7) The fuel used to power the booster rockets on the space shuttle is a mixture of aluminum metal and ammonium perchlorate. The

following balanced equation represents the reaction of these two ingredients: 3Al + 3NH4ClO4 → Al2O3 + AlCl3 + 3NO + 6H2O a. If 1.50 × 105 g of Al react, what mass of NH4ClO4, in grams, is required?

TLDR: 6.53x10^5 g NH4ClO4

The stoichiometric coefficients (the numbers in front of the reactants and products) show that Aluminum and Ammonium Perchlorate are consumed at the exact same rate throughout the reaction: 3 parts of one to 3 parts of another.

1.5x10^5 grams of Aluminum, considering that the formula weight of Aluminum is 26.98 g/mol, is equal to 5,559.7 moles of Aluminum. This means that 5,559.7 moles of Ammonium Perchlorate are required to run the reaction to completion.

The formula weight of Ammonium Perchlorate is 117.49 grams a mole, and multiplying it by 5,559.7 moles to react to completion means that 6.53x10^5 grams of Ammonium Perchlorate is required for the reaction.

Which phrase describes non-foliated rocks? only one!
irinina [24]

Answer:

include quartzite and marble

Explanation:

non-foliated rocks are

1. metamorphic rocks

2. they are formed in the surrounding of igneous rocks

3. The environmental condition of formation of non-foliated rocks are that temperature is very high

4. pressure is very low but equal from all direction on igneous rocks

5. The constituent material crystalizes to form large rocks in which atoms are tightly and closely packed. Due to this density of these rocks are also higher.

Example of such rocks are

Quartzite : Its  constituent material are mineral quartz and metamorphosed sandstone

Marble : its constituent material are mineral calcite; metamorphosed limestone

Hence, include quartzite and marble is the correct choice.

Which of the substances in the chart has the least density?
3241004551 [841]
Answer:
            Option-D (Piece of Wood) is the correct answer.

Explanation:
                   Density is related to mass and volume as,

                             Density  =  Mass / Volume
For Wood,
                             Density  =  42.5 / 50

                             Density  =  0.85

You can calculate remaining densities by yourself. Among all the density of Piece of Wood is the least.
