If one of the reactants in a reaction is Na2O, what is known about the products?
const2013 [10]

D. The products will have at least 2 Na atoms and 1 O atom.

<h3>Further explanation</h3>

If we refer to the law of mass conservation, which states that

<em>In a closed system, the masses before and after the reaction are the same </em>

then the number of atoms in the reactance will be the same as the number of atoms in the product

In this problem it is known that Na₂O is one of the reactants so that the product of Na atoms and O atoms will at least equal the number of atoms in the bond, namely 2 Na and 1 O

Like an example of this Na₂O reaction:

Na₂O + H₂O ⇒ 2 NaOH

Na : left =2, right = 2

O : left=2, right = 2

Which statement describes the energy involved in diffusion? Diffusion requires energy in all cases. Diffusion requires energy on
MArishka [77]

Answer:

Both b and d can be correct

Explanation:

Generally, diffusion does not require energy (<em>making option a wrong</em>) because it is the movement of particles from a region of high concentration to a region of low concentration hence diffusion moves particles in the direction of a concentration gradient. An example of this is the passive transport (for instance, uptake of glucose by a liver cell).

However, in some cases, when diffusion is against the concentration gradient (i.e when particles move from a region of low concentration to a region of high concentration), diffusion will require energy in a case like this (<em>making option c wrong</em>). An example of this is active transport (transport of protein called sodium-potassium pump which involves pumping of potassium into the cell and sodium out of the cell).

The explanation above shows that diffusion can require energy to move particles (in or out) of the cell through the cell membrane.

Suppose you start with one liter of vinegar and repeatedly remove 0.08 L, replace with water, mix, and repeat. a. Find a formula
Bumek [7]

Answer:

0.92^n

Explanation:

Given that :

Initial amount of vinegar = 1 Litre

Number of litres removed repeatedly = 0.08 Litre

Since the amount removed each time is constant, then ;

Initial % = 100% = 100/100 = 1

. Using the relation :

Amount of vinegar in mixture :

Initial * (1 - amount removed / initial amount)^n

n = number of times repeated

1 * (1 - 0.08/1)^n

1 * (1 - 0.08)^n

1 * 0.92^n

Hence,

For nth removal,

Concentration will be :

0.92^n ; for n ≥ 1

What is the difference between an atom an ion how to determine the charge
Eduardwww [97]

Explanation:

When an atom's outermost orbital gains or loses electrons (also known as valence electrons), the atom forms an ion. An ion with more protons than electrons carries a net positive charge and is called a cation. An ion with more electrons than protons carries a net negative charge and is called an anion
