The balanced chemical equation for the reaction between barium hydroxide, Ba(OH)₂ and HNO₃ to produce barium nitrate, Ba(NO₃)₂ is

Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + 2H₂O

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

Ba(OH)₂ + HNO₃ —> Ba(NO₃)₂ + H₂O

There are 2 atoms of N on the right side and 1 atom on the left side. It can be balanced by writing 2 before HNO₃ as shown below:

Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + H₂O

There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balanced by writing 2 before H₂O as shown below

Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + 2H₂O

Now, the equation is balanced

Partial pressure of carbon dioxide is high in the pulmonary capillaries.

Explanation:

Answer:

D

Explanation:

At T 25 ° C (298 K) and P 1 atm are stated by RTP ⇒ Vm = 24.4 liters / mol

86.4 dm³ = 86.4 L = 86.4/24.4 = 3.54 mol

1 mole = 6.02.10²³ molecules

3.54 x 6.02.10²³ = 21.31 x 10²³ molecules

N = 21.31

Answer:

Approximately [tex]1.7\; {\rm L}[/tex].

Explanation:

Nitrogen [tex]{\rm N_{2}}\, (g)[/tex] reacts with hydrogen [tex]{\rm H_{2}}\, (g)[/tex] at a [tex]1:3[/tex] ratio to produce ammonia [tex]{\rm NH_3}\, (g)[/tex]:

[tex]{\rm N_{2}}\, (g) + 3\; {\rm H_{2}}\, (g) \to 2\; {\rm NH_{3}}\, (g)[/tex].

The ratio between the coefficient of [tex]{\rm N_{2}}\, (g)[/tex] and the coefficient of [tex]{\rm H_{2}}\, (g)[/tex] is:

[tex]\begin{aligned}\frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].

Under the ideal gas assumptions, the same ratio would apply to the volume of [tex]{\rm N_{2}}\, (g)[/tex] and [tex]{\rm H_{2}}\, (g)[/tex] in this reaction:

[tex]\begin{aligned}\frac{V({\rm N_{2}})}{V({\rm H_{2}})} = \frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].

[tex]\begin{aligned}V({\rm N_{2}})= \frac{1}{3}\, V({\rm H_{2}})\end{aligned}[/tex].

Given that [tex]V({\rm H_{2}}) = 5.0\; {\rm L}[/tex]:

[tex]\begin{aligned}V({\rm N_{2}}) &= \frac{1}{3}\, V({\rm H_{2}}) \\ &= \frac{1}{3}\times 5.0\; {\rm L} \\ &\approx 1.7\; {\rm L}\end{aligned}[/tex].

Answer:

160

Explanation:

p*v/t = constant

or

p1*v1/t1 = p2*v2/t2

pressure is not stated in question so we get rid of it on both sides

v1/t1 = v2/t2

we are finding temperature so we flip the entire equation

t1/v1 = t2/v2

200/5 = t2/4

4(200/5) = t2

=160

Answer:

Yes it is 160K as the first person said

Explanation:

Answer:

10.77

Explanation:

The relationship between pH and pOH is

pH + pOH = 14

Plugging in the pOH makes

pH + 3.23 = 14

And solving for pH by subtracting 3.23 on both sides

pH = 10.77

Based on the assumption that the reaction involves N and O to produce NO, if 25.0 g of NO are produced, the amount of N gas used would be 11.66 grams

From the equation of the reaction:

       N + O ---------> NO

Mole ratio of N to NO is 1:1

Mole of 25.0 g of NO = 25/30.01 = 0.833 moles

Equivalent mole of N = 0.833 moles

Mass of 0.833 moles N = 0.833 x 14 = 11.66 grams

The Levelized Cost of Energy of the solar plant is $0.60 per kWh.

Solar energy and wind energy can both easily be integrated into existing power grid systems.

The Levelized Cost of Energy is a measure of the average net present cost of electricity generation for a generating plant over its lifetime.

The Levelized Cost of Energy of the solar energy product is calculated as follows:

Total cost over 25 years = 995,000, + $175,000 × 25 = $5,370,000

Total energy production over 25 years = 89,500,000 kWh

Levelized Cost of Energy = $5,370,000/89,500,000 kWh

Levelized Cost of Energy = $0.60 per kWh

The Levelized cost of energy (LCOE) is the minimum amount of power that can be produced per dollar over the lifetime of a power-generating project.

For solar energy and wind energy, power from both energy sources can easily be integrated into existing power grid systems.

Work is said to be done when force moves a distance and the direction of motion is in the direction of applied force.

Work done is defined as the product of applied force and the distance which the applied force moves.

According to Newton's second law of motion the acceleration of a body is inversely to its mass ut directly proportional to the force and takes place in the direction of the applied force.

Therefore, work is done when force moves a distance and the direction of motion is in the direction of applied force.

The cell notation of the redox reaction between Cu and ClO₃⁻ is:

A voltaic cell or electrochemical cell is a device which produces electricity from chemical reactions occuring within the cell.

The reactions occuring in a voltaic cell are redox reactions.

Oxidation occurs at the anode while reduction occurs at the cathode.

In the given reaction between Cu and ClO₃⁻ as shown below:

Cu is oxidized as follows: 3 Cu (s) → 3 Cu²⁺
ClO₃⁻ is reduced as follows: ClO₃⁻ (aq) → Cl⁻ (aq)
