Explanation:
Corrosion is a natural process that converts a refined metal into a more chemically stable form . It is the gradual destruction of materials by chemical
The kind of element that has the greatest tendency to attract electrons are inert gases or noble gases, in the right side of the periodic table. It is because the nuclear charge is bigger for the elements in the right side of the periodic table, and inert gases or noble gases' atom is the best to attract electrons.
Answer: 1687.19 g of and 1124,69 g of
Explanation:
We have the following reaction:
To use it, we must convert mass to moles of reactants, by diving each mass between the molar mass of the substance:
Now we must identify the limiting reactant, the one that will be totally consumed in the reaction. We take the one with fewer moles and calculate how much moles of the other ones are needed to consume it all, using a rule of three:
So there is enough and to consume the oxygen. In case there wasn´t enough of one of the other reactants, that one would be the limiting one.
Now, we can use the limiting reactant to calculate the moles of products obtained, again using a rule of three:
Lastly, we can convert moles to mass by multipling by the molar mass of each substance:
The significant zeros in the following numbers are given below;
- 0.000067800 - all zeros except the last two
- 3068800000 - all zeros
- 4000600.00 - all zeros except the ones after the decimal point
<h3>What are significant zeros?</h3>
Significant figures of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something.
To determine whether or not a zero in a number is significant or not, the following rules are applied:
- Non-zero digits are always significant
- Any zeros between two significant digits are significant
- A final zero or trailing zeros in the decimal portion only are significant
This suggests that the following applies to the following numbers;
- 0.000067800 - all zeros except the last two
- 3068800000 - all zeros
- 4000600.00 - all zeros except the ones after the decimal point

Answer:
Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions. Because the molecules are not moving, they're not able to form as many hydrogen bonds with other water molecules. Ice is a unique substance because it is solid-state — ice — is less dense than its liquid state. Because of this property, ice floats in water. Physical properties are characteristics of a substance. They do not change. Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions.
