Answer:
Mg(OH)2 + 2HCI ⇒ MgCI2 + 2H2O
Explanation:
In order to balance a chemical equation you need to make sure both sides of the equations are equal.
Mg(OH)2 + 2HCI = MgCI2 + H2O
Mg = 1
Oh = 2
HCI = 2
Products:
Mg = 1
CI = 2
H = 2
O = 1
2H20 = 1 × 2 = 2
2 × 2 = 4
2HCI
1 × 2 = 2
Mg(OH)2 + 2HCI ⇒ MgCI2 + 2H2O
Hope this helps.

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.
What is glacial acetic acid? What function does it have?
Answer:
Acetic acid, systematically named ethanoic acid, is an acidic, colourless liquid and organic compound with the chemical formula CH₃COOH. Diluted, glacial acetic acid is used in preservation and canning of pickles and other vegetables. It is also used as a descaling agent for cleaning.
Explanation:
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 =.
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.)

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
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.

Suppose you wish to jump horizontally and in order for you to jump a distance of 4 feet horizontally, you must exert a force of 200 N. When you are standing on the ground, you have no trouble jumping 4 feet horizontally. If you are standing in a canoe, however, and you need to jump 4 feet to reach the pier, you will surely fall into the lake. Why is it that you cannot jump 4 feet out of a canoe when you can easily do this when on land?
