Answer:

Explanation:

Start by writing water as HOH

Ca(OH)2 +CO2 = CaCO3+ HOH

Next pay attention to the CO2 going to CO3

We need an oxygen.

Fortunately that is provided by the (OH)2

Now we have

Ca(OH)2 + CO2 ==> CaCO3 + HOH

and believe it or not, that is balanced as it is

The left side has 1 Ca. So does the right side

The Left side has 1 C. So does the right side.

The left side has 2 H. So does the right side

The left side has 2 oxygens (in Ca(OH2)) + 2 oxygens in CO2

So the equation is balanced.

a 22.44g sample of iron absorbs 180.8 J of heat, upon which the temperature of the sample increases from 21.1C to 39.0/ what is

NeX [460]

Answer:

The specific heat of iron is 0.45 J/g.°C

Explanation:

The amount of heat absorbed by the metal is given by:

heat = m x Sh x ΔT

From the data, we have:

heat = 180.8 J

mass = m = 22.44 g

ΔT = Final temperature - Initial temperature = 39.0°C - 21.1 °C = 17.9°C

Thus, we calculate the specific heat of iron (Sh) as follows:

Sh = heat/(m x ΔT) = (180.8 J)/(22.44 g x 17.9°C) = 0.45 J/g.°C

Does the density of ice affect the melting rate of ice, or does adding objects affect melting rates? I'm going to need evidence

kotykmax [81]

The density of ice does not affect the melting rate. But, adding an object does affect the melt rate. The reason this is is because when there is an object, there is less to melt. Hence, affecting the melting rate.

How many grams of kclo3 can be dissolved in 100 grams of water at 30 degrees Celsius

kondaur [170]

<span>The solubility of KClO</span>₃ : ( 10.1 / 100 g water ) at 30ºC

10.1 g ------------ 100 g ( H₂O )
? g ------------- 100 g ( H₂O )

Mass of KClO₃ :

100 * 10.1 / 100

1010 / 100 = 10.1 g of KClO₃

hope this helps!

Physical properties are those which can be measured or observed without changing the _______.

blsea [12.9K]

I’m not sure but I think the answer is substance . Because you can change the temperate of a substance but it will still be that substance . You can change all of these things except the substance itself
