Answer:
has 17 electrons
Explanation:
Chlorine is a halogen that belongs to the 17th group on the periodic table. Chlorine has an atomic number of 17. The atomic number of elements is used in placing and locating elements on the periodic table. In fact, the periodic arrangements of elements is as a result of their atomic numbers.
The atomic number is the number of protons in an atom. This number is the same as the number of electrons in a neutral atom that has not gained or lost any electron.
It is correct to say chlorine has 17 electrons and they occupy 3 electronic shells.
Answer: B(water)
Explanation:
Photosystem II uses energy from light to extract electron from water molecule to fill the hole left as the energized electron passes up the chain.When the electrons are removed from the water molecules,the water molecule breaks down into oxygen gas,which bubbles away, and hydrogen ions,which are used to power ATP synthesis.
Answer:
The answer to your question is: 1.61 l
Explanation:
Data
Volume = ?
Molarity = 4.5 M
# of moles = 7.25 mol
Molarity = # of moles / volume
Volume = # of moles / molarity
Process
Volume = 7.25 moles / 4.5
Volume = 1.61 liters
First, write a balanced equation
FeBr3 + 3AgNO3 -> 3AgBr + Fe(NO3)3
Find the number of moles of FeBr3 we started with to find the number of moles of AfBr we end up with (we need to build a ratio)
3.96g FeBr3 / 295.55 g/mol * 3 mol AgBr / 1 mol FeBr3 * 187.77 g /mol = 7.55 g AgBr
Answer:
Explanation:
1. Increasing the concentrations of reactants in a chemical reaction would affect a reaction positively by increasing the number of collisions within a particular period which in turn increases the rate of reaction.
2. The molecules gains energy,which enable them to move faster and collide with the right energy for a reaction to take place.
3. The average kinetic motion of molecules in a solution can be measured by measuring the temperature. Temperature is a measure of the average kinetic energy of molecules in a solution.
