In case of accidental contact with chemicals, how long should the eyes be flushed at the eyewash station

FromTheMoon [43]

Answer:

See the answer below

Explanation:

The duration of flushing the eyes at the eyewash station in case of accidental contact with chemicals depends of the nature of the chemical.

If the chemical is known to be a non-irritant or mild-irritant one, a 5-minute washing time is recommended as the first aid. before seeking the help of a physician,

For moderate to severe irritant chemicals, an immediate 15-20 minutes washing period is recommended before seeking further medical help.

For corrosive and strong alkalis chemicals, 30 and 60 minutes washing are recommended respectively before seeking the attention of a physician.

However, if the nature of the chemical is unknown, a minimum of 20-minutes washing is generally recommended as first aid before seeking immediate medical help.

Tarnish on copper is the compound CuO. A tarnished copper plate is placed in an aluminum pan of boiling water. When enough salt

Jet001 [13]

Answer: 2.00 V

Explanation:

The balanced redox reaction is:

$2Al+3Cu^{2+}\rightarrow 2Al^{3+}+3Cu$

Here Al undergoes oxidation by loss of electrons, thus act as anode. Copper undergoes reduction by gain of electrons and thus act as cathode.

$E^0=E^0_{cathode}- E^0_{anode}$

Where both $E^0$ are standard reduction potentials.

$Al^{3+}+3e^-\rightarrow Al$ $E^0_{[Al^{3+}/Al]}=-1.66V$

$Cu^{2+}+2e^-\rightarrow Cu$ $E^0_{[Cu^{2+}/Cu]}=0.340V$

$E^0=E^0_{[Cu^{2+}/Cu]}- E^0_{[Al^{3+}/Al]}$

$E^0=+0.34- (-1.66V)=2.00V$

Thus the standard cell potential is 2.00 V

Based on your knowledge of energy resources conservation, which of the following statements is true? a) Manufacturers can increa

Kruka [31]

Answer: Option (b) is the correct answer.

Explanation:

When useful energy is conserved then this conservation is known as energy conservation.

For example, when lights of a room are switched on where no one is sitting then on switching off the lights we are conserving wastage of electricity.

Thus, we can conclude that out of the given options, the statement energy resources can be conserved by turning off lights when they are not in use is true.

Which type of renewable energy creates electricity by using water currents to spin a turbine?

vovangra [49]

Answer:

Hydropower

Explanation:

I learn whenever Hydro is in a word it means water

Also in the question it is talking about water and wind, solar, nor Biomass has anything to do with water, so you can use the process of elimination and find you will only have Hydropower left.

Hope this helps
