    The  partial     pressure  of  the  oxygen  gas  in  the  mixture  is  calculated  is  calculated  as  follows


total  pressure  of oxygen  +    nitrogen  
the  partial pressure   of  oxygen    percentage  of  0xygen  /  total  percentage x   total  pressure
  =  10/100x800=  80  mmHg

Answer:

The partial pressure of the oxygen gas in the mixture is 80 mmHg.

Explanation:

Total pressure of the gas mixture ,p = 800 mmHg

Percentage of oxygen gas = 10% = 0.10 =\chi_{O_2}

Percentage of nitrogen gas = 90% = 0.90=\chi_{N_2}

Partial pressure an individual gas in a mixture is given by Dalton's law of partial pressure:

p_{O_2}=p\times \chi_{O_2}=800 Hg \times 0.10 =80 mmHg

p_{N_2}=p\times \chi_{O_2}=800 Hg \times 0.90 =720 mmHg

The partial pressure of the oxygen gas in the mixture is 80 mmHg.

Based on the activity series, which one of the reactions below will occur (Spontaneous)? A. Mn (s) + NiCl2 (aq) → MnCl2 (aq) + N
kap26 [50]

Answer:

Mn (s) + NiCl2 (aq) → MnCl2 (aq) + Ni

Explanation:

The order of displacement of metals from aqueous solution by another metal is defined by the activity series of metals.

The activity series arranges metals in order of reactivity and increasing electrode potentials. The less negative the electrode potential of a metal is, the less reactive it is and the lower it is found in the activity series.

Nickel has a less negative electrode potential than manganese hence it is displaced from an aqueous solution of its salt by manganese spontaneously.

The crack shown in the lithosphere was created by the movement of two or more tectonic plates. What is this crack called
nikitadnepr [17]

Answer:

The lithosphere is made up of pieces of tectonic plates. These plates are constantly changing and move towards the mantle. Non-stop movement of tectonic plates causes stress on the earth's outermost layer i.e,the crust. When these stresses extends it leads to cause cracks called faults.

What is the purpose of adding 0. 1% agar to the trypticase nitrate broth when conducting the nitrate reduction test?.
PilotLPTM [1.2K]

Agar is used to assist establish an anaerobic environment that promotes nitrate reduction.

Nitrate Reduction test:

  • The nitrate in the broth is converted to nitrite by organisms that can produce the nitrate reductase enzyme, which can then be further converted to nitric oxide, nitrous oxide, or nitrogen.
  • Anaerobic respiration and denitrification are two processes that can convert nitrate to a variety of compounds.
  • While denitrification only reduces nitrate to molecular nitrogen, anaerobic respiration employs nitrate as the bacterium's final electron acceptor, reducing it to a range of chemicals.
  • The nitrate reduction test is based on the detection of nitrite and its capacity to produce a red precipitate (prontosil), which is a water-soluble azo dye, when it combines with sulfanilic acid to create a complex (nitrite-sulfanilic acid).
