Several companies produce personal water filters that can travel anywhere. Such filters make any water safe to drink by removing

bacteria and other contaminants. However, they cannot filter heavy metals and viruses or remove salt. The filters are constructed of sturdy plastic and weigh just two ounces. They can be purchased in stores or online for about $20

Answer:

Follows are the solution to this question:

Explanation:

In this question, the given problem is used for secure accessing, drinkable water anywhere helps to solve personal filtered water. There are also both inexpensive and easy to access.  Its components used mostly for everyone's manufacturing are long-lasting. Instead of just endangering users, those who protect the other, are the potential benefits to overall outweigh the potential.

Consider each possible structure of carbon dioxide, c o 2. Determine whether the structure is correct and justify your decision.
Mrrafil [7]

This structure is correct due to the total number of bonds and electrons

We employ the octet rule, which states that all atoms in a compound are expected to follow, to check the accuracy of any chemical structure. The octet rule is precisely satisfied for each atom in the depicted structure of carbon IV oxide. The valence shell of each atom in the molecule is surrounded by eight electrons. We may thus infer that this structure is accurate given the total number of bonds and electrons since CO2 has sixteen valence electrons.

It possesses a negative charge of 1.602176634 coulombs, the basic unit of electric charge, which is comparable to its negative charge. The rest mass of an electron is 9.1093837015 10^-31 kg, or just 1/1,836 the mass of a proton. An electron is therefore considered to have practically negligible mass in comparison to a proton or neutron, and its matter is not taken into consideration when calculating an atom's mass number.

How many moles of the product fecl3 do you make, when 8moles of fe react with excess cl2
tatuchka [14]

To figure out questions related to reacting moles/masses, the first step is always to write a complete balanced equation.

2Fe (s) + 3Cl2 (g) → 2FeCl3 (s)

Since Cl2 is the excess reactant, and Fe is the limiting reactant, we can simply find the number of moles of the product by comparing the mole ratio of the limiting reactant to the mole ratio of the product from the equation.

From the equation, mole ratio of Fe:FeCl3 = 2:2 = 1:1, the number of moles of product is exactly the same as the number of moles of the limiting reactant, which makes it 8 moles.

Note that if the mole ratio is not 1:1, you have to do some calculations to make sure the no. of moles is balanced at the end. Which means, if the mole ratio happened to be 1:2, the no. of moles of the product would be 8x2=16 instead.

So, your answer is 8 moles.
