A) 5
B) 6
C) 7
D) 8

Answer:

Does it have a picture?

Explanation:

The potential difference between the top and bottom of a D cell battery is derived by the use of a voltmeter between the +ve and -ve poles.

The potential difference is simply defined as two points that reflect the energy released in transferring a unit quantity of electricity from one spot to the other.

In conclusion,  Potential difference is also known as the voltage across two points in a circuit.

Answer:

Warming the batter and frying the eggs.

Explanation:

This is a chemical change as the products have very different property as compared to reactant not only physically but also chemically. Therefore, the reaction that is associated with cooking is combustion reaction.

Chemical change is a reaction in which breaking and forming of new bonds take place. One molecule completely converted to totally different molecule. The number of atoms remains same

One famous example of chemical change is the rusting of iron. The color, odor and arrangements of atoms in products are very much different from reactant. Chemical change are mostly irreversible in nature.  

Cooking is a chemical change not a physical change. During cooking the reaction that is associated is combustion reaction as the by product is carbon dioxide and water.

Therefore,  the reaction that is associated with cooking is combustion reaction.

Explanation:

Radium (atomic number 88) has similar properties to barium and is also in the Group 2 category. However, radium is a radioactive element and is generally under the category of radioisotopes in addition to being an alkaline earth metal, because it is not a stable element.

Answer:

Mass = 0.35 g

Explanation:

Given data:

Mass of sodium = 8.0 g

Mass of hydrogen produced = ?

Solution:

Chemical equation:

2Na + 2H₂O     →    2NaOH + H₂

Number of moles of sodium:

Number of moles = mass/molar mass

Number of moles = 8.0 g/ 23 g/mol

Number of moles = 0.35 mol

now we will compare the moles of sodium and hydrogen

             Na           :           H₂

             2             :            1

           0.35          :      1/2×0.35 = 0.175 mol

Mass of hydrogen:

Mass = number of moles × molar mass

Mass = 0.175 mol × 2 g/mol

Mass = 0.35 g

ΔG =   18KJ/mol

Explanation:

Given data:

ΔS = 0.09 Kj/mol.K

ΔH = 27 KJ/mol

Temperature  = 100 K

ΔG = ?

Solution:

Formula:

ΔG = ΔH - TΔS

ΔH = enthalpy

ΔS = entropy

by putting values,

ΔG =  27 KJ/mol - 100K(0.09 Kj/mol.K)

ΔG =  27 KJ/mol - 9 KJ/mol

ΔG =   18KJ/mol

Explanation:

Answer:

37,818.67 m3

Explanation:

The pressure a gas will exert on a container is inversely proportional to the volume of the gas. According to Boyle's law, at a constant temperature, the pressure of a gas is inversely proportional to its volume. The law can be mathematically represented thus:

   P1V1 = P2V2

In this case, P1 = 101.3 kPa, V1 = 28,000 m3, P2 = 75 kPa, V2 = ?

V2 = P1V1/P2

         =    101.3 x 28,000/75

                = 37,818.67 m3

Hence, the new volume of the air inside the cabin after pressurizing would be 37,818.67 m3.

[tex]\boxed {\boxed {\sf C. \ More \ protons \ are \ present \ in \ the \ atomic \ nucleus}}[/tex]

Explanation:

First, let's define atomic number.

    ⇒ The number of protons in an atom.

    ⇒ This number determines the identity and properties of the atom

So, atomic number relates to protons. There is an increase in atomic number, so there must be more protons in the atom. We can eliminate choices A and B, because they pertain to electrons.

We are left with choices C and D. The difference between them is the location of the protons.

Protons are part of the nucleus of the atom: the dense, central region of the atom comprised of nucleons: protons and neutrons.

Electrons, not protons, orbit the nucleus, so  D is not correct.

We are left with choice C: more protons are present in the atomic nucleus

Answer:

protons: 36

neutrons: 48

electrons: 36
