When 1.98 g of NaOH (molar mass= 40 g/mole) are added to 75.0 mL of a 0.350 M HCl solution in a coffee-cup calorimeter, the temp

Wittaler [7]

Answer:

(ΔHrxn) = 1.273kJ/mol

Explanation:

Applying

m=78.2, c= 3.97, ∆t= 25.8-21.7

(ΔHrxn)= mc∆t

=78.2× 3.97× 4.1= 1.273kJ/mol

How many molecules of water will be produced if 52.6 g of methane are burned?

dem82 [27]

When the balanced reaction equation of methane combustion is:

CH4 + 2O2 →CO2 + 2H2O

so, we can see that each 1 mole of methane combusted will give 2 moles of water as a product.

so first, we need to get the moles of methane =

= mass of methane /molar mass of methane

= 52.6 g / 16.04 g/mol

= 3.28 moles

when 1 mol of methane produces→ 2 moles of water

∴ 3.28 moles methane produces → X moles of water

∴ moles of water = 3.28 * 2

= 6.56 moles

when each 1 mole of water has 6.02 x 10^23 (Avogadro's number ) individual molecules:

∴number of molecules of water = 6.56 * 6.02 x 10^23

= 3.9 x 10^24 molecules

what type of structural isomerism arises when a particular ligand is capable of coordinating to a metal in two ways?

aivan3 [116]

The type of structural isomerism arises when a particular ligand is capable of coordinating to a metal in two ways is linkage isomer.

<h3>What are structural isomerism?</h3>

Structural isomerism is a kind of isomerism in which molecular formula of the compound is same but they all have different arrangement of atoms or bonding in them.

If in any compound particular ligand is attached to the metal through different sides of the compound, then the product which is formed by these arrangement is known as linkage isomers.

Example of the linkage isomer is attached below.

Hence, the required isomerism is linkage isomerism.
