John traveled on a motorbike a distance of 1,500 meters north to get to the nearest shopping center. He then turned back south a

ivolga24 [154]

Answer:

50 Meters North

Explanation:

Displacement is the distance/direction from the start point to

the ending point, regardless of which route you took from the start to the end.

So, you would simply subtract:

1,500 meters North- 1,450 meters South= 50 meters North

Ammonium perchlorate (NH,CIO) is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen

meriva

<u>Answer:</u> The mass of oxygen gas produced is 2.4 grams

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

Given mass of ammonium perchlorate = 8.84 g

Molar mass of ammonium perchlorate = 117.5 g/mol

Putting values in equation 1, we get:

$\text{Moles of ammonium perchlorate}=\frac{8.84g}{117.5g/mol}=0.0752mol$

The chemical equation for the decomposition of ammonium perchlorate follows:

$2NH_4ClO_4\rightarrow N_2+Cl_2+2O_2+4H_2O$

By Stoichiometry of the reaction:

2 moles of ammonium perchlorate produces 2 moles of oxygen gas.

So, 0.0752 moles of ammonium perchlorate will produce = $\frac{2}{2}\times 0.0752=0.0752mol$ of oxygen gas

Now, calculating the mass of oxygen gas from equation 1, we get:

Molar mass of oxygen gas = 32 g/mol

Moles of oxygen gas = 0.0752 moles

Putting values in equation 1, we get:

$0.0752mol=\frac{\text{Mass of oxygen gas}}{32g/mol}\\\\\text{Mass of oxygen gas}=(0.0752mol\times 32g/mol)=2.4g$

Hence, the mass of oxygen gas produced is 2.4 grams

In the laboratory you dilute 2.49 ml of a concentrated 6.00 m hydrochloric acid solution to a total volume of 50.0 ml. what is t

Marizza181 [45]

Equation: M1V1 = M2V2

Where M = concentration & V = volume

Step 1: Write down what is given and what you are trying to find

Given: M1 = 6.00M, V1 = 2.49mL, and V2 = 50.0mL
Find: M2

Step 2: Plug in the values into the equation

M1V1 = M2V2
(6.00M)(2.49mL) = (M2)(50.0mL)

Step 3: Isolate the variable (Divide both sides by 50.0mL so M2 is by itself)

(6.00M)(2.49mL) / (50.0mL) = M2

Answer: M2 = 0.30M

Magnesium has three naturally occurring isotopes with masses of 23.99, 24.99, and 25.98 amu and natural abundances of 78.99%, 10

Darya [45]

Atomic mass of magnesium = (23.99 x 78.99%) + (24.99 x 10.00%) + (25.98 x 11.01%)
= 24.31 g/mol
