Answer:
Cation / metal
Explanation:
When we named ionic compound we always write cation first. Let's take an example.
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations and ionic compound is formed. When we naming it we write " sodium " first which indicate sodium cation ( Na⁺) while anion which is Cl⁻ is always written at the end. When we naming ionic compound we ended the name of anion with "ide". Sodium indicate metal while chloride ion indicate non metal. it means metal comes first while naming ionic compound.

How many moles of NaCl are in 2.35 liters of a 4.67 M solution?
There are 10.97 moles of NaCl in 2.35 liters of a 4.67 M solution.
HOW TO CALCULATE NUMBER OF MOLES:The number of moles of a substance can be calculated by multiplying the molarity by the volume. That is;no. of moles = volume × molarity
According to this question, there are 2.35 liters of a 4.67 M solution. The number of moles is calculated as follows:no of moles = 2.35L × 4.67M
no of moles = 10.97mol
Therefore, there are 10.97 moles of NaCl in 2.35 liters of a 4.67 M solution.

what are the steps to naming simple ionic compounds
Answer:
To name an ionic compound, you simply need to find the names of the cation and anion present in the compound and make sure to revise the ends of metal names as needed. First, write out the name of the metal, followed by the name of the non-metal with its new ending.
Explanation:
Write the name of the cation, and then write the name of the anion, changing the ending to "-ide" if it's a single element and leaving it as it is if it's a polyatomic ion.

Elastic Potential Energy:
The work that needs to be done by any object is a form of energy. The work can be defined in terms of the work-energy theorem, which states that the work can either be the difference in the kinetic energy of a system or the difference in the potential energy of a system. There is a special type of potential energy reserved exclusively for

Work done : 19.5 J
Further explanationGiven
F = 15 N
d = 1.3 m
m = 3 kg

Solution
Work is the product of force with the displacement of objects.
Can be formulated
W = F x d
W = Work, J, Nm
F = Force, N
d = distance, m
Input the value :
W = 15 N x 1.3 m
W = 19.5 J

Boron carbonate decomposes into boron oxide and carbon dioxide, how many moles of carbon dioxide are produced when 5.0 mol of boron carbonate decomposes completely?
For the following elements (Group 1A), Li, Na, K, Rb), which atom is larger overall?
Answer:
The smallest atom you have listed would be lithium (Li).
Explanation:
Lithium is the third smallest atom listed on the periodic table of the elements. It has an atomic number of three, meaning it has three protons in it's nucleus.
Atom size (Atomic radius) increases from UP to DOWN in the same COLUMN(group) of the periodic table. For example, in the first group, the Atomic radius trend from smallest to greatest is: H (smallest) -- Li -- Na -- K -- Rb -- Cs -- Fr (greatest).
Reason is, the increasing energy level (increases from n=1 to n=7) causes the shielding effect increase dramatically. And since the size of atom is mostly consist of electrons, more energy level is filled, the larger the atom will be.)
However, in the same ROW from left to right, the atomic size decreases as the number increases. For example, Li #3, is larger than Flourine (F) with an atomic number 9 because they are on the same ROW.

What would be the mass of 3 moles of water molecules?
a
54 grams
b 40 grams
C
30 grams
d 20 grams
Answer:
[tex]\boxed {\boxed {\sf A. \ 54 \ grams }}[/tex]
Explanation:
To convert from moles to grams, we must use the molar mass.
Recall that water's molecular formula is H₂O. It contains hydrogen and oxygen. Look up the two elements masses on the Periodic Table.
Hydrogen (H): 1.008 g/mol Oxygen (O): 15.999 g/molNow, use these masses to find water's mass. The subscript of 2 tells us there are 2 atoms of hydrogen, so we multiply hydrogen's mass by 2 and add oxygen's.
H₂O= 2(1.008 g/mol) + 15.999 g/mol = 18.015 g/molUse the molar mass as a ratio.
[tex]\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]
Multiply by the given number of moles.
[tex]3 \ mol \ H_2O*\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]
The moles of water will cancel.
[tex]3 *\frac{18.015 \ g \ H_2 O}{ 1 }[/tex]
[tex]3 *{18.015 \ g \ H_2 O}[/tex]
[tex]54.045 \ g \ H_2O[/tex]
Round to the nearest whole number. The 0 in the tenth place tells us to leave the number as is.
[tex]54 \ g \ H_2O[/tex]
There are about 54 grams of water in 3 moles.
Answer:
54 grams
Explanation:
First step is to find what one mole of water is in grams.
Water is H2O so that means we have two moles of Hydrogen.
H - 2 grams (on periodic table)
We have one mole of Oxygen.
O - 16 grams (on periodic table)
Add 2 and 16 to get 18 total grams in one molecule of H2O
Now multiply 3 times 18 to know how many grams in 3 moles of H2O
You end with
3x18=54 grams
In the equation CH4 + 2O2 --> 2H2O + CO2 What is the mass of CO2 produced when 35g of O2 reacts?
Answer:
24.06 g of CO₂
Explanation:
The balanced equation for the reaction is given below:
CH₄ + 2O₂ —> 2H₂O + CO₂
Next, we shall determine the mass of O₂ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:
Molar mass of O₂ = 2 × 16 = 32 g/mol
Mass of O₂ from the balanced equation = 2 × 32 = 64 g
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32
= 44 g/mol
Mass of CO₂ from the balanced equation = 1 × 44 = 44 g
SUMMARY:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Finally, we shall determine the mass of CO₂ produced by the reaction of 35 g of O₂. This can be obtained as follow:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Therefore, 35 g of O₂ will react to produce = (35 × 44)/64 = 24.06 g of CO₂.
Thus, 24.06 g of CO₂ were produced from the reaction.
