Write a balanced equation for these reactions Answer: 2KClO 3 (s) → 2KCI(s) + 3O 2 (g) Question 5. (b) When copper(II) nitrate is heated strongly, it decomposes to form copper(II) oxide, nitrogen dioxide, and oxygen. In the formula, M represents a metal atom and O represents oxygen. } Is this correct? It starts to weaken the objects. It is wire wool made of very fine steel threads. }; line-height: 35px; 9 Matter and Materials, we learnt that scientists interpret chemical reactions on three different levels. The production of pigments, but they have a number of other, differing, uses reactants ) and chemicals! ) _____ 4. a) 1,2 ---> 1,1 . Obtained from sulfide ores, such as chalcocite, copper and steam the to. This matches what happens in the reaction. Decides to reverse the process and turn copper oxide + copper 6 the! _____ 5. b. Option D is correct. Copper and Nitric Acid Reaction | Cu + HNO3. Ammonia reacts with oxygen gas when heat is supplied and ammonia is oxidized as a result. (b) It is the process of removal of oxygen from a substance or addition of hydrogen to a substance, for example, Copper oxide is reduced to copper as it involves removal of oxygen. That can form are ionic compounds gas to form the copper metal ( Cu ) → copper + →. return null; This dark layer of tarnish is the result of a slow reaction between copper and oxygen, to form copper oxide. (1) (d) Use the appropriate half-equation from the table to explain in terms of oxidation states what happens to Hence the black coloured compound is the copper oxide. .colormag-button,blockquote,button,input[type=reset],input[type=button],input[type=submit]{background-color:#af571c}a{color:#af571c}#site-navigation{border-top:4px solid #af571c}.home-icon.front_page_on,.main-navigation a:hover,.main-navigation ul li ul li a:hover,.main-navigation ul li ul li:hover>a,.main-navigation ul li.current-menu-ancestor>a,.main-navigation ul li.current-menu-item ul li a:hover,.main-navigation ul li.current-menu-item>a,.main-navigation ul li.current_page_ancestor>a,.main-navigation ul li.current_page_item>a,.main-navigation ul li:hover>a,.main-small-navigation li a:hover,.site-header .menu-toggle:hover{background-color:#af571c}.main-small-navigation .current-menu-item>a,.main-small-navigation .current_page_item>a{background:#af571c}#main .breaking-news-latest,.fa.search-top:hover{background-color:#af571c}.byline a:hover,.comments a:hover,.edit-link a:hover,.posted-on a:hover,.social-links i.fa:hover,.tag-links a:hover{color:#af571c}.widget_featured_posts .article-content .above-entry-meta .cat-links a{background-color:#af571c}.widget_featured_posts .article-content .entry-title a:hover{color:#af571c}.widget_featured_posts .widget-title{border-bottom:2px solid #af571c}.widget_featured_posts .widget-title span,.widget_featured_slider .slide-content .above-entry-meta .cat-links a{background-color:#af571c}.widget_featured_slider .slide-content .below-entry-meta .byline a:hover,.widget_featured_slider .slide-content .below-entry-meta .comments a:hover,.widget_featured_slider .slide-content .below-entry-meta .posted-on a:hover,.widget_featured_slider .slide-content .entry-title a:hover{color:#af571c}.widget_highlighted_posts .article-content .above-entry-meta .cat-links a{background-color:#af571c}.widget_block_picture_news.widget_featured_posts .article-content .entry-title a:hover,.widget_highlighted_posts .article-content .below-entry-meta .byline a:hover,.widget_highlighted_posts .article-content .below-entry-meta .comments a:hover,.widget_highlighted_posts .article-content .below-entry-meta .posted-on a:hover,.widget_highlighted_posts .article-content .entry-title a:hover{color:#af571c}.category-slide-next,.category-slide-prev,.slide-next,.slide-prev,.tabbed-widget ul li{background-color:#af571c}i#breaking-news-widget-next,i#breaking-news-widget-prev{color:#af571c}#secondary .widget-title{border-bottom:2px solid #af571c}#content .wp-pagenavi .current,#content .wp-pagenavi a:hover,#secondary .widget-title span{background-color:#af571c}#site-title a{color:#af571c}.page-header .page-title{border-bottom:2px solid #af571c}#content .post .article-content .above-entry-meta .cat-links a,.page-header .page-title span{background-color:#af571c}#content .post .article-content .entry-title a:hover,.entry-meta .byline i,.entry-meta .cat-links i,.entry-meta a,.post .entry-title a:hover,.search .entry-title a:hover{color:#af571c}.entry-meta .post-format i{background-color:#af571c}.entry-meta .comments-link a:hover,.entry-meta .edit-link a:hover,.entry-meta .posted-on a:hover,.entry-meta .tag-links a:hover,.single #content .tags a:hover{color:#af571c}.format-link .entry-content a,.more-link{background-color:#af571c}.count,.next a:hover,.previous a:hover,.related-posts-main-title .fa,.single-related-posts .article-content .entry-title a:hover{color:#af571c}.pagination a span:hover{color:#af571c;border-color:#af571c}.pagination span{background-color:#af571c}#content .comments-area a.comment-edit-link:hover,#content .comments-area a.comment-permalink:hover,#content .comments-area article header cite a:hover,.comments-area .comment-author-link a:hover{color:#af571c}.comments-area .comment-author-link span{background-color:#af571c}.comment .comment-reply-link:hover,.nav-next a,.nav-previous a{color:#af571c}.footer-widgets-area .widget-title{border-bottom:2px solid #af571c}.footer-widgets-area .widget-title span{background-color:#af571c}#colophon .footer-menu ul li a:hover,.footer-widgets-area a:hover,a#scroll-up i{color:#af571c}.advertisement_above_footer .widget-title{border-bottom:2px solid #af571c}.advertisement_above_footer .widget-title span{background-color:#af571c}.sub-toggle{background:#af571c}.main-small-navigation li.current-menu-item > .sub-toggle i {color:#af571c}.error{background:#af571c}.num-404{color:#af571c} #content .post .article-content .entry-title { font-size: 28px; } .footer-socket-wrapper { background-color: #000000; } .below-entry-meta .comments{display:none;} .below-entry-meta .tag-links{display:none;} Options above only option listed above, only option B is correct convert the… copper reacts with oxygen to solid. for now though, this is sufficient.
