Observation or inference<br> The container is filled to the 350 ml mark with water

Luba_88 [7]

Observation is acknowledging and noting some facts from the surroundings or the environment. Usually, observation is done using the five senses of human such as the sense of sight, sense of smell, sense of touch, sense of hearing and sense of tasting. It can also be qualitative and quantitative. Qualitative observations are those who use non-numeric forms in expressing the observation however quantitative uses numeric forms in presenting the observation. Inference on the other hand is the probable explanation or interpretation based on the observation given. Therefore, the statement "The container is filled to the 350 ml mark with water " is an observation.

In the three-dimensional structure of methane, ch4, the hydrogen atoms attached to a carbon atom are aligned ________. in the th

Nikitich [7]

Answer:
In the three-dimensional structure of methane, CH₄, the hydrogen atoms attached to a carbon atom are aligned <span><u>at the corners of a Tetrahedron</u>.

Explanation:
In Methane (CH</span>₄) the central atom (carbon) is bonded to four hydrogen atoms. So, the central atom is having four electron pairs and all pairs are bonding pairs and lacks any lone pair of electron. According to Valence Shell Electron Pair Repulsion (VSEPR) Theory the central atom with four bonding pair electrons and zero lone pair electrons will attain a tetrahedral geometry with bond angles of 109°. Hence, the shape of CH₄ is tetrahedral.

Which two factors must be considered when predicting whether two substances will dissolve in each other?

r-ruslan [8.4K]

The two factors must be considered when predicting whether two substances will dissolve in each other are type of bonds and size of the molecules are two factors.

<h3>What is solubility?</h3>

Solubility is the ability of solute particles to dissolve in any solvent, and solubility is directly proportional to the dissolving ability of the solute.

Solubility of any substance depends on the type of the bond present in the solute molecule i.e. polar or non polar. And it is also depends on the size of the solute as size defines the surface tenssion of the substance.

Number of bonds and shape of molecules are also define the solubility but not at that extent as their type and shape.

Hence type of bonds and size of the molecules are two factors.
