Use the following Balanced Equation to complete the question: 2 Al + 6 HBr → 2 AlBr3 + 3 H2

If you have 10 moles of Al how many moles of H2 can be produced?


*Will give Brainly!*

Answer:

b)The molar mass of the particles.

Explanation:

The rate of effusion of a gas is inversely proportional to the square root of its molar mass (Graham's law), a relationship that closely approximates the rate of diffusion. As a result, light gases tend to diffuse and effuse much more rapidly than heavier gases.

Answer:

K = 0.0209

Explanation:

K = [tex]\frac{[H_{2}][I_{2}]}{[2HI]^{2}}[/tex]

K = [tex]\frac{[4.35 x 10^{-2} ][2.79 x 10^{-2} ]}{[0.241]^{2} }[/tex]

K = 0.0208958

K = 0.0209

Explanation:

The reaction between HNO₃ and KOH is:

First we calculate how many KOH moles reacted with the diluted HNO₃ sample, using the given volume and concentration:

As 1 KOH mol reacts with 1 HNO₃ mol, in 25 mL of the diluted HNO₃ solution there are 30 HNO₃ mmoles.

With that information in mind we can calculate the HNO₃ concentration in the diluted solution:

Finally we can use the C₁V₁=C₂V₂ formula to calculate the concentration of the original solution:

Answer:

[tex]a=1.134\frac{m}{s^2}[/tex]

Explanation:

Hello there!

In this case, by considering the physical definition of force in terms of mass and acceleration:

[tex]F=m*a[/tex]

Given the generated force and the involved mass, we can compute the required acceleration as shown below:

[tex]a=\frac{F}{m}\\\\a=\frac{2552N}{114kg}[/tex]

Yet it is necessary to break out Newtons to:

[tex]a=\frac{2552\frac{kg*m}{s^2} }{114kg}\\\\a=1.134\frac{m}{s^2}[/tex]

Answer:Explanation:

250.ml of a 0.400 divide

Answer:

nah

Explanation:

Answer:

a. 25.7mL are necessaries.

b. 1.964g of salicylic acid can be isolated.

Explanation:

a. As the solubility of salicylicic acid in boiling water is 77.8g/L, to dissolve 2.0g of salicylic acid are necessaries:

2.0g * (1L / 77.8g) = 0.0257L =

b. Then, at 10°C the solution just can dissolve 1.4g/L, that is:

0.0257L * (1.4g/L) = 0.036g of salicylic acid are dissolved.

And will precipitate:

2.0g - 0.036g =

Answer:

Covalent bonds

Explanation:

A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.

Answer:

c 0.40 L

Explanation:

Calculate by using Boyle's Law P₁V₁=P₂V₂

(0.14atm)(2.4L) = (0.84atm)(V₂)

0.336 atmL = (0.84atm)(V₂)

V₂ = 0.336 atmL/0.84atm

V₂ = 0.4 L

Answer:

P4O10 + 6H2O → 4H3PO4         ΔH = 453 kJ

Explanation:

A thermochemical reaction is one in which the amount of heat gained/evolved is written as part of the reaction equation.

A thermochemical equation helps us to judge whether an equation is endothermic or exothermic. For an endothermic reaction, ΔH  is positive while for an exothermic reaction ΔH is negative.

Since, the reaction of one mole of P4O10(s)  with H2O(l) to form H3PO4(aq) evolves 453 kJ of energy for each mole of P4O10(s) that reacts. Then we can write;

P4O10 + 6H2O → 4H3PO4         ΔH = 453 kJ

Answer:

B. Nuclear fission reactions use only a small amount of material to

produce a large amount of energy.

C. Nuclear reactors use controlled reactions.

Explanation:

Nuclear reactors are devices that contain and control nuclear chain reactions while releasing heat produced from these nuclear chain reactions at a controlled rate.

A nuclear power plant uses the enormous amount of heat that are produced from the nuclear chain reactions occurring in the nuclear reactor to turn water into steam, which then drives turbine generators that generate electricity.

The nuclear chain reactions occurring in the nuclear reactor are fission chain reactions. A nuclear fission reaction is a reaction in which a larger atom is split into two or more smaller atoms when bombarded with energetic neutrons resulting in the release of large amounts of energy and more neutrons. The neutrons released split more atoms of the larger atom into smaller atoms in what is known as a chain reaction. This reaction is controlled by means of moderators. A moderator helps slow down the neutrons produced by fission to sustain the chain reaction.

Statements that are right as regards nuclear energy and reactors are ;

B. Nuclear fission reactions use only a small amount of material to

produce a large amount of energy.

C. Nuclear reactors use controlled reactions.

Therefore option B,C, are correct.

Answer:

[tex]T_F=17.56\°C[/tex]

Explanation:

Hello there!

In this case, for this calorimetry problem, it is possible for us to realize that the heat lost by the hot silver is gained by the cold far whose specific heat is 3.94 J/g°c, so we can write:

[tex]-Q_{Ag}=Q_{fat}[/tex]

Which can be written in terms of mass, specific heat and temperature as shown below:

[tex]-m_{Ag}C_{Ag}(T_F-T_{Ag})=m_{fat}C_{fat}(T_F-T_{fat})[/tex]

In such a way, solving for the final temperature, we obtain:

[tex]T_F=\frac{m_{Ag}C_{Ag}T_{Ag}+m_{fat}C_{fat}T_{fat}}{m_{Ag}C_{Ag}+m_{fat}C_{fat}}}[/tex]

Then, we plug in the given data to obtain:

[tex]T_F=\frac{14.16g*0.2165J/g\°C*133.5\°C+250g*3.94J/g\°C*17.20\°C}{14.16g*0.2165J/g\°C+250g*3.94J/g\°C} \\\\T_F=17.56\°C[/tex]

Answer:

6C2H2(g) + 16H2O(g) + 3CO2(g) ------> 6Ca(OH)2(s) +  5CH2CHCO2H(g)

Explanation:

The reaction has the first step as the reaction of calcium carbide with water to yield acetylene and calcium hydroxide as follows;

6CaC2(s) + 12H2O(g) -----> 6C2H2(g) + 6Ca(OH)2(s)

In the second step, acetylene, carbon dioxide and water react to form acrylic acid as follows;

6C2H2(g) + 4H2O(g) + 3CO2(g) ------>  5CH2CHCO2H(g)

The overall reaction equation is as follows;

6C2H2(g) + 16H2O(g) + 3CO2(g) ------> 6Ca(OH)2(s) +  5CH2CHCO2H(g)
