When the equation Al + Br2 → AlBr3 is balanced, the coefficient for Br2 isSingle choice.

zheka24 [161]

Answer:

The answer should be 2 because to balance the equation you should have to change to equation to this; 2Al + 3Br2 => 2AlBr3, so that there is a total of 2 Aluminums and 6 Bromiums on either side of the equation.

2.998x10^8 m/s is how many kilometers per hour

Alex

1.079 x 10⁹ km/h

<h3>Further explanation</h3>

2.998 x 10⁸ m/s has been known as the speed of light.

Let us convert the unit m/s to km/hour.

Change in unit length:

If 1 km = 1,000 cm, then $\boxed{ \ 1 \ cm = 0.001 \ km \ } \rightarrow \boxed{ \ 1 \ cm = 10^{-3} \ km \ }$

Change in unit time:

If $\boxed{ \ 1 \ hour = 60 \ minutes = 3,600 \ seconds \ }$ , then $\boxed{ \ 1 \ second = \frac{1}{3,600} \ hours \ }$

The Process:

$\boxed{ \ 2.998 \times 10^8 \ \frac{m}{s} \times \frac{10^{-3} \ km}{1 \ m} \times \frac{1 \ s}{\frac{1}{3,600} \ hours} \ }$

$\boxed{ \ 2.998 \times 10^8 \times 10^{-3} \ km \times \frac{3,600}{hours} \ }$

$\boxed{ \ 10,792.8 \10 \times 10^5 \ \frac{km}{hour} \ }$

Remember, we must write the results in scientific notation, i.e.,

$\boxed{\ a \times 10^b \ } \rightarrow \boxed{ \ 1 \leq a < 10 \ } \rightarrow \boxed{ \ b \ must \ be \ an \ integer \ }$

Thus the result of unit conversion is

$\boxed{ \ \boxed{ \ 2.998 \times 10^8 \ m/s \ } \rightarrow \boxed{ \ 1.079 \times 10^9 \ km/h} \ }$
