What else can I help you with?
True or false Elements abundant in the body are not abundant on Earth?
False. Elements abundant in the body, such as oxygen, carbon, hydrogen, nitrogen, and calcium, are also abundant on Earth. These elements are essential for life and can be found in various forms in the Earth's rocks, atmosphere, and oceans.
The weights of all elements are always compared to oxygen. True False?
True. In chemistry, the weights of all elements are often compared to oxygen, specifically the isotope oxygen-16, which is used as a standard reference point for calculating atomic weights. This practice allows for a consistent and relative comparison of the masses of different elements.
Only 10 elements compose the bulk of the rock-forming minerals in the continental crust Is this true or false?
False. The bulk of the rock-forming minerals in the continental crust are composed of a variety of elements, not just 10. The most common elements found in these minerals include oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
Diatomic elements are generally stable when they are in molecular form true or false?
True. Diatomic elements, such as oxygen (O2), nitrogen (N2), and hydrogen (H2), are generally stable in their molecular form due to the strong bonding between the two atoms.
Diamond and quartz are both minerals composed of a single element true or false?
False. Diamond and quartz are minerals composed of multiple elements. Diamond is composed of carbon atoms, while quartz is composed of silicon and oxygen atoms.
True or False - Stars the size of the sun can produce elements heavier than oxygen.?
True
Elements abundant in the body are not abundant on Earth true or false?
False. Elements abundant in the human body, such as oxygen, carbon, hydrogen, and nitrogen, are also abundant in the Earth's crust.
True or false Elements abundant in the body are not abundant on Earth?
False. Elements abundant in the body, such as oxygen, carbon, hydrogen, nitrogen, and calcium, are also abundant on Earth. These elements are essential for life and can be found in various forms in the Earth's rocks, atmosphere, and oceans.
True or false most elements are nonmetal?
Most elements are metals.
The weights of all elements are always compared to oxygen. True False?
True. In chemistry, the weights of all elements are often compared to oxygen, specifically the isotope oxygen-16, which is used as a standard reference point for calculating atomic weights. This practice allows for a consistent and relative comparison of the masses of different elements.

Diatomic elements are generally stable when they are in molecular form true or false?
True. Diatomic elements, such as oxygen (O2), nitrogen (N2), and hydrogen (H2), are generally stable in their molecular form due to the strong bonding between the two atoms.
When elements combine to form compounds their properties do not change.?
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
Diamond and quartz are both minerals composed of a single element true or false?
False. Diamond and quartz are minerals composed of multiple elements. Diamond is composed of carbon atoms, while quartz is composed of silicon and oxygen atoms.
Ovaries do not produce testosterone true or false?
False
Organic compounds contain carbon atoms that are covalently bonded to other elements typically hydrogen and oxygen and other carbon atoms True or False?
true
Is it true that photosynthesis is the process by which earth's oxygen supply is diminished?
No, photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into energy and produce oxygen as a byproduct. It actually replenishes the Earth's oxygen supply rather than diminishing it.
