According to the law of multiple proportions, if 12 g of carbon combine with 16 g of oxygen to form co, the number of grams of c
scZoUnD [109]

The amount of carbon combined with oxygen in order to form Carbon Dioxide(CO₂)  is 12 grams

The Law of Multiple proportions is one of the basic laws in chemistry along with the Law of Definite proportion. This law was proposed by John Dalton in 1803. The law states that if two elements react to form one or more compounds then the ratio of masses of both the elements is in the ratio of small whole numbers.

It is known that Carbon can form two different compounds while reacting with Oxygen that is: Carbon Monoxide, Carbon Dioxide. For Carbon Monoxide, 12g of Carbon needs to react with 16g of Oxygen. Whereas, In Carbon Dioxide, 12g of Carbon needs to react with 32g of Oxygen. So the mass of Carbon is equal in both cases is 12g.

                      C(12g)   +   O(16g)   ⇒  CO   (Carbon Monoxide)    

                      C(12g)   +  2O(32g) ⇒  CO₂  (Carbon Dioxide)

Which complex ion can exhibit geometric isomerism? Assume that M is the metal ion, A and B are ligands, and the geometry is octa
Archy [21]

Answer:

[MA4B2]2+

Explanation:

Octahedral species are species that has a coordination number of of six. This means that six ligands are attached to the central metal atom/ion.

For any octahedral specie to exhibit geometrical or cis-trans isomerism, it must have the formula EX2Y4 as in [MA4B2]2+, hence the answer above.

What is the pOH of a 0.00037 M solution of barium hydroxide
ruslelena [56]

Answer: pOH = 3.13

Ba(OH)2 is a very basic substance. The general formula for pOH is - log(OH)

Barium Hydroxide produces 2 moles of OH for every mole of Ba(OH)2 present in the solution.


0.00037 M = 3.7 * 10^-4 Ba(OH)2 will produce 2 *0.00037 M of OH-

OH- = 2* 0.00037 = 0.00074

pOH = - log(0.00074) = 3.13

Which represents the balanced equation for the beta minus emission of phosphorus-32?
Agata [3.3K]

Answer: The correct option is C.

Explanation: Beta minus ( \beta ^- ) decay is the decay in which a neutron is converted into proton and releases beta particle or generally known as electron.

There is an increase in the Atomic number because one protons is being formed.

In the case of beta-minus decay of phosphorous, the P-nucleus gets changed to Sulfur nucleus. The balanced Chemical equation for this process is:

^{32}_{15}\textrm{P}\rightarrow ^{32}_{16}\textrm{S}+^0_{-1}\beta

Hence, the correct option is C.
