Classify each of the following chemical reactions. Synthesis 2. The answer will appear below, Always use the upper case for the first character in the element name and the lower case for the second character. For ionic compounds, the positive ion in the first compound combines with the negative ion in the second compound, and the positive ion in the second compound combines with the negative ion in the first compound. The reaction; Na2CO3 + 2HCl → 2NaCl + H2O + CO2. Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide; To enter an electron into a chemical equation use {-} or e Enter an equation of a chemical reaction and click 'Balance'. Chemical reaction - Chemical reaction - Energy considerations: Energy plays a key role in chemical processes. While the Sodium ion on the hydroxide has been replaced by the Hydrogen ion. Types of Reactions: Synthesis (Combination), Decomposition and Combustion Synthesis (Combination) – A + B AB (1 product only) Decomposition – AB A + B (1 reactant only) Combustion of a hydrocarbon – C x H y + O 2 CO 2 + H 2 O Practice: Balance each reaction … Balancing Strategies: This is a neutralization reaction, and can also called a double displacement reaction. ÿT”TÅKC%¹z ¢÷—†Ü­z”Üá×û£Þ—>+~'W¿õÆ %íØÝû—>ÉÑj"léZéÈøӈãsTéÓèÃ[BkÛæ„ÉokâŒåVܨýŸOáë>Wã‹Bõ cÅ@e7ĸ*•¬KùÌgW…ë/$dx±ãOðý¡?ÄE>’‹ÂôÇøˆSWþår_fõW¢”¦¾ÜAX‚Aª5×¥Ó]ð}yAÆK[‰úÏÙÕÞÿ÷ÇӋBôË"ÇJ'kÜ?fIuIyôàžÅþª‰v®ä¼‹,Ù ¶ªÿ9Úmµ¼yºsnÖ9ÛYJȄ3¼XÝŧ&Ï÷“B÷7d†R³Â³¥µmÜ.WÀø q\L¶ r ÷S0ȃ—v OøÌɪØþÔÁ¹q~ã)–‹Ÿr+rmKÊj+®fwcýû Yސ$û+ÜÂò9ç½B–Z$"ÒôpÐ Ca (OH) 2 + 2HCl → CaCl ... 2 + 2HCl → CaCl 2 + 2H 2 O [ Check the balance ] Calcium hydroxide react with hydrogen chloride to produce calcium chloride and water.
