Answer:

3d

Explanation:

Transition metal are elements having partially filled d sub shell. In these metals last electron is filled in d sub shell.

General electronic configuration of transition metal: (n-1)^{1-10}ns^{1-2}

Where, n = outermost shell.

Period 4 means, last shell no. is 4.

For transition metals of period 4,

General electronic configuration: 3d^{1-10}4s^{1-2}

for example, Fe belong to periods 4.

Electronic configuration of Fe: [Ar]3d^64s^2

So, filling of 3d orbital is represented by transition metal of 4.

Transition metals are the metal located in the center block of the periodic table. Also, this block represents the D sublevel.

So, the answer is 3d.

Also, keep in mind that the D block starts "one period late". this means that if you are in period 4, the 3d orbital starts. if you are in period 5, that where 4d starts.

A(g) + 2B(g) → C(g) + D(g)
WITCHER [35]

Answer:

0.169

Explanation:

Let's consider the following reaction.

A(g) + 2B(g) ⇄ C(g) + D(g)

We can find the pressures at equilibrium using an ICE chart.

       A(g) + 2 B(g) ⇄ C(g) + D(g)

I       1.00     1.00        0        0

C       -x        -2x        +x       +x

E    1.00-x  1.00-2x     x         x

The pressure at equilibrium of C is 0.211 atm, so x = 0.211.

The pressures at equilibrium are:

pA = 1.00-x = 1.00-0.211 = 0.789 atm

pB = 1.00-2x = 1.00-2(0.211) = 0.578 atm

pC = x = 0.211 atm

pD = x = 0.211 atm

The pressure equilibrium constant (Kp) is:

Kp = pC × pD / pA × pB²

Kp = 0.211 × 0.211 / 0.789 × 0.578²

Kp = 0.169

A pair of students determining the molarity of their unknown HCl solution calculates the concentration to be 0.0961 M on their f
Varvara68 [4.7K]

Answer:

Yes.

Explanation:

It should be noted that the meaning of molarity is the ratio of moles of solute per liter of solution.

It should be understood that when determining or finding the molarity of an unknown compound ,the process should be performed or carried out at least 3 times. This is done to remove any form of doubt.

The first calculated value for the concentration of the compound will be regarded as rough value, while the second and the third will be regarded as the first and second values respectively.

In this case, the third value for the concentration of HCl will be calculated to for confirmation of other value, that is to be finally sure of its concentration.

Do you think that the human being is the center of the universe?
Andrej [43]
I think that the sun is the center of the universe, not a human being. Everything revolves around the sun, not someone. U know when to sleep, when the time is, and when to wake up based on the sun. All the planets revolve around it. This is why I think the sun is the center of the universe, not a human being.
