Answer:

It can help change it's form.

Explanation:

The law of conservation of matter or mass, states that matter is neither created nor destroyed. But, you can change the form of matter based o Physical and/ or Chemical changes.

Let's take water as an example.  Water is a liquid, but you can always change water into a gaseous or solid form by using heat or cooling methods. When you heat water, the molecules move faster to make it form into a gas form...... You don't change it chemically, but physically. Same as the cooling process, only this time you are changing it into a solid.

Hope this helps :D

Answer:

The Law of Conservation of Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another. Another way to explain the law of conservation of matter is to say that things cannot be magically created or destroyed.

What is the wavelength of the line corresponding to n=4 in the balmer series? express your answer in nanometers to three signifi
liq [111]
Expression for the Balmer series to find the wavelength of the spectral line is as follows:
1 / λ = R (\frac{1}{2^{2} } -  \frac{1}{ n^{2}} )
Where, λ is wavelength, R is Rydberg constant, and n is integral value (4 here →  Fourth level) 
Substitute 1.097 x 10⁷ m⁻¹ for R and 4 for n in the above equation 
1 / λ = (1.097 x 10⁷ m⁻¹) (\frac{1}{2^{2} } -  \frac{1}{4^{2} }  ) 
   = 0.20568 x 10⁷ m⁻¹
λ = 4.86 x 10⁻⁷ m 
since 1 m = 10⁹ nm
λ = 486 nm

What is the pH of a solution with a concentration of 4.2 × 10–5 M H3O+? 2.31 4.38 5.62 6.87
Eva8 [605]
<h3><u>Answer</u>;</h3>

pH = 4.38

<h3><u>Explanation;</u></h3>

Consider that ;

[H3O+] = 10-pH mol/L  

 Therefore; the pH is the -log of the [hydronium ion].  

pH = - log [H3O+]

Thus;

pH = - log (4.2 × 10^–5)

     = 4.38

A student places three ice cubes in a beaker and allows them to partially melt. if she measures the temperature of the water in
atroni [7]

She will most likely observe that the temperature does not change during melting because the heat absorbed is used to overcome intermolecular forces rather than to increase the kinetic energy of the particles if she measures the temperature of the water in the beaker.
