Yes; this process if called nuclear fusion, and an example of it is in the sun. Elements in the sun are combined to create heavier elements in order to provide fuel.

Answer:

I think it's quite simple.

Explanation:

An element is basically a group of similar atoms combined. For example, gold atoms combine to form a gold element (metal).
A compound is the product of the chemical combination of two or more atoms. For example, two Hydrogen atoms and an Oxygen atom combine to form water (a compound).
And a mixture is the product of the physical combination of two or more substances (not chemically combined). For example mixing water and milk powder. I hope it was helpful.

How many grams are in 3.14 x 1015 molecules of CO?
Vesnalui [34]

Answer:

Explanation:

Not Many

1 mol of CO has a mass of

C = 12

O = 16

1 mol = 28 grams.

1 mol of molecules = 6.02 * 10^23

x mol of molecules = 3.14 * 10^15        Cross multiply

6.02*10^23 x = 1 * 3.14 * 10^15             Divide by 6.02*10^23

x = 3.14*10^15 / 6.02*10^23

x = 0.000000005 mols

x = 5*10^-9

1 mol of CO has a mass of 28

5*10^-9 mol of CO has a mass of x                        Cross Multiply

x = 5 * 10^-9 * 28

x = 1.46 * 10^-7 grams

Answer: there are 1.46 * 10-7 grams of CO if only 3.14 * 10^15 molecules are in the sample

What process removes carbon dioxide from the ocean?
Katen [24]

Answer:

B. decay of dead marine organisms

Explanation:

When the temperature is low, carbon dioxide is captured by the oceans, and when the temperature is high, it is released by the oceans into the atmosphere. At sea, carbon dioxide feeds phytoplankton.

Most of the carbon dioxide consumed by plant plankton (phytoplankton) returns to the atmosphere when this phytoplankton dies or is consumed, but a portion is deposited in the ocean floor sediments when these small particles sink. This process is called a "biological bomb" because carbon dioxide is transported from the atmosphere to the ocean floor.

Para la siguiente reacción química demuestre que cumple con la Ley de la Conservación de la Materia. Recuerde que debe justifica
nikklg [1K]

Answer:

In this chemical reaction, which is considered irreversible, that is why the reaction arrow is ONE and unidirectional and not two in opposite directions, which means reversibility of the reaction.

In summary, if we look closely at the reaction, we observe that the stoichiometric values are balanced in the reaction, therefore there is THE SAME AMOUNT OF REAGENTS AS PRODUCTS.

This phenomenon has to be met in ALL CHEMICAL REACTIONS, the stoichiometric balance is essential for this reaction to be well expressed.

Why is stoichiometric balance so important? Why we indicate that we have the same amount of reagents as products, means that NOTHING IS LOST, EVERYTHING IS TRANSFORMED in the matter of the organic compounds that reacted.

Explanation:

Although if we observe the stoichiometric values well they are not correct with respect to oxygen, therefore it would be necessary to correct that in the chemical reaction, but above we briefly explain why the balancing of the reactions and the relationship they have with the conservation of the mass.

The law of conservation of mass indicates that mass is never lost, but is transformed, like energy, considering that it happens in terrestrial life.
