Answer: This a redoc reaction.

The total ionic equation in separated aqueous solution will be,

$2H^+(aq)+2O^{-}(aq)+Mg^{2+}(aq)+SO_3^{2-}(aq)\rightarrow Mg^{2+}(aq)+SO_4^{2-}(aq)+H_2O(l)$

Explanation :

The given reaction is a redox reaction in which the oxygen shows reduction and sulfur shows oxidation reaction.

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

$H_2O_2(aq)+MgSO_3(aq)\rightarrow MgSO_4(aq)+H_2O(l)$

The total ionic equation in separated aqueous solution will be,

$2H^+(aq)+2O^{-}(aq)+Mg^{2+}(aq)+SO_3^{2-}(aq)\rightarrow Mg^{2+}(aq)+SO_4^{2-}(aq)+H_2O(l)$

kupik [55]

The solution 550 ml total and first we will find the amount of alcohol. 3% = 0.03 550 ml x .03 = 16.5 ml alcohol
Then to find the amount of water used, we just have to subtract the amount of alcohol from the total volume
550 ml total - 16.5 ml alcohol = 533.5 ml water

If the air temperature is the same as the temperature of your skin (about 30◦C), your body cannot get rid of heat by transferrin

Elenna [48]

Answer:

Explanation:

a )

energy produced per second = 500 J

Heat produced = 500 x .8 = 400 J per second.

If m be the mass of water evaporated per unit hour

m x latent heat = 400 x 60 x 60

= m x 2.42 x 10⁶ = 1.44 x 10⁶

m = .595 kg per hour

b )

volume of water = 595 mL

bottles = 595 / 750

.8 or 4/5 of bottle. per hour.

Oxalic Acid, a compound found in plants and vegetables such as rhubarb, has a mass percent composition of 26.7% C, 2.24% H, and

blondinia [14]

Answer:

HCO₂

Explanation:

From the information given:

The mass of the elements are:

Carbon C = 26.7 g; Hydrogen H = 2.24 g Oxygen O = 71.1 g

To determine the empirical formula;

First thing is to find the numbers of moles of each atom.

For Carbon:

$=26.7 \ g\times \dfrac{1 \ mol }{12.01 \ g} \\ \\ =2.22 \ mol \ of \ Carbon$

For Hydrogen:

$=2.24 \ g\times \dfrac{1 \ mol }{1.008 \ g} \\ \\ =2.22 \ mol \ of \ Hydrogen$

For Oxygen:

$=71.1 \ g\times \dfrac{1 \ mol }{1.008 \ g} \\ \\ =4.44 \ mol \ of \ oxygen$

Now; we use the smallest no of moles to divide the respective moles from above.

For carbon:

$\dfrac{2.22 \ mol \ of \ carbon}{2.22} =1 \ mol \ of \ carbon$

For Hydrogen:

$\dfrac{2.22 \ mol \ of \ carbon}{2.22} =1 \ mol \ of \ hydrogen$

For Oxygen:

$\dfrac{4.44 \ mol \ of \ Oxygen}{2.22} =2 \ mol \ of \ oxygen$

Thus, the empirical formula is HCO₂

The pH of a solution is measured to be pH=10. What is true of this solution?

Marta_Voda [28]

Answer:

a. the solution is a base

Explanation:

The pH range is between 0 to 14.

A solution with a pH value between 0 and 6 is said to be acidic.

A solution with pH value at 7, is said to be neutral, e.g., distilled water.

A solution with pH value between 8 and 14 is a base.

Given pH = 10, a pH value of 10 falls between the base or alkali range of the indicator
