How many d electrons does I (atomic number
53) possess?
1. 10
2. 5
3. 8
4. 0
5. 20
6. 53
7. 16

Answers

Answer:

6. 53 is the answer. Hope this helps:)

The number of d electrons that an atom of atomic number 53 possess are 20. Thus, the correct option for this question is 5.

What is an Atomic number?

An atomic number may be defined as the number of protons in the nucleus of an atom that significantly represents the characteristic of a chemical element and determines its specific place in the modern periodic table.

According to the modern periodic table, an element that has an atomic number of 53 is known as Iodine. Its electronic configuration is [tex]1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^1^0, 4p^6, 5s^2, 4d^1^0, 5p^5[/tex]. Thus, according to this electronic configuration, the total number of d electrons are [tex]3d^1^0 and 4d^1^0[/tex].

Therefore, the number of d electrons that an atom of atomic number 53 possess are 20. Thus, the correct option for this question is 5.

What physical property of the metal rods was being tested during step 4 of the procudure?

4. Measure and record how long it takes heat from the hot plate set on "high" to melt the wax ball.

A.
magnetism
B.
thermal conductivity
C.
electrical conductivity
D.
density

Answers

Answer:

B.  thermal conductivity

Explanation:

They physical property being tested during the fourth step is the thermal conductivity of the materials.

Thermal conductivity is the ability of a body to transmit heat energy from one place to another.

Since we are measuring how long it takes for heat from the hot plate to reach the wax ball, this is a typical experiment for measuring thermal conductivity. Most metals are good conductors and heat energy moves fast in them.Non-metals are poor conductors with low thermal conductivity.

A hypothetical element has two main isotopes with mass numbers of 59 and 62. If 73.00% of the isotopes have a mass number of 59 amu, what atomic weight should be listed on the periodic table for this element? Answer in units of amu.

Answers

since 73% of the isotope is given, take 100%-73% to get the remaining % of the isotopes which is going to be 27%.

hence,

atomic weight= (73×59) + (27×62)

=4307+1302

=5609 amu

Calculate the number of moles of neon gas in 8.15 x 10^24 atoms of neon gas.
1.35 moles Ne
0.135 moles Ne
135 moles Ne
13.5 moles Ne

Answers

Answer:

13.5 moles of Ne

Explanation:

1 mole of any gas contains  6.02 x 10²³ atoms of gas

6.02 x 10²³ atoms of neon is equal to 1 mole of neon .

8.15 x 10²⁴ atoms of neon is equal to  1 x 8.15 x 10²⁴ / 6.02 x 10²³ moles

= 8.15 x 10²⁴ / 6.02 x 10²³ mole o neon

= 13.5 moles of Ne .

How many moles of gold, a U, are in 3.60×10^-5 G of gold?

Answers

Answer:

See Below.

Explanation:

This is a conversion problem:

Using the molar mass of Gold (given in a periodic table) which is 196.97g/mol

you have

[tex](3.60*10^-5 g) *\frac{1moles}{196.97g}[/tex]

you always arrange the equation in a way to cancel whatever you don't want (grams) and leave what you do want (moles). Here grams cancel (top and bottom), so you're left with:

[tex]\frac{(3.60*10^-5 g) *(1)}{196.97} = 1.83*10^-7[/tex] moles of Gold

Calculate the average atomic mass of unknown element X. You determine that isotope 127X makes up 80%, isotope 126X makes up 17%, and isotope 128X makes up 3%.

A. 127.10 amu
B. 126.86 amu
C. 127.54 amu
D. 126.20 amu

Answers

Answer:

Option B. 126.68 amu

Explanation:

The following data were obtained from the question:

Isotope A (¹²⁷X):

Mass of A = 127

Abundance (A%) = 80%

Isotope B (¹²⁶X):

Mass of B = 126

Abundance (B%) = 17%

Isotope C (¹²⁸X):

Mass of C = 128

Abundance (C%) = 3%

Average atomic mass of element X =.?

Th4 average atomic mass of X can be obtained as follow:

Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

= [(127 × 80)/100] + [(126 × 17)/100] + [(128 × 3)/100]

= 101.6 + 21.42 + 3.84

= 126.68 amu

Therefore, the average atomic mass of X is 126.68 amu

Now we need to adjust coefficients in order to balance the atoms on each side of the equation. Currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

We can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

Calculate the mass (wanted measurement) of 125 mL (given measurement) of bromine.
(use the given density as the conversion factor to calculate the wanted measurement).
Sign out

Answers

Given : Density of Bromine = 3.12 g/mL
Formula : Density = Mass / Volume

Part A :
Given Volume = 125 mL
Density = Mass / Volume
So, Mass = Density x Volume
= 3.12 x 125
= 390 grams

Part B :
Given mass = 85.0 gm
Density = Mass / Volume
So, Volume = Mass / Density
= 85 / 3.12
= 27.24 mL
