5 0
The  wavelength  of  a sound  wave  moving  at 340  m/s  and   with  a frequency of  256  Hz   is  calculated using the  the below  formula

wavelength =  speed  of the  wave/frequency

speed  of  the  wave = 340 m/s
frequency = 256 Hz

wavelength  is therefore =  340/256 =  1.32 m

Explain why landscapers might sift soil<br> that they use to construct gardens.
Studentka2010 [4]

Answer:

When one desires to remove debris from the garden then a soil sifter can be used as a beneficial tool. Based on the needs, it can be of different kinds. A landscaper may sift soil that they use at the time of constructing gardens due to many reasons:  

1. The soil becomes aerated, and thus, turn soft and easy to work upon.  

2. Sifting the soil makes the work of withdrawing undesired substances from the soil easy.  

3. It helps the plants to grow much better as the roots possess the tendency to penetrate more easily through the soil.  

4. The soil becomes healthy due to shifting, thus, helps in producing a beautiful and healthy landscape.

What's the oxidation number of Li in LiNO3
Studentka2010 [4]

+1

Explanation:

To solve this problem, we need to set up an algebraic equation. Let us first understand the meaning of oxidation number.

The oxidation number is the formal charge assigned to an atom present in a molecule or formula unit

The algebraic sum of all oxidation numbers of atoms in an ion containing more than one kind of atom is the charge on the ion.

The algebraic sum of all oxidation number of atoms in a neutral compound is zero;

   The radical NO₃ has a formal charge of -1;

 let the oxidation number of Li = x

 x + (-1) = 0

  x = + 1

What must break in order for water to change from solid to liquid to gas? what must break in order for water to change from soli
Step2247 [10]

Answer:

hydrogen bonds between water molecules

Explanation:

The hydrogen bonds between water molecules conditions the bulk of its physical property most especially its relatively high boiling point. The hydrogen bond results from the attraction between the oxygen of a water molecule and the hydrogen of another water molecule. The more electronegative oxygen atom causes a distortion and the attraction leads to a strong intermolecular bond between atoms of the water molecules.

Hydrogen bond is a very strong bond and it is responsible for the physical properties of water.
