If a reaction produces 1.506 kJ of heat, which is trapped in 30.0 g of water initially at 26.5 C on a clorimetr liake hat in Fig

Dvinal [7]

<u>Answer:</u> The final temperature of water is 38.5°C

<u>Explanation:</u>

To calculate the amount of heat released or absorbed, we use the equation:

$q=mc\Delta T$

where,

q = heat absorbed = 1.506 kJ = 1506 J (Conversion factor: 1 kJ = 1000 J)

m = mass of water = 30 g

c = specific heat capacity of water = 4.184 Jl/g.°C

$\Delta T$ = change in temperature = $T_2-T_1=T_2-26.5^oC$

Putting values in above equation, we get:

$1506J=30g\times 4.184J/g.^oC\times (T_2-26.5^oC)\\\\T_2=38.5^oC$

Hence, the final temperature of water is 38.5°C

A certain substance X has a normal freezing point of -6.4 C and a molal freezing point depression constant Kf= 3.96 degrees C.kg

Brut [27]

Answer: $1.0\times 10^2g$

Explanation:

Depression in freezing point is given by:

$\Delta T_f=i\times K_f\times m$

$\Delta T_f=T_f^0-T_f=(-6.4-(13.6))^0C=7.2^0C$ = Depression in freezing point

i= vant hoff factor = 1 (for non electrolyte like urea)

$K_f$ = freezing point constant = $3.96^0C/m$

m= molality

$\Delta T_f=i\times K_f\times \frac{\text{mass of solute}}{\text{molar mass of solute}}\times \text{weight of solvent in kg}}$

Weight of solvent (X)= 950 g = 0.95 kg

Molar mass of non electrolyte (urea) = 60.06 g/mol

Mass of non electrolyte (urea) added = ?

$7.2=1\times 3.96\times \frac{xg}{60.06 g/mol\times 0.95kg}$

$x=1.0\times 10^2g$

Thus $1.0\times 10^2g$ urea was dissolved.

Answer:

What is a Metal ? Metals. Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the other elemental substances.

Explanation:

Metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal. ...

Definition: The non-metals are elements on the right of the periodic table
