Tokyo, Japan is 8817.6 km from California. how many millimeters is this? answer in scientific notation.

vitfil [10]

Answer:

$d=8.817\times 10^9\ mm$

Explanation:

It is given that,

Japan is 8817.6 km from California. We need to convert this distance in millimeters.

We know the conversion from km to mm is as follows :

1 km = 1000000

To convert mm km to mm use the unitary method as follows :

8817.6 km = 8817.6 × 1000000

$d=8.817\times 10^9\ mm$

Hence, the distance between Japan and California $8.817\times 10^9\ mm$ .

Copper metal (Cu) reacts with silver nitrate (AgNO3) in aqueous solution to form Ag and Cu(NO3)2. An excess of AgNO3 is present.

aev [14]

we are given the reaction Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag. This means for every mole Cu used, there are 2 moles of Ag produced. In this case, given 31.75 g Cu, converting to moles through molar mass and using stoichiometric ratio and the molar mass of Ag, the mass Ag produced is 107.9 grams.
