Answer:

0.5 g/mL----- float

1.0 g/mL---- float

2.0 g/mL-----sink

Explanation:

Those objects will float whose density is less or equal to water density due to lower mass while those object will sink whose density is greater than water because the mass of the object is greater than water. So the density of the object i. e. 0.5 g/mL and 1.0 g/mL will float in the liquid because its density is lower than water which is 1 g/mL while the density of an object i. e. 2.0 g/mL is denser than water so it will sink.

Indicate whether the pair of structures shown represent stereoisomers, constitutional isomers, different conformations of the sa
aalyn [17]

The structures shown are examples of Constitutional Isomer.

In Chemistry, an isomer refers to a molecule that is similar to another but has differences. These differences can be:

  • A difference in the constitution: The molecules have the same formula but the connectivities between elements or arrangement is different.
  • Arrangement in space: The molecules have the same formula and connectivity, but they look different to do an arrangement in space of a position.

The molecules shown have the same formula because the elements in each pair are the same. However, the way these elements are connected is slightly different because the Br and the CH3 are connected to different carbons.

Based on this, the difference is the connectivity or constitution, and therefore these are constitutional isomers.

The body metabolizes glucose (C6H12O6) by burning it with oxygen to produce carbon dioxide, water and energy. If 3 moles of gluc
zhannawk [14.2K]

Answer: 18g

Explanation:

1 mle of glucose combusts to give 6moles of CO2 and 6moles of H2O

C6H12O6 + 6O2-------- 6CO2 + 6H2O at STP.

Multiplying 6 by 3 moles we have 18 g of CO2

Why do you think there are different stars in each nighttime section of the artifact?
chubhunter [2.5K]

A gas is contained in a thick-walled balloon. When the pressure changes from 39.1 bar to 87.0 bar the volume changes from blank
lidiya [134]

Answer: -

1.34 L

Explanation: -

Initial Pressure P 1 = 39.1 bar

Initial Temperature T 1 = 643 K

Let the initial volume be V 1.

Final pressure P 2 = 87.0 bar

Final temperature T 2 = 525 K.

Final volume V 2 = 0.492 L

Using the equation

\frac{P1 V 1}{T1} = \frac{P 2 V 2}{T2}

V 1 = \frac{P2 V2 T1}{P 1 T2}

Plugging in the values

We have

V 1 = 87 bar x 0.492 L x 643 K / (39.1 bar x 525 K)

= 1.34 L

Thus, a gas is contained in a thick-walled balloon. When the pressure changes from 39.1 bar to 87.0 bar the volume changes from 1.34 L to 0.492L and the temperature changes from 643K to 525K
