describe how changing the particles changed the atom

Answers

Answer 1
bonds between atoms break and new ones form and energy is either given out or taken in
Answer 2

Changing the particles changes the atoms by converting it to a new substance through bond change.

During a chemical reaction changes occurs in the atoms of an element due to the formation or breaking of bonds.

There is either loss or gain or sharing of atoms between two elements reacting together.

Bonds between atoms break and new ones form and energy is either given out or taken in.

This type of reaction leads to the formation of new substances made up of a new combination of atoms and a different configuration of electrons.

Therefore, because various changes occurs during a chemical reaction, changing the particles changes the atoms by converting it to a new substance through bond change.

Answers

Answer:

diamonds

Explanation:

Diamond does not conduct electricity.  

• A form of carbon in which each of the atom of carbon is joined to four other atoms of carbon, giving rise to a giant covalent composition is a diamond.  

• Due to this, diamond is very robust and exhibits high melting point. Thus, is used to cut tools.  

Diamond does not conduct electricity, due to the absence of delocalized electrons in the structure.  

Thus, diamond does not conduct electricity. Option d is correct.

Answers

Answer:

200 cm^3

Explanation:

V = M/D

V = 120g / (0.6g/cm^3)

V = 200 cm^3

In this case, the volume is 200 cm^3.

What is density?

Density is defined as the mass of a material substance per unit volume. The equation for density is d = M/V, where d stands for density, M for mass, and V for volume. Grams per cubic centimetre are a typical unit of density measurement.

For instance, the density of Earth is 5.51 grammes per cubic centimetre, but the density of water is 1 gramme per cubic centimetre. Kg/m3 is another way to measure density (in metre-kilogram-second or SI units). For instance, the air has a density of 1.2 kilogrammes per cubic metre.

Textbooks and manuals provide lists of the densities of common solids, liquids, and gases. The mass of a body may be calculated from its volume using density, and vice versa. The mass is equal to the volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d).

You may calculate a body's weight by multiplying its mass by the acceleration of gravity, which is typical of more practical significance than its mass. Additionally, there exist tables that indicate the weight of various substances per unit volume; this amount is sometimes referred to as specific weight, weight density, or unit weight.

Instead of referring to the density of a single particle, the term "particle density" refers to the number of particles per unit volume and is typically written as n.

Therefore, here the volume is 200 cm^3.

An Olympic swimmer can swim a distance of 360m in 8.5 minutes. What is her speed?

Answers

speed= distance / time
s= 360m / 510 s
s= 0,7 m/s

Answer:

42.3529412 m/min or 0.705882353 m/s

Explanation:

We can calculate speed using the following formula.

[tex]s=\frac{d}{t}[/tex]

where [tex]d[/tex] is distance and [tex]t[/tex] is time.

The Olympic swimmer can swim 360 meters in 8.5 minutes. Therefore,

[tex]d= 360 \ m \\t= 8.5 \ min[/tex]

Substitute the values into the formula.

[tex]s=\frac{360 \ m}{ 8.5 \ min}[/tex]

Divide.

[tex]s= 42.3529412 \ m / min[/tex]

Her speed is 42.3529412 meters per minute.

If we want to find her speed in meters per second, convert the minutes to second.

1 minute is equal to 60 seconds, so we can multiply 8.5 by 60.

[tex]8.5 *60=510[/tex]

The swimmer can swim 360 meters in 510 seconds.

[tex]s=\frac{d}{t}[/tex]

[tex]d= 360 \ m \\t= 510 \ s[/tex]

[tex]s=\frac{360 \ m}{510 \ s}[/tex]

[tex]s=0.705882353 \ m/s[/tex]

Her speed is also 0.705882353 meters per second.

reaction:

If 6.35 grams of sodium carbonate, Na2CO3, were recovered, what percentage (by mass) of the sample was
sodium hydrogen carbonate, NaHCO3?
I

Answers

Answer:

67.1%

Explanation:

Based on the chemical equation, if we determine the moles of sodium carbonate, we can find the moles of NaHCO₃ that reacted and its mass, thus:

Moles Na₂CO₃ - 105.99g/mol-:

6.35g * (1mol / 105.99g) = 0.0599 moles of Na₂CO₃ are produced.

