1)What is the mass of Nitrogen in NH3? (use two decimal places)

Mathematics
1 answer:
Mars2501 [29]2 years ago
6 0

Answer:

1)  The Mass of Nitrogen in NH_3 is<u> 14.00 gm.</u>

2) The Mass of Hydrogen in NH_3 is<u> 3.00 gm.</u>

3<u>)</u>The Molar Mass of NH_3 is <u>17.00 gm.</u>

Step-by-step explanation:

Solving for Part 1.

In NH_3 that is Ammonia there is 1 atom of Nitrogen.

So the atomic mass of Nitrogen is same as the mass of Nitrogen in NH_3.

Atomic mass of Nitrogen = 14.00 gm

Hence The Mass of Nitrogen in NH_3 is<u> 14.00 gm.</u>

<u />

Solving for Part 2.

In NH_3  there are 3 atoms of Hydrogen.

Atomic mass of Hydrogen = 1.00 gm

So the mass of Hydrogen in  NH_3 is 3 times of its atomic mass.

Mass of Hydrogen = 3 × Atomic mass of Hydrogen

Mass\ of\ Hydrogen =3\times1.00=3.00\ gm

Hence The Mass of Hydrogen in NH_3 is<u> 3.00 gm.</u>

<u />

Solving for Part 3.

In NH_3  there is 1 atom Nitrogen and 3 atoms of Hydrogen.

So molar mass is the sum of mass of nitrogen and mass of Hydrogen in NH_3.

Molar mass of NH_3=Mass of Nitrogen+Mass of Hydrogen

Molar\ mass\ of\ NH_3=14.00+3.00=17.00\ gm

Hence The Molar Mass of NH_3 is <u>17.00 gm.</u>

2y ( x-y) +12=5x where x=3
tamaranim1 [39]

EXPLANATION

Given the expression 2y(x-y) +12=5x , plugging in x=3 into the expression,

2y(3-y) + 12 = 5*3

6y -2y^2 + 12 = 15

Rearranging terms:

-2y^2+6y+12=15

Now, we need to apply the quadratic equation:

\mathrm{For\: a\: quadratic\: equation\: of\: the\: form\: }ax^2+bx+c=0\mathrm{\: the\: solutions\: are\: }x_{1,\: 2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\mathrm{For\: }\quad a=-2,\: b=6,\: c=-3y_{1,2}=\frac{-6\pm\sqrt{6^2-4\left(-2\right)\left(-3\right)}}{2\left(-2\right)}

Multiplying terms:

y_{1,2}=\frac{-6\pm\sqrt[]{36-24}}{-4}

Subtracting numbers:

y_{1,2}=\frac{-6\pm\sqrt[]{12}}{-4}

Simplifying:

\mathrm{The\: solutions\: to\: the\: quadratic\: equation\: are\colon}y=\frac{3-\sqrt{3}}{2},\: y=\frac{3+\sqrt{3}}{2}

An object dropped from rest from the top of a tall building on Planet X falls a distance feet in the first t seconds. Find the a
ch4aika [34]

Complete Question:

An object dropped from rest from the top of a tall building on Planet X falls a distance d(t)=13t^2 feet in the first t seconds. Find the average rate of change of distance with respect to time as t changes from t1=2 to t2=10. This rate is known as the average velocity, or speed.

The average velocity as t changes from 2 to 10 seconds is _______ feet/sec?

Answer:

v = 156

Step-by-step explanation:

Given

d(t)=13t^2

Time Interval: (a,b)

a = 2

b = 10

Required

Determine the average rate of change (v)

This is calculated as thus:

v = \frac{d(b) - d(a)}{b - a}

Substitute values for b and a

v = \frac{d(10) - d(2)}{10 - 2}

v = \frac{d(10) - d(2)}{8}

Calculate d(10): Substitute 10 for t

d(t)=13t^2

d(10) = 13 * 10^2

d(10) = 13 * 100

d(10) = 1300

Calculate d(2): Substitute 2 for t

d(t)=13t^2

d(2) = 13 * 2^2

d(2) = 13 * 4

d(2) = 52

The equation v = \frac{d(10) - d(2)}{8} becomes

v = \frac{1300 - 52}{8}

v = \frac{1248}{8}

v = 156

Hence, the average rate of change is 156ft/s

Rachel says that when she ran 155 yards , she went farther than Beth , who only ran 327 feet . is Rachel correct
algol [13]
1 yard = 3 feet
Therefore Rachel ran 155*3 feet = 465 feet
465 > 327 therefore she is correct
