<u>Answer:</u> The given quantity is a type of length and is measured i the units of meters.
<u>Explanation:</u>
For the given quantity which is 4.8 meters, the unit is meters ans it the unit used to measure the length of an object.
For example: The height of the building is 150 meters. This statement means that the length of the building from the ground is 150 and it is measured in the units of meters.
Hence, the given quantity is a type of length and is measured i the units of meters.
Answer:
The right answer to this is (b)
Using the ideal gas equation:
pV = nRT
n = pV / RT
1atm = 101325Pa, so p = 10132500Pa
1L = 0.001m^3, so V = 0.050m^3
R = 8.214 (ideal gas constant)
T = 273K
Hence moles of CO2 = (10132500 * 0.050) / (8.314 * 273) = 223.2101553
Reaction ratio between oxygen and CO2 is 1:2
Hence moles of O2 = 223... / 2 = 112 moles (3sf)
Answer:
1) Hydrogen Peroxide. Hydrogen Peroxide (H2O2) is a colourless liquid that resembles water in many respects. Its physical properties are very similar to those of water, except that it is 40% denser. ... The single bond between the two oxygen atoms is weak, so that H2O2 readily fragments into either H and HO2 or two OHs.
2) Is human activity warming the Earth or do recent signs of climate change signal natural variations? In this feature article, scientists discuss the vexing ambiguities of our planet's complex and unwieldy climate.
a) The Water Cycle. ... The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
b) Carbon is an essential element for life on Earth. Every living organism has carbon compounds inside each of its cells, such as fats and proteins. The carbon cycle shows how atoms of carbon can exist within different compounds at different times and be recycled between living organisms and the environment.
Explanation:
Answer:
EIt involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). ... Transcription is controlled separately for each gene in your genome.xplanation:
