The phosphate ion has a formula of PO₄⁻³
It is visible that there is one phosphorus atom and four oxygen atoms. Moreover, we know that both phosphorus and oxygen are non-metallic elements, so the bonding that must be present between them is covalent bonding.
Finally, the charge of an ion is distributed over the entire ion so that it is stabilized. Thus, the answer is:
<span>It is composed of one phosphorus atom and four oxygen atoms covalently bonded together, and there is a –3 charge distributed over the entire ion</span>
Answer:
Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called <u>Stereoisomers</u>.
Explanation:
Stereoisomerism is a phenomenon in which molecules have same molecular formula but have different arrangement of atoms or group of atoms in space. It is further classified as;
i) Geometrical Isomerism:
In this class of isomerism the groups or atoms about the double bond occupies different region in space. It is also called as <em>cis-trans </em>isomerism.
ii) Optical Isomerism:
In this class the molecules having same molecular formula differ in their interaction towards plane polarized light.
Answer: The answer is C
covalent bonds have a lower melting and boiling point

<span>the balanced equation for the reaction is as follows
2C</span>₄H₁₀ + 13O₂ ---> 8 CO₂ + 10H₂<span>O
stoichiometry of C</span>₄H₁₀ to O₂ <span>is 2:13
stoichiometry applies to the molar ratio of reactants and products. Avagadros law states that volume of gas is directly proportional to number of moles of gas when pressure and temperature are constant.
Therefore volume ratio of reactants is equal to molar ratio, volume ratio of C</span>₄H₁₀ to O₂<span> is 2:13
2 L of </span>C₄H₁₀ reacts with 13 L of O₂<span>
then 100 L of </span>C₄H₁₀<span> reacts with 13/2 x 100 = 650 L
therefore 650 L of O</span>₂<span> are required </span>
