1. What type of circuit is in the diagram? parallel circuit series circuit

Chemistry
1 answer:
devlian [24]2 years ago
5 0

Answer:

A series circuit is defined as the circuit in which a number of resistances are connected one after the other.. In a series circuit, the flow of current follows a single path.

A parallel circuit is defined as the circuit in which a number of resistances are linked across each other in such a way that one terminal of each resistance is connected to form a junction point while the remaining end is also connected to form another point.

You havent added the diagram so i cant tell you the answer, but i added the definition of each circuit, see if that helps!

Answer:

1.) The total possible combination of alleles for those genes in humans is approximately 70,368,744,177,664. This is trillions of times more combinations than the number of people who have ever lived. This accounts for the fact that nearly everyone, except m0n0zyg0tic twins, is genetically unique.

2.) A hom0zyg0us recessive allele c0mbination contains two recessive alleles and expresses the recessive phen0type. For example, the gene for seed shape in pea plants exists in two forms, one form (or allele) for round seed shape (R) and the other for wrinkled seed shape (r).

4.) If the alleles are heteryg0us recessive, the faulty allele would be recessive and not express itself. Instead, the person would be a carrier. If the alleles are heterozyg0us dominant, the faulty allele would be dominant.

aluminum has a density or 2.7g/cm3. copper has a density of 8.96/cm3. which metal would you choose to build a model airplane?
erik [133]

Answer: Aluminium

Explanation: Aluminium metal has a lower density than copper. So, for the same volume of metal used to build a model airplane, the aluminium plane would be very lightweight while that of copper would be heavy.  The lightweight airplane will fly easily.

The empirical formula of a compound is CH. At 200 degree C, 0.145 g of this compound occupies 97.2 mL at a pressure of 0.74 atm.
Vladimir [108]

Answer:

The molecular formula = C_{6}H_{6}

Explanation:

Given that:

Mass of compound, m = 0.145 g

Temperature = 200 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T = (200 + 273.15) K = 473.15 K

V = 97.2 mL = 0.0972 L

Pressure = 0.74 atm

Considering,  

n=\frac{m}{M}

Using ideal gas equation as:

PV=\frac{m}{M}RT

where,  

P is the pressure

V is the volume

m is the mass of the gas

M is the molar mass of the gas

T is the temperature  

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the values in the above equation as:-

0.74\times 0.0972=\frac{0.145}{M}\times 0.0821\times 473.15

M=78.31\ g/mol

The empirical formula is = CH

Molecular formulas is the actual number of atoms of each element in the compound while empirical formulas is the simplest or reduced ratio of the elements in the compound.

Thus,  

Molecular mass = n × Empirical mass

Where, n is any positive number from 1, 2, 3...

Mass from the Empirical formula = 12 + 1 = 13 g/mol

Molar mass = 78.31 g/mol

So,  

Molecular mass = n × Empirical mass

78.31 = n × 13

⇒ n ≅ 6

The molecular formula = C_{6}H_{6}
