Answer

This is the correct answer please give me 5-star and likes

Explanation:

If nutrients are added to an ecosystem, then the composition of the plant community at different stages of succession will also change because different species take advantage of different soil conditions.

What is produced during the replacement reaction if Ba(NO3)2 and Na2SO4?
Nadusha1986 [10]

Answer : Barium sulfate(BaSO_4) and Sodium nitrate(NaNO_3) are produced during replacement reaction.

Explanation :

Double-displacement reaction : It is a type of chemical reaction in which two reactants exchange ions to form two new compounds.

The Net balanced chemical reaction is ,

Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow BaSO_4(aq)+2NaNO_3(aq)

This is a double-displacement reaction.

In this reaction, barium nitrate react with the sodium sulfate to produce barium sulfate and sodium nitrate.

How does a balanced chemical equation satisfy the law of conservation of mass
ELEN [110]
Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. ... When an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced.

what is the molarity of a solution made by dissolving 18.5 grams of NaCL into enough water to reach 450.0ML​
ValentinkaMS [17]

Answer:

0.702M

Explanation:

Molarity of a solution, which refers to the molar concentration of that solution can be calculated thus;

Molarity = number of moles (n) ÷ volume (V)

Firstly, we convert 18.5 grams of NaCl to moles using the formula; mole = mass/molar mass

molar mass of NaCl = 23 + 35.5 = 58.5g/mol

mole = 18.5/58.5

mole = 0.32moles

Volume of water (V) = 450mL = 450/1000 = 0.450L

Molarity = n/V

Molarity = 0.32/0.450

Molarity = 0.702M

Given that Delta. G for the reaction below is –957. 9 kJ, what is Delta. Gf of H2O? 4NH3(g) 5O2(g) Right arrow. 4NO(g) 6H2O(g) D
vesna_86 [32]

ΔG for the formation of H₂O is -228.6 kJ.

<h3>How we calculate Gibb's free energy of the reaction?</h3>

Gibb's free energy of the reaction is calculated as:

ΔG = G for product - G for reactant

Given chemical reaction is:

4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(g)

In the question, given that:

ΔG for the reaction = -957. 9 kJ

ΔGf of NH₃ = -16. 66 kJ/mol

ΔGf of NO = 86. 71 kJ/mol

Equation for ΔG will be written as:

ΔG = (ΔGf of NO + ΔGf of H₂O) - (ΔGf of NH₃+ ΔGf of O₂)

ΔGf of O₂ = 0

-957. 9 = (4×86. 71 + 6×ΔGf of H₂O) - (4×-16. 66 + 5×ΔGf of O₂)

-957. 9 = 346.84 + 6ΔGf of H₂O + 66.64

ΔGf of H₂O = (-957. 9 - 346.84 - 66.64) / 6

ΔGf of H₂O = -228.56 kJ ≅ -228.6 kJ

Hence, option (1) is correct i.e. -228.6 kJ is the ΔGf of H₂O.
