You are testing an unknown liquid to determine its identity. First you heat the liquid and find that it turns to gas at 80 degre

es Celsius. Then you add sodium to a small amount of the liquid to see if it reacts.Last you try to burn the liquid to see if it is flammable.
Which physical property of the
liquid did you test?

A. boiling point
B. ability to conduct electricity
C. combustibility
D. melting point

How many mL of water would be displaced by 408 g of lead?
Galina-37 [17]

Answer:

36 mL of water can be displace by the 408 g lead

Explanation:

Given data:

Mass of lead = 408 g

Volume of water displaced by lead = ?

Solution:

The volume of water displace by the lead would be equal to the given volume of lead.

So we will calculate the volume from given mass of lead from density formula.

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Density of lead is 11.36 g/cm³.

d = m/v

11.36 g/cm³ = 408 g/ v

v = 408 g/ 11.36 g/cm³

v =36 cm³

1 cm³  = 1 mL

volume = 36 mL

36 mL of water can be displace by the 408 g lead.

OFFERING 50 POINTS
tigry1 [53]

Answer:

The volume will be 2600 L.

Explanation:

Initial temperature (T_{1}) = 25°C = (25 + 273) K = 298K

Final temperature (T_{2}) = 54°C = (54 + 273) K = 327 K

By using the combined gas law equation,

                                 \frac{P_{1} V_{1} }{T_{1} } = \frac{P_{2} V_{2} }{T_{2}  }

                       or, \frac{760* 1200}{298} = \frac{380* V_{2} }{327}

                      or, 3060 × 327 = 380 × V_{2}

                      or, V_{2} ≈ 2600 L

Hence the volume of the balloon will be about 2600 L.

Major species present when dissolved in water ammonium iodide
Yuri [45]
Ammonium iodide, or NH₄I, is a salt. Since all salts are strong electrolytes, when ammonium iodide is dissolved in water, it would dissociate into ammonium ions and iodide ions. Hence, the major species present would be: <em>NH₄⁺ and I⁻ ions</em>.
