What if when I find my product, I get the same compound as I did in my reactant? For example, FeCl3 + HCl ->FeCl3 + HCl. Then something is wrong. In this case, FeCl3 and HCl usually don't react. In very concentrated solutions of HCl, the FeCl4^- or FeCl6^-3 ion can form. In... There you go my friend

A car travels 90 meters north in 15 seconds. Then turns around and travels at 40 meters south in 5.0 seconds. what is the averag
Viefleur [7K]

Average velocity  =  (displacement) / (total time)

Displacement = distance and direction between
                             the starting point and the end point

The car travels 90 meters north, then 40 meters south. 
So it ends up 50 meters north of where it began. 

Displacement = 50 meters north
Total time  =  (15 + 5) = 20 seconds

Average velocity = (50 meters north) / (20 seconds)

                             =  2.5 m/s north

You drop an ice cube into an insulated flask full of water and wait for the ice cube to completely melt. The ice cube initially
3241004551 [841]

Answer:T=12.69^{\circ}C

Explanation:

Given

Mass of ice m=60 gm

mass of water M=760 gm

Initial Temperature of water T_i=20^{\circ}C

Let T be the Final Temperature of mixture

Latent heat of Fusion L=334 J/gm

heat required to melt ice completely is

Q_1=60\times 334=20.04 kJ

Heat released by water is taken by ice thus

Mc_{water}(20-T)=mL+mc_{water}(T-0)

0.76\times 4.184\cdot (20-T)=20.04+0.06\times 4.184\cdot (T)

T=12.69^{\circ}C

what is the density of a substance that has a mass of 2.0 g , and when placed in a graduated cylinder the volume changed from 70
lubasha [3.4K]

A material with a mass of 2.0 g when placed in a graduated cylinder the volume changed from 70 ml to 75 ml has a density of 0.4 g/mL.

How do I calculate the substance's density?

We'll start by getting the substance's volume. This is attainable as follows:

Water volume: 70 mL

75 mL = volume of material + water.

Substance volume =?

Substance volume equals (substance volume plus water) - (Volume of water)

Substance volume = 75 - 70

5 mL is the substance's volume.

Finally, we will calculate the substance's density. Below is an example to help:

2.0 g is the substance's mass.

5 mL is the substance's volume.

Substance density =?

Mass / volume equals density.

Substance density = 2/5

0.4 g/mL is the substance's density.

The density is therefore 0.4 g/mL.
