Answer:

The balanced equation is:

2 NaCl + H₂SO₄ ---> Na₂SO₄ + 2 HCl

Explanation:

For balance the chemical equation, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts

Left side: 1 sodium Na, 1  chlorine Cl, 2 hydrogen, 1 sulfur S and 4 oxygen.

Right side: 2 sodium Na, 1  chlorine Cl, 1 hydrogen, 1 sulfur S and 4 oxygen.

The coefficients of each molecule below indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction. So,  in this case, since all the coefficients are 1, the quantity of each element on each side of the reaction is maintained.

Since the amount of sodium Na is different on each side of the reaction, the equation will be balanced as follows:

2 NaCl + H₂SO₄ ---> Na₂SO₄ + HCl

Now you have:

Left side: 2*1=2 sodium Na, 2*1=2  chlorine Cl, 2 hydrogen, 1 sulfur S and 4 oxygen.

Right side: 2 sodium Na, 1  chlorine Cl, 1 hydrogen, 1 sulfur S and 4 oxygen.

Since the amount of chlorine Cl is different on each side of the reaction, the equation will be balanced as follows:

2 NaCl + H₂SO₄ ---> Na₂SO₄ + 2 HCl

Now you have:

Left side: 2*1=2 sodium Na, 2*1=2  chlorine Cl, 2 hydrogen, 1 sulfur S and 4 oxygen.

Right side: 2 sodium Na, 2*1=2  chlorine Cl, 2*1=2 hydrogen, 1 sulfur S and 4 oxygen.

Note that you finally get the same amount of each element on each side of the reaction. So<u><em> the balanced equation is:</em></u>

<u><em>2 NaCl + H₂SO₄ ---> Na₂SO₄ + 2 HCl</em></u>

If 0.507J of heat leads to a 0.007 degree C change in water, what mass is present?
Mamont248 [21]

Answer:

17.3 g

Explanation:

<u>Given the following data;</u>

  • Quantity of heat, Q = 0.507 J
  • Temperature = 0.007°C
  • Specific heat capacity of water = 4.2 J/g°C

Mathematically, Heat capacity is given by the formula;

Q = MCT

Where;

  • Q represents the heat capacity or quantity of heat.
  • M represents the mass of an object.
  • C represents the specific heat capacity of water.
  • T represents the temperature.

Making "M" the subject of formula, we have;

M = \frac {Q}{CT}

Substituting the values into the formula, we have;

M = \frac {0.507}{4.2*0.007}

M = \frac {0.507}{0.0294}

<em>Mass, m = 17.3 grams</em>

Write a net ionic equation to show that hydroiodic acid, hi, behaves as an acid in water.
OlgaM077 [116]

Answer:

HI(aq) + H₂O(ℓ) ⟶ H₃O⁺(aq) + I⁻(aq)

Explanation:

The HI donates a proton to the water, converting it to a hydronium ion

HI(aq) + H₂O(ℓ) ⟶ H₃O⁺(aq) + I⁻(aq)

Thus, the HI is behaving like a Brønsted acid.

Calculate the mass in micrograms of zinc oxalate the chemist has added to the flask. be sure your answer has the correct number
Vera_Pavlovna [14]
<span>A chemist adds 155.0ml of a 4.10 X 10^-5 mmol/L of a zinc oxalate (ZnC2O4)solution to a reaction flask. Calculate the mass in micrograms of zinc oxalate the chemist has added to the flask. 1mmol = 10^-3 mol Therefore 4.10*10^-5mmol = 4.10*10^-8mol molar mass ZnC2O4 = 65.39+(2*12.011)+(4*15.99) = 153.372g/mol You have 4.10*10^-8 mol/litre =153.372 * 4.10*10^-8 = 6.29*10^-6 grams / litre (* see below) But you have 155ml. Mass of ZnC2O4 = 155/1000*6.29*10^-6 g Mass is = 9.75*10^-7 grams 1µg = 10^-6 g You then have 9.75*10^-7/10^-6 = 0.975µg ZnC2O4 (*see below) at this point you could have said: 1µg = 10^-6 g therefore you have a solution of 6.29µg per litre, 155ml = 6.29*155/1000 = 0.975µg ZnC2O4</span>
