Answer:
N and P
Explanation:
Anion:
When an atom gain the electrons anion is formed. The negative sign shows that atom gain electron because number of electron are greater than protons or we can say that negative charge becomes greater than positive charge.
Cation:
When atom lose electron cation is formed. The atom thus have positive charge because number of positive charge i.e protons are increased are greater than negative charge or electron.
In given problem N and phosphorus both can gain three electrons which means negative charge becomes greater that's why the extra electron gained by atoms are written as -3 and both form anion with charge -3.
while Al form cation with charge +3 Mg form cation with charge +2 and iodine and bromine both form anion with charge of -1.
The answer should be A, flammability.
The isotopes of the same element would result in the same chemical properties, as the number of protons and electrons are not changed, meanwhile, the physical properties would be slightly different with each other because they have different numbers of electrons.
Out of the 4 options, only option A is a chemical property. Chemical properties are the properties of an element reacting with other substances that creates new substances at the end. While physical properties are the ones that does not produces new substances or any reactions. They are usually observable and measurable.
Therefore, since flammability is a chemical property, the answer is A.
Answer:
The correct answer is "D".
Explanation:
The synthesis consists of extracting the most important data from a text or any source of information. To be able to synthesize it is necessary to read, understand and interpret the message or arguments presented. Once these factors have been extracted, they are brought together to form a coherent text that in a few words explains the original text.
Have a nice day!
Answer:
Explanation:
H₂O(ℓ) ⟶ H₂O(g)
Data:
T = 25 °C
ΔG° = 8.6 kJ·mol⁻¹
Calculations:
T = (25 + 273.15) K = 298.15 K
Standard pressure is 1 bar.
