Answer:

because the water would diloute the chemicals in the vinegar

Explanation:

Answer:

No mass of HCl could be left over by the chemical reaction because is the limting reactant and it is all consumed.

Explanation:

Our reactants are: HCl and NaOH

Products are: NaCl and H₂O

This is a neutralization reaction that can also be called an acid base reaction, an acid and a base react to produce water and a neutral salt, in this case where we have strong acid and base.

Ratio is 1:1. We convert mass to moles:

35 g . 1 mol / 36.45 g = 0.960 moles of HCl

73 g . 1 mol / 40 g = 1.82 moles of NaOH

As ratio is 1:1, for 0.960 moles of HCl we need 0.960 moles of NaOH and for 1.82 moles of NaOH, we need 1.82 moles of acid.

As we only have 0.960 moles of HCl and we need 1.82 moles, no acid remains after the reaction goes complete. HCl is the limiting reactant, so the acid, it is all consumed.

The volume can be V = 18.8 L

We solved the question using the ideal gas equation:

The formula of an ideal gas:

PV = nRT ∴ V= nRT/P

where n= 0.788 mmol = 0.788 mol (1 mmol is a thousandth of a mol)

R = R constant for ideal gases = 0.08206 Latm/Kmol

T = 17.0 ºC = (17.0 + 273) K = 290 K

and V = volume in liters our unknown

Plugging our values and solving for V,

V = 0.788 mol x 0.08206 Latm/Kmol x 290 K / 1atm = 18.8 L

Answer:

6H2 + P4→ 4PH3

Explanation:

Phosphorus has 4 in it and hydrogen has 3 in it. in order to balance it, we have to put 4 in front of phosphine so that the phosphorus on the product side has an equal amount as to the one on the reactant side.

the only one left to balance is hydrogen and so in order to balance it we put a 6 on h2 because the hydrogen in the product size becomes 12 (4 * 3).

therefore the hydrogen on the reactant side becomes 12 as well (6 * 2)

The balanced chemical reaction is:

                      \(6H_2(g)+P_4(s)\rightarrow 4PH_3(g)\)

Explanation:

The silica content and viscosity of the magma increase as it rises through the continental crust, finally generating andesitic-rhyolitic magmas as a result of partial melting of the crust. That's accurate.

Stratovolcanoes frequently release thick lava flows made of andesite magma, some of which can be several kilometers long. Strong explosive eruptions from andesite magma can also result in pyroclastic flows, surges, and massive eruption columns. At temperatures between 900 and 1100 ° C, andesites erupt.

Wet partial melting of the mantle results in the formation of andesitic magma. Water is in contact with the mantle beneath the ocean. The mantle will heat up and water will be forced into it when subduction, or continental plates sliding apart, takes place.

Explanation:

We need to find how many half lives are required to reach .0313

.0313 = 1/2^n    log both sides and solve for n

log.0313 / log (1/2 )   = n     where n= NUMBER of halflives

n = ~ 5 half lives

   these 5 half lives took up 65 minutes

       so EACH half life is 65/5 = 13 mins

As a result, the ideal gas law is applied, and the pressure of the gas in the container is 1.44 atm.

The Kelvin temperature and hence the volume are going to be in direct proportion when the pressure on a sample of a dry gas is held constant, according to the definition of the Charles Law Formula. PV = k is the law's equation, and k might be a constant.

This issue can be resolved by applying the ideal gas law:

PV = nR

T = -52 °C + 273.15 = 221.15 K

n = 0.642 mol

V = 8.6 L

T = 221.15 K

\(R = 0.0821 L·atm/mol·K (gas constant for ideal gases)\)

PV = nRT

P = nRT/V

P = (0.642 mol)(0.0821 L·atm/mol·K)(221.15 K)/(8.6 L)

P = 1.44 atm

The volume (in mL) of the 1.6 M NaHCO₃ solution that must be poured on the spill to react completely is 286 mL

We'll begin by writing the balanced equation for the reaction. This is given below:

H₂SO₄ + 2NaHCO₃ —> Na₂SO₄ + 2H₂O + 2CO₂

The volume of NaHCO₃ can be obtained as follow:

MaVa / MbVb = nA / nB

(2.6 × 88) / (1.6 × Vb) = 1  /2

228.8 / (1.6 × Vb) = 1 / 2

Cross multiply

1.6 × Vb = 228.8 × 2

1.6 × Vb = 457.6

Divide both side by 1.6

Vb = 457.6 / 1.6

The revolution also allowed farmers to grow and produce more food and transport it to where it was needed.

Explanation:

The Kc for the reaction would be zero.

The balanced equation for the reaction is:

CS2(g) + 3Cl2(g) ⇌ S2Cl2(g) + CCl4(g)

The equilibrium constant expression for the reaction is:

Kc = [S2Cl2][CCl4]/[CS2][Cl2]^3

At equilibrium, the concentrations can be calculated as follows:

[CS2] = 0.12 mol/10.0 L = 0.012 M

[Cl2] = 0.36 mol/10.0 L = 0.036 M

[S2Cl2] = 0 M (initially)

[CCl4] = 0.090 mol/10.0 L = 0.0090 M

Substituting the values into the equilibrium constant expression:

Kc = [(0)(0.0090)]/[(0.012)(0.036)^3] = 0

The correct way to compute the oxygen that reacted is by considering the mass of hydrogen, 58.9 g, its molar mass, 2.02 g/mol, the 2:1 mole ratio between hydrogen and oxygen and the atomic mass of that gaseous oxygen 32.00 g/mol; therefore we use the following stoichiometric procedure:

\(m_{O_2}=58.9gH_2*\frac{1molH_2}{2.02gH_2}*\frac{1molO_2}{2molH_2} *\frac{32.00gO_2}{1molO_2} \\\\m_{O_2}=467gO_2\)
