Answer:

Sort of answer, but it'll lead you in the right direction I hope.

Explanation:

I mean, ofc, the molecules or atoms or whatever the circles are can't be put together that way bc matter says so. It looks like the other diagram is showing water or gas, and if it were turning into the one on the right, then it would usually either settle into water if it was gas or become a single solid object like water. If this is gas, then it doesn't make sense, because gas particles are always separate from each other.

Answer:

Butane and benzene are both compounds. They contain multiple elements bonded together in a specific ratio. Kerosene and gasoline are mixtures because they are combinations of several compounds. Oxygen is an element because it is made up of only one type of atom.

Explanation:

The corresponding mRNA to 5'AAAACTGTGCAT3' is

3'UUUUGACACGUA5'.

Nucleotides are the bases that are arranged in a specific way, and it joins the two strands of DNA and RNA.

In DNA, four nucleotide bases are present AT and GC. They are attached to each other.

In RNA, the same bases are present but instead of T, U uracil is present.

When reading the DNA, the RNA bases complimentary join with the bases of DNA.

Thus, the corresponding mRNA sequence is 3'UUUUGACACGUA5.

2. 2Al(s) + 6HCl(aq) + 2AlCl3(aq) + 3H2(g) represents a single replacement reaction

A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds

Not all of these reactions can occur. We can use the activity series(voltaic series), which is a list of elements that can replace other elements below / to the right of them in a single replacement reaction.

1. 2Al(s) + 3Cl2(g) → 2AlCl3(s)

Syntesis/combination reaction

2. 2Al(s) + 6HCl(aq) ⇒2AlCl3(aq) + 3H2(g)

Single replacement reaction

3. 2AlCl3(s) → 2Al(s) + Cl2(g)

Decomposition reaction

4. AlCl3(aq) + 3KOH(aq) + Al(OH)3(s) + 3KCl(aq)

Double  replacement reaction

In a single replacement reaction, one element replaces another one. The reaction that shows the single replacement reaction is:

[tex]\bold { 2Al(s) + 6HCl(aq) \rightarrow 2AlCl_3(aq) + 3H_2(g)}[/tex]

[tex]\bold { 2Al(s) + 6HCl(aq) \rightarrow 2AlCl_3(aq) + 3H_2(g)}[/tex]

In the given reaction, aluminum replaces the hydrogen from hydrochloric acid to form Aluminum chloride.

Therefore, the reaction that shows the single replacement reaction is:

[tex]\bold { 2Al(s) + 6HCl(aq) \rightarrow 2AlCl_3(aq) + 3H_2(g)}[/tex]

Hello. You did not say what is the experiment to which this question refers, which makes it impossible for it to be answered accurately.

However, advice that should be given to anyone who should start an experiment is: establish a control treatment, provide all treatments with the same variables and the same resources, write down everything that happened in the experiment from implementation to data collection and results, make measurements and analyzes on the same date in all treatments and keep the steaks in the same environment.

Answer:

a. The density of the aluminum will change if the sample gets too big.

Explanation:

Since increasing its size increases its volume hence it affects the value of its density by decreasing.

note: Density = mass/volume.

Explanation:

An acid is a substance that ionizes to produce excess hydrogen ion in solutions.

Answer:

Concentration is a measure of how much solute (or dissolved "stuff") is present per amount of solvent (or dissolving liquid) in a solution. The most common measurement of concentration is molarity, abbreviated M. Molarity is expressed in amount per volume, or moles/liter.

Answer:

6.8 mole of O₂

Explanation:

Given expression:

       2H₂   +   O₂   →   2H₂O

Number of moles of H₂ = 13.6moles

Unknown:

Number of moles of O₂  = ?

Solution:

In the given problem, we are to find the number of moles of oxygen gas that will use up 13.6mole of hydrogen gas;

 From the reaction equation;

             2 mole of H₂ will completely react with 1 mole of O₂

         13.6 moles of H₂ will completely be used up by [tex]\frac{13.6}{2}[/tex] mole of  O₂

                                                                                        = 6.8 mole of O₂

Answer:

An ionic bond

Explanation:

They are most likely going to form an ionic bond.

An ionic bond is where atoms lose/gain electrons.

It is easier for elements in the first group to lose the one electron on their valence shell and for elements in the second group to take that.

Some examples are Sodium Chloride (NaCl) and Potassium Chloride (KCl)

Explanation:

check if one element replaces another element in a compound

The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.

The replacement reaction can be defined as the reaction in which the highly reactive element replaced the low reactive element in the reaction and forms a compound.

The reaction has been given as:

X + AY [tex]\rightarrow[/tex] AX + Y

The X has been highly reactive than Y replaces Y in the compound and forms the compound AX.

The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.

Put sand in one cup and water in the other. Put two heat lamps at equal height and under each one put the water and sand, this must be done at the same exact time. Set a timer for 5, then 10, then 15, and so forth minutes. Each time measure the temperature of each with the thermometers and write the down. Have a certain temperature you want them to get to and see which gets to it quicker. Then set a new temp 3 times to see if the answer is consistent.
