Which two elements have the most similar chemical properties?
Sedbober [7]

atoms are made of 3 types of sub atomic particles- protons, neutrons and electrons

from these 3 particles, electrons are responsible for participating in chemical bonds. therefore chemical properties of elements are based on the number of electrons present.

valence electrons are the number of electrons in the outermost energy shell that are involved in chemical bonds.

atoms with same number of valence electrons are grouped in to columns called groups.

therefore elements of the same group have same number of valence electrons, hence similar chemical properties.

from the options given

only Be and Mg belong to the same group they both belong to group 2 with 2 valence electrons

therefore Be and Mg have similar chemical properties

answer is

1) Be and Mg

You are given two closed containers. Each containing a liquid solvent. Ammonia and table salt will dissolve in container A. Hexa
snow_tiger [21]
Ammonia and table salt dissolves in polar solvents, so A is water,
CO2 and hexane are non-polar substances, so they are going to be dissolved in non-polar solvent, so I think it is going to be carbon tetrachloride

Answer is <span>A) A - water; B - carbon tetrachloride

Table salt does not dissolve in oil and CCl4, and Br2 is too active and it is going to react with NH3.</span>

_Na+ Cl2 - -&gt; _NaCl<br><br> A 2,4<br> B 1,2<br> C 3,3<br> D 2,2
Natali [406]

Answer:

D 2,2

Explanation:

We can see that there are 2 chlorines on the reactant side so there has to be a 2 on the product side

Now we have Na + Cl2 --> 2NaCl

The problem now is that there are 2 sodiums on the product side so add a 2 to the Na on the reactant side

2Na + Cl2 --> 2NaCl

Now it's balanced!

density = mass/volume

density = 10/24

density = 0.416 g/cm³

Q.2-

Given,

mass - 700grams

volume - 1100cm³

density = mass/volume

density = 700/1100

density = 0.6363 g/cm³
