Answer:

We'll have 1.00 mol H2

Explanation:

Step 1: Data given

Number of moles of Mg = 1.00 moles

Step 2: The balanced equation

Mg(s) + H2SO4(aq) → MgSO4(aq) + H2(g)

Step 3: Calculate moles of H2

For 1 mol Mg we need 1 mol H2SO4 to produce 1 mol MgSO4 and 1 mol H2

We'll have 1.00 mol H2

What type(s) of intermolecular forces are expected between ch3ch2ch2ch2ch2oh molecules?

notka56 [123]

Answer : Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

Explanation :

The given molecule is, $CH_3CH_2CH_2CH_2CH_2OH$

Three types of inter-molecular forces are present in this molecule which are Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

Hydrogen-bonding : when the partial positive end of hydrogen is bonded with the partial negative end of another molecule like, oxygen, nitrogen, etc.

Dipole-dipole attraction : When the partial positively charged part of the molecule is interact with the partial negatively charged part of the molecule. For example : In case of HCl.

London-dispersion force : This force is present in all type of molecule whether it is a polar or non-polar, ionic or covalent. For example : In case of Br-Br , F-F, etc

Hydrogen-bonding is present between the oxygen and hydrogen molecule.

Dipole-dipole forces is present between the carbon and oxygen molecule.

London-dispersion forces is present between the carbon and carbon molecule.

How many moles of Pb(NO3)2 are required

yarga [219]

Answer:

12 moles Pb(NO₄)₂ needed.

Explanation:

3Pb(NO₃)₂ +2AlCl₃ => 3PbCl₂ + 2Al(NO₃)₃

Given => ? moles 8 moles

from reaction stoichiometry, 2 moles AlCl₃ requires 3 moles Pb(NO₄)₂ then 8 moles AlCl₃ requires 3/2(8) moles of the Pb(NO₄)₂ => 12 moles Pb(NO₄)₂ needed.

A common anesthetic in dentistry known as nitronox consists of a mixture of dinitrogen oxide, n2o, and oxygen gas, o2, which is

Nesterboy [21]

Anesthetic in dentistry consists of a mixture of dinitrogen oxide (N₂O) and oxygen gas (O₂), which is administered through an inhaler over the nose. Total pressure of the mixture ( $P_{total}$ ) is sum of partial pressure of N₂O ( $p_{N_{2}O }$ ) and partial pressure of O₂, ( $p_{O_{2} }$ ).

$P_{total}=p_{N_{2}O } + p_{O_{2} }$

$P_{total}= 740 mmHg, p_{O_{2} }$ =370 mmHg

So, $p_{N_{2}O }$ = (740-370) mmHg= 370 mmHg=370 torr

Hence, partial pressure of N₂O is 370 torr.

As, 1mmHg= 1 torr.
