Answer:
All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space.
Explanation:
Answer:
Percent yield = 91%
Explanation:
Given data:
Theoretical yield of SF₆ = 124.3 G
Actual yield of SF₆ = 113.7 g
Percent yield of SF₆ = ?
Solution:
Formula:
Percent yield = (actual yield / theoretical yield)× 100
By putting values,
Percent yield = (113.7 g/ 124.3 g) × 100
Percent yield = 0.91 × 100
Percent yield = 91%
Answer:
1.)calcium+hydrochloric acid -->calcium chloride +hydrogen
2.)Ca + 2HCl -->CaCl2 + H2
3.)3.55g
Explanation:
1.) pretty self explanatory
2.)Ca + HCl -->CaCl2 + H2
then balance
Ca + 2HCl -->CaCl2 + H2 (+2 infront of Hcl)
3.) take calcium and calcium chloride
Ca + CaCl2
then you need the relative atomic mass of both
Ca=40
CaCl2=71 (40+(35.5x2))
Ca=40 40/40=1 1x2=2g
Then repeat that exact equation for calcium chloride
CaCl2=71 71/40=1.775 1.775x3=3.55g
Weather is the temperature or climate over a short period of time.
