175 cm³ instead of 175 cm.

Answer:

297.5 cm³

Explanation:

From the question;

Initial volume; V1 = 175 cm³

Initial temperature; T1 = 25°C

Final temperature; T2 = 42.5°C

From Charles law we can find the volume V2 from the equation;

V1/T1 = V2/T2

Making V2 the subject gives;

V2 = V1 × T2/T1

V2 = (175 × 42.5)/25

V2 = 297.5 cm³

Answer: no

Explanation: because silicon cannot share over 3 bonds

Answer:

833.12g

Explanation:

Use the mole=mass/mr equation (rearrange this to find mass)

Mr= 164

So, 5.08 x 164 = 833.12g

The mass in grams of 5.08 mol Ca(NO3)2 is =833.12g

The mole is the amount of substance of a gadget which includes as many standard entities as there are atoms in zero.012 kilogram of carbon 12;

Molecular mass of Ca(NO3)2 = 40+(14+48)*2

                                                =40+124

                                                = 164 g

1 mole of Ca(NO3)2 = 164 g

5.08 mole of = 5.08*164g

                         =833.12g

Answer:

An atom of an element always contain three fundamental particles called electrons(e-) , neutron ( n zero) and protons ( p+)

An atom of an element always contains a proton, electron and neutron.

Every atom is made up of a nucleus and one or more electrons that are attached to the nucleus. One or more protons and a number of neutrons make up the nucleus. Only the most common type of hydrogen is neutron-free. Every solid, liquid, gas, and plasma is made up of atoms that are either neutral or ionized.

But when it comes to the word atom, we must go back to 400 B.C. Greece. And Democritus, a brilliant philosopher, proposed the Greek word atomos, which means uncuttable.

Every atom is made up of a nucleus and one or more electrons that are attached to the nucleus. One or more protons and a number of neutrons make up the nucleus.

Thus, An atom of an element always contains a proton, electron and neutron.

Answer:

CO is a chemical formula that contains one carbon atom (C) and one atom of oxygen (O). Altogether, CO translates to "carbon monoxide."

Explanation: Why monoxide and not dioxide? Well, the prefix mono means "one," and di means "two." Since there is only one oxygen atom (-oxide), then it must be monoxide! Voila!!

Answer:

The answer for this question is A. butylcyclohexane

Explanation:

Choose letter A

You welcome have a nice day.

Name of the given compound is butyl cyclohexane.

Cyclo alkanes are those organic compounds in which alkanes are present in the cyclic form.

In the nomenclature of cyclo alkane, name of the substitute is put before the name of the main ring. In the given structure number of carbons in ring is 6 so that given cycloalkane is cyclohexane and butyl group is attached as substitute. So name of the given compound is butyl cyclohexane.

Hence name of the compound is butyl cyclohexane.

Answer:

15.69 dozen

Explanation:

Mass of penny = 5 g

Dozens of penny =..?

Next, we shall convert 5 g to gross. This can be obtained as follow:

3824 g = 1000 gross

Therefore,

5 g = 5 g × 1000 gross / 3824 g

5 g = 1.3075 gross

Thus, 5 g is equivalent to 1.3075 gross.

Finally, we convert 1.3075 gross to dozen. This can be obtained as follow:

1 gross = 12 dozen

Therefore,

1.3075 gross = 1.3075 gross × 12 dozen / 1 gross

1.3075 gross = 15.69 dozen

Thus, 5 g of penny is equivalent to 15.69 dozen

the empirical chemical formula of X is CH4

Explanation:Step 1: Imagine you have a sample of compound weighing exactly . Multiply the mass of this sample by the mass percents to find the mass of each element in the sample

Step 2: Divide the mass of each element by the element's molar mass to find the moles of each element in the sample. Remember to round your answers to the correct number of significant digits.  

Step 3: Divide the moles of each element by the the smallest number of moles of any element to find the mole ratio of elements in the sample.  

Step 4: Multiply the mole ratio by the smallest whole number that changes it into a whole number ratio to find the atom ratio of elements in the sample.

Note that the result of each multiplication must equal a whole number only within measurement uncertainty.  

The measurement uncertainty in this calculation comes from the measurement uncertainty of the mass percents given in the question. The mass percents each have significant digits. That means each mass percent has some measurement uncertainty in the third significant digit, and only the first two significant digits can be considered completely reliable.  

In Step 1 you multiplied each mass percent by something with zero uncertainty (the exactly you assumed your sample weighed), in Step 2 you divided by a measurement with more than significant digits (the molar mass of the elements), and in Step 3 you divided by a measurement with the same number of significant digits (the least number of moles of any element in the compound). None of these steps added to the measurement uncertainty of your calculation.  

Therefore, the measurement uncertainty in the final result of all your calculations is determined by the measurement uncertainty in the original mass percents and will be in the third significant digit. That means the result of each of the final multiplication steps must equal a whole number only to within the first two significant digits.

Answer:

Redox type

Explanation:

The reaction is:

2Cr +  3Fe(NO₃)₂ → 2Fe + 2Cr(NO₃)₃

2 moles of chromium can react to 3 moles of iron (II) nitrate in order to produce 2 moles of iron and 2 moles of chromium nitrate.

If we see oxidation state, we see that chromium changes from 0 to +3

Iron changed the oxidation state from +2 to 0

Remember that elements at ground state has 0, as oxidation state.

Iron is being reduced while chromium is oxidized. Then, the half reactions are:

Fe²⁺  +  2e⁻ ⇄  Fe    (Reduction)

Cr ⇄ Cr³⁺  +  3e⁻    (Oxidation)

When an element is being  reduced, while another is being oxidized, we are in prescence of a redox reaction.
