State relationship between the level of dissolved oxygen and water temperature
Artemon [7]
More dissolved oxygen is present in water with a lower temperature compared to water with a higher temperature. The reason for this inverse relationship between dissolved oxygen and temperature is that the solubility of a gas in a liquid is an equilibrium phenomenon.

Please help with word equations?
Delvig [45]
For the answer to the questions above, 

a) Ag2CO3(s) => Ag2O(s)+CO2(g) 

<span>b) Cl2(g)+2(KI)(aq) => I2(s)+2(KCl)(aq) (coefficients are for balanced equation) </span>
<span>net ionic is Cl2(g)+2I- => I2(s)+2Cl-(aq) </span>

<span>c) I2(s)+3(Cl2)(g)=>2(ICl3)

A 70.0-g piece of copper metal at 54.0 °C is placed in 50.0 g of water at 26.0 °C. If the final temperature of the water and met
KatRina [158]

The specific heat in, J /g °C of copper is 0.386J/g°C

HOW TO CALCULATE SPECIFIC HEAT CAPACITY OF A SUBSTANCE:

  • The specific capacity of a substance can be calculated using the following formula:

Q = m × c × ∆T

Where;

Q = quantity of heat absorbed or released (J)

m = mass of substance (g)

∆T = change in temperature (°C)

c = specific heat capacity (J/g°C)

For a colorimeter, the following equation applies:

m.c.∆T (water) = - m.c.∆T (metal)

  • For water:

m = 50g

c = 4.184 J/g°C

∆T = 29.2 - 26°C = 3.2°C

  • For copper:

m = 70g

c = ?

∆T = 29.2 - 54°C = -24.8°C

m.c.∆T (water) = - m.c.∆T (metal)

50 × 4.184 × 3.2 = -(70 × c × -24.8)

669.44 = 1736c

c = 669.44 ÷ 1736

c = 0.386J/g°C

Therefore, the specific heat in, J /g °C of copper is 0.386J/g°C
