Molar mass Li2CO3 = 73.89 g/mol
Molar mass Li = 6.94g/mol Li = 6.94*2 = 13.88g
% LI = 13.88/73.89*100 = 18.78% perfectly correct.
Answer:
HCO₂
Explanation:
From the information given:
The mass of the elements are:
Carbon C = 26.7 g; Hydrogen H = 2.24 g Oxygen O = 71.1 g
To determine the empirical formula;
First thing is to find the numbers of moles of each atom.
For Carbon:
For Hydrogen:
For Oxygen:
Now; we use the smallest no of moles to divide the respective moles from above.
For carbon:
For Hydrogen:
For Oxygen:
Thus, the empirical formula is HCO₂
Answer:
The answer to your question is: Nuclear fussion
Explanation:
In Chemistry there are 2 nuclear processes:
Nuclear fission: is the process in which the nucleus of a radiactive element splits into two smaller nucleus, or two elements woth lower atomic number.
Nuclear fussion, is a reaction is which to small nucleus combine to form a heavier element.
Workplace labels are not required to include borders or particular language, but they do need the following details: Product identification data for the product's secure handling.
<h3>What does "label" mean in chemistry?</h3>
Labels are a suitable set of written, printed, or graphic informative components about a hazardous chemical some of which are attached to, printed on, or fastened to the adjacent container of something like a hazardous chemical but rather to the outside packaging, as defined by the HCS.
<h3>What are a label and a standard?</h3>
In order to give the customer the ability to make an educated decision regarding the potential for energy savings—and consequently, cost savings—of the relevant marketed product, the Bureau the Energy Efficiency launched this same Standards & Branding programme for appliances and appliances in 2006.
