You are given a sample of a Group II metal chloride, but the identity of the metal is unknown. Knowing that all Group II metal c
topjm [15]

Answer:

The identity of unknown substance is Barium.

Explanation:

The given compound has a formula of MCl2. And the percentage of chlorine in this compound is said to be 34.1 %. But, we know that the mass of chlorine in this compound is, 35.5*2 = 71 g

Therefore, if we let x be the total mass of the compound, then:

34.1% of x = 71 g

(0.341)x = 71 g

x = 71 g/0.341

x = 208.2 g

Hence, the mass of other atom M, must be:

M = x - 71 g

M = 208.2 g - 71 g

M = 137.2 g

Now, we look into periodic table in group II. We find that the element is Barium with atomic mass of 137 g.

<u>The identity of unknown substance is Barium.</u>

A sample of hexane (C6H14) has a mass of 0.580 g. The sample is burned in a bomb calorimeter that has a mass of 1.900 kg and a s
gulaghasi [49]
The answer is 27.7

According to this equation:
q = M C ΔT
When q= the energy that produced when there is a difference in temperature.
M (g) = amount of the material= 1.900 Kg= 1900 g
ΔT= difference in temperature ( in kelvin or C°)= 4.542 K
C= Specific heat capacity=3.21

∴ q = 1900 * 4.542 * 3.21 = 27701.7 J = 27.7 KJ
