Given what you observe at the molecular/atomic level, why would surface area have this effect?

Chemistry

LenKa [72]2 years ago
5 0

Answer:

Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.

How can u detect the which d-orbital is used in making bond ??
zavuch27 [327]
This is much more simple than it sounds... 

s has 1 orbital; p = 3 orbitals; d= 5 orbitals; f= 7 orbitals. (you just need to memorize this) 
A maximum of 2 electrons can occupy each orbital. 

<span>The number of orbitals that each atom has is based on the number of electrons it has and by consequence it's position on the periodic table. </span>

The orbitals occur in sequence. Whereby electrons fill first from the lowest energy level (1s) outwards to the highest. 
3p = the following sequence. 
1s, 2s, 2p, 3s, 3p: these 'sets' can hold the following electrons respectively (2+2+6+2+6) 18 which corresponds with argon on the periodic table. REMEMBER p has 3 orbitals, d has 5 orbitals. So, here there are 9 orbitals. 

The sequence through n=4 is: 

<span>1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f 
</span>

3. Ethanol has a density of 0.800 g/mL. <br> a. What is the mass of 225 mL of ethanol?
dedylja [7]

Since the ethanol has a density of 0.800 g/mL, the mass of the ethanol is 180 grams.

<u>Given the following data:</u>

  • Volume of ethanol = 225 mL
  • Density of lead ball = 0.800 g/mL.

To find the mass of the ethanol;

Density can be defined as mass all over the volume of an object.

Mathematically, the density of a substance is given by the formula;

Density = \frac{Mass}{Volume}

Making mass the subject of formula, we have;

Mass = Density \times Volume

Substituting the given parameters into the formula, we have;

<em>Mass of ethanol </em><em>=</em><em> 180 grams.</em>

How do tidal bulges form?
Troyanec [42]

Answer: The pull of the moon's gravity on Earth's water causes tidal bulges to form on the side closest to the moon and farthest from the moon. In the place where there are tidal bulges, high tide occurs along coastline.
