Answer:
375
Explanation:
Divide 250 by 500 which would give you .5. Then multiply .5 to 750 which would give you 375
Answer:
100 yard = 9144 centimeters
9144 / 3.2 = 2,8575 round off
= 2,858 paperclips
Explanation:

cuz carbon dioxide is greenhouse gasses
Answer : The balanced chemical equation is,

Explanation :
Rules for the balanced chemical equation in basic solution are :
- First we have to write into the two half-reactions.
- Now balance the main atoms in the reaction.
- Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
- If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
- If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion
at that side where the less number of hydrogen are present. - Now balance the charge.
The half reactions in the basic solution are :
Reduction :
......(1)
Oxidation :
.......(2)
Now multiply the equation (1) by 2 and then added both equation, we get the balanced redox reaction.
The balanced chemical equation in a basic solution will be,

1.7 km^2 already has two significant figures.
