What elements are in NaC2HO4 and how many atoms are in each element​

Chemistry

JulijaS [17]1 year ago

Answer:

Each molecule contains one atom of A and one atom of B. The reaction does not use all of the atoms to form compounds.

                 A + B ⟶ Product

Particles: 6      8              6

If six A atoms form six product molecules, each molecule can contain only one A atom.

The formula of the product is ABₙ.

If n = 1, we need six atoms of B.

If n = 2, we need 12 atoms of B. However, we have only eight atoms of B, so the formula of the product must be AB.

Thus, 6A + 6B ⟶ 6AB, with two B atoms left over.

A 36 gram sample of water has an initial temperature of 22 degrees Celsius after the sample absorbs 1200joules of heat energy th
UkoKoshka [18]

<span>We can use the heat equation,
Q = mcΔT </span>

 

<span>Where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J g</span>⁻¹ °C⁻<span>¹) and ΔT is the temperature difference (°C).</span>


Let's assume that the finale temperature is T.

Q = 1200 J

<span> m = 36 g
c = 4.186 J/g °C</span>

ΔT = (T - 22) 

 

By applying the formula,

   1200 J = 36 g x 4.186 J/g °C x (T - 22)

  (T - 22) = 1200 J / (36 g x 4.186 J/g °C)

  (T - 22) = 7.96 °C

            T = (7.96 + 22) °C = 29.96 °C

            T = 30 °C 


Hence, the final temperature is 30 °C.

Dahasolnce [82]

Answer:

Rate = k[NO_{2}][F_{2}]

Explanation:

  • Two reactants are present in this reaction which are NO_{2}and F_{2}
  • We know overall order of a reaction is summation of individual order with respect to reactants present in rate law equation.
  • Here, overall order of reaction is 2 including first order with respect to F_{2}
  • So, rate of reaction should also be first order with respect to another reactant i.e. first order with respect to NO_{2}
  • So, rate law: rate = k[NO_{2}][F_{2}]

Explain why you hear a “whoosh” sound when you open a can containing a carbonated drink. Which gas law applies?
Lana71 [14]

Carbonated drinks have the air under pressure so that carbon bubbles are forced into the drink, keeping it carbonated. So when you open a can, the air under pressure in the can comes out of the can at a high speed, making a "whooshing" sound. The gas law that applies to this concept is the Boyle's Law (PV=k or P1V1=P2V2).

Marina CMI [18]

Answer:

M_{acid}=0.563M

Explanation:

Hello there!

In this case, given the neutralization of the acetic acid as a weak one with sodium hydroxide as a strong base, we can see how the moles of the both of them are the same at the equivalence point; thus, it is possible to write:

M_{acid}V_{acid}=M_{base}V_{base}

Thus, we solve for the molarity of the acid to obtain:

M_{acid}=\frac{M_{base}V_{base}}{V_{acid}} \\\\ M_{acid}=\frac{33.98mL*0.1656M}{10.0mL}\\\\ M_{acid}=0.563M

Regards!
