The answer is D. To put it simply, all atom wished to become stable. The only way for that is to obtain an octet structure where the outermost shell would have 8 electrons, thus being full.
Answer:
Temperature gradient = 30
90F - 60F = 30F
The temperature gradient is 30F.
If I am right, let me know.
Answer:
A. Whenever the population has increased, steel consumption has increased as well.
Explanation:
Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen on the graph is that whenever the population has increased, steel consumption has increased as well.
A critical look at the graph, you will discover that the population and the steel consumption are moving upwards (i.e they are increasing). It's seen that as the population increases, steel consumption increases. This is true because as the population increases, people are building houses, more transportation systems that require steel are being manufactured, more household utensils that are steel products are being fabricated etc; therefore the consumption of steel increases.
12/12= 1 mol
this is because: amount of moles=mass/relative formula mass and the relative formula mass of carbon is 12
<span>Permafrost soil (gelisol) is b. fragile. Permafrost soil is a region of the Earth's surface (ground or soil) that is at a temperature below freezing temperature. This makes it very brittle and sensitive to heat exposure, making it very fragile. This is often found in countries where the climate is very cold such as Canada etc.</span>
