The following two structures are Isomers.

Isomers are compounds that contain exactly the same number of atoms, i.e., they have exactly the same empirical formula, but differ from each other by the way in which the atoms are arranged. Examples of isomers with the formula C8H10 are ethyl benzene, m-xylene, p-xylene, and o-xylene.

What are the 3 types of isomers?

There are three types of structural isomers: chain isomers, functional group isomers, and positional isomers.

Isomers are molecules with the same chemical formula but have different structures. Isomers differ in how their bonds are positioned to surrounding atoms.

The question is: WHAT DATA OF THE ELECTRONIC CONFIGURATION ALLOWS YOU TO LOCATE THE CHEMICAL ELEMENTS IN THE PERIODIC TABLE?

Explanation:

Elements which have same number of valence electrons tend to show similar chemical properties due to which they are placed in the same group.

Hence, electronic configuration of an element tells us the number of valence electrons present in an element. As a result, it becomes easy to locate the element in its respective group.

Only β+ decay

Explanation:

In positron emission, a proton is converted into a neutron and a positron. An anti neutrino is a particle that serves the purpose of balancing the spins.

During positron emission, the mass number to the daughter nucleus is the same as that of the parent nucleus but the atomic number of the daughter nucleus is less than that of the parent nucleus by one unit.

Positron emission increases the neutron/proton ratio.

Explanation:

Given :

Amount of solute - sucrose (C12H22O11) = 41 g

Amount of solvent -soda  = 355-mL

Molarity of the solution with respect to sucrose= ?

Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.

Formula to find the molarity of solution :

               Molarity =  

Amount of solvent is given in mL, let’s convert to L :

               1 L = 1000 mL

Therefore, 355 mL in L will be :

               = 0.355 L

We have the amount of solute in g, let’s calculate the number of moles first :

       Number of moles (n) =  

Molar mass of C12H22O11 = 342.29 g/mol.

Therefore, n =  

               = 0.119 moles.

Answer:

the solution becomes less concentrated... meaning there is a decrease in acidity ...hence the pH slightly increases as lesser ph

means more acidity

Answer: increasing the number of collisions between reactants

Explanation:

A reaction is possible due to collisions between the reactants to create products. If we increase the concentration of reactants then that means that we are increasing the molecules of the reactants which would give them more chances to collide and make products.

For instance, using a non-chemistry example, if there are few cars in a large city, the accidents there will be less because the cars will have such space that they wouldn't collide with each other. If the number of cars in the city is increased however, there is now less space and more chances for cars to collide.

Steel is a metal. Metals atoms are able to roll over each other into new positions without breaking the metallic bond. So, steel doesn't break but changes its shape.

Answer:

Explanation:

The rather high specific activity of intracellular sucrase towards sucrose is known to be optimal at pH 6.0 and at a temperature of about 30°C. And thus, we can say that the optimum pH for sucrase activity is exactly at 6. Also, it's behaviour is said to be decreasing with increasing acidic and increasing alkallinic values.

Answer:

Matter or energy can change from one form to the other

Explanation:

The law of conservation of energy states that energy can neither be created nor destroyed but can only be transformed i.e. changed from one form to another. For example, mechanical energy can be changed to electrical energy.

Likewise, the law of conservation of mass/matter states that matter can not be destroyed or created but can change via physical or chemical means to conserve it. For example, matter can change from liquid state to gaseous state.

From the above two laws, it can be said that "matter or energy can change from one form to the other".

Explanation:

Physicists main field of study is physics. This includes everything from force, matter, energy, and even time among other things. Therefore, from the questions provided the one that would most likely be studied by a physicist would be How can the forces on a space probe be controlled so it will land on Mars? This is because this question deals with forces acting on an object, regardless of what the object is Force is a huge part of physics and therefore studied by Physicists.

Because of their complementary nature, the oxidation and reduction processes together are referred to as redox reactions. The reactant that brings about the oxidation is called the oxidizing agent, and that reagent is itself reduced by the reducing agent. Examples are, mercury(II) oxide, oxygen, and the copper(II) ion are oxidizing agents, and carbon, hydrazine, and zinc are the reducing agents.
