The statement that describes a hydrogen bond is the bond between hydrogen in one water molecule and another hydrogen in a different water molecule. The correct option is b.

Hydrogen bonds are the bonds that are formed between water molecules and other molecules that join with hydrogen. These are weak bonds. This bond is formed between hydrogen atoms and other atoms.

One of the bonds that allow molecules to associate is the hydrogen bond. It happens when hydrogen forms a covalent bond with an element that is extremely electronegative, such as oxygen, nitrogen, or sulfur.

Thus, the correct option is b) the bond between hydrogen in one water molecule and another hydrogen in a different water molecule.

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:

We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol.

So 1 g water will contain 1/18 moles of H2O molecules.

Now 15 g of water will contain 15/18 moles of H2O.

So molecules of H2O = (15/18) x 6.022 x 10^23 = 5 x 10^23 molecules.

In this exercise we have to use the knowledge of lunar eclipse to identify the alternatives that correspond to this effect, as follows:

A lunar eclipse happens when the Earth is between the Moon and the Sun, at times when they are aligned. Depending on the position of the Moon, it is total, partial or penumbral. Different stages of a lunar eclipse on a full moon night.

Now,  use the knowledge of solar eclipse to identify the alternatives that correspond to this effect, as follows:

Solar eclipse is an astronomical phenomenon that occurs when the Moon is positioned between the Earth and the Sun, hiding the light emitted by the star towards the planet.

False. To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from 10.0 M stock solution, 4.0 mL of the stock solution and 16.0 mL of water would be needed.  

Recall the law of diffusion that:

C1V1 = C2V2, where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.

In this case, if C1 =10.0 M, V1 = ?, C2 = 2.00 M and V2 = 20.0 mL

V1 = 2 x 20/10

         = 4.0 mL

Hence, 4.0 mL of the stock solution would be taken. Since the final volume is 20.0 mL, only 16.0 mL of water would need to be added and not 20.0 mL.
