How many aluminum atoms are there in a 15.1 gram soda can?

Biology
1 answer:
MariettaO [177]2 years ago
6 0
A soda can is made from aluminum metal. To determine how many atoms of this element is present in a certain mass of the can, we need to convert the mass into units of moles by using the atomic mass of aluminum which is 26.98 g per mol. Then, we use the Avogadro's number. It represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles or vice versa.

moles Al = 15.1 g Al ( 1 mol / 26.98 g ) = 0.56 mol Al
atoms Al = 0.56 mol Al ( 6.022x10^23 atoms / 1 mol ) = 3.32x10^23 atoms

OPTION A would be the closest.

A fossil mold that reflects the shape and surface markings of an organism is created when _____.
Lady bird [3.3K]

Correct answer: D). The organism is buried in sediment and then dissolved by underground water

Mold is a copy of an organism, it is formed like the first layer of sediments harden and forms a mold. Then after that new layer of sediment fills and become hardens.

The fossil is left behind in sediment, which removes the remains of an organism from its surrounding material. The groundwater along with its mineral content dissolves the organic matter to form the fossil.

Which statement about DNA replication is FALSE?
Alexandra [31]

Answer:

C. DNA ligase adds nucleotides to the lagging strand

Explanation:

DNA replication is the process during cell division in which DNA copies itself. DNA strands unwind with the help of helicase to initiate the process. DNA Polymerase III is responsible for prokaryotic replication and adds nucleotides in 5' to 3' direction. Since both the strands of DNA run in opposite direction their replication is slightly different. The lagging strand is also formed by DNA Polymerase III in discontinuous manner leading to formation of Okazaki fragments. DNA ligase joins these fragments once the replication process is completed.

Rudiy27

All of these components are reservoirs of carbon. The cycle is usually discussed as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels).
