Answer:

a. Does not obey Conservation of Mass law

Explanation:

An example of an <em>unbalanced chemical equation</em> is:

  • H₂SO₄ + NaOH → Na₂SO₄ + H₂O

As you can see, there are two Na atoms on the right side of the equation, while only one on the left side, causing the masses on both sides of the equation to not be equal. In other words, <em>not fulfilling the Conservation of Mass law</em>.

<em>Compare with the correctly balanced equation</em>:

  • H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O

Now both sides of the equation possess the same number of atoms for each element.

Indicate the oxidation state for each of the following:
Nimfa-mama [501]
  • P2H2 Oxidation State - Diphosphene

       P2H2 has an oxidation number of +1. In P2H2, the oxidation    

        number of H is -1

  • H2C2O4 Oxidation State - Oxalic Acid

       C has an oxidation number of +3 in H2C2O4. O has an oxidation

        number of -2 in H2C2O4. H2C2O4 has an oxidation number of +1.

  • CrO2 Oxidation State - Chromium(IV) Oxide

         CrO2 has an oxidation number of +4.

<h3>Explain oxidation?</h3>

The oxidation state, also known as the oxidation number, is an atom's hypothetical charge if all of its bonds to other atoms were fully ionic.

The sum of the oxidation states of all the atoms in an ion equals the ion's charge.

A substance's more electronegative element is given a negative oxidation state. The one that is less electronegative is given a positive oxidation state.

In a car crash, large accelerations of the head can lead to severe injuries or even death. A driver can probably survive an acce
Alexxandr [17]

Answer:

Velocity, u = 14.7 m/s

Explanation:

It is given that, a driver can probably survive an acceleration of 50 g that lasts for less than 30 ms, but in a crash with a 50 g acceleration lasting longer than 30 ms, a driver is unlikely to survive.

Let v is the highest speed that the car could have had such that the driver survived. Using a = -50 g and t = 30 ms

Using first equation of kinematics as :

v=u+at

In case of crash the final speed of the driver is, v = 0

0=u+at

-u=at

-u=-50\times 9.8\times 30\times 10^{-3}

u = 14.7 m/s

So, the highest speed that the car could have had such that the driver survived is 14.7 m/s. Hence, this is the required solution.