As 1 mole of sodium carbonate is produced when 2 moles of NaHCO₃ reacted, moles of NaHCO₃ that reacted are:

0.0599 moles of Na₂CO₃ * (2 moles NaHCO₃ / 1 mole Na₂CO₃) = 0.1198 moles of NaHCO₃

And the mass of NaHCO₃ in the sample (Molar mass: 84g/mol):

0.1198 moles of NaHCO₃ * (84g / mol) = 10.06g of NaHCO₃ were in the original sample.

And percent of NaHCO₃ in the sample is:

10.06g NaHCO₃ / 15g Sample * 100 =

B. They both involve ionization of some atoms so bonding can occur.
C. They both have delocalized electrons that move from atom to atom.
D. They both allow electrons to move from lower energy levels to higher energy levels.

Answers

Answer:

D

Explanation:

Correct On EDU

Crystal lattice of metals are highly ordered in which the ions and electrons are arranged in a stoichiometric proportion. But,electrons can excite to higher energy levels as they fo in atomic state. Thus , option D is correct.

What is crystal lattice?

Crystal are highly ordered structures of solids and is anisotropic in nature with a perfect geometry and crystal lattice units. There will be free electrons present in the interstices spaces and which can be delocalized throughout the lattice results in conduction.

Electrons can acquire energy to excite to the higher energy levels from the lower energy level in a crystal lattice. Electrons are revolving around the nucleus of an atom through definite circular paths of fixed energy.

Electrons in an atom tends to excite to higher energy levels and then will return to the lower energy level by emission of energy in the form of light or heat. This process make the element coloured and conducting as in the case of crystal bands in metals.

Hence, both atoms and metal lattice allow electrons to move from lower energy levels to higher energy levels and option D is correct.

If you have a 10 gram sample of uranium-235 how much would still be uranium-235 after 1407.6 million years?​

Answers

Answer:

2.48 g

Explanation:

From the question given above, the following data were obtained:

Original amount (N₀) = 10 g

Time (t) = 1407.6 million years

Amount remaining (N) =?

Next, we shall determine the rate of decay (K) of uranium-235. This can be obtained as follow:

NOTE: Uranium-235 has a half life of 700 million years.

Decay constant (K) =?

Half life (t½) = 700 million years

K = 0.693/t½

K = 0.693/700

K = 9.9×10¯⁴ / year

Therefore, Uranium-235 decay at a rate of 9.9×10¯⁴ / year.

Finally, we shall determine the amount of Uranium-235 remaining after 1407.6 million years as follow:

Original amount (N₀) = 10 g

Time (t) = 1407.6 million years

Decay constant (K) = 9.9×10¯⁴ / year

Amount remaining (N) =?

Log (N₀/N) = kt /2.3

Log (10/N) = (9.9×10¯⁴ × 1407.6) /2.3

Log (10/N) = 0.60588

10/N = antilog (0.60588)

10/N = 4.04

Cross multiply

10 = 4.04 × N

Divide both side by 4.04

N = 10/4.04

N = 2.48 g

Therefore, 2.48 g of uranium-235 is remaining after 1407.6 million years.

If you have a 10 gram sample of uranium-235 there would still be uranium-235 after 1407.6 million years - 2.5 grams.

The half-life of U-235 is the time it takes for half the U to decay. We know that U-235 has 703.8 million years as its half-life which means it takes 703.8 million years to half of its initial amount.

After one half-life, half (50 %) of the original amount will remain. After a second half-life, half of that amount (25 %) will remain, and so on.    

We can construct a table as follows:    

No. of                              Fraction        Amount    

half-lives    t/(yr × 10⁶)     remaining    remaining/g    

   1                703.8              ½              10/2 = 5  

   2              1407.6              ¼              10/4 =  2.50    

Thus, the correct answer is - 2.5 grams.
