What weight of oxygen will react with 40 gram of ca?
For every 40 grams of calcium (Ca), 32 grams of oxygen (O) will be needed to react. This is based on the chemical formula for calcium oxide (CaO), where one calcium atom reacts with one oxygen atom to form one molecule of CaO.
Which was does not react with cold water Ca or Mg or Sr or Ba?
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
Which element or ion will spontaneously react with Ca?
Chlorine reacts readily with calcium. Calcium donates two electrons to this ionic bond and chlorine accepts one electron from calcium into its valance shell, so you need two chlorines to react with calcium. Ca(2+) and Cl- = CaCl2 Calcium chloride
When was Viaţa ca o pradă created?
Viaţa ca o pradă was created in 1977.
What is CA O?
Ca = calcium , O = oxygen and written together like CaO it stands for calcium oxide.
What is the total number of moles of Ca needed to react completely with 4.0 moles of water?
The balanced chemical equation for the reaction between calcium and water is Ca + 2H2O -> Ca(OH)2 + H2. This means that 1 mole of Ca reacts with 2 moles of water. Therefore, to react completely with 4.0 moles of water, you would need 2.0 moles of Ca.
What do HNO3 and CaOH23 make?
Nitric acid (HNO3) and calcium hydroxide (Ca[OH]2) react to form calcium nitrate (Ca[NO3]2) and water (H2O).
What is the ISBN of Viaţa ca o pradă?
The ISBN of Viaţa ca o pradă is 973-591-122-1.
What is Lewis structure of CaO?
The Lewis structure of CaO involves a calcium (Ca) atom with two valence electrons and an oxygen (O) atom with six valence electrons. The Ca atom donates its two valence electrons to the O atom, forming a bond. This results in a compound with a calcium cation (Ca^2+) and an oxide anion (O^2-).
Ca plus KOH equals?
They do not react, the Calcium cannot displace the Potassium as it is less reactive.
What is o in the phonetic alphabet?
O in the Phonetic Alphabet is Oscar (oss - ca )
What is Ca(OH)2 H3PO4 Ca3(PO4)2 H2O balanced?
To balance the equation involving calcium hydroxide (Ca(OH)₂), phosphoric acid (H₃PO₄), calcium phosphate (Ca₃(PO₄)₂), and water (H₂O), we need to ensure that the number of each type of atom is the same on both sides. The balanced equation is: 3 Ca(OH)₂ + 2 H₃PO₄ → Ca₃(PO₄)₂ + 6 H₂O. This indicates that three moles of calcium hydroxide react with two moles of phosphoric acid to produce one mole of calcium phosphate and six moles of water.
