Muiltplying 2.5 x 10^10 by 3.5 x 10^-7
andrey2020 [161]

<u>Answer: </u>

The value of \left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right) is 8750

<u>Solution: </u>

\left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right)

\Rightarrow\left(2.5 \times 10^{10} \times 3.5 \times 10^{-7}\right)

\Rightarrow\left(2.5 \times 3.5 \times\left(10^{10} \times 10^{-7}\right)\right)

\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)

\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)

\Rightarrow(2.5 \times 3.5) \times 10^{3}

\Rightarrow 8.75 \times 10^{3}

\Rightarrow 8.75 \times 1000=8750

How many water molecules are produced when 5.2g O2 are reacted
gtnhenbr [62]

Answer:

Total number of water molecules produced after the reaction is 1.956×10^22 molecules of water.

Explanation:

By the reaction

H2+ 1/2 O2 → H2O

Moles of O2 = 5.2\32

⇒1 mole of O2 produce 1  mole of H2O

  1 mole O2 will produce 2 mole  of H2O

Therefore, 5.2\32 mole will produce {2}\times{\frac{5.2}\times{32}}

⇒ Molecules of H2O  will be

         {2}\times{\frac{5.2}{32}} = \frac{x}{{6.02}\times{10^23}}

= 1.956×10^22 moleculesof H2O.
