Answer:

Best answer choice is "<u>Mass of the graduated cylinder with the liquid in </u><u>it</u> "

Explanation:

if they want to determine density of liquid they'll use D= m/v

  • they already have the volume (v)
  • now they just need the mass (m) of the liquid (BUT NOT OF THE CYLINDER) You'll want the LIQUID'S mass (m) ONLY
  • So <em>"</em><em>Mass of the graduated cylinder with the liquid in it</em><em>"</em> = Liquid's mass WITH the cylinder's mass ALSO, let's get rid of the cylinder's mass
  • now you get the liquid's mass by itself
  1. mass of graduated cylinder with liquid in it subtracted by the <em>Mass</em><em> </em><em>of</em><em> </em><em>empty</em><em> </em><em>graduated</em><em> </em><em>cylinder</em><em> </em><em>=</em><em> </em><em>(</em><em>m</em><em>)</em><em> </em>mass of liquid
  2. (m) mass of liquid ÷ (v) volume of liquid in the graduated cylinder = (D) Density
  3. So your answer will be "Mass of the graduated cylinder with the liquid in it"

About 55L of a gas in a flexible container is under a pressure of 3.2 atm and at a temperature of 520K. What is the new volume o
vampirchik [111]

Answer:

30.62 L

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 55 L

Initial pressure (P₁) = 3.2 atm

Initial temperature (T₁) = 520 K

Final temperature (T₂) = 760 K

Final pressure (P₂) = 8.4 atm

Final volume (V₂) =?

The final volume of the gas can be obtained as follow:

P₁V₁ / T₁ = P₂V₂ / T₂

3.2 × 55 / 520 = 8.4 × V₂ / 760

176 / 520 = 8.4 × V₂ / 760

Cross multiply

520 × 8.4 × V₂ = 176 × 760

4368 × V₂ = 133760

Divide both side by 4368

V₂ = 133760 / 4368

V₂ = 30.62 L

Therefore, the new volume of the gas is 30.62 L

Explain why 2-bromopropane reacts with sodium iodide in acetone over 104 times faster than bromocyclopropane. hint: examine the
Mama L [17]

Answer:-

The reaction of 2-bromopropane reacts with sodium iodide in acetone is an example of Sn2 reaction.

The I - attacks from backside to give the transition state for both.

If we compare the transition state for cyclobromopropane 2-bromopropane then we see in case of cyclobromopropane transition state, one of the H is very close to the incoming I -.

This results in steric strain and less stability of the transition state. Hence 2-bromopropane reacts with sodium iodide in acetone over 104 times faster than bromocyclopropane.

Create a food chain that shows the energy transfer from the sun to a grizzly bear. Include four transitions (arrows) in your foo
lidiya [134]

Sun⇒ Phytoplankton (Producer)⇒ Zooplankton (Primary consumer)⇒ Fish (Secondary consumer)⇒ Bear (Tertiary consumer).

  • A food chain is a sequence of transfer of food and energy when one organism is consumed by another organism.
  • A food chain is always unidirectional sequence.
  • In the provided food chain the sun is the source of energy required for the preparation of food by the phytoplankton that is an aquatic autotroph which will prepare its food by the process of photosynthesis.
  • The phytoplankton being producer of biomass is consumed by the zooplankton that is the primary consumer than the zooplankton will be consumed by the fish that is the secondary consumer and carnivore by origin and finally the fish will be consumed by the bear that is also carnivore and is tertiary consumer.
