Jose and Fran MUST follow specific safety procedures when heating water with a Bunsen burner. The safety procedures include
8_murik_8 [283]
The following are some common procedures that we should take action of when using a bunsen burner to ensure our safety:

1. Wear safety goggles. Tie up long hair and school ties if needed. This can lower the risk of catching on fire. Put a heatproof mat underneath the Bunsen burner, put a tripod and the beaker of water for heating on top of the burner.

2. Close the air hole. Before we start up the burner, the air hole must be closed or green flame (striking back) may occur 

3. light up a match or a lighter. Put it over the chimney. 

4. Turn on the gas tap, you should be able to see a yellow flame now. Remove the lighter or match and open the air hole. We should have a blue flame by now. 

5. the water should start to heat up. Never touch the hot beaker with bare hands.

6. When the water is heated up to the temperature they wanted to, it's time to close the air hole and turn off the gas tap. 

7. If they need to move the hot beaker, use heat protection gloves 

These should be the correct procedures that they should follow in order to heat the water safely. 

Hope it helps!

Outline three examples of cycles of inorganic nutrients. For each, outline the uses of the nutrients in living organisms, its me
Serggg [28]

The three examples of cycles of inorganic nutrients are Nitrogen, carbon and sulphur cycle.

Nitrogen is required to make amino acids and DNA in organisms. Carbon is the main component of glucose through which organism make energy, about 18 per-cent of the human body comprises carbon. Sulphur is an important constituent of some proteins, amino acids and enzyme cofactors.

Explanation:

The biogeochemical cycles like the nitrogen cycle are responsible for converting nitrogen into many chemical forms as nitrates, nitrites, ammonia. This process involves degrade decomposing animal and plant matter and naturally cleaning the environment also nitrites and nitrates become biofertilizers. The plants take nitrogen through their roots and in turn primary consumer in food chain ie. organisms consume the plant and eventually releases nitrogen as a waste material, dead and decaying body to the soil and cycle goes on.

In the carbon cycle the carbon is exchanged from the atmosphere to the organisms and then again to the environment. Plants perform photosynthesis by using carbon dioxide, primary consumer eats it and gets nutrition to perform cellular respiration, in turn, gets energy which gets dissipated and stored as biomass eventually in the course consumer die and replenish the soil with carbon. The Carbon emitted will keep cycling through air, water and soil.

The sulphur cycle involves the movement of sulphur between rocks, water and living beings and plants. Plants ( producers) absorb sulphur dissolved in water and animal consume these plants to replenish their sulphur requirement. And when organism die, sulphur enter the cycle again.

There will be a transfer of these inorganic nutrients to the trophic level in food chain.
