Which of these is an ion with a plus 2 plus charge O Al Na Ca?
the atomic no of calcium is 20 so to reach the nearest noble gas electronic configuration it loses 2 electrons and forms + 2 ion.
Calculate the formula mass of the compound calcium hydroxide ca oh 2?
The formula mass of calcium hydroxide (Ca(OH)2) can be calculated by adding the atomic masses of each element in the compound. The atomic mass of calcium (Ca) is 40.08 g/mol, the atomic mass of oxygen (O) is 16.00 g/mol, and the atomic mass of hydrogen (H) is 1.01 g/mol. Ca: 40.08 g/mol O: 16.00 g/mol * 2 = 32.00 g/mol H: 1.01 g/mol * 2 = 2.02 g/mol Adding these together gives a formula mass of 74.1 g/mol for calcium hydroxide (Ca(OH)2).
Balance this equation CaOh plus H2So4 equals CaSo4 plus H2O?
The balanced equation is Ca(OH)2 + H2SO4 → CaSO4 + 2H2O.
What is revealed in the reaction Ca(OH)2(s) Ca2 plus (aq) plus 2OH-(aq)?
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
What is the electronic structure of beryllium?
Beryllium has an atomic number of 4, so its electronic structure is 2-2, meaning it has 2 electrons in its inner shell and 2 electrons in its outer shell. Its electron configuration is 1s^2 2s^2.
How many electrons does Ca plus 2 have?
Ca is Calcium It's Atomic Number is 20. So it has 20electrons. so 20+2=22 wala
Which of these is an ion with a plus 2 plus charge O Al Na Ca?
the atomic no of calcium is 20 so to reach the nearest noble gas electronic configuration it loses 2 electrons and forms + 2 ion.
Ca oh 2 plus h2so4?
Ca(OH )2 plus sulfuric acid yields water and CaSO4.
What is the atomic number of He plus?
The atomic number of helium (He) is 2. When He gains one electron to become He plus, it becomes an ion with a net charge of +1, but the atomic number remains the same as 2.
If 2 plus 2 equals 4 then what is an aba-ca-by eats a grabagobble?
The aba-ca-by =2
Is The Ca plus 2 ion larger than the Ca atom?
Mg2+ is larger Now, as for the logic behind this problem...The first thing to do is recognize that Ca2+ (Calcium) has lost 2 of its electrons, therefore its valence electron structure is the same as Ar's (Argon). Ar is in the same row as Mg. The trend for atomic radii is increasing to the left and down. Atomic radius increases to the left because the atoms to the right have more particles in the nucleus than their counterparts to the left; thus, the electrons are drawn closer to the nucleus, and the atomic radius is diminished.
Is Ca plus 2 an ion?
No, "Ca plus 2" is not correct notation for an ion. The correct notation would be Ca^2+, which represents a calcium ion with a 2+ charge due to the loss of two electrons.
How is a calcium ionca plus 2 former from calcium atom?
The calcium ion Ca^2+ is derived from the calcium atom Ca when the Ca loses 2 electrons. Thus,Ca ===> Ca^2+ + 2e-
What do you get when you mix Ca plus 2 and NO3 -1?
You will make Calcium Dinitrate or Ca(NO3)2
What is the chemical equation for nitric acid plus calcium hydroxide plus calcium nitrate plus water?
Word equation: Sodium Hydroxide + Calcium Nitrate --> Calcium Hydroxide + Sodium Nitrate Chemical equation: Ca(NO3)2 + 2NaOH --> Ca(OH)2 + 2NaNo3
What is the symbol for Calcium in the Periodic Table?
The atomic symbol for an isotope of calcium will be the regular symbol for calcium, Ca. The number of protons will differ from standard calcium. This is written below the mass number Ca.
How do you balance this equation caoh2 plus na2co3 plus hno3?
The balanced chemical equation is Ca(OH)2 + Na2CO3 + 2HNO3 → Ca(NO3)2 + 2NaOH + CO2 + H2O
