Chemistry

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

Answer:

Percent yield of reaction is 75%.

Explanation:

Given data:

Moles of A = 2.0 mol

Moles of B = 4.0 mol

Moles of C formed = 1.8 mol

Percent yield of reaction = ?

Solution:

Chemical equation:

2A + 5B     →      3C +  D

We will compare the moles of A and B with C from balance chemical equation.

                A         :          C

                2         :           3

               B          :         C

                 5         :         3

                 4         :        3/5×4 = 2.4 mol

Number of moles of C formed by 4 moles B are less thus B is limiting reactant and will limit the yield of C.

Percent yield:

Percent yield =  actual yield /theoretical yield × 100

Percent yield = 1.8 mol / 2.4  × 100

Percent yield =75%

Help me!!!<br> Pleaseeee!!!!
Sidana [21]

Answer:

0.862 J/gºC

Explanation:

The following data were obtained from the question:

Mass of metal (Mₘ) = 50 g

Initial temperature of metal (Tₘ) = 100 °C

Mass of water (Mᵥᵥ) = 400 g

Initial temperature of water (Tᵥᵥ) = 20 °C

Equilibrium temperature (Tₑ) = 22 °C

Specific heat capacity of water (Cᵥᵥ) = 4.2 J/gºC

Specific heat capacity of metal (Cₘ) =?

The specific heat capacity of the metal can be obtained as follow:

Heat lost by metal = MₘCₘ(Tₘ – Tₑ)

= 50 × Cₘ × (100 – 22)

= 50 × Cₘ × 78

= 3900 × Cₘ

Heat gained by water = MᵥᵥCᵥᵥ(Tₑ – Tᵥᵥ)

= 400 × 4.2 × (22 – 20)

= 400 × 4.2 × 2

= 3360 J

Heat lost by metal = Heat gained by water

3900 × Cₘ = 3360

Divide both side by 3900

Cₘ = 3360 / 3900

Cₘ = 0.862 J/gºC

Therefore, the specific heat capacity of the metal is 0.862 J/gºC

A student needs exactly 1 gram of baking powder to conduct an experiment. The balance reads 0.37 grams. How
sammy [17]

Answer:

B

Explanation:

If the student needs one gram but so far only has 0.37 grams, then the amount they need is the difference between what they need and how much they already have. 1-0.37=0.63 grams.

...which isn't actually an option because none of them have decimal points but I would say it is B anyway because it is the equivalent ratio and maybe there was a typo.

Hope this helped!
