Which of the following is a nonelectrolyte? Please state why or why not for each. a) NaOHb) HNO3c) C2H6O (ethanol)d) KFe) CH3COOH (acetic acid) The correct answer and explanation is : The correct answer is C2H6O (ethanol). Here’s why: Explanation of each compound: Conclusion: Ethanol (C2H6O) is the only nonelectrolyte in the list because it

IF Y=3x-100 and x=50 then the value of y is The correct answer and explanation is : To solve the equation ( Y = 3x – 100 ) for ( x = 50 ), we will substitute the value of ( x ) into the equation and calculate the value of ( Y ). Step

The specific weight of a fluid is 11 200 N=m3. Calculate the mass contained in 2 m3 (a) Using the standard gravity. (b) Using the maximum gravity on the earth’s surface. (c) Using the minimum gravity on the earth’s surface. The correct answer and explanation is : To calculate the mass contained in 2 m³

If the specific volume of a certain gas is 0.7848 m3/kg, what is its specific weight? The correct answer and explanation is : To calculate the specific weight of a gas, we can use the relationship between specific volume and specific weight. Formula: [\gamma = \frac{g}{v}]where: Alternatively, the specific weight can be calculated using the

In the Immediate Environment, the competition has no effect on consumers. True False The correct answer and explanation is : False In the context of economics and consumer behavior, the statement that “the competition has no effect on consumers” is false. Competition plays a crucial role in shaping consumer choices, behavior, and overall market dynamics,

Given the following information, what would efficiency be?Effective capacity = 80 units per dayDesign capacity = 100 units per dayUtilization 48 percent80 percent35 percent48 percent20 percent60 percent The correct answer and explanation is : To calculate efficiency, we need to understand the following terms: Now, efficiency is calculated using the formula: [\text{Efficiency} = \left( \frac{\text{Actual

Show a Lewis structure of an isomer of urea that still has both Ns and the 0 bonded to the C and has formal charges of zero at all atoms. The correct answer and explanation is : The isomer of urea you are referring to is cyanamide (H2NCN), which is an isomer of urea but

The results of a survey of people who bought either a computer or a laptop from two brands A and B are shown in the table below. A. Fill the mission data in the table (5 Marks) If a person is selected at random from the group, what is the probability that heishe B. Bought brand B? (5 Marks)

Show a Lewis structure for urea. CH4N2O. Both N’s and the O are bonded to the C. The H’s are bonded to the N’s. None of the atoms has a formal charge. The correct answer and explanation is : The Lewis structure for urea (CH₄N₂O) can be drawn by considering the bonding and electron distribution
