If a 1.00 kg sample of sand containing some gold … Which of the following are enforcement notices that may be sent when health and safety legislation is breached? Select two answers Improvement notice … 3 structural components of an amino acid that contribute to its pka value? A concentration cell is based on the aqueous reaction Cu2+(1.00 M) → Cu2+(0.0100 M). The cell consists of copper electrodes dipping into solutions of … WHAT MAKES CARBON ELEMENT SO SPECIAL A student attempted to find the mass of a warm beaker on a triple beam balance. What problems might the student encounter in trying to measure the mas … what is chemistry all about There will be no need for state symbols. First of all, to balance these equations, list the number of each atom, for both sides of the equation. In this example, it would be: Carbon: 3 Carbon: 1Hydrogen: 8 Hydrogen: 2Oxygen: 2 Oxygen: 3 The first step would be to balance out the carbons on the products side by multiplying CO2 by 3. The new equation will be: C3H8 + 02 ----> 3CO2 + H20 Now the carbons are balanced, we will look at the hydrogens. We can multiply the number of waters on the product side by 4, to make 4 H20 molecules. This gives both sides of the equation 8 hydrogens. Next, we can check our oxygens. There will be 10 oxygens on the products side and 2 on the reactants. So, to balance these out, we multiply the 02 on the reactants side by 5. The final equation will be: C3H8 + 502 ----> 3CO2 + 4H20 |
What is the correct coefficient for O2 when the following equation is correctly balanced C3H8 O2 CO2 H2O?
