Chemistry
1 answer:
Montano1993 [528]3 years ago
8 0

It is a general test for the detection of halogens, nitrogen and sulphur in an organic compound. ... This is done by fusing the organic compound with sodium metal. The ionic compounds formed during the fusion are extracted in aqueous solution and can be detected by simple chemical tests.

I love your face

thx for the points

How many joules of energy would it take to raise the temperature of 2.5 grams of magnesium metal from
garik1379 [7]

Answer:

Q = 63.75J

Explanation:

Mass = 2.5g

Initial temperature (T1) = 25°C

Final temperature (T2) = 50°C

Specific heat capacity of Mg = 1.020J/g°C

Heat energy = ?

Heat Energy (Q) = mc∇T

Q = heat energy

M = mass of substance

C = specific heat capacity of substance

∇T = change in temperature = T2 - T1

Q = mc∇T

Q = mc(T2 - T1)

Q = 2.5 × 1.020 × (50 - 25)

Q = 2.55 × 25

Q = 63.75J

The heat energy required to raise magnesium metal from 25°C to 50°C is 63.75J

Calculate the Kelvin temperature to which 10.0 L of a gas at 27 °C would have to be heated to change the volume to 12.0 L. Units
KatRina [158]

Hello!

For this problem, we will be applying <em>Charles' Law</em>:

V1/T1 = V2/T2

Now that we have the formula, let's convert the temperature to Kelvin.

27 + 273 = 300K

Let's plug everything in now!

10/300 = 12.0/x

Simplified:

1/30 = 12.0/x

Cross-multiply:

1x = 30*12.0

<u>x = 360</u>

<em>Check!</em>

10/300 = 12/360

300*12 = 360*10

3600 = 3600

Therefore, you would have to heat the gas at a temperature of 360K in order to raise the volume to 12.0L.
