Answer:Perform a series of experiments.

Explanation:

In the chemistry laboratory, unknown compounds are identified by a series of qualitative chemical tests called qualitative analysis. A well structured series of experiments with little quantities of the sample give us an idea of what the unknown sample may be. This is how an unknown compound may be identified in a chemical laboratory

A gas has a pressure of 853.0 millibars at a temperature of 29.0 °C. If the volume is unchanged but the temperature is increased
Nitella [24]

The new pressure of the gas that initially have a pressure of 853.0 millibars at a temperature of 29.0 °C is 1011.17 millibars. Details about pressure can be found below.

<h3>How to calculate pressure?</h3>

The pressure of a given gas can be calculated using the following formula:

P1/T1 = P2/T2

Where;

  • P1 = initial pressure = 853.0 millibars
  • P2 = final pressure = ?
  • T1 = initial temperature = 29°C + 273 = 302K
  • T2 = final temperature = 85°C + 273 = 358K

853/302 = P2/358

358 × 853 = 302P2

305374 = 302P2

P2 = 305374 ÷ 302

P2 = 1011.17 millibars

Therefore, the new pressure of the gas that initially have a pressure of 853.0 millibars at a temperature of 29.0 °C is 1011.17 millibars.

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.
