Explanation:

Answer:

Cutting calories will help you lose weight. But dieting alone can strip away muscle along with body fat. Research suggests that as much as 25 per cent of weight lost by dieters is from muscle. And that's not a good thing.

Explanation:

The maximum no. of electrons in a shell is given by. 2n^2 .

So for

n= 5 , 2× 5× 5 = 50

n=2 , 2×2×2 = 8

For a sub shell the maximum no. of electrons possible is given by 2(2l + 1)

So for n= l= 0

2 [(2×0) +1] = 2

for n=2 l=1

2 [(2×1) + 1] = 6

3d

d sub shell has l= 2 quantum number

Therefore 2[ (2×2) + 1] = 10

2s

s sub shell has l=0 quantum number

2 [(2×0) +1] = 2

5f

f sub energy level has l=3 quantum number

So 2[ (2×3) +1 ] = 14

The azimuthal quantum numbers for the sub shells are as follows

( s ---> 0

Answer:

0.116 moles

Explanation:

To go from grams to moles, you take the given mass (1.39g) and divide it by the molar mass (which is about 12 grams for Carbon). This gives you the moles. I have attached my work below.

Hope this helps! :^)

Answer:3.39

Explanation:

Answer:

molarity 0.1

Explanation:

mass of copper nitrate =2.4

no of moles exist in 120ml= 2.4/187.5=0.0128mole

molarity =.0.0128/.12=0.1m

Explanation:

If you use the SI units for P, n, R and T ( In Pa, mol, JK-1mol-1 and K respectively) you'll end up with a Volume with m3 units. So if you have others in different units first convert them into the units I mentioned above and you will definitely get the answer in m3.

Answer: There are 36 valence electrons.

Explanation:

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the valence electrons of C₄H₈O₂ is 32.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

A valence electron is a negatively charged particle, located in the outermost shell of an atom, that can be transferred to or shared with another atom. To calculate total valence electrons in C₄H₈O₂, we need to add the individual valence electrons of each element.

Valence electrons of C₄H₈O₂= {valence electrons of C×4}+{valence electrons of H×4}+{valence electrons of O×2}

Valence electrons of C₄H₈O₂= {4×4}+{1×4}+{6×2}

Valence electrons of C₄H₈O₂=32

Therefore, the valence electrons of C₄H₈O₂ is 32.

2.Is Exothermic.  An Endothermic Reaction is a chemical reaction that absorbs energy in the form of light or heat. In it, the energy or enthalpy of the reactants is less than that of the products. An Exothermic Reaction is a chemical reaction that gives off energy in the form of light or heat.

3. Reactans.

4. The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.

Given what we know about the mechanisms surrounding the biological movement of substances, we can confirm that when two substances in a secondary active transport move in the same direction, it is called a symport.

A secondary active transport harnesses the electrochemical energy generated by its movement of one substance, to aid the movement of the other. These movements can be of two types, depending on the directions:

An antiport transport will move both substances in opposite directions, meaning one out of the cell and one into the cell. The transport described in the question is that of a symport, given that it moves both substances in the same direction.

Answer:

Sodium has 11 electrons. The first two fill the innermost energy level. The second energy level is also full, holding eight electrons and one electron remaining in the outer energy level. It is the number of outer electrons that give an element its chemical properties.

Explanation:

Sodium has 11 electrons. Therefore electronic configuration of sodium is (2,8,1).

Electrons are the negatively charged particles of an atom. An atom contains a positive proton, a negative electron, and a neutral neutron. Electrons are negatively charged particles that rotate around the atom.

There are around 118 elements in the earth. Sodium is a important element. The atomic number of sodium is 11. The first shell contains 2 electrons, 2nd shell contains 8 electrons and 3rd shell will have 1 electron in sodium.

Sodium is a metal. It will loose that one electron and become cation. It become Na+.

Therefore, Sodium has 11 electrons. Therefore electronic configuration of sodium is (2,8,1).

Answer:

Explanation:

Answer:

93.75

Explanation:

In first half life 750×1/2 will remain

In second one half from that remained at the end of first half life will remain

That is 1/2 × 750×1/2

likewise at the end of 3rd half life 1/2 × 1/2 ×750×1/2 remains

at the end of 4th half life 1/2 × 1/2 × 1/2 ×750×1/2 remains

1/2 × 1/2 × 1/2 ×750×1/2 = 93.75 remains.

You can also use the equation

Remainder = X × 1/2^n .

This saves time

n= no. of half lives

X= initial amount

so in this case 1/2^4 × 750 = 93.75
