Explanation:
You can view more details on each measurement unit: molecular weight of Na3PO4 or grams This compound is also known as Trisodium Phosphate. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Na3PO4, or 163.940671 grams.
b. neutrons
c. protons or neutrons
d. protons, neutrons or electrons
When neutrons are added to an atomic nucleus, energy is produced and this is called a fusion reaction. The answer is letter B. To be exact, two nuclei combine to produce a more stable nucleus. The positive charge on both nuclei result in a large electrostatic energy barrier to fusion.
The correct answer is c because the nuc are combing more protns and neutrons. The answer suposed to be protons and neutrons NOT PROTONS OR NEUTRONS?!!
b. larger urban heat islands
c. poor public health
d. a greater support capacity
A lack of sewage structures in overcrowded cities may lead to poor public health. Therefore, the correct option is C.
A sewage system, also known as a wastewater management system, is a system of pipes, pumping stations, and other accessories used to transport sewage from points of origin to points of treatment and disposal.
Combination sewers are systems that transport sewage from both domestic and storm sources. Due of the significant amounts of storm water that must be transported during wet weather conditions, combined sewers usually are made up of big pipes or tunnels. Public health may suffer in densely populated cities with inadequate sewage systems.

plasma
B.) sand & water
C.) Italian salad dressing
Answer:
The empirical formula of P4O10 is P2O5 . This is arrived at by dividing both subscripts by their highest common factor 2.
Explanation:
Empirical Formula of a compound is the lowest whole number ratio between the compound elements it is sometimes different from the standard formula of the compound).
The molecular formula is the formula derived from molecules and is representative of the total number of individual atoms present in a molecule of a compound.The empirical formula of the compound whose molecular formula is P₄O₁₀ is P₂O₅.
The empirical formula of a compound provides the simplest ratio of the number of various atoms present. It is an empirical formula if it has been simplified. The molecular formula is commonly used and is a multiple of the empirical formula.
Molecular Formula = n × Empirical Formula
On dividing both the subscripts of the formula P₄O₁₀ by 2 we get the empirical formula as P₂O₅.
