Answer:
1,300,000,000,000
Explanation:
1.3 x 10^12
We want to convert this from scientific notation.
Tip: in scientific notation the exponent tells you how many place you move the decimal point over. If the exponent is negative you move the decimal point to the left. Ex. For, 4.1 x 10^-8, we would move the decimal point over 8 times to the left to get .00000041. When the exponent is positive we move over to the right. Ex. For, 7.6 x 10^7 we would move the decimal point over 7 times to the right to get 76,000,000
So to convert 1.3 x 10^12 we simply move over the decimal point over 12 times to the right.
1.3 x 10^12 ------> 1,300,000,000,000
Our answer is 1,300,000,000,000
divide 5 hours 20 mins by 4,000
and ur answer is
320 mins/4000km
so
0.08
hope this helps
sorry if its wrong
Answer:
A
Explanation:
Waxing means getting bigger.
Waning is.. you guessed it... the exact opposite.
The mass isnt relevant
520 - 120 = 400
400 / 8 = 50

Single Replacement & Decomposition
<h3>Further explanation</h3>
Given
Two chemical reactions
1. Cl2 + 2NaBr ⇒2NaCl + Br2
2. 2NaCl ⇒2Na + Cl2
Required
Type of reaction
Solution
Equation 1 : A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
General formula :
A + BC ⇒ AC + B
Equation 2 : the decomposition reaction of a compound into its constituent elements or compounds
General formula :
AB ⇒ A + B
