The amount of oxygen in the reactants is 4 atoms. In the products, the oxygen is distributed to water (H2O) and O2 gas. Which co
Reil [10]

Answer:

2 in front of water and 1 in front of oxygen

Explanation:

This question is describing balancing a chemical reaction. A balanced chemical reaction has the same number of atoms of each elements on both the reactant and product side. According to the question, the reactants contains 4 atoms of oxygen. The reactants give rise to water (H20) and O2 in the products side.

This reaction is most likely the decomposition of hydrogen peroxide (H2O2) as follows:

H2O2 (l) ----> H2O (l) + O2(g)

Based on the description, H2O2 will be 2H2O2 as it is said to contain four atoms of oxygen. This means that, in order to have a balanced equation, we must place coefficient 2 in front of water and coefficient 1 in front of oxygen. That is;

2H2O2 (l) ----> 2H2O (l) + O2(g)

A pendulum takes 6.0 seconds to swing through 5 complete cycles. What is the period of the pendulum?
photoshop1234 [79]
When you look at this, you might not be sure which way to divide ...
Should you divide  6 by 5  or  5 by 6 ?

Here's a case where you can use your units to decide.

The question wants to know the 'period'.  That's a length of time,
so the answer needs to have units of time.

If you divide 'cycles' be 'time', you'll get  'cycles/second'.
That's Hz.  It's frequency, not time.

If you divide 'time' by 'cycles', you'll get 'seconds/cycle'.
That's time, and it's exactly the definition of 'period'.

            Period  =  (6 seconds) / (5 cycles)

                         =    (6 / 5)  seconds/cycle

                         =     1.2  seconds
