The difference is the no. of charges present in Carbon, meaning Carbon has different charges therefore Roman numerals are used to clarify the exact number.This makes balancing equations easier.
Also their names are different.
CO4 - Carbon tetroxide
CO2 - Carbon dioxide
Answer:
Option (3) southern states threatened to secede from the Union over the issue of slavery
Explanation:
By the 18th century, the United States faced a number of issues. For example, the slave trade was one of the issues that resulted in the state being brought into turmoil. This was because the United States was already divided into two - the Northern region and the Southern region. The Northern region was the one region that still held to slave trade despite it being abolished. The South, offered slaves freedom. Thus, the movement of he slaves from the North to the South was a major issue. Thus, the war was over the trade as the north though it was suffering due to the decrease in slave labor.
The molecular weight of sodium is 23gr/mol. There is 31.5g sodium react used for reaction. From the equation, you can conclude that for every 2 sodium atoms, there will be 1 H2 gas formed.
The number of the H2 gas molecule formed would be: (2/1) * 31.5g/(23g/mol) = 2.74 mol
In STP an ideal gas will have volume 22.4l/mol. The volume of H2 gas would be: 22.4 l/mol * 2.74 mol= 61.36 liters.
So we know that this amount of atoms is Avogadro's number - the number of atoms in 1 mole of a substance.
So then, using dimensional analysis, we can find the mass, in grams, of potassium.
First we must find the molar weight of potassium as found on the periodic table: 39.098g/mol
Then we can solve directly for mass:
Therefore, the amount of atoms you have given, in terms of mass, will equal 39.098g - if the answer requires significant figures, then the mass would be 39.1g of potassium.
If the person had clogged arteries and high blood pressure, then went on a healthy diet, the person would start losing weight. They would have a more stable blood pressure (since they are eating healthy foods, with less saturated fat) and the clogged arteries would look significantly better. He/she might lose her/his risk of developing diabetes, heart disease, cancer, etc. Most of her/his health issues would start to balance out if they started eating a diet low in saturated fat.
I hope this helps!
