Answer:

aluminum will lose 3 electrons.

Explanation:

to be stable and losing 3 is easier than gaining 5.

anddd its a metal. :)

Volume of water displaced = 94.60 cm3 Answer the following questions: Mass = g Density =

Contact [7]

We know that density is a measure of mass per unit of volume:
    Density = Mass / Volume

Therefore, we can calculate for the mass
    Mass = Density * Volume

if the density of water is 1 g/cm^3:
    Mass = Density * Volume
        = (1 g/cm^3) * 94.60 cm^3
          = 94.60 g

A 6.13 g sample of an unknown salt (MM = 116.82

Olin [163]

Answer:

-3.19x10³ J

Explanation:

Since the surroundings absorbed 3.19 × 10³ J (or 3190 J) of heat, the system, or the dissolution reaction, must have lost the same amount of heat. The heat for the system, then, is -3.19 × 10³ J (or -3190 J). We know this is true because of the first law of thermodynamics, "heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy".

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 8.10kg of water at 33.9 degree

Anuta_ua [19.1K]

Answer:

309.1K

Explanation:

Step 1: Convert the flown heat to Joule

We will use the relationship 1 kJ = 1,000 J.

$69.0kJ \times \frac{1,000J}{1kJ} = 69.0 \times 10^{3} J$

Step 2: Convert the mass of water to gram

We will use the relationship 1 kg = 1,000 g.

$8.10 kg \times \frac{1,000g}{1kg} = 8.10 \times 10^{3} g$

Step 3: Convert the initial temperature to Kelvin

We will use the following expression.

K = °C + 273.15 = 33.9°C + 273.15 = 307.1 K

Step 4: Calculate the final temperature

We will use the following expression.

$Q = c \times m \times (T_f - T_i)$

where,

Q: heat

c: specific heat capacity

m: mass

T f: final temperature

T i: initial temperature

$T_f = \frac{Q}{c \times m} + T_i = \frac{69.0 \times 10^{3}J }{4.18J/g.K \times 8.10 \times 10^{3}g} + 307.1K = 309.1K$
