What happens to water when it changes to ice?

Chemistry
2 answers:
Elenna [48]2 years ago

Answer:

Its density decreases.

Its volume increases.

Explanation:

There are two changes that happen:

Its density decreases.

Its volume increases.

When the density is less, this is why ice floats on water. Density is calculate by mass/volume. Now mass is same here as we have not added anything here, this means that volume must have changed. Hence, the volume increases that makes the ice less dense.

Density decreases that's why ice floats on water because it's less dense than water.

(WILL GIVE BRAINLIEST IF YOU ANSWER ALL 4) Chemistry
Kitty [74]

Answer:

See explanations

Explanation:

a. Molarity = moles/Volume in Liters = 5moles/2Liters = 2.5M in NaCl

b. Freezing Pt Depression

     1. Sprinkling salt on icy surfaces

    2. Using antifreeze in automobile cooling systems

    3. <em>Not an application </em>

    4. Using salt to make ice cream

c. pOH = -log[OHˉ] = -log(1x10ˉ¹⁰) = -(-10) = 10 => pH = 14 – pOH = 14 – 10 = 4

d. H₂O + NH₃ => NH₄⁺ + OHˉ => Bronsted Acid is H₂O  (proton donor)

Some one help me please I'm stuck Show using two conversion factors how you would convert from 0.020 kg into mg.
julia-pushkina [17]

Answer:

=2.0x10^4mg

Explanation:

Hello there!

In this case, when performing units conversions involving two proportional factors we need to make sure we first convert to the base unit and then to the target one; thus, since 1 kg = 1000 g and 1 g = 1000 mg, we set up the following expression:

=0.020kg*\frac{1000g}{1kg} *\frac{1000mg}{1g} \\\\=2.0x10^4mg

Best regards!
