Answer:

c. because all countries around the equator experiences heat

Volume of the regular solid = l × w × h

                                              = (5 cm × 2 cm × 3 cm)

                                              = 30 cm³

Melting points of enantiomers will not compare to each other as they have same M.P. and Diastereoisomers are compared on the basis of melting point.

Stereoisomers are those isomers which are having the same molecular formula but different spatial arrangemet of atoms within the molecule.

Hence, only diastereoisomers are compared on the basis of melting point.

Explanation:

• From boyles gas law

[tex]{ \rm{P \: \alpha \: \frac{1}{V} }} \\ \\ { \rm{P _{1}V _{1} = P_{2}V _{2} }}[/tex]

[tex]{ \rm{(1 \times V _{1}) = (2 \times V _{2})}} \\ \\ { \rm{ \frac{V _{2}}{V_{1}} = \frac{1}{2} }} \\ \\ { \boxed{ \rm{V_{2} : V _{1} = \frac{1}{2} }}}[/tex]

Answer:

For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant..

Answer:

FORCE OF HAND

We know that the electron clouds of two atoms overlapping is a bond, because that signifies that the electrons are being shared in a bond.

So, I'm going to go through some definitions of these different types of bonds, because they have very specific circumstances.

A hydrogen bond is a bond between an electronegative atom and a hydrogen molecule (which is not what this question says, this isn't stated anywhere).

A dipole is a difference in electron density on two different atoms (so this isn't even close to what the question is stating, a dipole is not even a bond)

An ionic bond is an unequal sharing of electrons between two atoms (because the question doesn't state this specific fact, then it can't be this option).

By process of elimination, we know the answer is covalent bond, but just in case, we can also look at the definition of a covalent bond: a bond that involves the sharing of electrons between atoms.

That is exactly what the question is asking for! Therefore, your answer is d. covalent bond

The balanced for the reaction is:

2KI + Pb(NO₃)₂ → Pbl₂ + 2KNO₃

When the equation is balanced, the number of atoms for each element on both the reactant and product sides of the equation are equal. This can be seen below:

      Reactant   Product

K         2                 2

I          2                  2

Pb      1                    1

N       2                   2

Answer:

there would be not movement.

Explanation:

The molar mass of a compound can be calculated by finding the molar of the individual atoms that combine to make the compound.

Molar mass of compound =

         ∑ (molar mass of element × number of atoms of the element)

∴ Molar mass of dimethylglyoxime

                 = 4C + 8H + 2N + 2O

                 = [(4 × 12.011) + (8 × 1.0080) + (2 × 14.007) + (2 × 15.999)] g/mol

                 = 116.12 g/mol

Answer:The answer to your question is It will be formed 0.39 moles of H₂

Data

moles of H₂ = ?

moles of HCl = 0.78

moles of Zinc = excess

Balanced chemical reaction

             2 HCl  +  Zn  ⇒  1 H₂  +  ZnCl₂

Process

Explanation:

1.- Use proportions to solve this problem. Consider the coefficients of the balanced reaction.

              2 moles of HCl ---------------------- 1 mol of H₂

              0.78 moles of HCl -----------------  x

              x = (0.78 x 1) / 2

- Simplification

             x = 0.78 / 2

- Result

             x = 0.39 moles of H₂

We can check if the equation is balanced by comparing the number of atoms of each element on the reactant and product sides. The reaction is only balanced if the number of atoms of each element is equal.

       S  +  3O₂ → SO₃

    Reactant       Product

S        1                    1

O       6                   3

The balanced equation would be  2 S + 3O₂ → 2SO₃

                                                          Reactant       Product

                                                     S         2                   2

                                                     O        6                    6
