How does freezing affect the volume of water?
MrRissso [65]

Increases the volume of water

Explanation:

Freezing of water causes the volume of water to increase by a whooping 4%. This is why the density of water is slightly different that of ice.

When ice freezes it expands and takes up more volume of space for the same mass given.

This is why bottles break when water in them is frozen.

This increase in volume is why ice floats on water. It makes it less dense.

A first-order decomposition reaction has a rate constant of 0.00440 yr−1. How long does it take for [reactant] to reach 12.5% of
mina [271]

Answer:

473 year

Explanation:

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

Where,  

[A_t] is the concentration at time t

[A_0] is the initial concentration

Given:

To reach 12.5% of reactant means that 0.125 of [A_0] is decomposed. So,

\frac {[A_t]}{[A_0]} = 0.125

t = ?

\frac {[A_t]}{[A_0]}=e^{-k\times t}

0.125=e^{-0.00440\times t}

t = 473 year

Select the atomic models that belong to the same element.<br> Sign out<br> INTL
Allushta [10]

Answer:

Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes. For example, most hydrogen atoms have a single proton in their nucleus.
