Explosion : CAUSE AND EFFECT
"If you light a match in a room with hydrogen gas and oxygen gas, there will be an explosion and most of the hydrogen and oxygen will combine to create water molecules."
Demi : hello mely, are you okay today?
Melyca : yes, i am oke
Demi : Do you know the explosion that happened at the chemical plant yesterday?
Melica : yes, i know . why ?
Demi : What causes the explosion to occur?
Melica : because they light a match in a room with hydrogen gas and oxygen gas. So what do you think is the efect of that?
Demi : oh of course the explosion and than most of the hydrogen and oxygen will combine to create water molecules.
Melica : oke ,thanks demi.see you in class.bye ..
Demi : bye .

What are the uses of hydrogen in everyday life, explain and give an example!
BalasHapusThanks ,nadila 🙏
Hapushydrogen is used for a variety of purposes and within a variety of products for everything ranging from fuel to disinfecting to the creation of a variety of useful products found around the home.
Hidrogen use :
1.For inflating balloons
Due to its low weight, one of the key uses of hydrogen gas is in balloons.
2.In industries
There are a wide range of industrial uses of hydrogen in the chemical industry, food industry, paint industry, fertilizer industry, and so on. In the food industry, hydrogen is used to manufacture hydrogenated vegetable oils like butter, margarine, etc.

I can you understand, i you don't. Please ask to me 👍📚
What is the meaning of this sentence:If you light a match in a room with hydrogen gas and oxygen gas, there will be an explosion and most of the hydrogen and oxygen will combine to create water molecules.
BalasHapusAnd why did it happen? Please explain briefly ..
Hydrogen gas (dihydrogen or molecular hydrogen)[15] is highly flammable and will burn in air at a very wide range of concentrations between 4% and 75% by volume.[16] The enthalpy of combustion is −286 kJ/mol:[17]
Hapus2 H2(g) + O2(g) → 2 H2O(l) + 572 kJ (286 kJ/mol)[note 2]
Hydrogen gas forms explosive mixtures with air in concentrations from 4–74% and with chlorine at 5–95%. The explosive reactions may be triggered by spark, heat, or sunlight. The hydrogen autoignition temperature, the temperature of spontaneous ignition in air, is 500 °C (932 °F).
H2 reacts with every oxidizing element. Hydrogen can react spontaneously and violently at room temperature with chlorine and fluorine to form the corresponding hydrogen halides, hydrogen chloride and hydrogen fluoride, which are also potentially dangerous acids.
I hope you understand my sister😊
With any element, can hydrogen bind?
BalasHapus
HapusThe hydrogen atom is highly reactive and can react with metal oxides such as silver, copper, timbale, bismuth, and mercury to produce the free metal. In addition, hydrogen atoms can also react with organic compounds to form complexes such as with C2H4 forming C2H6 and C4H10.
why molecules can burn?
BalasHapusNot true Melica ,but this :
Hapus"Burning is a chemical process by which two atoms or molecules will combine with each other. In burning, the two atoms or molecules will combine and release energy. Usually one of the two molecules is oxygen or something else chemically like it called an oxidizer. When the molecules combine and release energy, it is released in the form of heat and often light."
