Which gas is 20 percent of the air you breathe?
Oxygen is approximately 21% of the air we breathe.
What element makes up approximately 78 percent of the earths atmosphere?
Nitrogen makes up approximately 78% of Earth's atmosphere.
What is the volume by percent of nitrogen?
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.
Why is bronze a compound?
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.
A mixture of KCl and KNO3 is 44.20 percent potassium by mass the percentage of kcl in the mixture is?
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%.
What element make up 79 percent of the air you breathe?
Nitrogen is the element that makes up approximately 79% of the air we breathe.
Which gas is 20 percent of the air you breathe?
Oxygen is approximately 21% of the air we breathe.
Oxygen composes approximately what percent of the air we breathe?
Oxygen makes up about 21% of the air we breathe.
The air you breathe in is in the?
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.)
What element is 70 percent of the air you breath?
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.
Is silver ingot a element or compound or homogeneous mixture or heterogeneous mixture?
Silver ingots, as we normally see them, are usually essentially Pure Silver (element) with a very small percent of impurities alloyed (mixture.)
Is steel a homogeneous or heterogeneous mixture or an element or compound?
A homogeneous mixture, aka an alloy: it is made mostly of iron, but is 0.2 to 2.1 percent carbon.mixture
What element makes up approximately 78 percent of the earths atmosphere?
Nitrogen makes up approximately 78% of Earth's atmosphere.
How much percent of oxgyen you breathe?
Typically, the air you breathe is comprised of 18 to 21 percent Oxygen.
Vinegar is composed of approximately 95 percent water and 5 percent acetic acid what type of mixture is this?
This is a homogeneous mixture, as the two components (water and acetic acid) are evenly distributed throughout the solution and cannot be easily distinguished.
What element makes up about 80 percent of the air you breath?
Nitrogen makes up about 78% of the air we breathe, with oxygen making up around 21%.
Is steel an element mixture or element?
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.
