Answer:

In a polar covalent bond, the more electronegative atom pulls electrons closer and gains a slightly negative charge, while the less electronegative atom has a slightly positive charge.

Explanation:

The covalent bond is the chemical bond between two atoms where electrons are shared. This makes the atoms behave as a unit, which we call a molecule. Atoms interact with each other through the outermost electrons forming bonds.

In other words, the covalent bond is formed by sharing a pair of electrons between the two atoms, one coming from each atom. The shared pair of electrons is common to the two atoms and holds them together. So molecules are formed: small groups of atoms linked together by covalent bonds.

In covalent bonds a dipole forms. The atom with the highest electronegativity attracts electrons towards itself, forming a negative dipole around it since the electrons have a negative charge. In the atom with lower electronegativity, the dipole formed is positively charged, since it partially gives up its electrons.

This is, in a polar covalent bond, the more electronegative atom pulls electrons closer and gains a slightly negative charge, while the less electronegative atom has a slightly positive charge.

Answer: The statement that is not a determining factor in formation of intrusive igneous rocks is 'None of the above' and Magma cools very fast beneath the Earth's surface.

Explanation:

Rocks are naturally occurring solid materials that are made up of different types of minerals which affects it's texture and colours. The three main types of rocks are:

--> sedimentary rocks,

--> metamorphic rocks and

--> igneous rocks.

Igneous rocks are formed from the crystallization and solidification of hot molten rocks which originates from deep within the earth. Depending on where the molten rock solidifies, the igneous rock is divided into two, namely:

--> intrusive igneous rock and

--> extrusive igneous rock.

The INTRUSIVE IGNEOUS rocks are formed within or deep beneath the earth surface when the hot magma SLOWLY cools over millions of years until it solidifies. The slow cooling allows large crystals to grow.

Therefore the statements (None of the above and Magma cools very fast beneath the Earth's surface) are not a determining factor.

Explanation:

Nobel gasses are not reactive and are the far right group on the periodic table.  This is because they have a full valence electron shell which is the most stable electron configuration.  Most reactions occur in order for an atom to fill its valence shell and since they already have a full valence shell there is no reason for them to react.

Physical change occur when objects or sub undergo a change that does not change their chemical composition.

Chemical change us a permanent change which occur when a substance combined with another to form a new substances.

Answer:

41.63g

Explanation:

Given parameters:

Volume of CaCl₂  = 500mL  = 0.5L

Concentration  = 0.75mol/L

Unknown:

Mass of the solute needed = ?

Solution:

The mass of the solute can be derived using the expression below;

     Mass  = number of moles x molar mass

But,

   Number of moles  = Concentration x Volume

So;

     Mass  = Concentration x Volume x molar mas

Molar mass of CaCl₂  = 40 + 2(35.5) = 111g/mol

     Mass  = 0.75 x 0.5 x 111 = 41.63g

Answer:

2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2

Explanation:

The balanced reaction equation is shown below;

2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2

This reaction is possible because the reduction potential of Rb is -2.98V while that of Ba is –2.92 V. Hence Rb can displace Ba from its salt solution.

The equation is balanced since the number of atoms of each element on the left and right hand sides of the reaction equation are equal.

The products for the reaction of Rubidium nitrite and Barium carbonate has been Barium nitrite and Rubidium carbonate.

Rubidium nitrite has been the binary ionic compound found to be acidic in nature. While barium carbonate has been the basic salt with the potency to be poisonous to humans.

The reaction between an acid and a base has been the neutralization reaction with the formation of salt and water. The reaction between rubidium nitrite and barium carbonate will be:

The reaction has been the displacement reaction with the tendency to displacement.

When halogens react with metals,they form salts called metal halides according to their electronic configuration according to which reaction takes place.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Answer:

Explanation:

An element's location in the periodic table is largely depending on its electrons. The number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element's block. Sometimes during these groups there are more like the alkali metals the non metals and gases :)

Answer:

1.) 12 tablespoons of sugar and 3 cups of water (48 tablespoons)

2.) Amount of lemon juice, sugar and water required will be = 0.375 cups, 0.75 cups and 3 cups.

Step-by-step explanation:

Malanie is making lemonade and finds a recipe that requires lemon juice, sugar and water in the ratio of 1 : 2 : 8.

She juices 2 lemons to obtain 6 tablespoons of lemon juice.

∵ 16 tablespoons = 1 cup

∴ 1 tablespoon =  cup

∴ 6 tablespoon =   cup =  0.375 cups

Since ratio between lemon and sugar is 1 : 2

So amount of sugar required = 0.375×2 = 0.75 cups

Ratio between lemon and water is 1 : 8

So amount of water required = 0.375×8 = 3 cups

Therefore, amount of lemon juice, sugar and water required = 0.375 cups, 0.75 cups sugar and 3 cups respectively.

Answer:

18 cups.
