5 0

That acid rain has lowered the ph of a particular lake to ph 5.0. the hydroxide ion concentration of this lake is

1 × 10^-9 mol of hydroxide ions per liter of lake water

 pH  +  pOH  =  14

 pOH  =  14  - 5

 pOH  =  9.00

 pOH  =  -log [OH⁻]

[OH⁻]  =  10^-pOH

[OH⁻]  = 10^{-9} mol

Therefore,

the hydroxide ion concentration of this lake is 1 × 10^-9 mol

A 1.2 kg block of iron at 32 ∘C is rapidly heated by a torch such that 12 kJ is transferred to it. What temperature would the bl
lbvjy [14]

Answer:

For iron

Final temperature = 54,22°C

For copper

Final Temperature = 63.67 °C

Explanation

Hello,

You are using a torch to warm up a block of iron that has an initial temperature of 32°C.

The first you have to know is that the "heat capacity" could simply define as the heat required to go from an initial temperature to a final temperature.

So you need to use the heat capacity equation as follow in the paper.

The equation has to have all terms in the same units, so:

q = 12000 J

s = 0.450 J / g °C

m = 1200 g

Ti = 32 °C

Felicity lists the factors that affect the shape of Florida
umka2103 [35]
1. Humidity

2. Temperature

3. Rainfall

 In general, the electron pairs in a molecule that will adopt a shape to maximize their distance far apart, even charges repel each other as well as unlike charges attract,

 for example H2O has two lone electrons pairs but it adopts an angular shape. Hope this help!!

Convert 3841 cL to L. SHOW WORK PLS
barxatty [35]

Answer:

1 cl = 1 * 10-5 m³

1 L = 1 * 10-3 m³

1 L = 0.001 m³

1 m³ = (1/0.001) L

1 m³ = 1000 L

1 cl = 1 * 10-5 * 1000 L

1 cl = 0.01 L
