Identify the phrases that generally apply to molecular compounds. A. Contains metals and nonmetals B. Are often fades or liquids C. Have low melting points D. Contain ionic bonds E. Use covalent bonding
Answer is option C) Have low melting points.
Explanation:
As is common knowledge, small molecules make up molecular compounds, and these small molecules are held together by an intermolecular force. The intermolecular tensions in this situation are incredibly weak and simple to overcome when breaking it. Therefore, molecular compounds have low melting and boiling points because of weak intermolecular interactions.
What are molecular compounds?Chemical substances known as molecular compounds assume the shape of distinct molecules. Examples include common substances like carbon dioxide and water. These substances differ significantly from ionic substances like sodium chloride. When metal atoms give up one or more of their electrons to nonmetal atoms, ionic compounds are created. The resultant cations and anions are drawn to one another electrostatically.

a student walks 40 meters east, 20 meters north, 60 meters west and 20 meters south. whats the displacment?
The Correct answer is 50 Meters,Displacement is defined to be the change in position of an object.
What is Displacement?Displacement is the term used to describe the shift in an object's location or the shortest path/length between two places. With such a magnitude and orientation, it is a vector quantity.
Whenever an item travels from location A to location B, its position changes.Displacement=Δx=x f −x 0
x f refers to the value of the final position.x_0x 0 refers to the value of the initial position.Δx is the symbol used to represent displacement.Displacement is a vector. This indicates that it has both a direction and a magnitude, and that it may be visualised as an arrow pointing from the starting location to the ending place.Calculate the Displacement of the ProblemThe student's path fortunately consisted of straight lines and right angles. Therefore we can use the pythagorean theorem to find the distance between where the student's path started and stopped.
A2+B2= C2.
We Give
meters east in for A, 40.
meters north for B 60 .
Distance =40+60+20=110m
Displacement OC= Root of (40 ²+30 ²)
= 50 m
That's the length of the distance between where the student started and where the student ended up.
A2 plus B2 equals C2. We plug 30. meters east in for A, and 40. meters north for B. 30. meters squared plus 40. meters squared equals 2500 meters2. Then we take the square root of that number and get 50. meters.

Scientists can identify a biome by defining the range of temperatures, the kind of soil, the amount of light, and the amount of water that are distinctive to that location. These factors create niches for particular species.A biome is a community made up of all the habitats in a given region and climate, whereas a habitat is the place where a group of one type of organism (a population) resides.

Por qué los alimentos se dañan con mayor facilidad a temperatura ambiente que cuando están en la nevera?
Answer:
Esto se debe a que la heladera tiene mucha menor temperatura que la temperatura ambiente.
Esta menor temperatura ayuda a luchar contra los microorganismos que están en los alimentos (bacterias, hongos, etc) pues detiene en gran medida su repreduccion, la cual se ve maximizada en los rangos entre 5°C y 60°C, tal que la temperatura ambiente suele estar en el rango donde los microorganismos prosperan y se reproducen, es por ello que los alimentos se conservan mucho mejor en ambientes fríos (como la nevera) que en temperatura ambiente.

Calculate the mass of water needed to prepare 45 g of salt solution if the salt content in the solution is 12%.
The mass of water needed to prepare 45 g of salt solution if the salt content in the solution is 12% is 330g.
The solute is the thing that needs to dissolve, and the solvent is the thing that needs to dissolve it. With a wide variety of solutes and solvents, solutions can be created. We are aware of a wide range of solutions.
Given,
Mass of the salt solution (Solute) = 45g
salt content in the solution = 12%
Let Mass of water = x
Total mass of solution = 45 + x
Concentration of solution = Mass of solute / Mass of Solution × 100
⇒ 12 = 45 / 45 + x × 100
⇒ 12/100 = 45 / 45 + x
⇒ 0.12 = 45 / 45 + x
⇒ 0.12 (45 + x) = 45
⇒ 5.4 + 0.12x = 45
⇒ 0.12x = 45 - 5.4

Explanation:
How many times more acidic is a solution with a pH of 2 compared with one with a pH of 5 Explain.
pH is a logarithmic scale.This implies that the acidity (H + concentration) changes by 10 times for each pH variation of one digit. For instance, a pH 4 solution contains 10 times more H + than a pH 5 solution. Since a pH 3 solution is 100 times more acidic than a pH 5 solution, it will contain 100 times more hydrogen ions (H +).
What is the pH scale?A water-based solution is described by its pH value. In general, an acidic solution is one with a small pH value, and an alkaline solution is one with a larger pH value (more basic). Since the pH scale is symmetrical around 7, a solution with a pH of 7 is completely neutral (neither acidic nor basic). Figure 1 displays a few instances of typical compounds and where they fall on the pH scale.
The concentration of hydrogen ions (H+) in a solution is directly measured by the pH value of the solution. Acids have high H+ concentrations, which results in low pH levels. There is hardly any H+ in bases. Large pH values, greater than pH 7, are present in basic liquids.

The final molarity of bromide anion in the solution when of sodium bromide is dissolved in of a aqueous solution of silver nitrate is 0.59M
Given the mass of sodium bromide (m) = 15.3g
Volume of aqueous solution of silver nitrate (V) = 250ml = 0.25L
Concentration of solution of silver nitrate (M1) = 0.40M
Let the final molarity of sodium bromide = M2
The volume of solution does not change when when sodium bromide is dissolved in it.
The aqueous solution of silver nitrate contains AgNO₃ ⇆ Ag⁺ +NO₃
Sodium bromide is dissociated as: NaBr ⇄ Na⁺ + Br ⁻
If we know the molecular weight of NaBr, we can directly calculate the ultimate molarity of the bromide ion (Br) from the molarity of NaBr by using the formula:
NaBr has a molecular weight of 102.89 g/mol.
So, M2 = (m/V) x 1mol of NaBr/Molec weight
= (15.3/0.25 )x 1 mol of NaBr/102.89 = 0.59mol/L = 0.59M

Baed on the preure information in the data table, how are the preure of light and heavy particle related to the preure of the mixed particle?
Based on the pressure information in the data table, the pressure of light and heavy particle related to the pressure of the mixed particle having same pressure and same volume.
Why do heavy and light particles experience the same pressure?The lighter H₂ molecules will hit the walls more frequently and with less force because they move faster and collide with them more frequently. Because both light and heavy molecules hit the walls with roughly the same average kinetic energy at the same T, their pressure and consequent volume will be equal.
As the temperature increases, the particles gain energy and accelerate their motion. The movement of heavier particles is slower than that of lighter ones at the same temperature. Both the environment and the particles' mass affect their actual average speed.
