Are all the wax rings melting at the same time?

Answer:

the same number of atomic orbitals.

Explanation:

Answer:

All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.

Because baseballs are made out of things that make it heavier then tennis balls, easier to play the sport. that's why they use a bat in baseball.

Answer:

The vertical columns (groups) of the periodic table are arranged such that all its elements have the same number of valence electrons. All elements within a certain group thus share similar properties.

hope this helps

Explanation:

Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.

Answer:

One arrow is positioned in each box according to Hund's Rule which tells us to maximise the number of unpaired electrons in orbitals of the same subshell, and, to give those electrons the same "spin" (parallel spin).

What is the molar concentration of a solution prepared by dissolving 3.05 grams of sodium acetate in enough water to prepare 3.43 x 102 mL of the solution

sodium acetate NaCH3COO has molar mas of

23 + 12 +24 + 1 +32 = 92 g/mol

3.05 g is 3.05 g/ 92 g/mol = 0.0328 moles

it is distributed over 102 mL = 0.102 L

its concentration is 0.0328/ 0.102 =0.296 M Mhttps://brainly.com/question/25586315?answering=true&answeringSource=feedPublic%2FhomePage%2F3#

Answer : E cell standard is the potential difference between the two electrodes under standard conditions. Overall tendency for the redox reaction to occur spontaneously. A large positive E cell means the reaction is more spontaneous, and a negative E cell indicates a non spontaneous reaction.

Explanation:

explain why the pressure in a sealed container of gas decreases when heat is added to the system?

when you add heat to the gas molecules in a sealed container, the molecules move faster and the pressure INCREASES!!!

IT DOES NOT DECREASE

PV =nrT

IF THE O THEVOLUME IS FIXED (REIN A SEALED CONTAINER) AND THE  NUMBER OF MOLES n is FIXED, THEN THE PRESSURE IS DIRECTLY PROPORTIONAL THE TEMPERATURE

NaCl has a cubic unit cell, best thought of as a face-central cubic array of anions with an interpenetrating FCC action lattice or (vice versa). The cell looks the same whether you start with anions or cations on the corners. Each ion is 6 co-ordinates and has a local octahedral geometry.

NaCl lattice exhibit  cubic unit cell.  The face-centered cubic array of anions with an interpenetrating fcc cation lattice are seen in 3D structure. Each ion is 6-coordinate and has a local octahedral geometry.

Sodium chloride is an ionic compound, formed from the sodium metal and chlorine atom. The ionic bond is formed by loss of one electron from sodium metal to the chlorine atom.

The lattice structure of all metals contains a pool of cations in the sea of mobile electrons.  The electrons can be delocalized into the interstices and thus metals conduct electrically and thermally.

In the fcc lattice of NaCl,  sodium atoms are arranged at the corners and Cl atoms are at the center of each cube face of the cell. They are assumed to touch along face diagonals.

Atoms are arranged at the corners of the cube with another atom at the cube center also hence there will 4 atoms one unit cell.

Bond number

The characteristic of reactions that depends on valence electrons is the bond type.

In chemistry, a chemical bond could be;

Ionic

Covalent

The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.

When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

Explanation:

Answer: If two positive charges interact, their forces are directed against each other. The two charges repel each other.

Explanation: The same occurs with two negative charges, because their respective forces also act in opposite directions.) The electric field and resulting forces produced by two electrical charges of the same polarity.

Answer:

specific heat capacity of the unknown is 629.66 J/kg C

Explanation:

As we know that gold is heated to 72.3 degree C and mixed with water at 24.8 degree C

Now the final temperature of the mixture is 26 degree C

here we can say that heat given by the gold = heat absorbed by the water

So we will have

Q_{in} = Q_{out}Q

in

=Q

out

2.62 s (72.3 - 24.8) = 15.6 (4186) (26 - 24.8)2.62s(72.3−24.8)=15.6(4186)(26−24.8)

so we will have

s = 629.66 J/kg Cs=629.66J/kgC

so specific heat capacity of the unknown is 629.66 J/kg C

Answer:

96mg

Explanation:

Since the half-life of Palladium-100 is 4 days and the sample has been reduced after 16 days, that means the sample has undergone four half-lives. To find the intial mass, just work backwards:

As you see, I've worked backwards from the four half-lives. So the initial mass after 16 days is 96 mg.

Answer:

C. South pole on the left end and north pole on the right end

Explanation:

From the figure, we can conclude that the poles of the magnet are on either sides of the magnet

Therefore, options 1 and 2 are excluded

It is a convention that the magnetic field lines move out of the north pole of a magnet and into the south pole of the magnet

From the figure, we can see that the magnetic field lines are moving out from the right end and into the left end

This means that the north pole is at the right end and that the south pole is at the left one

Answer:

41.4 g

Explanation:

2Na(s) + 2H2O (l) ----> 2NaOH ( aq) + H2 (g)

According to the above balnced chemical equation the ratio between moles of H2 gas formed to moles of Na used up is 1:2

Molar mass ( Mass of 1 mol) Of H2 gas is 2 gmol-1

So in 1.8 g of H2 0.9 mol should be present

Therefore no. of moles of Na used should be 2× 0.9 = 1.8 moles

Molar mass of Na= 23 gmol-1

So mass of 1.8 mol of Na = 1.8× 23 g = 41.4g
