Which of the following elements has the strongest ionization energy: Mg or Cl? Define ionization

Chemistry

1 answer:

Mila [183]3 years ago

Answer:

Explanation:

The element Cl will have the strongest ionization energy from the given choices. Most non-metals have higher ionization energy compared to metals.

Ionization energy is the energy required to remove the most loosely held electron from the gaseous phase of an atom.

As you go from left to right on the periodic table, it increases progressive
From top to bottom, the ionization energy reduces significantly.
The attractive force between the protons in the nucleus and the electrons plays a very important role.
In metals, they have very large atomic radius, the attractive force on the outer electrons is very weak.
This is not the case in non-metals

PLEASE HELPP ______ consist of one large main root with smaller roots branching off, while _____ consist of several main roots t

Kay [80]

fibrous roots; taproots

Explanation:

A taproot root consists of one large main root with smaller roots that branches off into the soil, while the fibrous roots consists of several main roots that branches off to form one mass of roots.

The root system in plants helps them to absorb water and other nutrients from the soil.
A taproot is much more like extension of stem that penetrates into the ground.
It tapers at the end with many other smaller roots branching and networking from it.
The fibrous root is a series of roots directly from the stem that independent of one another.
Roots are used by plants for anchorage into the soil.

An inflatable toy starts with 1.05 moles of air and a volume of 5.17 liters. When fully inflated, the volume is 8.00 liters. If

padilas [110]

Answer:- 1.62 moles

Solution:- At constant temperature and pressure, volume is directly proportional to the moles of the gas.

$\frac{V_1}{V_2}=\frac{n_1}{n_2}$

from given data, $V_1$ = 5.17 L, $n_1$ = 1.05 moles

$V_2$ = 8.00 L, $n_2$ = ?

Let's plug in the values in the formula:

$\frac{5.17L}{8.00L}=\frac{1.05moles}{n_2}$

On cross multiply:

$n_2=\frac{8.00L(1.05moles)}{5.17L}$

$n_2$ = 1.62 moles

So, now the toy contains 1.62 moles of the air.

Which metal is more active than NI and less active than Zn?

Mademuasel [1]

Answer : The correct option is, (2) Cr (Chromium)

Explanation :

The reactivity series of metal are arranged of the reactivity from the highest to the lowest. Reactivity series is used to determine the products of the single displacement reactions. In the single displacement reaction, the most reactive metal displaces the least reactive metal.

From the given reactivity series we conclude that there are two metal (Mg and Cr) are more reactive metal than the Ni and there are two metal (Pb and Cr) are less reactive metal than the Zn. So, the Cr (Chromium) is the metal which is more active than Ni and less active than Zn.

Hence, the correct option is, (2) Cr
