An element is determined by what?
By the number of protons in the nucleus. So the atomic number decides the element. If it is 1, then that is Hydrogen element. 2 is for Helium, 3-Lithium, 4-Berilium, 5-Boron and so on. Gold element has 79 protons in its nucleus. Mercury has 80. So with a high sophisticated technology if we take only one proton from each mercury atom, then we can produce gold. So mercury has been changed into gold. So transition of element is only by physical means not by chemical means.
What happens when a atom loses an electron?
When an atom loses an electron, it becomes positively charged and is called a cation. This loss of an electron reduces the number of negatively charged electrons compared to the number of positively charged protons in the nucleus. The atom becomes more reactive as it seeks to gain electrons to achieve a stable electron configuration.
At what temperature C will xenon atoms have the same average speed that Cl2 molecules have at C?
At any given temperature, the average speed of a gas can be determined using the root-mean-square speed formula: Urms = sqrt[(3RT)/M]. For xenon atoms to have the same average speed as Cl2 molecules at a specific temperature, the root-mean-square speed of both gases should be equal. By setting up and solving the equations, you can determine the temperature at which this equality occurs.
What temperature will xenon atoms have same average speed that Cl2 molecules have at 24 degrees C?
First you need to find the root mean square speed of Cl2 at 24 degrees C using the formula sqrt(3RT/Mm) where R is the gas constant, T is the temperature in K, and Mm is molar mass. Approximately 34.24 m/s. Now perform a simple algebra problem to solve for the temperature Xenon atoms will reach this speed.
What element is found in a diatomic molecule and has the same properties as a gas found in earth's atmosphere?
There a multiple elements that fit this description. Oxygen is a diatomic gas found in the earth's atmosphere. Nitrogen is also a diatomic gas found in the earths atmosphere. Thus, both of these elements fit the description.
Is Br2 plus NaCl equals NaBr plus Cl2 possible or not?
No, the reaction Br2 + NaCl → NaBr + Cl2 does not occur. The correct reaction between Br2 and NaCl is 2NaBr + Cl2.
What is the equation of reaction between chlorine and magnesium?
MgBr2 + Cl2 yields MgCl2 + Br2 is an example of an anionic single replacement chemical reaction.
Balance Cl2 plus KBr - Br2 plus KCl?
The balanced equation for Cl2 + 2KBr -> 2Br2 + 2KCl is balanced as it conserves the number of atoms on both sides of the reaction. Two moles of KBr reacts with one mole of Cl2 to produce two moles each of Br2 and KCl.
Write balanced equations for KCl and Br2?
KCl: 2K(s) + Cl2(g) -> 2KCl(s) Br2: Br2(l) -> 2Br(s)
What is the mole ratio of Cl2 to Br2 in the given reaction?
The mole ratio of Cl2 to Br2 in the given reaction is 1:1. This means that for every 1 mole of Cl2 that reacts, 1 mole of Br2 is also involved in the reaction.
What color are Cl2 Br2 F2 and I2?
I2 is deep purple color. Br2 is a reddish brown, Cl2 is a green. F2 is yellow.
Chlorine and bromine balanced equation?
The balanced chemical equation for the reaction between chlorine (Cl2) and bromine (Br2) is: Cl2 + Br2 -> 2ClBr
What is the balanced equation form of potassium bromide and chlorine to form potassium chloride and bromine?
2KBr + Cl2 ----> 2KCl + Br2
What is the balanced equation for magnesium bromide and chlorine?
Bromine is diatomic, so 2 atoms make up Bromine as a reactant. Mg + Br2 ----> MgBr2
What is the most correct product formed from the reation of LiBr plus Cl2?
The most correct product formed from the reaction of LiBr + Cl2 is LiCl + Br2. This is because lithium chloride (LiCl) and bromine (Br2) are the expected products when lithium bromide (LiBr) reacts with chlorine (Cl2) in a single displacement reaction.
What is the equation for the reaction between bromine and potassium chloride?
The equation for the reaction between bromine and potassium chloride is: 2KCl + Br2 -> 2KBr + Cl2
What is the balanced equation for Magnesium bromide plus chlorine yields magnesium chloride plus bromine?
The balanced equation is: 2MgBr2 + Cl2 → 2MgCl2 + Br2
