<h3><u>Answer;</u></h3>
Ethane (C2H6) is the excess reactant
<h3><u>Explanation;</u></h3>
From the equation;
2C2H6 + 7 O2 → 4CO2 + 6 H2O
2 moles of ethane requires 7 moles of oxygen to produce 4 moles of CO2 and 6 moles of water.
The mole ratio of ethane : oxygen is 2 : 7
10 g of C2H6 = 10/30 g/mol = 0.333 moles
12.5 g of Oxygen = 42.5/32 g/mol = 1.328 moles
Using C2H6 as limiting; 0.333 moles pf C2H6 requires 0.333× 7 =2.331 moles of oxygen
Using oxygen as limiting; 1.328 moles of oxygen requires, 1.328/7 = 0.1897 moles of ethane.
Therefore; Ethane is the excess reactant by 0.333 - 0.1897 = 0.1433 moles
Answer:
Unicellular organisms consist of only one cell and multicellular organisms consist of many cell.
Explanation:
Living things made up of a cell are called unicellular beings. They are very small and simple. In other words, unicellular organisms are those that are formed only by a single cell in which all the vital functions necessary for life are produced. For this reason, they are mostly microscopic organisms. Examples of unicellular organisms are viruses or bacteria.
Multicellular organisms are made up of a large number of cells. They present, therefore, a greater complexity than unicellular organisms in terms of the functions they develop. All current multicellular organisms come from a single cell, that is, they begin their life being unicellular. That is, they are formed from a zygote. Some examples of multicellular organisms are mammals, fungi, and mosses.
So, <u><em>unicellular organisms consist of only one cell and multicellular organisms consist of many cell.</em></u>
