Answer:
Mass of carbon = 109.1 g
Explanation:
Given data:
Mass of carbondioxide = 400 g
Mass of carbon = ?
Solution:
Molar mass of carbon = 12 g/mol
Molar mass of CO₂ = 44 g/mol
Mass of carbon in 400g of CO₂:
Mass of carbon = 12 g/mol/44 g/mol × 400 g
Mass of carbon = 109.1 g
If I remember correctly, the answer is <span>Friction force.</span>
Answer:
Option (D)
Explanation:
Oil (crude and petroleum) is one of the major resources on earth in which the economy of a country is largely dependent on. These are non-renewable resources, which take thousands to million years of years in order to form.
It is highly essential. Every day, a large quantity of oil is being consumed. According to the researches done in the year 2015, it has been observed that the average global consumption of oil was 95 million barrels each day.
It has a high demand, and so it is being regularly used, and it has also been predicted that the present global oil reserves would be highly exhausted within the next 50 years.
Thus, the correct answer is option (D).
Answer is: <span>solid wood.
There are </span>five fundamental states of matter (gas, liquid, solid, plasma and Bose–Einstein condensate).
<span>In solid, molecules are closely packed, stiff and do not changes of shape or volume. S</span><span>olid object (in this example wood) does not take on the shape of its container.
</span>Liquids (in this example water) <span>have definite volume, but no fixed shape.
</span>Gases (in this example nitrogen and neeon) not have definite volume and fixed shape, it depends on its container.
V is more reactive, hope this helps!
