Answer:

Many valence electrons are shared between the atoms.

Explanation:

For the atoms to form a covalent bond, a many of the valence electrons are shared between the atoms.

When a covalent bond is to be formed, the valence electrons which are the outermost electrons are shared between the atoms that are combining.

Answer:

b.h2

i think it is.i am not sure.

Among the following the molecule which does NOT contain a covalent bond is CaO Hence correct option is (A).

Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms.

As in CaO , Ca is considered as Metal which has Electron donor nature hence it will donate electron to Oxygen.

Whereas Oxygen Considered as Non metal as it gains electron. which has electron gainer nature.

Ca donates electron and Oxygen gains electron. Thus, the bond formed between both will be the Ionic bond which is formed by the transfer of Electron.

Therefore, Among the following the molecule which does NOT contain a covalent bond is CaO Hence correct option is (A).

Answer: chemical

Explanation:

Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy. Except at absolute zero (the coldest temperature it is possible to reach), all molecules move.

Remember:

to balance equations in chemistry, you have to count the amount of atoms there are in a chemical eg:

the number of atoms in H20 are:

2 atoms of hydrogen

1 atom of oxygen (when there are no numbers by the letter it means that theres only 1 atom of it!)

The number next to a letter means the number of atoms thta it is made up of and atoms are the things it is made up of eg chocolate the ingredients are cocoa, milk and sugar ect so just like that CO2, H20 an ALL types of chemicals are made up of atoms. BUT WE WANT TO KNOW HOW MANY ATOMS- so u need to list these for all the 4 chemicals in the equation.

Im telling u this so that u can list out all of the atoms in each chemical (I will do the first two)

CH2=

1 atom of Carbon

2 atoms of hydrogen

O2=

2 atoms of oxygen

once u have listed out all the atoms from EACH of the chemicals in ur question (CH2, 02, CO2 and H20) categorise them like this

CH2

Carbon=........ Atoms

Hydrogen= .......Atoms

(Make sure the table is like vertical like lemme show u as an example. ATTACHED IS AN EXAMPLE OF WHAT UR WORK SHOULD BE SET OUT AS)

When you see the addition sign it means that elements like oxygen and hydrogen etc..basically add them up like CO2 + H20 theres oxygen in both so add up the atoms of oxygen FOR JUST CO2 AND H20 like  if there was one atom of oxygen in CO2 and 2 in h20 add them up and it makes three (1+2=3). 1 oygen  atom from CO2 plus 2 oxygen atoms in H20 that makes 3 atoms for both the chemiclas together (THIS WAS JUST AN EXMAPLE THERE ARENT ACTUALLY 2 ATOMS IN H20 OR 1 ATOM IN C02)

Look at the similarities OF ATOM NUMBERS like if CH2 has one atom of Carbon, CO2 ALSO has one atom of carbon which is fine BUT when it comes to differences u need to cross those out and PUT THAT NUMBER on both sides like if O2 has  2 atoms of oxygen and h20 has 1 that means that they need to be balanced like they either both need to be 1 atom or 2 atoms so for that u need to look attachment sorry u just need to cross them out and make them the same

make sure to write about what atoms are, to list out atoms for each chemical, compare the chemicals in both word chemicals and make them even!

Answer:

Formal charge = valance electron - nonbonding electron - (1/2)bonded electron

For nitrogen atom,

Formal charge = 5 - 2 - (1/2)×6

= 5-2-3

= 0

So, the formal charge on nitrogen atom in HCN is "0".​​​

Explanation:

The formal charge on the N atom of hydrogen cyanide, HCN molecule is 0. Option B is correct.

Formal charge is defined as the individual charge of an atom. It is represented as:

Formal charge = valance electron - nonbonding electron - (1/2)bonded electron

The valence electrons in nitrogen atom is 5, there are 2 non bonding electrons and 6 bonded electrons on N atom in HCN,

Thus, For Hydrogen cyanide molecule, the formal charge on nitrogen atom is calculated as:

Formal charge

= 5 - 2 - (1/2)×6

= 5-2-3

= 0

So, the formal charge on nitrogen atom in HCN is "0".​​​

Answer:

Insulin production would decrease.

Explanation:

Insulin and Glucagon work together to balance the sugar levels in the human blood stream. They work together in a negative feedback loop. Glucagon stimulates the liver to release glucose into the bloodstream in a process known as glycogenolysis. Insulin on the other hand is a sugar-lowering hormone.

Therefore, if glucagon secretion were permanently inhibited, insulin production would decrease as there would not be excess blood sugar to be reduced.

Answer:

Insulin production would decrease.

Answer:

V₂ = 1.41 L

Explanation:

Given data:

Initial temperature = 35°C (35 +273.15 K = 308.15 K)

Initial volume = 1.5 L

Final temperature = 17°C (17+273.15 K = 290.15 K)

Final volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 1.5 L × 290.15 K / 308.15 k

V₂ = 435.23 L.K / 308.15 k

V₂ = 1.41 L

Explanation:

The quantity of electricity : 2 Faraday = 193000 Coulomb

Given

2 moles of electrons

Required

The quantity of electricity

Solution

According to Faraday, the amount of current flowing in the electrolysis cell is closely related to the amount of substance that reacts

1 Faraday is the amount of electricity that is passed in the electrolysis cell to obtain 1 mole of electrons. 1 mole of electrons is equivalent to an electric charge of 96500 Coulombs.

The conversion / relationship can be stated as follows:

1 Faraday = 1 mole of electrons = 96500 Coulombs

1 faraday = coulomb / 96500

Can be formulated

Coulomb = Q = I. t so:

[tex]\large {\boxed {\bold {1 \: Faraday \: = \: \dfrac {i \: x \: t} {96500}}}}[/tex]

so for 2 moles electrons :

= 2 x 96500 C

= 193000 C

= 2 Faraday

Answer:

1. Qualitative.

2. Comparative investigation.

3. Mode.

Explanation:

1. Data collected that describes the quality of the data set is called qualitative data. This data type are non-numerical in nature i.e they are categorical. Some examples are excellent, poor, gender, religion etc.

2. An investigation where you compare objects to find a relationship is a comparative investigation. For example, a researcher trying to find out which bag is heavier by determining their weight.

3. If the number 5 occurs with the most frequency in the data set, it is called the mode.

For example, given A = (1, 5, 2, 5, 1, 5 4, 5). The mode is 5 because it appeared the most i.e four (4) times.

Answer:

Explanation:

Two boys were each pushing a box to the right, one boy applied a force of 3N and  the other boy applied a force of 5N.

Total force applied to the left = 3 + 5 = 8 N . The forces are added up because they act in the same direction .

Another boy was pushing the box to the left  with a force of 8N.

8 N force acts opposite to the total force of 8 N exerted by two earlier boys so

net force = 8N - 8N = 0 .

Net force on the box = 0 .

Explanation:

Scientists most especially chemists use the mole concepts through balanced chemical equations and molar masses to represent chemical reactions and account for the amount of substances.

The mole concept entails finding molar relationships between reactants and products in a chemical reaction. Mole connects difference chemical parameters and it is used in quantitative analysis of chemical reaction.
