Option B is correct. Phosphates are formed when phosphorus reacts with Oxygen
A phosphate group is formed from the bonding of four oxygen atoms to a phosphorous atom. The chemical reaction is as shown:
P + O₄ -> PO₄
P is the symbol of phosphorus
O is the symbol of oxygen
When both elements combine, they form phosphates.
Hence we can conclude that Phosphates are formed when phosphorus reacts with Oxygen

Answer:
1. Covalent Bond
2. Ionic Bond
Explanation:
Covalent bonds are defined as the bond in which sharing of electrons takes place between atoms. The sharing of electrons is in equal number so that it form a stable balance of attraction and repulsion between atoms. In the given example of CO2 (first image) oxygen is sharing equal number of electrons with carbon to form a stable bond called covalent bond.
Ionic bonds are formed when valence electrons are transferred to other atoms and form oppositely charged ions. In ionic bond formation, the atoms that gain electrons become negatively charged and the atoms that loses electrons become positively charged. In the given example of Ca Cl2, Ca is also giving its 2 valence electrons to each Cl and there is no stable balance of attraction and repulsion between atoms.
Hence, the correct answer is:
1. Covalent Bond
2. Ionic Bond
When solid copper reacts with aqueous silver nitrate, the products are copper (II) nitrate and silver metal. How
many grams of silver would be produced from 83.94 grams of silver nitrate?
Answer:
This chemical equation means: One mole of solid copper plus two moles of aqueous silver nitrate produce one mole of copper(II) nitrate plus two moles of solid silver. This is a single replacement reaction in which the metal copper replaces the metal silver.

* i think i am right and i really hope so but please dont
count it against me babe.
explanation:
Individual hydrogen bonds are weak and easily broken; however, they occur in very large numbers in water and in organic polymers, creating a major force in combination. Hydrogen bonds are also responsible for zipping together the DNA double helix.
A hydrogen bond is formed when the positive end of one molecule is attracted to the negative end of another. The concept is similar to magnetic attraction where opposite poles attract. Hydrogen has one proton and one electron. This makes hydrogen an electrically positive atom because it has a deficiency of electrons.
A polar molecule is a chemical species in which the distribution of electrons between the covalently bonded atoms is not even. Some chemical species, such as chains of carbon molecules, share electrons equally and are said to be nonpolar molecules
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
How does a material get a positive charge?
Answer:
positive charge comes from having more protons than electrons; negative charge comes from having more electrons than protons charge is quantized, meaning that charge comes in integer multiples of the elementary charge e

b) Why is aluminium extracted using electrolysis and not carbon?
Answer:
Aluminum is more reactive than carbon so it must be extracted from its compounds using electrolysis.
Explanation:
Even though aluminum is more abundant than iron in the Earth's crust, aluminum is more expensive than iron. This is mainly because of the large amounts of electrical energy used in the extraction process.

How is the glucose level in the blood maintained? Which body system, organs, and hormones are used and what do they do?
Answer:
Explanation:
Insulin is an hormone used to regulate blood glucose, as it helps to maintain a balance. It allows for transport of glucose to organs such as liver.
The process of glucose regulation is a complex process. When food is eating glucose is absorbed into the bloodstream this happen from the gut and it raises the blood glucose level this causes insulin(hormone) to be released from the pancreas so glucose can move inside the cells and be used.
As glucose moves inside the cells, the glucose level inside the bloodstream returns to normal and insulin release slows down.
Glucose which is the main energy source used by cells is allowed to be taken up by muscles, liver and fat (adipose tissue) and use as a source of energy so they can function properly.
D. It ensures continued existence of the orga
