The amount of heat (in KJ) released when 3.5 moles of CH₄ react is 3115 KJ

<h3>Balanced equation</h3>

CH₄ + 2O₂ -> CO₂ + 2H₂O ΔH = 890 KJ

From the balanced equation above,

1 mole of CH₄ reacted to release 890 KJ of heat energy.

<h3>How to determine the heat energy released by 3.5 moles of CH₄</h3>

From the balanced equation above,

1 mole of CH₄ reacted to release 890 KJ of heat energy

Therefore,

3.5 moles of CH₄ will react ro release = 3.5 × 890 = 3115 KJ of heat energy

Thus, 3115 KJ of heat energy were released from the reaction

A cab charges $1.75 for the flat fee and $0.25 for each mile. write and solve an inequality to determine how many miles eddie ca
ad-work [718]
The answer is <span>a. $1.75 + $0.25x ≤ $15; x ≤ 53 miles
</span>
x - the number of miles
C - the cab charge

<span>A cab charges $1.75 for the flat fee and $0.25 for each mile:  C = 1.75 + 0.25x.
</span><span>Eddie has $15 to spend. So, he cannot spend more than 15 on the cab and the maximum amount he can spend is 15. Therefore:
</span>1.75 + 0.25x ≤ 15

Now, let's solve it:
0.25x ≤ 15 - 1.75
0.25x ≤ 13.25
x ≤ 13.25 / 0.25
x ≤ 53

Help Plzzz i cant find the answer
Kryger [21]
To solve this, you need to know slope-intercept form;  
y=mx+b  
Where mx is the slope and b is the y-intercept form.  
Now, looking at the values you have been provided, you can just plug them into the formula.  
y= \frac{2}{3}x -2

Find me the LCM of 11,7 and show me how u do it
VashaNatasha [74]

Answer:77

Step-by-step explanation:

Least Common Multiple of 7 and 11 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).

We need to calculate greatest common factor 7 and 11, than apply into the LCM equation.

GCF(7,11) = 1

LCM(7,11) = ( 7 × 11) / 1

LCM(7,11) = 77 / 1

LCM(7,11) = 77

Least Common Multiple (LCM) of 7 and 11 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 7 and 11. First we will calculate the prime factors of 7 and 11.

Prime Factorization of 7

Prime factors of 7 are 7. Prime factorization of 7 in exponential form is:

7 = 71

Prime Factorization of 11

Prime factors of 11 are 11. Prime factorization of 11 in exponential form is:

11 = 111

Now multiplying the highest exponent prime factors to calculate the LCM of 7 and 11.

LCM(7,11) = 71 × 111

LCM(7,11) = 77
