Freezing points for water with freezing mixtures based on salt and ice: Ammonium Nitrate - Chrushed Ice or Snow in Water 1 part Ammonium Nitrate - 0.94 parts Ice/water : temperature -4 o C 1 part Ammonium Nitrate - 1.20 parts Ice/water : temperature -14 o C
Explanation:
Answer:
option b : O₉S₁₀
Explanation:
There are some points to name a covalent compound, according to that
number of atoms numbered as
**mono for one, di - for two tri for three and so on.
the name of the atom as
**carbon as carbide, sulfur as sulfide, oxygen as oxide, foulrine as flouro etc.
So,
Formula of Nonoxide decasulfide
Now Naming of the Chemical compound
Following are the explanations of terms
- Prefix nono is used for number ''9'' denoting to the number of atom
- Oxide used for oxygen
- deca is use for number ''10'' denoting to the number of atom
- Sulfide is used for Sulfur in a compound
So keeping the above points in mind
The right answer is
Option b : O₉S₁₀
Answer:
If a solution conducts electricity, it is positive evidence that solute dissolved in solvent is electrolyte.
Answer:
Before we go through this I ask you carefully read every thing I've listed out or it's not going to make sense for you.
The equation:
![2C_3H_7OH \ + \ 9O_2 \ ----> \ CO_2 \ + \ 8H_2O](https://tex.z-dn.net/?f=2C_3H_7OH%20%5C%20%2B%20%5C%209O_2%20%5C%20----%3E%20%5C%20CO_2%20%5C%20%2B%20%5C%208H_2O)
CO2 and O2 aren't reacting with each other. One is a product and the other is a reactant. You're probably asking for how much CO2 will be formed with 17 moles of O2. It's pretty simple.
First you have to find the mole to mole ratio of O2 to CO2 (look at their coefficients/numbers right in front of their names), the ratio is 9 : 6, so for every 9 of oxygen gas (O2), 6 of carbon dioxide (CO2) is made. We have 17 moles of oxygen so if we divide it by 9 (mole ratio of oxygen gas) and multiply it by 6, we will get the amount of CO2 produced.
<u>(17/9) x 6 ≈ 11.3 moles of CO2 are made. </u>
In the case that you actually meant to say C3H7OH (Propanol) reacting with oxygen, I'll write that down here too:
The mole to mole ratio of Propanol to Oxygen gas is 2 : 9 (look at the coefficients) so we divide 17 moles of oxygen by 9 and then multiply it by 2, which will give us the amount of Propanol needed.
<u>(17/9) x 2 = 3.78 moles of Propanol is required to react with oxygen.</u>
