Answer:
i am unique and have a specific number in the periodic table
To cut this short and for your understanding, ionic bond is formed between metals (mostly right column in periodic table). Covalent bond is formed between non-metals (mostly left column in periodic table). So polar covalent is also a covalent bond but it is polar, which means the shape of molecules are not symmetrical hence maybe an atom in a molecule has most of the electron attracted to it causing itself to be partial negative (since electron are negatively charged) and the other atom has its electron being attracted by others became partial positive. Polar covalent can also be when H atom is binding either to F, O or N (also known as hydrogen bond).
Answer:
<h2>8.5 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C)
From the question we have
![density = \frac{340}{40} = \frac{17}{2} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B340%7D%7B40%7D%20%20%3D%20%20%5Cfrac%7B17%7D%7B2%7D%20%20%5C%5C%20)
We have the final answer as
<h3>8.5 g/cm³</h3>
Hope this helps you
Answer:
They all contain switches
You have to use everything that is given since you have to know which is the limiting reactant. We find the limiting reactant by calculating the number of moles of each reactant and compare the number of moles. The limiting reactant would be the one that is consumed fully by the reaction.
