- Give the formula for the acidic oxide of (a) HNO3 (b) HNO2 (c) H2SO4arrow_forward4.48 Elemental phosphorous is used in the semiconductor industry. It can be obtained from an ore called fluoroapatite via reaction with SiO2 and C: 4Ca5( PO4)3F+18SiO2+30C3P4+30CO+18CaSiO3+2CaF2 Suppose a particular semiconductor production plant requires 1500 kg of P4. If the recovery of P4 from this reaction is 73% efficient, what mass of fluoroapatite is needed?arrow_forwardMg(OH)2(s)+2HNO3(aq)→ the balanced chemical formula?arrow_forward
- Consider the reaction: Ba(NO 3) 2( aq) + Na 2SO 4( aq) → BaSO 4( s) + 2NaNO 3( aq) Which of the following statements is correct? Barium is oxidized. This reaction is not an oxidation-reduction reaction. Nitrate ion is the reducing agent. Sulfate ion is the oxidizing agent. Sodium is reduced.arrow_forwardPredict the products of the following reaction. If no reaction will occur, use the NO REACTION butto Be sure your chemical equation is balanced! Sr(s) + H₂O(1) → [] · X NO REACTION Śarrow_forwardComplete, formulate, and balance the following equations: Calcium chloride + lead(II) nitrate Sodium sulfide + zinc chloride Barium hydroxide + Phosphoric acidarrow_forward
- How many moles of sodium will react with water to produce 4.5 moles of hydrogen in the following reaction? 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)arrow_forwardPredict the product(s) and write a balanced equation for each of the following redox reactions:(a) N2(g) + H2(g) →(b) NaClO3(s) →Δ(c) Ba(s) + H2O(l) →arrow_forward2 Al (s) + 3 Pb2+ (aq) → 3 Pb (s) + 2 Al3+(aq) which species acts as the oxidizing agent? Explain.arrow_forward
- Write the complete balanced chemical equation for the decomposition of solid sodium bicarbonate when heated. Balance and translate the given chemical equation to a word equation. Ca(OH)2(aq) + H3PO4(aq) -> Ca3(PO4)2(s) + H2O(l) 3. Write the balanced chemical equation corresponding to the following chemical reaction: Three moles of sodium bicarbonatereact with one mole of hydrogen phosphate to give one mole of sodium phosphate, three moles carbon dioxide and three moles water.arrow_forwardThere are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. In the first step, calcium carbide and water react to form acetylene and calcium hydroxide: CaC,(s)+2H,O(9)→C,H,(9)+Ca(OH);(s) In the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6C,H,(9)+3 CO,(9)+4H;O(9)→5CH,CHCO,H(9) Write the net chemical equation for the production of acrylic acid from calcium carbide, water and carbon dioxide. Be sure your equation is balanced.
