We need more information to help please provide me with more information then @me when you do . ill be glad to help!
Answer:
1.Our results indicate that, at higher biodiversity, the impact of acidification on otherwise highly vulnerable key organisms can be reduced by 50 to >90%, depending on the species
2.Positive attitude is sometimes all it takes to turn a bad situation around. On the other side, a bad attitude can take a problem and quickly make it worse. Helps You Make Good Decisions – Anger clouds your judgement. When you let yourself get upset, you impact your ability to make good decisions.
Answer:
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
Law of multiple proportion:
When two elements combine to form two or more compounds with different proportions, the weight of on element that combine with other elements in fixed proportion is in the ratio of small whole number.
For example:
Consider the example of carbon dioxide and carbon monoxide.
CO and CO₂
we are given with 1 g carbon on both case while 1.3 g oxygen for carbon monoxide and 2.6 for carbon dioxide. It means the ratio of oxygen is 1:2.
There is 1.3 g of oxygen in carbon monoxide for one g of carbon while in case of carbon dioxide there is 2.6 g of oxygen for one gram of carbon.
We need to use the effusion formula. I have attached a picture of what this formula looks like because it is a bit hard to type.
effusion formula---> Rate 1/ rate 2= √(M2/M1)
as the questions states, hydrogen gas rate is 4 times the rate of the other gas. so, let call gas 1 the unknown and gas 2 the hydrogen
Rate 1= 1
Rate 2= 4
M1=??
M2= 2 grams
now let's plug in the values and solve for the unknown
1/4 = √(2/x)
x= 32 grams
with the choices given, the gases are either O₂, N₂ or O₃.
O₂ is the one whose mass is 32 because oxygen atomic mass in the periodic table is 16 grams. since we have two oxygens, then 16 x 2= 32
the answer is "<span>
32 grams and oxygen "</span>
Answer:
A. in the cells of autotrophs
Explanation:
Photosynthesis takes place in the cells of autotrophs. Autotrophs are capable of manufacturing their own food by two major means which is by photosynthesis or by chemosynthesis.
- In photosynthesis green plants manufacture their foods using sunlight to synthesize energy rich compounds from carbon dioxide and water.
- The product is often times glucose and oxygen gas.
Heterotrophs on the other hand depends on the food manufactured by the autotrophs for their nourishment
