If we have 6.68% NaClO, it is the same as saying--> 6.68 grams NaClO= 100 mL of solution. we can use this as a conversion. 

800. mL (6.68 mL/ 100 mL)= 53.4 mL

solution = solute + solvent

solute= NaClO
solvent= H2O

solvent= 800-53.4= 747 mL of H2O

so, we you need 53.4 mL of NaClO and 747 mL of water or 53.4 grams of NaClO and 747 mL of water

Lorico [155]
M=43lb = 19,5kg

If 115mg --------- is for --------- 1kg
                             so
    x        ---------- is for --------- 19,5kg

x = 19,5kg * 115mg / 1kg
x = 2242,5 mg

Coal, which is primarily carbon, can be converted to natural gas, primarily CH4, by the following exothermic reaction: C(s)+2H2(
LuckyWell [14K]

Answer:

A. The reaction will proceed forward forming more CH4

B. The reaction will proceed forward forming more CH4

C. Since the reaction is exothermic, raising the temperature will cause the reaction to proceed backward, thus forming C and H2.

D. Lowering the volume makes the gas particles to be more close together thereby enhancing their collisions leading to reaction. Therefore the reaction will proceed forward forming more CH4

E. Catalyst only reduce the activation energy so the reaction can proceed faster. The reaction will proceed forward forming.

F. The following will favour CH4 at equilibrium

i. Catalyst to the reaction mixture,

ii. Both adding more H2 to the reaction mixture and lowering the volume of the reaction mixture

iii. Adding more C to the reaction mixture.

When iron metal reacts with sulfuric acid, it produces iron (III) sulfate and hydrogen gas. Balance the equation: Fe + H2SO4 → F
mel-nik [20]
<h3>Answer:</h3>

2Fe(s) + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂(g)

<h3>Explanation:</h3>

The equation for the reaction between iron metal and sulfuric acid is given by;

Fe(s) + H₂SO₄ → Fe₂(SO₄)₃ + H₂(g)

We are supposed to balance the equation:

What do we mean by balancing a chemical equation?

  • Balancing a chemical equations means that we want to make sure the number of atoms of each element is the same on both sides of the equation.

How is balancing done?

  • Balancing of chemical equations is try and error process that is done by putting appropriate coefficients on the reactants and products to equate the number of atoms of each element.

Why are subscripts on the compounds not changed?

  • Subscripts in a compound show the actual number of atoms of each element in the compound and therefore can never be altered with because it will distort the chemical compound.

Why is it necessary to balance chemical equations?

  • Chemical equations are balanced for them to obey the law of conservation of mass.
  • According to this law, the mass of the reactants should be equal to the mass of products, which is achieved through balancing an equation.

What is the required balanced equation?

  • The equation given can be balanced by putting the coefficients 2, 3, 1, 3 in that order on the reactants and products.
  • Therefore, the balanced chemical equation is;

2Fe(s) + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂(g)

A weather balloon has a volume of 750ml when filled with helium at 8c at a pressure of 380torr. What is the new volume of the ba
DerKrebs [107]

Answer:

Using general gas laws

P1V1/T1 = P2V2/T2

Where P1=380torr = 380mmHg

Vi = 750ml = 0.75dm3

T1= 8c = 281k

P2=0.2torr= 0.2mmHg

T2= 75c = 348k

V2=?

(380*0.75)/281 = (0.2*V2)/348

V2= 1764.77
