Why does the atomic radius decrease across a period

Chemistry
1 answer:
IgorC [24]3 years ago
4 0
Because the nuclear charge increases across a period and so it has a stronger pull on the outer electrons and will pull in the radius

If gravity is the ONLY force acting on an object, then the force of
Earth's gravity produces acceleration of 9.8 meters per second²
downward.  That number doesn't change, and it doesn't depend
on the mass or weight of the object.

If there are any other forces acting on the object at the same time,
like air resistance or some other kind of friction for example, then
all bets are off, and we can't say what the object's acceleration will
be in that case.

The _____ is the organelle that recycles unneeded molecules
Aneli [31]

Answer: Lysosomes

Explanation: The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.

prohojiy [21]

Answer:

<h2>2Al + 3CuO ==> 3Cu + Al2O3</h2>

Explanation:

So let's break this chemical equation down into 2 parts - Reactants and Products

Reactants = Al + CuO

Products = Cu + Al2O3

So the Chemical Reaction will be

Al + CuO ==> Cu + Al2O3

So the balanced equation will be,

2Al + 3CuO ==> 3Cu + Al2O3

There are on average 43 g of sugar and 355 mL can of soda please calculate the molarity of sugar in the can of soda the molar ma
vfiekz [6]

Explanation:

Given :

Amount of solute - sucrose (C12H22O11) = 41 g

Amount of solvent -soda  = 355-mL

Molarity of the solution with respect to sucrose= ?

Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.

Formula to find the molarity of solution :

               Molarity =  

Amount of solvent is given in mL, let’s convert to L :

               1 L = 1000 mL

Therefore, 355 mL in L will be :

                   

               = 0.355 L

We have the amount of solute in g, let’s calculate the number of moles first :

       Number of moles (n) =  

Molar mass of C12H22O11 = 342.29 g/mol.

Therefore, n =  

               = 0.119 moles.
