The water in the puddle had vanished, leaving nothing behind. Water moves from the Earth's surface to the atmosphere via evaporation.
What is evaporation ?A liquid transforms into a gas during evaporation. It is simple to picture when puddles of rain "vanish" on a hot day or when wet clothing dries in the sun.
In these instances, the liquid water is evaporating into a gas known as water vapor rather than really dissipating. Global evaporation takes place.
Heat energy causes the bonds holding the water molecules together to fall apart, which causes evaporation. On the stove, adding heat to liquid water is what you do when you boil water.
Steam is created when water changes from a liquid form to a gaseous state (water vapor) due to the bonding being broken by the additional heat.
Thus, evaporation takes place in this process.

What is the molarity of 48.6 g of magnesium (Mg) ions in 4 L H2O? Show cancelation of units to get credit. PLEASE HELP!!!
Answer:
0.50M (1 sig. fig.)
Explanation:
The problem objective is 'Molarity (M)', so set up given data to reduce to moles per liter. That is ...
Molarity = moles Mg/Liters of solution = (48.6g/24.31g·mole⁻¹)/(4Liters) = 0.499794323M (calc. ans.) ≅ 0.5M (1 sig. fig.)
the chemical bond between elements of the two terminals of the periodic table is
Answer:
Covalent bonds are much more common in organic chemistry than ionic bonds. A covalent bond consists of the simultaneous attraction of two nuclei for one or more pairs of electrons. The electrons located between the two nuclei are bonding electrons.
...
The sample contains 1. 02 mol S. To calculate the mole ratios of the elements, you will divide each molar amount by 1. 02 mol. Calculate the mole ratios of the elements in the compound. Round each ratio to the nearest whole number. Mole ratio of H:S = mole ratio of S:S = mole ratio of O:S =.

when you take 10 grams of salt, and dissolve it in 25 grams of hot water what is the solubility
Answer:
When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. ... Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

calculate the moles and Molecules presents in ammonia present in 5.6dm3
of its volume STP?
Answer: 0.25 moles NH3
1.51x10^23 molecules NH3
Explanation:
5.6dm3 (cubic decimeters)
1 dm^3 = 1 liter
We have 5.6L of ammonia (NH3 gas) at STP. All gases at STP occupy 22.4 liters/mole. Use this information as a conversion factor:
(22.4 L NH3)/(mole NH3)
Therefore:
(5.6L NH3)/(22.4 L NH3)/(mole NH3) = 0.25 moles NH3
Use Avogadro's number to convert moles to particles/molecules
(0.25 moles NH3)*(6.02x10^23 molecules/mole) = 1.51x10^23 molecules NH3

What is the importance of water?
IMPORTANCE:
Water is very important. Whether it's from washing your dishes to hydrating, to simply just watering your flowers, water is important.
Washing Dishes
When you eat, after you eat, you wanna clean your dish. You're not gonna keep it dirty, you're going to have to wash it. Soap and water are often used when washing dishes. It's the best way to get it cleaned.
Hydration
Drinking water can have many benefits. It can make you more productive, you can even lose weight, no migraines, and it can boost your metabolism.
Watering Flowers
It's helpful to water plants because watering them on a basis/routine can help them gain nutrients. No watering the plant can result the plant drooping down and for it to become droopy and dry.
A sample of an unknown gas occupies 5.51 L at 1.31 atm. What pressure would thisgas exert in a 0.520 L container if the temperature is held constant?
Answer:
P₂ = 13.9 atm (3 sig. figs.)
Explanation:
The pressure (P), Volume (V) relationship with Temperature (T) & mass (n) held constant is an inverse proportionality. That is Boyles Law ...
P ∝ 1/V => P = k/V => k = P·V
For two pressure-volume conditions, the proportionality constant (k) remains constant where k₁ = k₂ and P₁·V₁ = P₂·V₂ => P₂ = P₁·V₁/V₂
Given:
P₁ = 1.31 atm.
V₁ = 5.51 L
P₂ = ?
V₂ = 0.520 L
V₂ = (1.31 atm)(5.51L)/(0.520L) = 13.88096154 atm (calc. ans.) = 13.9 atm (3 sig. figs.)
