Chemistry
1 answer:
nata0808 [166]3 years ago
4 0

Answer: 4.35%

Explanation:

Scientists estimate that the current composition of gases in the Earth's atmosphere has been stable for the last 200 million years or so.

If the Earth was formed 4,600 million years ago then the percentage of her age that the atmosphere has been in its composition is:

= 200 / 4,600 * 100%

= 4.35%

What else is produced during the combustion of butane, C4H10?
denpristay [2]

Another product: CO₂

<h3>Further explanation</h3>

Given

Reaction

2C₄H₁₀ + 13O₂⇒ 8__+ 10H₂O

Required

product compound

Solution

In the combustion of hydrocarbons there can be 2 kinds of products

If there is excess Oxygen, you will get Carbon dioxide(CO₂) and water in the product

If Oxygen is low, you'll get Carbon monoxide(CO) and water

Or in other ways, we can use the principle of the law of conservation of mass which is also related to the number of atoms in the reactants and in the products

if we look at the reaction above, there are C atoms on the left (reactants), so that in the product there will also be C atoms with the same number of C atoms on the left

2C₄H₁₀ + 13O₂⇒ 8CO₂+ 10H₂O

The field lines around one end of a bar magnet are shown below.
Vladimir [108]

Answer:

<em>The correct option here would be the third one because it is true. </em>

Explanation:

The diagram shows a bar magnet that has lines that are parallel to each other and are pointing towards one side of the rectangle.

The side of rectangle is South Pole because the arrows that are shown in the diagram are nothing but field lines and these lines tend to start from North Pole and the arrow shows moving inside that point hence that point it would be South Pole showing field lines ending at it.
