Which would have more mass: a mole of sodium or a mole of copper? How do you know?
Answers
Answer:
copper
Explanation:
so for this you can work out the mass for both and compare
so mass = moles × mr
so mass of sodium = 1 × 23= 23 g
and mass of copper = 1 × 63.5= 63.5 g
so copper have more mass :)

state and explain the trends in the atomic radius and ionization energy for elements Li to Cs.
Answers
Explanation:
ionisation energy decrease down the group as the atomic radius increases. Nuclear charge increases. Number of shell increases so the electron will experience more shielding so it would be easier for the atom to loss electron.
The below table compares the number of electrons in two neutral atoms.
atom:
Ne 10

Compare the electron configuration and atomic radius of these two atoms and use that to explain the difference in their reactivity.

B. disminución de la presión de vapor
C. aumento de la presión de vapor
D. disminución del punto de congelación
Answer:
D
Explanation:
Esta pregunta recuerda las propiedades coligativas. Las propiedades coligativas son propiedades de sustancias que dependen de la cantidad de sustancia presente.
El punto de congelación es una propiedad coligativa. Se sabe que la presencia de impurezas reduce el punto de fusión y congelación. Esto se llama depresión del punto de congelación.
Por lo tanto, la observación registrada en la pregunta es el resultado de la disminución del punto de congelación.

Which diagram shows how the covalent bonds most likely form in a phosphorous trichloride molecule?
Answers
The first diagram shows the covalent bonds most likely form in a phosphorous trichloride molecule. Hence, option A is correct.
What is a covalent bond?Covalent bonds can be polar or nonpolar depending on the electronegativity difference between the atoms involved. In a nonpolar covalent bond, the electrons are shared equally between the atoms. In a polar covalent bond, the electrons are shared unequally.
Phosphorus trichloride (PCl₃) is a covalent compound that consists of one phosphorus atom and three chlorine atoms. The three chlorine atoms are located in a plane that is perpendicular to the phosphorus atom, forming an equilateral triangle with bond angles of 120°.
The molecule has a trigonal pyramidal shape, with the phosphorus atom at the apex and the three chlorine atoms at the base of the pyramid. The fourth hybridized orbital of phosphorus contains a lone pair of electrons that is located above the trigonal plane, giving the molecule a distorted tetrahedral geometry.
Thus, option A is correct.

Oxidation and reduction reactions (redox) involve the loss and gain of electrons. Half-reactions are a way for us to keep track of how many electrons are gained or lost by a particular species during a chemical reaction. These half reactions can be useful in understanding how batteries work, and how other reactions that occur in your body and in nature work as well. Questions 1. In the model, are electrons lost or gained during oxidation

7. A sample of a compound that contains only chlorine and oxygen reacts with excess hydrogen to produce 0.233 grams of hydrochloric acid and 0.403 grams of water. Determine the empirical formula of this compound.
Answers
Answer:
ClxOy + H2 > HCl + H2O
HCl = 0.233/37 = 0.006 mol H2O = 0.403/180.02 mol
HCl = 0.006/0.022 H2O = 0.022/0.006
= 1 = 4
Cl2O4 + 5H2 > 2HCl + 4H2O

Increasing the concentration increases the speed of reaction by... increasing the number of collisions between products increasing the amount of energy in the system increasing the number of collisions between reactants lowering the activation energy of the reaction
Answers
Answer: increasing the number of collisions between reactants
Explanation:
A reaction is possible due to collisions between the reactants to create products. If we increase the concentration of reactants then that means that we are increasing the molecules of the reactants which would give them more chances to collide and make products.
For instance, using a non-chemistry example, if there are few cars in a large city, the accidents there will be less because the cars will have such space that they wouldn't collide with each other. If the number of cars in the city is increased however, there is now less space and more chances for cars to collide.

The blood must keep moving round the body to keep the rate of diffusion high explains why
Answers
Answer:
red blood cells and diffusion.
Explanation:
this process involves red blood cells and diffusion. Red Blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs in to the RBC's, where it binds to hemoglobin.
Diffusion is a very important process within the human body and is essential to the transport of molecules within a number of organs including the lungs, kidneys, stomach and eyes. The lungs process millions of tiny air sacs that are called alveoli, each of which are in close contact with capillaries.
