larisa86 [58]3 years ago
5 0
At STP, 1 mol of gas occupies 22.4 L.
                                     mol O2 = 68.5 L * 1 mol/22.4 = 3.06 mol
The answer is that there are 3.06 mol of oxygen gas at STP.

Answer:

Balanced forces are equal in size and opposite in direction. When forces are balanced, there is no change in motion. In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force. You observed that the object did not move.

Explanation:

hope this helps if not im sorry

balance the reaction equation describing the biological formation of glucose (c6h12o6) with the lowest set of whole number coeff
Ivan

The given reaction equation for photosynthesis whereby, in the presence of light energy from the Sun and chlorophyll, plants synthesize glucose from carbon dioxide and water.  As water is present as a reactant, it doesn’t also appear on the ’products’ side of the equation. So:

Water + carbon dioxide > glucose + oxygen.

As glucose contains 6 carbon atoms, these must be obtained from 6 molecules of CO2. So, overall:

6CO2(g) + 6H2O(l) > C6H12O6(aq) + 6O2(g).

What is photosynthesis?

Photosynthesis is the process  plants and other organisms use to convert light energy into chemical energy, which is later released through cellular respiration to power the activity of the organism.

Therefore, This is the equation for photosynthesis whereby, in the presence of light energy from the Sun and chlorophyll, plants synthesize glucose from carbon dioxide and water.

How is stoichiometry used to calculate the amount of product from amount of reactant?
IceJOKER [234]
<span>Stoichiometry deals with the quantitative measurement of reactants and products in a chemical reaction. Let suppose you are given with following reaction;

                                            A  +  2 B   </span>→    3 C

According to this reaction 1 mole of A reacts with 2 moles of B to produce 3 moles of C. Now using the concept of mole one can easily measure the amount of reactants reacted and the amount of product formed, as...

                    1 Mole Exactly equals 6.022 × 10²³ particles

                    1 Mole of Gas (at STP) exactly occupies 22.4 L Volume

                    1 Mole of any compound exactly equals the molar mass in                                 grams

Therefore, <span>Stoichiometry is very helpful in quantitative analysis.</span>
