Answer:
Carbon monoxide + hydrogen ------> methanol
Explanation:
In writing a chemical equation, the substances which react together to form other substances are known as products and are usually placed on the left side of a the equation, whereas the substances that are formed by the reactants are known as products and are usually written on the right side of the equation. A forward pointing arrow is usually placed between the reactants and and products to show how the reaction proceeds from reactants to formation of products.
From the given equation, methanol is the product formed from the reactants carbon monoxide and hydrogen. Therefore, the equation will be:
carbon monoxide + hydrogen -----> methanol
Quartz<span> is the second most abundant </span>mineral<span> on </span>Earth<span>'s </span>continental crust, it can be colourless to black and has the lowest weathering potential in the Goldich dissolution series and therefore it is commonly found as a residual mineral in river sediments and residual soil.
Answer:
Elemental S reacts with O2 to form SO3 according to the reaction 2S+3O2→2SO3 Part B: What is the theoretical yield of SO3 produced by the quantities described in Part A? Express your answer numerically in grams.
Part A: 1.88x10^23 O2 molecules are needed to react with 6.67 g of S.
