Answer:

It is one of the covalent bonds in which the electrons are shared equally; therefore, dipole moment exists between the atoms in a molecule and there is no charge separation between the atoms in a molecule.

Hydrolamine ,NH2OH , is a reducing agent found in some film developing solutions. How many hydrogen atoms are in 1.80moles of hy

kolezko [41]

Answer:

number of hydrogen atom in 1.8 mole of NH2OH = $9.8\times 10^{22}$

Explanation:

percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule

= $\frac{3\times 1}{14+3+16}$ \times 100

= 9.09 percentage

therefore number of moles in 1.8 moles of hydroxy amine = $\frac{9.09}{100}\times 1.8$

= .16 moles of hydrogen

number of hydrogen atom = (number of moles )×(avagadro number)

= $9.8\times 10^{22}$ atoms of hydrogen

The natural gas in a storage reservoir, under a pressure of 1.00 atmosphere, has a volume of 2.74 × 109 L at 20.0°C. The tempera

Soloha48 [4]

Answer : The final volume of gas will be, $2.36\times 10^9L$

Explanation :

Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$

or,

$\frac{V_1}{V_2}=\frac{T_1}{T_2}$

where,

$V_1$ = initial volume of gas = $2.74\times 10^9L$

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $20.0^oC=273+20.0=293K$

$T_2$ = final temperature of gas = $-20.0^oC=273+(-20.0)=253K$

Now put all the given values in the above formula, we get the final volume of the gas.

$\frac{2.74\times 10^9L}{V_2}=\frac{293K}{253K}$

$V_2=2.36\times 10^9L$

Therefore, the final volume of gas will be, $2.36\times 10^9L$

In a double-replacement reaction, there are two reactants and ____________________ product(s

bixtya [17]

Answer:

Two

Explanation:

In a double-replacement reaction, there will be two reactants and two products.

It is called double replacement reaction because one element in reactant 1 replaces an element in reactant 2 and other element in reactant 2 replaces other element in reactant 1.

Here two replacements are taking place. Hence, this is called double replacement reaction.

A Neutralization reaction i.e an Acid - Base reaction is a good example of Double replacement reaction.

An Example is provided below for better understanding :

HNO3 + NaOH --> NaNO₃ + H₂O.

Here HNO₃ is the acid and NaOH is the base which are the reactants.

NaNO₃ and H₂O are the products.

This is a double replacement reaction because,

Hydrogen(H) in HNO₃ replaces Sodium(Na) in NaOH, and

NO₃ in HNO₃ replaces OH in NaOH.

Here, there are 2 reactants and 2 products.
