Answer is Humus
Explanation:
Heavy metals are located on the lower part of the periodic table, specifically in the d-block and f-block elements.
In the periodic table, heavy metalsare found in the d-block and f-block, at the bottom. Elements in the d-block, or transition metals, span groups 3 through 12 in the periodic table. Metals like iron, copper, and zinc are included in this category.
The f-block elements, which comprise the lanthanides and actinides, may be found at the very end of the periodic table and are referred to as the inner transition metals. Due to their large atomic weights and high densities, elements like uranium and plutonium are classified as heavy metals.

B) calcium
C) copper
D) potassium
Answer:
B
Explanation:
The color of the emitted light depends on the energy. According to the arrangement of the electromagnetic spectrum, the color red has the lowest energy, the lowest frequency, and the largest wavelength
picks up CO2 and O2
picks up O2 and releases CO2
releases O2 and CO2
Answer:
picks up O2 and releases CO2
Explanation:
The pulmonary artery represents a structure within pulmonary circulation that is responsible for carrying deoxygenated blood to the lung.
When blood from the pulmonary artery reaches the long, it becomes oxygenated an in return, the CO2 it carries is released into the lung in a process otherwise known as gaseous exchange.
What happens to the blood that reaches the lungs from the pulmonary artery? The blood that reaches the lungs from the pulmonary artery picks up O2 and releases CO2. The rest of the choices do not answer the question above.
B. nitrogen chlorate
C. ammonium chloride
D. ammonium chlorate
The correct IUPAC name for the compound NH₄Cl is ammonium chloride as it has ammonia as its constituent.
A compound is defined as a chemical substance which is made up of identical molecules which contains atoms from more than one type of chemical element.
Molecule which consist of atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding which are present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are held by ionic bond.
3)Inter-metallic compounds where atoms are held together by metallic bonds
4) co-ordination complexes where atoms joined are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds. Compounds usually have different properties as those of elements because when a compound is formed the properties of the substance are totally altered from the elements.
