The bond type in the substance is ionic bonding because, ionic compounds in their solid state are not conducting but the ions they furnish when dissolved in water conducts electricity.

Ionic compounds are formed between metals and nonmetals. Metals are electropositive and they can easily loss electrons to from cations. Metals donate electrons to the electron deficient non metals to achieve octet.

Ionic bonding is a strong electrostatic force between opposite charged ions. Hence this bond is stronger than other types of bond. This intact bonding make them bad conductors in the solid state.

However they are electrically conducting the molten state or when dissolved in water due to the presence of free ions and electrons in the solution.

Hey do you know if "horsleyjaydyn" is a girl you commented once she was a guy so

Explanation:

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.

Now, 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.

Use 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

Explanation:

If we add more SO2 gas to the reaction chamber. To the left. The reaction would drive

backwards to re-establish equilibrium (more reactants made).

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.

The dog would not  be in the part of first trophic level of an energy pyramid.

Energy pyramid is defined as a model that show the flow of energy from one tropic or feeding level to next tropic or feeding level in an ecosystem.

There are basically three energy pyramid.

Trophic level is defined as the source based on their nutrition or food, organisms occupy a specific place in a food chain.

First trophic level contains only green plants and producers. Their plants and product where consumed by second level of organisms.

Thus, the dog would not  be in the part of first trophic level of an energy pyramid.

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.

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.
