What is the mass, in grams, of 0.450 moles of Sb?

Answers

Answer:

54.9 g

Explanation:

0.450 mol x 122g/mol

Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. Therefore, 54.9 g is the mass in grams of 0.450 moles of Sb.

What is mass?

Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.

Average atomic mass = (mass of first isotope× percent abundance of first isotope)+(mass of second isotope× percent abundance of second isotope)

Mass of  Sb= number of moles of  Sb ×Molar mass of  Sb

=0.450 mol x 122g/mol

=54.9 g

Therefore, 54.9 g  is the mass in grams of 0.450 moles of Sb.

Which quantum number describes the orientation of an orbital within a sublevel?

Answers

Explanation:

Each orbital within a particular sublevel is distinguished by its value of ml. This quantum number may be more aptly named the orbital orientation quantum number. In each energy sublevel (designated by l) there are 2l+1 possible independent orientations of the electron cloud.

Answer:

[tex]m_l-magnetic[/tex]

Explanation:

The principal energy level, n, tells us which shell it is in and the total energy of the electron.

The angular momentum (azimuthal), l, tells us which sublevel/subshells the electron is in.

The magnetic, m sub l, tells us the orientation the electron is spinning.

When 38 g of a metal at 92 °C is added to
43 g of water at 22°C, the temperature of the
water rises to 30°C. What is the specific heat
capacity of the metal? Assume no heat was
lost to the surroundings.

Answer in units of
J/g degrees C

Answers

The specific heat  capacity of the metal : 0.610 J/g° C  

Further explanation  

The law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released  

Q abs = Q received  

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

∆T = T(final temp) - T(initial temp)

mass of metal = 38 g

T initial metal = 92 °C

mass of water = 43 g

T final water = 30  °C

T initial water = 22°C

c water = 4.18 J/g° C  

Heat absorbed by water

[tex]\tt Q=m.c.\Delta T\\\\Q=43\times 4.18\times (30-22^oC)\\\\Q=1437.92~J[/tex]

the specific heat  capacity of the metal

Q water = Q metal

[tex]\tt 1437.92=38\times c\times (92-30)\\\\c=0.610~J/g^oC[/tex]

B. decrease and the carbon dioxide level will decrease,
C, increase and the carbon dioxide level will increase.
D. decrease and the carbon dioxide level will stay the same.
E increase and the carbon dioxide level will decrease.

Answers

Answer:

A

Explanation:

Animals take in oxygen and convert it into carbon dioxide therefore the oxygen levels will decrease and the carbon dioxide levels will increase

If an animal is placed into a sealed container for a short time, the oxygen level will:  decrease and the carbon dioxide level will increase.

What happens to oxygen level inside a container:

The oxygen held inside the space is quickly being consumed by the freight or because of rusting inside a space, and that encased spaces must consistently be treated as perilous. And the carbon dioxide levels on the other hand will increase.

It will not take a long time for an animal to survive under these conditions.

Thus. option A is correct.

Answers

Answer:

Answer Below

Explanation:

When you leave an apple on a table outside it will turn brown. This happens because when you cut an apple, you are exposing it's insides to the oxygen in the air. This causes the PPO (polyphenol oxidase) enzyme in the apple's flesh to oxidize the polyphenols, turning them into some other brown colored products. Hence, the color change.

Explanation:

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Three widely used definitions of atomic radius are: Van der Waals radius, ionic radius, and covalent radius

What are chemical and physical changes?

The term “physical change” refers to a change in an object's appearance. When there is a change in the surroundings of the object, such as a rise in temperature or pressure, a physical change takes place.

When candles are burned, the wax melts, but as soon as the temperature drops, the wax hardens and solidifies once more.

Here, chemical changes happen because these changes can not be undone again. When a substance changes their appearance, they always have the same mass.

Thus, the correct options are A. Both are caused by heating, C. Both conserve mass, and D. Both are chemical changes.

348 g of water starting at 4.0°Celsius is heated until his temperature is 37°Celsius. Calculate the amount of heat energy needed to cause this rise in temperature

STEP BY STEP EXPLANATION!!

Answers

Answer:

48.049 kJ or 48049 J

Explanation:

Hello again.

So we know the formula [tex]q = mc\Delta t[/tex]. c is the heat capacity but this time, it is not given. However, water has a very well known heat capacity which is 4.184 J/(g°C). This is in fact the number we refer to a calorie which is the amount of energy you burn that can raise the temperature of 1g of water by 1°C. So, plugging in values, you get the above. But double check if I am wrong.

The amount of heat energy needed to cause this rise in temperature is 48.049 kJ or 48049 J.

What is heat energy?

Heat is the energy that moves from one body to another when temperatures are different. Heat passes from the hotter to the colder body when two bodies with different temperatures are brought together.

A given amount of matter's heat capacity is the amount of energy needed to raise its temperature by one degree Celsius.

The heat energy will be calculated by the formula

Q = m•C•ΔT

Where c is the heat capacity.

The m is the mass

T is the time

Mass is 348 grams

Temperature is 37°C

The change in temperature is 4.0°C to 37°C

The heat capacity of water is 4.184

Q = 348 x 4.184 x -33 = 48049.056.

Therefore, the amount of heat energy needed is 48.049 kJ or 48049 J.

Which pair of symbols represents nuclei with the same number of neutrons?
A. 56 Co and 580
B. 57Co and 58Ni
c. 57Fe and 58 Ni
D. 57Mn and 57Fe

Answers

Answer:

B

Explanation:

Mass number  = number of neutrons + number of protons

Atomic number is the number of protons in the nucleus.  

58Ni   : 58 is the number of neutrons + number of protons

atomic number of Ni is 28.  Thus,  58 -28 = 30 neutrons

57Co ;  57 is the number of neutrons + number of protons

number of Co is 27. Thus, 57 – 27  = 30 neutrons

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,  

alpha α particles ₂He⁴ beta β ₋₁e⁰ particles gamma particles γ positron particles ₁e⁰

Radon-222 emits alpha α particles ₂He⁴  , so the atomic number decreases by 2, mass number decreases by 4
