Gwar [14]2 years ago

Answer:

At a constant pressure the production of heat will be 25.9 KJ.

Explanation:

The heat produces at constant pressure will be more as compared to the heat produced at constant volume because,

At a constant pressure there is some work done and heat is used in this process. All the heat is not going to change the temperature. while,

At constant volume there is no work done and all the heat is going to change the temperature. In other words we can say that it take less heat to produce the temperature change at  a constant volume as compared to at constant pressure.

Cv ∠ Cp

So, when 1.5 g of fuel is burn at constant pressure it will produce 25.9 KJ. while at constant volume it will produce 23.3 KJ.

Both the acetamido (-NHCOCH3) and bromo (-Br) substituents are ortho, para directors. Even though the acetamido group is much la
sweet [91]

Answer:

Explanation has been given below

Explanation:

  • Attachment of -Cl group at ortho position to acetamido group can be explained in terms of hydrogen bonding formation.
  • A hydrogen bonding can be formed between proton attached with N atom in acetamido group and Cl atom at ortho position. This leads to a formation of a stable 5-membered ring structure.
  • Hence ortho substitution by Cl is favorable process.
  • There is no hydrogen bonding possible between Br and Cl atom in ortho position. Therefore Cl prefers para position to avoid steric hindrance.
  • Structure of hydrogen bonded structure has been shown below.

Can someone please help me with this?--20 pts!
katrin2010 [14]

Answer:

Compound B is ionic. The electronegativity difference is 2.2, which can be determined by subtracting the electronegativity of Element Y from that of Element Z. Electronegativity differences greater than 1.7 indicate ionic bonds.

Hope that helps.

Gasoline has a density of 0.7197 grams per milliliter. Calculate the mass, in grams, of a sample of gasoline with a volume of 48
barxatty [35]

Answer:

34.9103 or 34.9 g

Explanation:

Remember Density is a broken heart: m/v.

In this scenario (Let x = # of grams in the sample of gasoline),

D = 0.7198 g/mL = x g / 48.5 mL

So,

(0.7198 g/mL) * (48.5 mL) = x g

x g = 34.9103 = 34.9 g (Accounting for Significant Figures)
