There are 2 possible correct answers. Those answers are A and C because atoms "fuse together" by sharing electrons, and both compounds react to water, as they both dissolve in it. I would choose C as my answer, though.

Answer:

The correct option is both compounds are held together by chemical bonds

Explanation:

Table sugar is an organic compound with the chemical formula C₁₂H₂₂O₁₁. Like every other organic compound, the carbon atoms (that carry the hydrogen atoms and the functional groups) are held together by covalent bond.

Table salt (NaCl) is a compound held together by ionic/electrovalent bond. The sodium atom (Na) transfers its valence electron to become sodium ion (Na⁺) while the chlorine atom (Cl) receives this valence electron to become chloride ion (Cl⁻). This type of bonding is known as ionic bonding.

From the above, it can be deduced that both compounds are held together by chemical bonds.

NOTE:

  • Both compounds <u>do not have the same density</u> as they have different masses
  • They dissolve in water to form solution but the table sugar does not react with water. The table salt will react in water so that its ions can separate and move freely in the water. The table sugar <u>does not react with water.</u>
  • Table salt <u>does not contain carbon</u>; it contains sodium and chlorine only.

grigory [225]

Answer:

2C2H2 + 5O2 -----> 4CO2 + 2H2O

Explanation:

The question is incomplete, but i manage to find one question similar to this, and the remaining part is:

C2H2 + O2 -----> CO2 + H2O

To balance the equation, we need to use the priority order to balance, which is the following:

Metals > non metals > Oxygen > Hydrogen

According to this, we have non metals, oxygen and hydrogen in the above equation, let's balance first the carbon. We have 2 carbons in the products, and 1 in the products, then, we just put a 2 there:

C2H2 + O2 -----> 2CO2 + H2O

Now, the number of carbon is balanced, but the number of oxygen was altered, let's see how much do we need. We have 5 oxygens in the products, and 2 in the reactants, we can put a 2 next to the water, so the sum of the oxygens in the products will be 6, and then, a 3 in the reactants:

C2H2 + 3O2 -----> 2CO2 + 2H2O

Putting that, will alter the number of hydrogens, so we need to balance that putting a 2 in the reactants; however this will alter again the number of carbons, so we must change the number in the products for the carbon, changing the 2 by a 4:

2C2H2 + 3O2 -----> 4CO2 + 2H2O

Finally, we can change the number of oxygens in the reactants, from 3 to 5, to balance the equation:

2C2H2 + 5O2 -----> 4CO2 + 2H2O

And this is the final balanced equation

Nitrogen and hydrogen can react to form ammonia. n2(g)+3h2(g)→2nh3(g) part a choose ratios showing the relationships between mol
Lelechka [254]
The ratio   that   show  the  relationship  between   moles  of   each    reactant  and   product  in  the  reaction  that  is

N2  +  3 H2  =  2NH3
 
the ratio  is  as  follows

1mole   N2 : 3 mol H2  :2mol  NH3

This  ratio  is  from  equation since  there  is  1  mole  of  N2  reacted  with 3  moles  of  H2  to  produce  2  moles  of  NH3

Consider the reaction of NO and CO to form N2 and CO2, according to the balanced equation: 2 NO (g) + 2 CO (g) → N2 (g) + 2 CO2
Gekata [30.6K]

The image is not given in the question, it is attached below:

<u>Answer:</u> The excess reactant is NO, the limiting reactant is CO and the products are shown in the image attached below.

<u>Explanation:</u>

In the given image:

Red spheres represent oxygen atoms, blue spheres represent nitrogen atoms and black spheres represent carbon atoms

The combination of 1 black and 2 red spheres will represent carbon dioxide (CO_2) compound

The combination of 2 blue spheres will represent nitrogen molecule (N_2)

The combination of 1 blue and 1 red sphere will represent nitrogen monoxide (NO) compound

The combination of 1 black and 1 red sphere will represent nitrogen monoxide (NO) compound

Limiting reagent is defined as the reagent which is completely consumed in the reaction and limits the formation of the product.

Excess reagent is defined as the reagent which is left behind after the completion of the reaction.

We are given:

Given moles of NO = 6 moles

Given moles of CO = 4 moles

For the given chemical equation:

2NO(g)+2CO(g)\rightarrow N_2(g)+2CO_2(g)

By stoichiometry of the reaction:

If 2 moles of CO reacts with 2 moles of NO

So, 4 moles of CO will react with = \frac{2}{2}\times 4=4mol of NO

As the given amount of NO is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.

Thus, CO is considered a limiting reagent because it limits the formation of the product.

Hence, the excess reactant is NO, the limiting reactant is CO and the products are shown in the image attached below.

. A scientist placed a sample of lithium into a container of water. The scientist observed the lithium floating and making a buz
Alex73 [517]

Answer: The conclusion that best support the observation is that (A CHEMICAL CHANGE took place).

Explanation:

A chemical reaction is defined as the process by which two or more substances, which are often referred to as REACTANTS, combine through bond formation or dissociation of bonds to form new PRODUCTS. In this type of reaction, a CHEMICAL CHANGE occurred because a new substance is formed as a result of the chemical reaction that took place.

There are different characteristics of a reaction which shows that a chemical change has occurred, these includes:

--> Color Change

--> Production of an odor

--> Change of Temperature

--> Evolution of a gas (formation of bubbles)

-- Precipitate (formation of a solid)

From the chemical reaction in the given question, Lithium metals reacts slowly with water to form a colourless solution of lithium hydroxide (LiOH) and hydrogen gas (H2). Here we observe that the buzzing sound of formed gas bubbles shows that a gas was given off. Therefore in conclusion, a CHEMICAL CHANGE took place.
