Answer:

Sn(C2H3O2)2

Explanation:

C2H3O2 is Acetate

Sn is tin

Acetate has a -1 charge

In order for tin to have a +2 charge, we need two acetates

So we write it as (C2H3O2)2

You just leave Sn blank because of the roman numeral and since it is a transition metal.

So the answer is Sn(C2H3O2)2

Answer:

$\boxed {\boxed {\sf Sn (C_2 H_3 O_2)_2}}$

Explanation:

First, find what tin and acetate is.

Acetate: C₂H₃O₂
Tin: Sn

Next, find the charge on acetate, which is -1.

The Roman Numeral 2 in parentheses after tin (II), signifies that the tin has a charge of +2.

We need to balance the charges, so they will equal 0.

1 acetate= -1
Tin = +2

The best way to balance is by using 2 acetate molecules

2 acetate = -2
Tin = +2
-2 +2=0

If we want 2 acetate molecules, we must add a subscript of 2 after acetate.

Acetate: C₂H₃O₂

2 Acetate: (C₂H₃O₂)₂

Add the tin (Sn) in front

Tin (II) Acetate: Sn (C₂H₃O₂)₂

The formula for tin (II) acetate is Sn (C₂H₃O₂)₂

How many grams of zinc would be required to produce 9.65g of zinc hydroxide

Effectus [21]

The question is incomplete, here is the complete question:

How many grams of zinc would be required to produce 9.65g of zinc hydroxide

Zn+2MnO₂+H₂O→Zn(OH)₂+Mn₂O₃

<u>Answer:</u> The mass of zinc required is 6.35 grams

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

Given mass of zinc hydroxide = 9.65 g

Molar mass of zinc hydroxide = 99.4 g/mol

Putting values in equation 1, we get:

$\text{Moles of zinc hydroxide}=\frac{9.65g}{99.4g/mol}=0.0971mol$

The given chemical equation follows:

$Zn+2MnO_2+H_2O\rightarrow Zn(OH)_2+Mn_2O_3$

By Stoichiometry of the reaction:

1 mole of zinc hydroxide is produced from 1 mole of zinc

So, 0.0971 moles of zinc hydroxide will be produced from = $\frac{1}{1}\times 0.0971=0.0971mol$ of zinc

Now, calculating the mass of zinc from equation 1, we get:

Molar mass of zinc = 65.4 g/mol

Moles of zinc = 0.0971 moles

Putting values in equation 1, we get:

$0.0971mol=\frac{\text{Mass of zinc}}{65.4g/mol}\\\\\text{Mass of zinc}=(0.0971mol\times 65.4g/mol)=6.35g$

Hence, the mass of zinc required is 6.35 grams

What is the mass of 3.25 mol of h2so4

Setler [38]

Answer/ explanation :

The find the mass,

We use this formula

Number of mole = mass/ molar mass

Since number of mole = 3.25mol

Number of mass be x

Molar mass of H2SO4

H - 1.00784 * 2= 2.01568

S - 32.065

O - 15.999 * 4 = 63.996

Note there are 2 moles of H and 4 moles of O and 1 mole of S

Molar mass of H2SO4 = 2.01568 + 32.065 + 63.996

= 98.07668g/mol

Number of mole= 3.25mol

3.25 = x / 98.07668

x = 3.25 * 98.07668

= 318.749g

Therefore, the number of mass is 318.749g

Method A: Does not transfer heat through solids and requires a medium for heat transfer Method B: Requires a material medium and

Paha777 [63]

Method A is Convection

Method B is Conduction

Explanation:

From the problem, we can infer that method A is convection and method B is conduction.

Conduction, convection and radiation are the three main methods of heat transfer.

Conduction and convection requires material medium to propagate.
Radiation occurs in the absence of a material medium.
Conduction mostly occurs in solid. Here, heat is transferred from one hot end to the cold end of the solid. The vibration of the particles in the hot end causes the transfer of kinetic energy to the cold end until thermal equilibrium is reached.
In convection, heat is primarily transferred in fluids as a result of density differences. Convection involves the motion of the materials of the medium. Hot air is light and it rises whereas cold air is dense and it sinks.
