Eli states that sodium phosphate is a mixture because it is composed of both sodium ions and phosphate ions.

KonstantinChe [14]

Answer is: c. It is incorrect because sodium phosphate is a compound that has a single composition.

Sodium phosphate is chemical compound composed of atoms connected with chemical bonds.

Pure substance is made of only one type of atom (element) or only one type of molecule (compound), it has definite and constant composition with distinct chemical properties.

Pure substances can be separated chemically, not physically, that is difference between pure substances and mixtures.

If you have 1.00 mole of F2 at 1.00 atm of pressure and 0°C, what is the volume of F2?

ss7ja [257]

Answer:

$V=22.4L$

Explanation:

Hello,

In this case, by using the ideal gas equation, er can compute the volume of fluorine gas as shown below:

$PV=nRT\\\\V=\frac{nRT}{P}=\frac{1mol*0.082\frac{atm*L}{mol*K}+(0+273)K}{1.00atm} \\\\V=22.4L$

Best regards.

For the reaction, 2A + B → 3C, rate of disappearance of A is 0.3 M/s in a certain time interval.What is the average rate of appe

andrezito [222]

Answer:

E) rate of appearance of C = 0.45 M/s

rate of the reaction = 0.15 M/s

Explanation:

2A + B → 3C

Writing rate law for the reaction:

<u>Rate of reaction</u> = - $\frac{1}{2}$ $\frac{d[A]}{dt}$ = - $\frac{d[B]}{dt}$ = $\frac{1}{3}$ $\frac{d[C]}{dt}$ → equation 1

Given that the rate of disappearance of A is 0.3 M/s

⇒ - $\frac{d[A]}{dt}$ = 0.3 M/s

⇒Rate of reaction = - $\frac{1}{2}$ $\frac{d[A]}{dt}$ = $\frac{1}{2}$ ×0.3 M/s

⇒<u>Rate of reaction = 0.15 M/s</u>

From equation 1, $\frac{d[C]}{dt}$ = - $\frac{3}{2}$ $\frac{d[A]}{dt}$ = $\frac{3}{2}$ ×0.3 M/s

⇒ $\frac{d[C]}{dt}$ = 0.45 M/s

or <u>the rate of appearance of C = 0.45 M/s</u>
