area of a cube( 12.758*12.758*12.758) which will equal 2076.58 cm^3. We know that 1 mL is equal to 1 cm^3, so we can take our 2076.58 cm^3 and label them as mL(which is what we want). Then we know that there are 1000g in 1 kg, so if we multiply the 7.3 kg, we get 7300g. Finally use the equation Density = Mass/Volume to get your answer. 7300g/2076.58mL = 3.5154 g/mL.

a. Anna's chemistry class is going to be experimenting with AgNO3 today, which
can stain hands and clothes. Anna is concerned about her jewelry, so as she
gets ready for school, she removes her gold (Au) ring andreplaces it with a
cheaper nickel (Ni) ring. Is this a good idea? Explain your answer. (3 points)
Answer:
No. While gold would not react with a silver nitrate solution, nickel would.
Explanation:
Refer to the metal reactivity series.
Reactivity: [tex]\text{Gold} < \text{Silver} < \text{Nickel}[/tex].
Gold is positioned after silver in the reactivity series, meaning that gold is typically less reactive than silver. Thus, gold would not react with a solution of silver ions to produce silver metal.
However, since nickel is positioned before silver in the reactivity series, it is expected that nickel would react with silver ions in this solution to produce silver metal.
Thus, if the silver nitrate solution comes into contact with the two rings, the nickel ring would likely react with the solution, the gold ring would not.
