Answer:
41 inches
Explanation:
There is 12 inches in 1 foot so times 12 and 3. Thats 36 so now do 36 + 5 that =41.
Nutrients
All microorganisms need food. The food sources can vary, but the organisms primarily extract carbon and nitrogen from substances such as proteins, fats and carbohydrates. Some microorganisms seek out and absorb such particles. Others may perform chemical reactions with surrounding elements such as carbon dioxide to gain what they need, while still others can produce their own simple sugars through photosynthesis similar to plants. Nitrogen, which is used to synthesize proteins, can be taken from the surrounding atmosphere or from other organic matter.
Temperature
In general, the higher the temperature, the more easily microorganisms can grow up to a certain point. Very high and very low temperatures both obstruct the enzyme processes microorganisms depend on to survive, but individual species of microorganisms have grown to prefer different levels of temperature. Scientists usually divide them into three different groups: psychrophiles, mesophiles and thermophiles. Psychrophiles prefer temperatures from 0 to 5 degrees Celsius; mesophiles like it in the middle, 20-45 degrees Celsius; and thermophiles like it hot, thriving in temperatures around or above 55 degrees.
pH Levels
Microorganisms also prefer a certain pH level in the substance or environment in which they grow--that is, they prefer to have particular acidic qualities in their surroundings. Most microorganisms, including most human pathogens, are neutriphils, organisms that prefer a neutral pH level. Some like high pH levels, but most often, if conditions are too acidic, then the organism's enzymes break down.
Moisture
The free flow of water is vital to microorganisms for their cells to exchange materials and for their metabolic processes. All microorganisms require some level of water, but a few can survive in low-moisture conditions by conserving all the water they find and by staying in a moisture-rich environment. As a general rule, though, the more moisture, the more microorganisms there will be found.
Elements Present
:
Option (c) is the correct answer.
Explanation:
It is known that when we move down a group then there is increase in size of atom. This is because there occurs increase in number of shells in the atom.
Also, when an atom loses electrons then it acquires a positive charge and size of the atom decreases. On the other hand, when an atom gain electrons then it acquires a negative charge and size of the atom increases.
Since, both Rb and K are same group elements and Rb has larger atomic size than K.
Hence, we can conclude that out of the given options K^{+}
+ has the smallest size.
<h3>
Answer:</h3>
1.02 moles
<h3>
Explanation:</h3>
<u>We are given;</u>
N₂O₅ + H₂O → 2HNO₃
- Moles of N₂O₅ is 0.51 moles
We are required to determine the number of moles of HNO₃ produced.
First, we need to identify the mole ratio of N₂O₅ to HNO₃
- From the equation 1 mole of N₂O₅ reacts to produce 2 moles of HNO₃
- Therefore, the mole ratio of N₂O₅ to HNO₃ is 1 : 2
Second; we can determine the moles of HNO₃
Moles of HNO₃ = Moles of N₂O₅ × 2
= 0.51 Moles × 2
= 1.02 moles
Thus, the number of moles of HNO₃ that will be produced is 1.02 moles
Answer:
A positive ion has more protons than electrons and a negative ion has more electron ions
So the answer is
A positive ion has less electrons and a negative ion has more electrons
