Answer:

The volume of the 84 grams of bromine gas at STP is 11.77 L.

Explanation:

Mass of bromine gas = 84 g

Moles of bromine gas = \frac{84 g}{160 g/mol}=0.525 mol

where,

P = Pressure of gas = 1 atm (at STP)

V = Volume of gas = ?

n = number of moles of gas = 0.0525 mol

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of gas = 273.15 K  (at STP)

Putting values in above equation, we get:

V=\frac{nRT}{P}

V=\frac{0.525 mol\times 0.0821 atm L/mol K\times 273.15 K}{1 atm}

V = 11.77 L

The volume of the 84 grams of bromine gas at STP is 11.77 L.

Consider the following genotype Yy Ss Hh
Ilya [14]

From: Yy Ss Hh 8 different gametes can be formed

  • 5 Eye Color Genes = 243 genotypes
  • 10 Eye Color Genes= 59049 genotypes
  • 20 Eye Color Genes= 3,486,784,401 genotypes

This is further explained below.

<h3>What is a gamete?</h3>

Generally, Gametes are the cells of an organism that are responsible for reproduction. In certain contexts, they are also referred to as egg cells and sperm cells.

The popular word for female gametes is ova, whereas the common name for male gametes is sperm. Ovum and egg cells are other frequent names for female gametes.

Gametes are instances of haploid cells since they only contain a single copy of each chromosome. Haploid cells are described as having only one copy of each chromosome.

In conclusion, For 5 Eye Color Genes

3^n is implored hence

3^5=243 genotypes

Repeating said pattern e have

  • 10 Eye Color Genes= 59049 genotypes
  • 20 Eye Color Genes= 3,486,784,401 genotypes

Ni-cad (nickel–cadmium) batteries have a slightly lower cell potential than the common alkaline value of 1.5 v normally used in
Lorico [155]
The half-reaction are:

Cd ---> Cd(OH)₂
The oxidation number of Cd changed from 0 to +2. So, the number of mol electron transferred here is 2.

NiO(OH) --> Ni(OH)₂
The oxidation number of Cd changed from +3 to +2. So, the number of mol electron transferred here is 1.

Now, the greatest common factor would be 2. So, we use n=2 for the formula for ΔG°. F is Faraday's constant equal to 96,485 J/mol e.

ΔG° = nFE° = (2)(96,485)(1.5) =<em> 289,455 J</em>

29.5 g of mercury is heated from 32°C to 161°C, and absorbs 499.2 joules of heat in the process. Calculate the specific heat cap
Finger [1]

Answer:

c = 0.13 j/ g.°C

Explanation:

Given data:

Mass of mercury = 29.5 g

Initial temperature = 32°C

Final temperature = 161°C

Heat absorbed = 499.2 j

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Q = m.c. ΔT

ΔT  = T2 - T1

ΔT  = 161°C - 32°C

ΔT  = 129 °C

Q = m.c. ΔT

c = Q / m. ΔT

c = 499.2 j / 29.5 g. 129 °C

c =  499.2 j / 3805.5 g. °C

c = 0.13 j/ g.°C

Why Is Any Chemical Reaction always Balanced? Give reasons and Explain the Easiest way to solve the Balancing Problems in Chemic
erastova [34]

Answer:

The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.
