Answer:

2.9 g of water are produced by 9.6 g of ammonium perchlorate

Note: The question is incomplete. The complete question is given below:

Ammonium perchlorate (NH₄ClO₄) is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) , and a great deal of energy. What mass of water is produced by the reaction of 9.6 g of ammonium perchlorate? Be sure your answer has the correct number of significant digits.

Explanation:

The reaction of ammonium perchlorate (NH₄ClO₄) to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) is shown in the balanced chemical equation given below:

2 NH₄ClO₄ → N₂ + Cl₂ + 2 O₂ + 4 H₂O

From the equation, 2 moles of ammonium perchlorate produces 4 moles of water, i.e. mole ratio of NH₄ClO₄ to H₂O = 2 : 4 = 1 : 2

molar mass of ammonium perchlorate, NH₄ClO₄ = (14 + 4 * 1 + 35.5 +16 * 4) = 117.5

molar mass of water, H₂O = (2 * 1 + 16) = 18.0 g

mass of water produced = moles of ammonium perchlorate * 2 * molar mass of water

moles of perchlorate = mass / molar mass = 9.6/117.5

mass of water produced = 9.6/117.5 * 2 * 18.0 g = 2.94 g of water

Therefore, 2.9 g of water are produced by 9.6 g of ammonium perchlorate

In the following reaction, how many grams of nitroglycerin c3h5(no3)3 will decompose to give 25 grams of co2?4c3h5(no3)3(l) 12co

Korolek [52]

The balanced reaction that describes the decomposition of nitroglycerin to produce carbon dioxide, nitrogen, water and oxygen is expressed: 4c3h5(no3)3(l) = 12co2(g)+ 6n2(g) +10h2o(g) + o2(g). Hence for every 4 moles of nitroglycerin used, 12 moles of carbon dioxide is produced. When 25 grams of CO2 is produced, we convert this to mass and multiply by 4/12 and multiply again with the molar mass of nitroglycerin. The answer is 42.99 grams nitroglycerin.

Which sentence most accurately describes electrically charged objects?

ivolga24 [154]

Answer:

They are attracted to one other without coming into contact.

Explanation:

In conclusion, an electrically neutral object is an object that has a balance of protons and electrons. In contrast, a charged object has an imbalance of protons and electrons. The type of charge (positive or negative) is determined by whether the protons or the electrons are in excess

A solid has shape and volume?

tia_tia [17]

Answer:

A solid has a definite volume and shape, a liquid has a definite volume but no definite shape, and there is no definite volume or shape of a gas. Usually, the transition from solid to liquid does not change a substance's volume substantially.

Which of the following statements is true? A) If Q < K, it means the forward reaction will proceed to form more products. B)

GuDViN [60]

Hey there!:

If Q = K, it means the reaction is at equilibrium.

The correct statments are as follows:

A. If Q < K, it means the forward reaction will proceed to form more products.

B. If Q > K, it means the backward reaction will proceed to form more reactants.

The statement C is true.

Hope this helps!
