 <span>There is approximately 15 degrees of Longitude for each tine zone. 24 x 15 = 360. 

Latitude does not affect time, however it does affect what time the Sun will rise & set.
hope this help!</span>

Zinaida [17]

Answer:

2.9 g

Explanation:

There is some info missing. I think this is the original question.

<em>Ammonium perchlorate is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas, chlorine gas, oxygen gas, water, and a great deal of energy. </em>

<em>What mass of water is produced by the reaction of </em><em>9.6 g</em><em> of ammonium perchlorate?</em>

<em />

Step 1: Given data

Mass of ammonium perchlorate: 9.6 g

Step 2: Write the balanced equation

2 NH₄ClO₄(s) → N₂(g) + Cl₂(g) + 2 O₂(g) + 4 H₂O(l)

Step 3: Calculate the moles corresponding to 9.6 g of ammonium perchlorate

The molar mass of ammonium perchlorate is 117.49 g/mol.

9.6 g \times \frac{1mol}{117.49 g} = 0.082mol

Step 4: Calculate the moles of water formed from 0.082 moles of ammonium perchlorate

The molar ratio of NH₄ClO₄ to H₂O is 2:4. The moles of water formed are 4/2 × 0.082 mol = 0.16 mol

Step 5: Calculate the mass corresponding to 0.16 moles of water

The molar mass of water is 18.02 g/mol.

0.16 mol \times \frac{18.02g}{mol} = 2.9 g

A student states that the graduated cylinder contains 150 mL of water his statement is
Gre4nikov [31]

The correct answer is B. An observation

Explanation:

An observation is defined as a statement or conclusion you made after observing or measuring a phenomenon, this includes statements based on precise instruments. For example, if you conclude a plant grows 2 inches every month by measuring the plant during this time, this is classified as an observation. The conclusion of the student is also an observation because he concludes this after analyzing the volume of the water in the cylinder through the lines in the graduated cylinder, considering the water is just in the middle of 100 mL and 200 mL which indicates there are 150 mL of water.

The volume of a diamond is found to be 2.8 ml. what is the mass of the diamond in carats?
Helen [10]

Answer:

49.14 carat.

Explanation:

From the question given above, we obtained the following data:

Volume of diamond = 2.8 mL

Mass of diamond (in carat) =.?

Next, we shall determine the mass of diamond in grams (g). This can be obtained as follow:

Volume of diamond = 2.8 mL

Density of diamond = 3.51 g/mL

Mass of diamond ( in grams) =?

Density = mass /volume

3.51 = mass /2.8

Cross multiply

Mass of diamond (in g) = 3.51 × 2.8

Mass of diamond (in g) = 9.828 g

Finally, we shall Convert 9.828 g to carat. This can be obtained as follow:

1 g = 5 carat

Therefore,

9.828 g = 9.828 g /1 g × 5 carat

9.828 g = 49.14 carat.

Therefore, the mass of the diamond in carat is 49.14 carat.
