The compound, nah2po4, is present in many baking powders. what is its name? sodium phosphate sodium bephosphate sodium dihydroge
AlladinOne [14]
 The  compound NaH2PO4     name  is

sodium  dihydrogen  phosphate

 
Explanation
This name is    arrived  at  by using the   IUPAC rules  of naming   compound

1.  the metal (sodium)is  named  first  followed  by  the ligand ( hydrogen  and phosphate)

Ligand  are  molecules   that are   attached to  the metal  center.

2.   ligand  are  named using alphabetical   order(for  our  case  h  for hydrogen come before p for  phosphate hence hydrogen is named first)

3. Prefix   di is used  since hydrogen  are two

hence the name  of the compound  is  Sodium dihydrogen  phosphate

A gas has a pressure of 5.7 atm at 100.0°C. What is its pressure at20.0°C (Assume volume is unchanged)
son4ous [18]

Answer:

\large \boxed{\text{4.5 atm}}

Explanation:

The volume and amount of gas are constant, so we can use Gay-Lussac’s Law:

At constant volume, the pressure exerted by a gas is directly proportional to its temperature.

\dfrac{p_{1}}{T_{1}} = \dfrac{p_{2}}{T_{2}}

Data:

p₁ =5.7 atm; T₁ = 100.0 °C

p₂ = ?;          T₂ =  20.0 °C

Calculations:

1. Convert the temperatures to kelvins

T₁ = (100.0 + 273.15) K = 373.15

T₂ =  (20.0 + 273.15) K = 293.15

2. Calculate the new pressure

\begin{array}{rcl}\dfrac{5.7}{373.15} & = & \dfrac{p_{2}}{293.15}\\\\0.0153 & = & \dfrac{p_{2}}{293.15}\\\\0.0153\times 293.15 &=&p_{2}\\p_{2} & = & \textbf{4.5 atm}\end{array}\\\text{The new pressure will be $\large \boxed{\textbf{4.5 atm}}$}
