Answer:

To make a cloud, air needs only to be cooled to saturation and beyond. ... Usually the water vapor amounts in air are less that this amount. When this is the case, we describe the air as being unsaturated. If we add more vapor to such air, we could reach the maximum for the temperature

Explanation:

The atmospheric conditions required for the formation of clouds are , air needs only to be cooled to saturation and beyond formation of clouds and precipitation.

Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.

Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.f a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.

Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.

Answer:

Phosphate, any of numerous chemical compounds related to phosphoric acid (H3PO4).

An empty beaker weighs 34.49 g. when completely filled with water, the beaker and its contents have a total mass of 299.25 g. Volume does the beaker hold 264.76 mL.

mass of water = total mass - mass of beaker

mass of water = 299.25 g - 34.49 g

mass of water = 264.76 g

density of water = mass / volume

volume = mass / density

V = 264.76 g / 1.00g/mL

V = 264.76 mL

A physical body's overall composition is measured by its mass. This term also measures inertia, or the body's resistance to acceleration when a net force is applied. The strength of an object's gravitational pull to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit.

Answer:

Scandium(III) fluoride, ScF3, is an ionic compound. It is slightly soluble in water but dissolves in the presence of excess fluoride to form the ScF63− anion.

hope it will help you......

A high melting point is caused by a high fusion heat, a low fusion entropy, or a blend of the two. The crystal phase of highly symmetrical molecules is densely packed with many efficient intermolecular interactions, resulting in a higher enthalpy change on melting.

An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.

The intermolecular forces can be in order of strength, ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.

Because it is the power of attraction or repulsion between atoms or molecules rather than the ability to share or give/take electrons.

ScF3, or Scandium(III) fluoride, is an ionic compound. It is only slightly soluble in water, but in excess fluoride it dissolves to form the ScF63 anion.

Thus, due to the strong intermolecular forces, it have high melting point.

Answer:

WHY: You can abbreviate an element's electron configuration using the noble gas notation method because when you get down to the lower elements, specifically the d's and the f's, the electron configuration will be very long. The noble gas notation method is a faster answer while also being correct.

HOW: We can abbreviate an element's electron configuration by finding the last noble gas a specific element passed, for example calcium would have just passed Argon. Once you have the "address" of the previous noble gas, then you add on the difference between the element chosen and the noble gas, for example calcium would be [Ar] 4s^2.

Explanation:

The molarity of a solution that contains 20.0grams of sodium hydroxide in 200. ml of solution is 2.3 M.

Molarity is defined as the ratio of number of moles of solute to the volume of the solution.

Molarity = number of moles of solute/ Volume of solution

Given,

given mass of sodium hydroxide= 20 g

Volume of the solution = 200 mL.

Firstly, we will calculate the moles of sodium hydroxide.

Mole is defined as the ratio of given mass of substance to the molar mass of substance.

Mole = given mass/ molar mass

Molar mass of sodium hydroxide = 40 g

Mole = 20/40

= 0.5 mol

Molarity = (0.5/ 200) × 1000 = 2.5M

Thus, we calculated that the molarity of a solution that contains 20.0grams of sodium hydroxide in 200. ml of solution is 2.3 M.

Explanation:

this is a picture of a city that we have made worse everyday

Answer:

At higher altitudes, air pressure is lower. When atmospheric pressure is lower, such as at a higher altitude, it takes less energy to bring water to the boiling point. Less energy means less heat, which means water will boil at a lower temperature at a higher altitude.

In an ordinary container (exposed to atmospheric pressure). The freezing point will increase with altitude (and corresponding decrease in atmospheric pressure), but the difference is very slight.

Explanation:

When at a higher altitude , the atmospheric pressure is usually low and it

requires lesser amount of energy for the water to reach its boiling point. This

means that at higher altitudes , water boils at a lower temperature.

The freezing point of water increases with a higher altitude. This means that

water freezes at a higher temperature although the difference is very small.

The low pressure present in higher altitudes increases the melting point of

Volume of water = 10 mL

Volume of water + ring = 20 mL

Ring is made up of = ?

Solution:

Volume of ring = (Volume of water + ring) - Volume of water

Volume of ring = 20 mL - 10 mL

Volume of ring = 10 mL

Density:

Density = mass/volume     ( 1 mL = 1 cm³)

d = 89.2 g/  10cm³
