Does The element with the largest subscript in a formula have the largest percent by mass in the compound?
Sometimes, but not necessarily: The largest percent by mass in a compound is that of the element for which the product of the subscript and the atomic weight is highest. For example, there is more carbon than hydrogen by mass in CH4.
Do all pure samples of a given compound have the same percent composition?
A compound is a combination of two or more elements. These elements join together based on their molecular bonds. No two elements combine in the same percentage.
Is silicon dioxide the same as salt?
no "Silica, also known as silicon dioxide, is a compound made out of the two most abundant elements in the Earth's crust, silicon and oxygen (SiO2). Silica has three main crystalline varieties: quartz (by far the most abundant), tridymite, and cristobalite. Silica is the main constituent of more than 95 percent of rocks that comprise 59 percent of the earth's crust. Quartz makes up about 12 percent of the land surface and about 20 percent of the Earth's crust. The highest levels of silicon in humans are found in the skin and connective tissues. ....." and silica is the raw material for glass
Why ammonia is more toxic than urea?
Ammonia is more toxic than urea because it is a strong alkaline compound that can disrupt cellular processes and cause damage to tissues and organs. Urea, on the other hand, is a less toxic waste product that is more easily excreted by the body in urine.
What does a compound have in it?
A compound is two or more elements joined together.
Does uranium contains more than 90 percent of one compound?

Is water more than 70 percent of the body's tissues?
Yes, water makes up more than 70 percent of the human body's tissues. In fact, the average adult's body is composed of about 60% water by weight, but this percentage can be higher in infants and varies with different tissues. For instance, brain and heart tissues contain a higher water content, around 73% and 79% respectively. Overall, water is essential for numerous bodily functions, including temperature regulation and nutrient transport.
What is the percent composition of ammonium carbonate?
Ammonium carbonate has the formula (NH4)2CO3. To calculate the percent composition, you first find the molar mass of each element and then divide the molar mass of each element in the formula by the formula mass of the compound and multiply by 100 to get the percentage.
Differentiate between simple and compound tissues?
Simple tissues are composed of a single type of cell, whereas compound tissues are composed of more than one type of cell. Simple tissues perform basic functions like covering, protection, and support, while compound tissues have more specialized functions such as transporting fluids, providing strength, or storing nutrients.
