Answer 1

$\huge\mathtt {\red{\underline{Summary:-}}}$

$\sf →\: A \: complete \: chemical \: equation \: \\ \sf \: \: \: \: represents, \: the \: reactants \: products \: and \: \\ \sf \: \: \: \: \: their \: physical \: states \:symbolically.$

$\sf→\:A \: chemical \: equation \: is \: balanced \: so \: that \: \\ \sf numbers \: of \: atoms \: of \: each \: type \: involved \\ \sf in \: a \: chemical \: reaction \: are \: the \: same \: on \\ \sf the \: reactant \: and \: product \: sides \: of \: the \\ \sf equation. \: equations \: must \: always \: be \\ \sf balanced.$

$\sf→\: In \: a \: combination \: ration \: two \: or \: more \\ \sf substances \: combine \: to \: form \: a \: new \\ \sf single \: substance.$

$\sf→\: Decomposition \: reactions \: are \: opposite \: to \\ \sf the \: combination \: reactions. \\ \sf In \: a \: decomposition \: reaction, \: a \: single \\ \sf substances \: decomposes \: to \: give \: two \: or \\ \sf more \: substances.$

$\sf→\: Reactions \: in \: which \: heat \: is \: given \: out \\ \sf along \: with \: the \: products \: are \: called \: \\ \bf \red{exothermic \: reactions.}$

$\sf→\: Reactions \: in \: which \: energy \: is \: absorbed \\ \sf \: are \: known \: as \: \bf \red{endothermic \: reactions.}$

$\sf→\: When \: an \: element \: displaces \: another \\ \sf element \: from \: its \: compound, \: a \: \\ \bf \red{displacment \: reaction} \sf \: occurs.$

$\sf→\: Two \: different \: atoms \: or \: groups \: of \: atoms \\ \sf (ions) \: are \: exchanged \: in \: \bf \red{double} \\ \bf \red{ displacement \: reactions.}$

$\sf→\: Precipitation \: reactions \: produce \: \\ \bf \red{insoluble \: salts.}$

$\sf→\: Reactions \: also \: involve \: the \: gain \: or \: loss \\ \sf of \: oxygen \: or \: hydrogen \: by \: substances. \\ \\→ \bf\red{Oxidation} \sf \: is \: the \: gain \: of \: oxygen \: or \: loss \\ \sf of \: hydrogen. \\ \\ → \bf\red{Reduction} \sf \: is \: the \: loss \: of \: oxygen \: or \: gain \\ \sf of \: hydrogen.$
