Which substance tends to form anions when bonding with other elements?
sodium
oxygen
argon
calcium
Answers
Answer:
B) Oxygen
Explanation:
i just took the test.
Any species that contain negative charge over it called anion. Out of sodium, oxygen, argon and calcium, oxygen is the only element that can form anion. So option B is correct option.
What are non metals?Non metals are the element that have property to gain electron. When any element gain electron then element attain negative charge and that element is called anion.
In our question sodium, argon belongs to metals category and these lie on the left side of the periodic table. Metals are meant to release electron and hence become cation.
Argon is non metal but it is a noble gas which has property to not to react as its octet is complete. Thus the only element that is non metal here is Oxygen that forms anion. Its oxidation state is -2. Thus option b is correct option

if one mole of na3po4·3h2o is heated extensively, how many moles of water are released?
Answers
When one mole of Na3PO4.3H2O is heated extensively, three moles of water are released.
The water molecules in Na3PO4.3H2O are called molecules of water of crystallization. These molecules are not covalently bonded to the Na3PO4 molecule. They are only loosely attached to the substance.
Strong heating will drive away these molecules of water of crystallization to give three moles of water in the product.
Hence, when one mole of Na3PO4.3H2O is heated extensively, three moles of water are released.

D. A cell that has a salt-bridge connection
Answers
Answer:
A. A cell with a negative cell voltage
Explanation:
other answer is wrong
An electrolytic cell is a cell with a spontaneous redox reaction (option B).
What is an electrolytic cell?Electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur.
An electrolytic cell converts electrical energy into chemical energy. The redox reaction in the cell occurs spontaneously and is responsible for the production of electrical energy.
Therefore, according to this question, option B is correct.

Answer:
relative proportions of the elements in a chemical reaction
A molecule or a compound can easily be represented by their formula.Subscripts in chemical formulas are used to indicate the relative proportions of the elements in a compound.
What is chemical formula?A chemical formula represent the identity and number of elements in a molecule or compound. Each element in periodic table has their own symbols. For example, hydrogen is H, oxygen having O, N for nitrogen, Na for sodium etc.
These chemical symbols are came from the first one or two letters of the Latin names of the elements. The number of these elements in a compound is given as subscripts of their symbols.
For example, there are two hydrogens and one oxygen in water and the formula is H₂O. Similarly the formula of carbon dioxide is CO₂ where one carbon and two oxygens are present. In this way the compounds can be easily identified and distuinguished using their chemical formulas.

Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16)
would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use "-" to represent a single
bond and "=" to represent a double bond) (1 point)
C-O-O
O=C-O
C=O-O
O=C=O
Answers
Answer: D
Explanation:
O=C=O
Carbon is in group 14 having four valence electrons and oxygen is in group 16 having six valence electrons hence the correct structure of CO2 is O=C=O.
Carbon and oxygen are nonmetals. Nonmetals form compounds by sharing electrons in a covalent bond.Carbon, a group 14 element has four valence electrons while oxygen, a group 16 element has six valence electrons.
Carbon can share four valence electrons with two oxygen atoms in CO2 to form the structure O=C=O. In this way, all the atoms now obey the octet rule.

Answer:
I think that it would be better to have smaller cells because smaller cells takes less energy to transport waste and generally more efficient to control than larger cells. It is better to have smaller cells because larger and fewer cells takes up more nutrients, but doesn't cover as many surface area. In the end, smaller cells are more efficient, cover more surface area, and moves faster than bigger cells.
