You want to measure the volume of a gold bracelet. For this purpose, a specimen with 20 mL of water is available; when inserting the bracelet, the water level rises to 25 mL. If the density of gold is 19300 Kg/m3. What will be the mass of the bracelet?

Answers

Answer:

volume of bracelet is 5cm3

mass is 0.0965Kg

Explanation:

1ml = 1cm3

1m3 = 1000000cm3

0.000005m3

Mass = volume*density

19300 Kg/m3 * 0.000005m3 = 0.0965Kg

what does the phrase sea of electrons describe?? please help

Answers

Answer: Metallic Bonding.In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.

what is the dilution factor if you add a 0.1ml aliquot of a specimen to 9.9 dilutent

Answers

The dilution factor : 100

Further explanation

The dilution factor(DF) : ratio of concentration of stock solution and diluted solution or ratio of the volume of final solution to the initial volume from stock solution

From equation of dilution :

M₁V₁=M₂V₂

[tex]\tt DF=\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}[/tex]

Volume of aliquot = 0.1 ml

Volume of diluent = 9.9 ml

So final volume :

[tex]\tt V_f(final~volume)=volume~aliquot+volume~diluent\\\\V_f=0.1+9.9=10~ml[/tex]

The dilution factor (DF) :

[tex]\tt D_f=\dfrac{V_f}{V_i}\\\\D_f=\dfrac{10}{0.1}=100[/tex]

Answers

Answer:

Temperature

Explanation:

Because Temperature is a measure of the average kinetic energy of all the molecules in a gas. As the temperature and, therefore, kinetic energy, of a gas changes, the RMS speed of the gas molecules also changes. The RMS speed of the molecules is the square root of the average of each individual velocity squared.

Your car has 1.95 gallons of gasoline (octane, d = 0.6916 g/mL), which reacts with oxygen
according to the balanced reaction below. Your car uses the energy produced by this reaction
at a rate of 115 kJ per second while traveling at a speed of 65 miles per hour. Calculate the
distance (in miles) the car can travel using this amount of octane.
2 C8H18(g) + 25 O2(g) -----> 16 CO2(g) + 18 H2O(g) ΔHrxn = -10,900 kJ

Answers

Answer:

38.3 miles

Explanation:

First, we convert 1.95 gallons to mililiters:

1.95 gallons * [tex]\frac{3.785 L}{1gallon}*\frac{1000mL}{1 L}[/tex]= 7380.75 mL

Then we calculate how many grams of octane are available for the reaction, using its density:

0.6916 g/mL * 7380.75 mL = 5104.53 g C₈H₁₈

Now we convert octane grams into octane moles, using its molar mass:

5104.53 g C₈H₁₈ ÷ 114 g/mol = 44.78 mol C₈H₁₈

Then we calculate how many kJ are produced from the combustion of  44.78 mol C₈H₁₈, if 2 moles produce 10900 kJ:

44.78 mol * 10900 kJ / 2 mol = 244032 kJ

We calculate how many seconds is the car available to keep going, if it spends 115 kJ per second:

244032 kJ * 1 s / 115 kJ = 2122.02 s

We convert seconds to hours:

2122.02 / 3600 = 0.59 hours

Finally we calculate the distance:

65 mi/hour * 0.59 hour = 38.3 mi

Answers

The atomic number of this atom : 8

Further explanation

Given

Atomic model (attached)

Required

The atomic number

Solution

To determine the atomic number of an element, we can look at the number of electrons or the number of protons, because

atomic number = number of protons = number of electrons in neutral atoms

While the mass number is the number of neutrons + the number of protons located in the atomic nucleus

The charge of each of these atomic sub particles:

electron: charge -1proton: charge +1neutron: not charged / 0

If we look at this atomic model, there are 8 electrons in the shell, consisting of 2 electrons in the first shell and 6 electrons in the second shell (which can also be called valence electrons)

Whereas in the atomic nucleus there are 8 protons and 10 neutrons

Answer:8

Explanation:

I am a nonmetal.I am in the Oxygen family and in row 3.I have 6 valence electrons.I am yellow and have a stinky smell.Who am i

Answers

Answer:

sulfur

Explanation:

In oxygen family sulfur has yellow color and also having stinky smell. Thus given statements are about sulfur.

It is present in oxygen family.

It has six valance electrons.

Its atomic number is 16.

Its atomic weight is 32 amu.

The electronic configuration of sulfur is given below,

S₁₆ = 1s² 2s² 2p⁶ 3s² 3p⁴

We can see the valance shell is third shell and it have six electrons thus sulfur have six valance electrons. (3s² 3p⁴ )

Sulfur is used in vulcanisation process.

It is used in bleach and also as a preservative for many food.

it is used to making gun powder.
