This reaction shows the complete combustion of octane, C8H18, a component of gasoline. How many moles of O2 are needed to burn 2
ANTONII [103]
How you're going to answer this question is by doing a mole t - chart first you're going to put 2.40 mol of C8H18 opposite of the mol then you're going to find o2 which 256 on the bottom then multiply across to get the answer.

Hope this help, message me if you need more help

You deposit $1000 into a savings plan at the end of each
Aloiza [94]

Answer:

FV = $3506.112

Interest = $506.112

Explanation:

We are given;

Annual deposit; A = $1000

Interest rate; i = 8% = 0.08

Number of years; n = 3

The value of the annuity after 3 years will be gotten from the formula;

FV = A[((1 + i)ⁿ - 1)/i](1 + i)

FV = 1000(((1 + 0.08)³ - 1)/0.08)(1 + 0.08)

FV = 1000(1.08⁴ - 1.08)/0.08

FV = $3506.112

Since you deposited $1000 each year, then after 3 years, total deposited = 3 × 1000 = $3000

Since FV = $3506.112, then interest = $3506.112 - $3000

Interest = $506.112

The Prandtl number, Pr, is a dimensionless group important in heat transfer. It is defined as Pr - Cp*mu/k where Cp is the heat
algol [13]

Answer:

The Prandtl number for this example is 14,553.

Explanation:

The Prandlt number is defined as:

Pr=\frac{C_{p}*\mu}{k}

To compute the Prandlt number for this case, is best if we use the same units in every term of the formula.

\mu=1896 \frac{lbm}{ft*h}*\frac{1000 g}{2.205 lbm}*\frac{3.281 ft}{1 m}*\frac{1h}{3600s}  =7938 \frac{g}{m*s}

Now that we have coherent units, we can calculate Pr

Pr=\frac{C_{p}*\mu}{k}=0.66*7938/0.36=14553

Does the bowling ball have more potential energy or kinetic energy just before it hits the ground? Why?
AnnZ [28]

Answer:

Equal

Explanation:

When the bowling ball is first dropped, it has a maximum potential energy but minimum kinetic energy.  The height is max, so the potential energy will be greatest.  Velocity is 0, so kinetic energy will be 0.
