Nitrogen is the most abundant element in the atmosphere, making up about 78%. Next is oxygen (21%), followed by argon (0.9%).
Oxygen is approximately 21% of the air we breathe.
Nitrogen makes up approximately 78% of Earth's atmosphere.
The Earth's atmosphere is composed of approximately 78% nitrogen. This means that nitrogen makes up the majority of the volume of the air we breathe.
Bronze is not a compound; it is an alloy. Bronze is made by combining copper with other metals such as tin, aluminum, or lead. Alloys are mixtures of two or more elements, where the atoms of one element are mixed with atoms of another element.
To find the percentage of KCl in the mixture, we first need to determine the percentage of potassium coming from KCl. Since the mixture is 44.20% potassium by mass and KCl is 74.55% potassium by mass, we can set up a simple ratio to find the percentage of KCl in the mixture as (74.55% / 100%) * 44.20% = 32.97%. Therefore, the percentage of KCl in the mixture is approximately 32.97%.
Nitrogen is the element that makes up approximately 79% of the air we breathe.
Oxygen is approximately 21% of the air we breathe.
Oxygen makes up about 21% of the air we breathe.
mainly nitrogen (approximately 78 percent) and oxygen (approximately 21 percent) there are approximately 1 percent other gases, which includes carbon dioxide at 0.04 percent (aprrox.)
The element that makes up about 70 percent of the air you breathe is nitrogen. Nitrogen constitutes approximately 78 percent of Earth's atmosphere, making it the most abundant gas. The remaining components include oxygen, argon, carbon dioxide, and trace gases. Oxygen, while essential for human respiration, only accounts for about 21 percent of the atmosphere.
Silver ingots, as we normally see them, are usually essentially Pure Silver (element) with a very small percent of impurities alloyed (mixture.)
A homogeneous mixture, aka an alloy: it is made mostly of iron, but is 0.2 to 2.1 percent carbon.mixture
Nitrogen makes up approximately 78% of Earth's atmosphere.
Typically, the air you breathe is comprised of 18 to 21 percent Oxygen.
This is a homogeneous mixture, as the two components (water and acetic acid) are evenly distributed throughout the solution and cannot be easily distinguished.
Nitrogen makes up about 78% of the air we breathe, with oxygen making up around 21%.
Steel is not an element, but is a mixture we call an alloy. It is mostly iron with a bit of carbon in it; these are the primary ingredients. But it may also contain other elements to give it different characteristics. The carbon is in it at about one percent (ball park), while if we add something over about 11% chromium, we'll get stainless steel.
