Answer: Natural gas has a faster rate because, being a carbon resource, it quickly replenishes as part of the carbon cycle.
Explanation:
Natural gas is a natural gas which consists of mixtures of hydrocarbons. It is primarily composed of methane, alkanes, small percentage of nitrogen, hydrogen sulfide, helium and carbon dioxide.
Being a carbon source it can be replenished easily due to decomposition of organic matter generated after the decomposition of dead animal and plant matter.
The geothermal energy can be define as the energy obtained from the hot springs it includes the water that includes the thermal energy generate through heat present in the geosphere.
Although the geothermal energy is the renewable source of energy but the time and period of it's generation remains unknown from the hot spring. Therefore, the rate of renewal of energy of natural gas is faster than the geothermal energy.
Answer:
Percentage error = 1.88 %
Solution:
Data Given:
Mass of Sample = 20.46 g
Volume of Sample = 43.0 mL - 40.0 mL = 3.0 mL
Formula Used:
Density = Mass / Volume
Putting values,
Density = 20.46 g / 3.0 mL
Density = 6.82 g.mL⁻¹
Percentage Error:
Experimental Value = 6.82 g.mL⁻¹
Accepted Value = 6.95 g.mL⁻¹
= 6.82 g.mL⁻¹ / 6.95 g.mL⁻¹ × 100 = 98.12 %
Percentage Error = 100 % - 98.12 %
Percentage error = 1.88 %
Answer:
B. C, A, B
Explanation:
We can measure the age of an artifact by comparison of the activities a living sample with that of the artifact. This is so because the activity of the living sample represents the original activity of the artifact.
So, the steps involved in determining the age of an artifact is to measure the ratio of the parent and daughter nuclei. Then we use the half life of carbon to find out how many half lives have passed. Using this number of half lives that has passed, we can compute the age of the object.
Answer:
As electrons are added to the valence shell, an extra proton (i.e fundamental, positively charged nuclear particle) is added to the element's nucleus. As electrons add and Z the atomic number increases 1 by 1, nuclear charge WINS, and electronic radii contract.
