In 1735 Carlous Linneaus a Botanist said that there needs to be a way to classify organisms and living things. He decided that he'll sort organisms into seven major taxa, or groupings. He called the highest taxa kingdom and the lowest taxa species. This is known as the first idea in the process of Linnaean Taxonomy.

Then in 1990 Carl Wossen a microbiologist and biophysicist added to this idea saying that he Linnaean taxonomy works well, but it could be better. Thta there could be a better way into classifying and grouping kingdoms. He then created 3 domains: Bacteria, Archaea, and Eukarya, aka, regular bacteria, extreme bacteria, and everything else.

This furthermore is the method we use in classifying living things.

The answer is: B, Domain.

Answer:

The answer is " $\bold{4.97 \times 10^{-2}}$ "

Explanation:

Please find the complete question in the attached file.

Equation:

$2SO_2+O_2 \leftrightharpoons 2SO_3$

at $t=0 3.3 \ \ \ \ \ \ \ \ \ \ 0.79$

at equilibrium $3.3-p \ \ \ \ \ \ \ \ \ \ 0.79 - \frac{P}{2} \ \ \ \ \ \ \ \ \ \ \ \ P$

$p= 0.47 \ \ atm\\\\SO_2=3.3-0.47 = 2.83 \ \ atm\\\\O_2= 0.74 -\frac{0.47}{2}=0.74-0.235=0.555 \ atm\\\\K_P=\frac{[PSO_3]^2}{[PSO_2]^2[PO_2]}\\\\$

$=\frac{0.47^2}{2.83^2\times 0.555}\\\\=4.97 \times 10^{-2}$

EastWind [94]

Here, we should use combined gas law which can be derived from combined gas law, “PV=nRT”. Rearranging, we can get PV/T=nR. Then we can set the two states in the problem together to get

P1V1/T1 = P2V2/T2

Then just plug in and solve algebraically.

Hope this helps

Answer : The ionic equation will be:

$CH_3CH(OH)COO^-(aq)+H^+(aq)+Na^+(aq)+HCO_3^-(aq)\rightarrow CH_3CH(OH)COO^-(aq)+Na^+(aq)+H_2O(l)+CO_2(g)$

Explanation :

Neutralization reaction : It is a type of chemical reaction in which an acid react with a base to give salt and water as a product that means it reacts to give a neutral solution.

When baking soda (sodium hydrogen carbonate) base react with lactic acid then it react to gives sodium lactate, carbon dioxide and water as a product.

The balanced chemical reaction will be:

$CH_3CH(OH)COOH(aq)+NaHCO_3(aq)\rightarrow CH_3CH(OH)COONa(aq)+H_2O(l)+CO_2(g)$

The ionic equation will be:

$CH_3CH(OH)COO^-(aq)+H^+(aq)+Na^+(aq)+HCO_3^-(aq)\rightarrow CH_3CH(OH)COO^-(aq)+Na^+(aq)+H_2O(l)+CO_2(g)$
