Which type of energy is thermal energy a form of? Hurry it's timed!

For elements (Br, Ca, Fe, Na, S, Si, and Xe) which of the following term(s) apply?

ioda

Answer:

Detail is given below.

Explanation:

Bromine: Br (Halogen and non metal)

Bromine is present in group 17 and it is called halogen.

All halogens are very reactive.

Calcium; Ca ( alkaline earth metal)

Calcium is present in group 2. It is alkaline earth metal.

It has two valance electrons.

Iron; Fe (Transition metal)

Iron is transition metal and also called d-block element.

Sodium: Na (Metal, main group element)

Sodium is metal and present in group one.

It has one valance electron.

Sulfur: S (non metal)

Sulfur is non metal. It is present in group 16.

It has six valance electrons.

Silicon: Si (metalloid)

Silicon is metalloid. It is present in group 14.

It has four valance electrons.

Xenon: Xe (Noble gas, gas at a room temperature)

it is noble gas. Xenon is present in group 18.

It is gas at a room temperature.

Answer:

1.15 atm

Explanation:

According to Dalton's law of partial pressures, the total pressure is the sum of all the partial pressures of the gases present in the mixture.

Therefore we have:

Total pressure = partial pressure of carbon monoxide + partial pressure of oxygen + partial pressure of carbon dioxide

We were given the following:

Total pressure = 2.45 atm

Pressure of oxygen = 0.65 atm

Pressure of carbon monoxide = x

Pressure of carbon dioxide = 0.65 atm

Therefore:

2.45 = x + 0.65 + 0.65

2.45 = x + 1.3

x = 2.45 - 1.3

x = 1.15 atm

Will has an aquarium with water, plants, and fish that eat the plants. It is sealed so no material can get in or out, and has gl

Aleks04 [339]

Answer:

The aquarium is covered and not in sunlight

Diminishing

Explanation:

The sun is the ultimate source of energy for all life and activities on earth. The aquarium is no exception.

Green plants manufactures food in the process of photosynthesis by combining carbon dioxide and water in the presence of sunlight.

This food provides all other lives with energy through the break down of energy held in carbon chains.

Is the aquarium now in sunlight or is it covered?

Here is a feeding relationship between plants and fish in a pond. The producer here is the plants. The consumer is the fish.

Using carbon dioxide and water, plants manufactures food. When the amount of carbon starts decreasing it shows that the aquarium is covered.

The source of dissolved carbon dioxide in water is the fish which gives off this gas as it respires. When the fish ceases to respire, it does not have enough food and might have died thereby decreasing carbon dioxide levels.

What is happening to the number of energy storage molecules in the plants and fish as a result?

The energy levels in both plant and fish will begin to reduce because the plant is unable to produce food which the fish depends on.

This will furnish a rapid decline in the energy available in these living organisms since the plants are not able to produce.

Why bond angle of H2O is maximum then OF2??

Nataly_w [17]

It's lone a little distinction (103 degrees versus 104 degrees in water), and I trust the standard rationalization is that since F is more electronegative than H, the electrons in the O-F bond invest more energy far from the O (and near the F) than the electrons in the O-H bond. That moves the powerful focal point of the unpleasant constrain between the bonding sets far from the O, and thus far from each other. So the shock between the bonding sets is marginally less, while the repugnance between the solitary matches on the O is the same - the outcome is the edge between the bonds is somewhat less.
