Answer:
be able to meet long term timber needs.
Explanation:
Forest Services has been indicated for a long time the exhaustion of timer in the United States. However, in the recent decade, this trend has shown a reverse. The creation of nuclear energy and other technological developments that bring about drastic changes in our way of life. Gradually, the forest has recovered its trees and plants, and it is anticipated that timber will be available to meet long-term wood needs.

Answer:
77%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
34/44 = 0.77
0.77 x 100 = 77%
1.7 liters of water will be produced.
Explanation:
The balanced chemical reaction is:
2H2+ 02⇒ 2H20
Considering the reaction to be at STP (P = 1atm, V= 22.4 L, T = 273.15 K)
the formula used is:
PV = nRT
Where P, R and T remains same only volume and number of moles are different so,
= 
observing the balanced reaction:
mole ratio is 2:2 i.e 1:1
so volume ratio will also be same
so 1.7 litres of water will be produced.
From the reaction it is seen that
1 mole hydrogen react with oxygen to give 1 mole of water at STP.
so, it is found that 1.7 liters of hydrogen gives 1.7 liters of water
