2024年6月3日 · Ca(NO3)2 is the chemical formula of calcium nitrate. Wiki User. ∙ 8y ago. This answer is:

Try 2 HNO3, which gives 6 O atoms, and I had 2 from the Ca(OH)2 already, so I have a total of 8 O atoms now. Right side, you need 8 total, but only have 7. Since H20 has only one O atom, if you place a 2 in front of the H20, you have 2 O atoms now.

2024年6月4日 · For Ca(NO3)2, you would add the Atomic Mass of calcium (Ca), two nitrogen atoms (N), and six oxygen atoms (O) found in two nitrate (NO3) ions. The formula mass would be 164.09 g/mol. The formula ...

2024年6月12日 · Calcium nitrate formula is Ca(NO3)2, which contains one calcium atom (Ca), two nitrogen atoms (N), and six oxygen atoms (O). So, the total number of atoms in calcium nitrate is 1 + 2 + 6 = 9 atoms.

2020年5月5日 · Ca(NO 3) 2 (aq) + 2HCl(aq) ==> CaCl 2 (aq) + 2HNO 3 (aq) This reaction DOES NOT OCCUR because no precipitate, gas or liquid is formed as a product. All species are fully dissociated and soluble so there is no reaction. However, if you want to solve the problem as an "exercise" then here goes: Ca(NO 3) 2 + 2HCl ==> CaCl 2 + 2HNO 3

2025年1月28日 · The balanced equation for Ca + Mg(NO3)2 would be Ca + Mg(NO3)2 -> Ca(NO3)2 + Mg. This is a double displacement reaction, where the calcium (Ca) and magnesium (Mg) ions switch places with the ...

2024年6月4日 · There are a total of 11 atoms in Ca(NO3)2: 1 calcium atom (Ca), 2 nitrogen atoms (N), and 6 oxygen atoms (O) from the nitrate (NO3) groups. AnswerBot ∙ 10 mo ago

2024年6月7日 · The oxidation number of Ca in Ca(NO3)2 is +2, which is a common oxidation state for calcium in compounds. The oxidation number of each oxygen in the nitrate ion (NO3-) is -2, making the overall ...

2021年5月30日 · b. is the correct answer. The balanced equation shows that 2 moles of Cu(NO 3) 2 are required for each mole of Ca used. As 1.5 moles of Ca is used, there would have to be 3.0 moles of Cu, but there are only 2 moles of Cu(NO 3) 2.

2016年2月11日 · By the method of half-equations: calcium metal is oxidized, and nitrogen is reduced. Oxidation: Ca(s) rarr Ca^(2+) + 2e^- (i) Reduction: 2HNO_3(aq) +4e^(-) +4H^(+) rarr N_2O_3 +3H_2O (ii) Note that dinitrogen trioxide is a metastable species, and is a mixed valence oxide of N(II+) and N(IV+), hence an average oxidation state of III+. Both (i) and (ii) are …
