The positive ion (cation) is written first.
The negative ion (anion) is written next.
The suffix is added at the end of the negative ion (anion). The suffix used is '-ide'.

As per question, the first word in the name of a binary ionic compound represent the positive ion and then the negative ion.

For example : NaCl is the binary ionic compound that composed of two different elements which are Na and Cl. The name of this compound is, Sodium chloride.

choli [55]

The least electronegative component in the electron transport chain is the Hydrogen ion.
The more electronegative is NAD+
The other component is H2O,
Next are the energy carrier molecules which are the ADP and ATP
And finally, the most electronegative is O2.

Si 100 monedas tienen una masa total de 226.13g. Cual es la masa de una moneda

galben [10]

The mass of a coin : 2.2613 g

<h3>Further explanation </h3>

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.

The main composition of algebraic expressions are:

1. phrases

algebraic forms separated by arithmetic operations

consists of one phrase (monomial) to many phrases (polynomial)

2. variables

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.

3. constants

is a fixed value, can be a number

4. arithmetic operations ⇒ +, - , : , x

<em>If 100 coins have a total mass of 226.13g. What is the mass of a coin</em>

We can make this statement in the form of an algebraic equation :

100 coins=226.13 g

then the mass of a coin :

$\tt \dfrac{1}{100}\times 226.13~g=2.2613~g$

Determine whether each substance will sink or float in corn syrup, which has a density of 1.36 g/cm3. Write “sink” or “float” in

kondor19780726 [428]

Answer:

Here's what I get

Explanation:

A substance with ρ < 1.36 g/cm⁻³ will float on corn syrup.

A substance with ρ > 1.36 g/cm⁻³ will sink in corn syrup

$\begin{array}{rrr}\textbf{Substance} & \mathbf{\rho/g\cdot \textbf{cm}^{-3}}& \textbf{Sink/Float}\\\text{Gasoline} & 0.75 & \text{Float}\\\text{Water} & 1.00 & \text{Float}\\\text{Corn syrup} & 1.36 & -\\\text{Honey} & 1.42 & \text{Sink}\\\text{Titanium} & 4.54 & \text{Sink}\\\end{array}$
