Calculate the total number of atoms in 15 g CaH2?
58,44 is the molecular weight of NaCl. So 15/58,44 = 0.257 moles would be contained in 15 g.
Calculate the number of oxygen atoms in 0.1 mole of calcium permanganate?
2.4 × 10^23 is the answer
What mineral is used to make fertilizer?
Fertilizer has three numbers for the ingredients. Nitrogen, phosphate and potash are the components. So when you buy fertilizer, the first number stands for the nitrogen, the second number for phosphate, and the third number is the potash. Calcium, sulfur, and magnesium are used as micronutrients.
How many protons neutrons and electrons are in an atom of calcium-42?
Calcium has atomic number 20, which means that all calcium atoms have 20 protons in their atomic nuclei. Neutral calcium atoms also have 20 electrons. Isotopes of calcium vary in the number of neutrons in their atomic nuclei, and are named for their mass number, which is the sum of the protons and neutrons in the nucleus. You can calculate the number of neutrons (N) in an isotope by subtracting the number of protons (atomic number) from the mass number. N = 42 - 20 = 22, therefore, a calcium-42 isotope has 20 protons, 20 electrons, and 22 neutrons.
What is the formula for germanium phosphate?
germanium has an oxidation number of +4, phosphate is PO4 has an oxidation number -3. Ge3(PO4)4
What is the valence number for calcium phosphate?
Calcium has valence of 2, forming the calcium ion Ca2+. The phosphate ion, PO43- contains five valent phosphorus and divalent oxygen along with three extra electrons. Compounds do not have a valence, atoms have a valence.
Calculate the total number of atoms in 15 g CaH2?
58,44 is the molecular weight of NaCl. So 15/58,44 = 0.257 moles would be contained in 15 g.
How many calcium ions in an 8.0 mole sample of calcium phosphate?
The formula unit for the most common form of calcium phosphate is Ca3(PO4)2. Therefore each formula unit, the ionically bonded counterpart of a mole for covalently bonded compounds, contains three calcium ions. The number of calcium ions in 8.0 "moles" of calcium phosphate is 3 [exact] X 8.0 X Avogadro's Number or 1.45 X 1025 atoms, where the depressed last digit of 1.45 indicates that this digit may not be significant. (The significant-digits-limiting datum is 8.0 moles.)

Is calcium carbonate milk?
Calcium Carbonate - CaCO3 This is found in rocks such as limestone and is the main component of seashells Calcium Chloride - CaCl2 This is a salt which is found naturally in very small quantities Calcium Hydroxide - Ca(OH)2 My understanding is that this does not occur naturally, it is very useful in many industries Calcium Oxide - CaO Created during the decomposition of limestone To name a few.
Calculate number of grams of sodium in 7.2 grams of sodium phosphate?
The gram atomic mass of sodium is 22.9898, the formula of the least hydrated form of sodium phosphate is Na3PO4.10 H2O, and the gram formula unit mass of this sodium phosphate is 344.09. Therefore, the mass fraction of sodium in this sodium phosphate is 3(22.9898)/344.09 or about 0.20044, and the grams of sodium in 7.2 grams of this sodium phosphate is 1.44 grams of sodium, to the justified number of significant digits.
How do you calculate the number of moles in 8.00 grams of calcium?
The molar mass of calcium is 40,078 g.40,078 g------------------------1 mol8 g---------------------------------xx = 8/40,078 = 0,2 moles
How do ADP and ATP differ in the number of phosphate molecules?
ADP have two phosphate molecules and ATP have three phosphate molecules in it.
What is atomic number for calcium?
The atomic number of calcium is 20.
What is the atomic number for calcium?
The most common calcium isotope, calcium-40, has 20 neutrons.
What is the formula for germanium phosphate?
germanium has an oxidation number of +4, phosphate is PO4 has an oxidation number -3. Ge3(PO4)4
