A deep teeth cleaning can remove a buildup of plaque and tartar on your teeth, reducing gum inflammation and improving gum health. Plaque is a sticky film that forms on teeth. It contains bacteria and develops when food particles mix with saliva. You can remove plaque, which collects on teeth daily, by brushing your teeth.

Answer: Stomata allow CO2 to diffuse and can close to minimize water loss. Liverwort pores allow gas exchange and cannot be closed if conditions become dry.

Explanation:

In the kingdom plantae, the liverworts belong to the phylum Bryophyta. A liverwort has a simple structure, ribbon- like body, that lies flat on the ground and is attached to the soil by many rhizoids. They grow in damp places on land and are capable of controlling gaseous exchange through the pores found on their leaf surfaces. Liverworts are non- vascular plants therefore they lack stomata. Unlike the stomata of vascular plants which close in dry weather, the air pores of liverworts remain open all the time. Liverworts cannot control their water loss (transpiration) through the pores.

Stomata are found in the epidermal layer of leaves in vascular plants. The opening and closing of stomata, through the help of the guard cells, control the flow of gases in and out of the leaves. This control is necessary to prevent excessive loss of water as vapour from the plant body throughout transpiration. Changes in the solute concentration of the guard cells cause water to flow in and out of the leaf epidermal cells.

Therefore, to COMPARE the stomata with pores of liverworts, they both allow gaseous exchange but in CONTRAST, stomata has the ability to control water loss as it can open and close while the pores lack this ability.

Answer:

1. 58.5g/mol

2. 261g/mol

3. 158g/mol

4. 71g/mol

5. 44g/mol

Explanation:

The molar mass of a compound is the total mass of the sum of masses of all individual elements that make up the compound. First, we need to know the atomic masses of each element in a compound.

1. NaCl

Where; Na = 23, and Cl = 35.5

Molar mass of NaCl = 23 + 35.5

= 58.5g/mol

2. Ba(NO3)2:

Where; Ba = 137, N = 14, O = 16

Molar mass of Ba(NO3)2: 137 + {14 + 16(3)} 2

137 + (14 + 48)2

137 + (62)2

137 + 124

= 261g/mol

3. K(MnO4)

Where; K = 39, Mn = 55, O = 16

Molar mass of KMnO4 = 39 + 55 + 16(4)

= 94 + 64

= 158g/mol

4. Cl2

Where; Cl = 35.5

Molar mass of Cl2 = 35.5(2)

= 71g/mol

5. CO2

Where; C = 12, O = 16

Molar Mass of CO2 = 12 + 16(2)

= 12 + 32

= 44g/mol

Los orbitales híbridos se obtienen mediante una combinación de orbitales atómicos.

En un átomo de carbono con hibridación sp3, el átomo de carbono es tetraédrico con un ángulo de enlace de 109,5 grados. Se pueden unir cuatro enlaces simples al átomo de carbono. Se pueden unir un total de cuatro átomos al carbono. Se puede unir un total de cuatro átomos al carbono, lo que ocurre en alcanos como el metano

Para un átomo de carbono con hibridación sp2, hay dos enlaces dobles y dos enlaces simples unidos al átomo de carbono que tiene una geometría plana trigonal con un ángulo de enlace de 120 grados. Se pueden unir un total de dos átomos al carbono. Se pueden unir un total de dos átomos al carbono. Esto ocurre en alquenos como el eteno.

Un átomo de carbono con hibridación sp tiene un ángulo de enlace de 180 grados y tiene una geometría lineal con un enlace triple y un enlace sencillo. Solo se puede unir un átomo al carbono. Esto ocurre en alquinos como el etino.

Answer:

e. 327/227

Explanation:

This is the correct standard pressure.

Answer:

Explanation:

The main reason is because they have different energy in the photon and different wavelength.

In the electromagnetic radiations, radio waves have little energetic photons, micro wave have more that radio waves, the visible light, ultraviolet x Ray's, and gamma Ray's have more energetic photons. They have different wavelength. The shorter the wavelength, the higher the frequency. Wavelength decreases while frequencies increases.

Answer:

Explanation:

Decreasing the volume of a contained gas will increase its pressure, and increasing its volume will decrease its pressure. In fact, if the volume increases by a certain factor, the pressure decreases by the same factor, and vice versa. Volume-pressure data for an air sample at room temperature are graphed in Figure 5.

Because the volume has decreased, the particles will collide more frequently with the walls of the container. ... When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume. This is shown by the following equation - which is often called Boyle's law.

The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles. Decreasing the temperature would have the opposite effect, and the pressure of an enclosed gas would decrease.

For a fixed mass of gas at constant temperature, the volume is inversely proportional to the pressure. That means that, for example, if you double the pressure, you will halve the volume. If you increase the pressure 10 times, the volume will decrease 10 times.

Temperature, pressure, volume and the amount of a gas influence its pressure.

Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.

i really hope some of this helped i would put more but its a lot too type

Answer: The volume of the gas is 1.98 L.

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

where,

[tex]V_1\text{ and }T_1[/tex] are the initial volume and temperature of the gas.

[tex]V_2\text{ and }T_2[/tex] are the final volume and temperature of the gas.

We are given:

[tex]V_1=2.2L\\T_1=30^oC=(30+273)K=303K\\V_2=?\\T_2=0^0C=(0+273)K=273K[/tex]

Putting values in above equation, we get:

[tex]\frac{2.2}{303}=\frac{V_2}{273}\\\\V_2=1.98L[/tex]

Thus the volume of the gas is 1.98 L
