Answer:

The heat does a titanium block absorb is 204 J.

Explanation:

We have,

Mass of titanium block is 15 g

Initial temperature is 40° C and final temperature is 65° C.

Specific heat of titanium is 0.544 J/g C

It is required to find the heat does a titanium block absorb. The heat absorbed by the block is given by :

$Q=mc\Delta T\\\\Q=15\times 0.544\times (65-40)\\\\Q=204\ J$

So, the heat does a titanium block absorb is 204 J.

A specific brand of gourmet chocolate candy contains 7.00 g of dietary fat in each 22.7-gpiece. How many kilograms of dietary fa

Genrish500 [490]

Answer: 0.14 kg

Explanation:

Gourmet chocolate candy contains 7.00 g of dietary fat in each 22.7-g piece

That is 1 piece of candy weighs 22.7 g and contains 7.00 g of dietary fat

Converting the mass in pounds to kg

1 lb = 0.45 kg = 450 grams (1kg=1000g)

Number of pieces = $\frac{450}{22.7g}=20pieces$

1 piece contains = 7 g of dietary fat

Thus 30 pieces would contain = $\frac{7}{1}\times 20=140g$ of dietary fat

1 g = 0.001 kg

Thus 140 grams = $\frac{0.001}{1}\times 140=0.14kg$

Thus 0.14 kg of dietary fat are in a box containing 1.00 lb of candy.

Consider a 0.10 M aqueous benzoic acid, CeHeCOOH. The K benzoic acid. 6.5 x 10 for A) Write a balanced equation that shows the r

7nadin3 [17]

Answer:

a) C6H5COOH + H2O ↔ H3O+ + C6H5COO-

b) [ H3O+ ] = 2.517 E-3 M

c) pH = 2.599

Explanation:

a) balanced equation:

C6H5COOH + H2O ↔ H3O+ + C6H5COO-

⇒ Ka = ( [ H3O+ ] * [ C6H5COO- ] ) / [ C6H5COOH ] = 6.5 E-5

mass balance:

0.10 m = [ C6H5COO- ] + [ C6H5COOH ].....(1)

charge balance:

[ H3O+ ] = [ C6H5COO- ] + [ OH- ] .......[ OH- ] : comes from water, it's not significant

⇒ [ H3O+ ] = [ C6H5COO- ] .........(2)

b) (2) in (1):

⇒ 0.10 M = [ H3O+ ] + [ C6H5COOH ]

⇒ [ C6H5COOH ] = 0.10 - [ H3O+ ]

⇒ Ka = [ H3O+ ]² / ( 0.1 - [ H3O+ ] ) = 6.5 E-5

⇒ [ H3O+ ]² + 6.5 E-5 [ H3O+ ] - 6.5 E-6 = 0

⇒ [ H3O+ ] = 2.517 E-3 M

c) pH = - log [ H3O+ ]

⇒ pH = - Log ( 2.517 E-3 )

⇒ pH = 2.599
