Answer:
Volcanic mountains form as lava oozes forth from cracks in the earth. The lava builds up around the area where the eruption occurred. Layers build upon layers and over a period of time, a volcanic mountain forms. There are several ways that volcanic mountains are formed. Shield volcanoes, which are very wide with a gentle slope, are formed by long periods of eruption with low-viscosity lava.
Explanation: Hoped this helped! :)
Oh we have just done this in biology recently... photolysis occurs where it splits apart water molecules to make electrons and hydrogen ions (the H+ is used to reduce NaDP later on) and also O₂ is made as a by product
basically this is the equation 2H₂O⇒4e⁻ + 4H⁺ where the electrons replace the lost ones in chlorophyll
hope this helped :)
Answer:
• The Na atom is formed when the Na+ ion gains an electron.
• A Na+ ion has 10 electrons and a Na atom has 11 electrons.
• A sodium atom has one more electron shell than a sodium ion.
• A Na+ ion is formed when a Na atom loses an electron
Explanation:
Volume of the stock solution is 
= ?
Initial concentration of ampicillin is 
= 100 mg/ml
Final volume (
) = 30 ml
Final concentration of ampicillin (
) = 25 mg/ml
Therefore, calculate the volume of given stock as follows.
= 
Now, putting the given values into the above formula as follows.
=
= 
= 7.5 ml
Now, we will calculate the volume of water added into it as follows.
Volume of water added = 
= 30 ml - 7.5 ml
= 22.5 ml
Thus, we can conclude that required solution is 22.5 ml of deionized water.
Answer:
The answer is
<h2>464 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of solution = 80 mL
density = 5.80 g/mL
The mass is
mass = 80 × 5.8
We have the final answer as
<h3>464 g</h3>
