Answers

Answer:

Here is every answer for analog and digital (in order)

Analog:

Signal Shape: Smooth and continuousNumerical Values for Signal Measurements: Analog signals represent one continuous variable as the result of another continuous time-based variable. They are capable of outputting continuous information with a theoretically infinite number of possible values.Amount of Data that can be transmitted: analog circuits can conduct only fairly low-speed data communications. The maximum data rate over an analog facility is 33.6K bps when there are analog loops at either end. With 56K bps modems, only one end of the loop can be analog. The other end of the connection has to be digital. Energy requirements: light, sound, temperature, position, and pressurePrivacy and security (ability of the signal to be encoded in a secret code): not encryptedClarity of Signal: noise affects clarity and quality, noise is amplified, amplified noise causes more random information in the signal, signal bandwidth is low

Digital (in order):

Signal shape: stepping, square, and discreteNumerical Values for Signal Measurements: digital communication methods transmit a complete measured value, in other words both a numeric value and a unit of measurement Amount of data that can be transmitted: First of all, it is theoretically possible to transmit digital signals directly. Unfortunately when we use capacitors and inductors (energy storage devices) to match the impedance from the transmitter to the air (low impedance transistor say 5 ohms to 388 ohms (air)) these components introduce a bandwidth limiting match. Since all impulse functions have infinite bandwidth (transmitting a 1 and a zero) the bandwidth of the transceiver must be multi octave in order to have any reasonable efficiency. Systems engineers simplify the problem by introducing direct sequence modulation where a carrier is modulated 0/180 degrees dependent on the data rate.Energy requirements: voltage, accoustic pressure, and magnetization of a magnetic storage mediaPrivacy and security: encryptedClarity of signal: noise is lower in amplitude, electronics can ignore the noise, quality of signal is maintained, signal is high

Calculate the mass of magnesium sulphate that would be obtained from 4g of
magnesium
(Show your working.)

Answers

Answer:

Reaction

Mg+H2SO4 ----》MgSO4+H2

so calculate the moles of magnesium first

moles of magnesium = given mass of mg/molar mass of magnesium

moles = 4/24.30

moles = 0.1646

One mole of magnesium produces one mole of magnesium sulphate

so 0.1646 moles of mg will produce 0.1646 moles of MgSO4

Mass of MgSO4 = 0.1646× 120.366

MgSO4 = 19.81 gm

conclusion the mass of magnesium sulphate that would be obtained from 4g of

magnesium is 19.81 gm!!

If a chemist dilutes 2L of 0.700M solution to 3 L what will be the new concentration (M)

Answers

Answer:

Molarity of our solution= 0.46=0.5

Explanation:

When diluting a solution we can use the formula: 1 1 = 2 2

= M= Molarity of the solution

=V=volumes

On the left side, we'll put what we know/already have and on the right side of the formula we'll put down what we want to dilute it to.

Let's plug in what we already know.

(0.700M)(2L) = (M2)(3L)

Solve for M2 by dividing both sides by 3 so M2 will be by itself.

(0.700M)(2L)/(3L) = M2

M2= 0.46, we can round it up to 0.5

Temperature and precipitation is the major determining factor in soil formation. They define the type of organic material that can be present inside the soils as well as how rapidly weathering will occur.

What is soil?

The bioactive, porous media that has grown in the top layer of the Earth's crust is known as soil. Being a source of water as well as nutrients, a filter for harmful wastes, a site for their breakdown, and a participant inside the cycle of elements such as carbon through the planet's ecosystem, soil constitutes one of the main substrates of life on Earth.

It has changed as a result of weathering processes influenced by geographical, geologic, biological, and climatic factors. A practical understanding of soils including their management has also developed out of need since the development of agriculture with forestry in the eighth millennium BCE. Temperature and precipitation is the major determining factor in soil formation. They define the type of organic material that can be present inside the soils as well as how rapidly weathering will occur.

Therefore, temperature and precipitation is the major determining factor in soil formation.

Fe: 26: [tex]1s^2s^22p^63s^23p^64s^23d^{6}[/tex]

[tex]Fe^{3+}:23:1s^2s^22p^63s^23p^63d^{5}[/tex] : 5 unpaired electrons

Mn: 25: [tex]1s^2s^22p^63s^23p^64s^23d^{5}[/tex]

V: 23: [tex]1s^2s^22p^63s^23p^64s^23d^{3}[/tex]

[tex]V^{3+}:23:1s^2s^22p^63s^23p^63d^{2}[/tex] : 2 unpaired electrons

Ni : 28 : [tex]1s^2s^22p^63s^23p^64s^23d^{8}[/tex]

[tex]Ni^{2+}:23:1s^2s^22p^63s^23p^63d^{8}[/tex]: 2 unpiared electrons

Pb(NO3)2 (aq) + 2 NaI (aq) --> PbI2 (s) + 2 NaNO3 (aq)

Starting with with 50.0 grams of Pb(NO3)2 and 30.0 grams of NaI:
A. What is the limiting reagent?
B. How many grams of the excess reactant remains?
C. How many grams of each product is formed?
D. If 12 grams of NaNO3 actually formed in the reaction, what is the percent yield of this reaction?

Answers

Answer:

Explanation:

Moles of Pb(NO3)2 =  mass/molecular mass

= 50.0 grams/(207.20*1 + 14.01*2 + 16*6)

= 50.0 grams/331.22

= 0.15 moles

Moles of NaI

= 30/(22.99+126.9)

= 30/149.89

= 0.2 Moles

A. NaI is less 2x Pb(NO3)2 so NaI is the limiting reagent.

B. The ratio is 1 to 2 so there is 0.15 - 0.2/2 = 0.05 mole

or 16.78 grams of Pb(NO3)2 left.

C. As NaI is limiting, only 0.2 Moles of NaNO3 is formed.

Mass =  Moles * Molecular Mass

Molecular Mass of NaNO3 can be calculated as:  

Na - 22.99

N - 14.01

O - 3(16) = 48

23+14+48 = 85gram / mole

Thus, Mass =  0.2*85  = 17 gram of NaNO3

Mass is conserved in a chemical reaction.

Mass of PbI2 can be calculated as:

50+30-16.78-17

= 46.3 gram of PbI2

Mass =  

12.75

Thus, 12.75g of Sodium Nitrate can be formed

Answer:

Explanation:

Pb(NO3)2 (aq) + 2 NaI (aq) --> PbI2 (s) + 2 NaNO3 (aq)

MM for each compound -

Pb(NO3): 207 + 14x2 + 16x3x2 = 331

PI2: 207 + 127x2 = 461

NaI: 23 + 127 = 150

NaNO3: 23 + 14 + 16x3 = 85

Moles of Pb(NO3)2 = 50/331 = 0.15

Moles of NaI = 30/150 = 0.2

Ratio of moles is 1:2

So NaI is limiting

Limited to 0.2/2 = 0.1 mole of Pb(NO3)2

Excess = 0.15 - 0.1 = 0.05 mole

Mass remains = 0.05x331 = 16.55 grams

Moles of NaNO3 formed = Moles of NaI reacted = 0.2

Mass = 0.2x85 = 17 grams

Moles of PbI2 formed = Moles of Pb(NO3)2 reacted = 0.1

Mass = 0.1x461 = 46.1 grams

If 12 grams of NaNO3 actually formed in the reaction,

percent yield = 12/17x100% = 70.6%
