What element is H12?
The element is Hydrogen. Given that H stands for Hydrogen.
Which gas is given out when sodium hydroxide reacts with a metal?
Hydrogen gas is given off when sodium hydroxide reacts with a metal. This is due to the displacement reaction that occurs where the more reactive metal displaces hydrogen from water molecules in the sodium hydroxide solution.
Does hydrogen diffuse faster than methane?
Yes, hydrogen diffuses faster than methane. The hydrogen molecule, H2, is the smallest of all molecules and it is considerably smaller than the methane molecule, CH4. Smaller molecules move faster, and therefore diffuse faster, at any given temperature, than larger molecules.
What gas diffuses ammonia gas or hydrogen chloride gas?
Ammonia gas diffuses faster than hydrogen chloride gas due to its lower molar mass and higher diffusion coefficient. The lighter ammonia molecules move quicker and spread out faster than the heavier hydrogen chloride molecules in a given amount of time.
How many moles of hydrogen gas contained in 9.03x1023?
Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2
When water boils does it turn into hydrogen molecules and oxygen molecules?
When water boils it is converted into steam. When water is in liquid state the molecule are close together. When in a gaseous state they are separated So, your answer is no they aren't turned into different molecules they are the same H2O, just farther apart.
What name is given to bonding between water molecules?
Bonding between water molecules is referred to as hydrogen bonds.
What name is given to the bond between water molecules?
The bond between water molecules is called the hydrogen bond.
What is the name given to the water molecule?
The bond between water molecules is called the hydrogen bond.
What element is H12?
The element is Hydrogen. Given that H stands for Hydrogen.
How many hydrogen atoms does 2nh3 make?
2NH3 molecules contain a total of 6 hydrogen atoms. This is because each NH3 molecule has 3 hydrogen atoms, and there are 2 NH3 molecules in the given compound.
The gas given off by a battery being charged is what?
Hydrogen
When a gas is given off as a liquid boils it is an example of a?
When a gas is given off as a liquid boils, it is an example of a phase change. As the liquid temperature increases, the kinetic energy of the molecules rises until they break free from the intermolecular forces holding them in the liquid state, thus transitioning into the gas phase.
By heating a liquid and measuring the temperature at which it boils what is being measured?
It is the boiling point of that liquid under the given conditions of pressure.
Which gas is given out when sodium hydroxide reacts with a metal?
Hydrogen gas is given off when sodium hydroxide reacts with a metal. This is due to the displacement reaction that occurs where the more reactive metal displaces hydrogen from water molecules in the sodium hydroxide solution.
When mg reacts with hydrogen acid what gas is given off?
I assume you mean this reaction. Mg + 2HCl -> MgCl2 + H2 That is hydrogen gas being given off. ( H2 )
Can penicillin be uses on boils?
Yes, penicillin can cure boils. The penicillin usually given for boils is Flucloxacillin. If a person is allergic to penicillin, they will be given a different antibiotic.
