Answer: 0.174 g
Explanation:
First of all understand that charge on an atom like here 2+ will not vary molar mass. because ions are formed by loss or gain of electrons and electrons do not contribute to the mass of an atom or ion. so losing or gaining electron doesnt create any difference.
molar mass of Fe, i.e. mass of 1 mole of Fe is 56 g. So, mass of 1 mole of Fe2+ will also be 56 g.
given is 0.003109 moles of Fe2+,
Use maths,
1 mole of Fe2+ weighs 56 g
So, 0.003109 moles will weigh = (56 g / 1 mol ) x 0.003109 = 0.174 g.
Answer: Wash your hand Througly
Explanation:The things you handle in a lab can be dangerous and seeing as though it is a common habit to touch your skin and your face the things handled can make you and others sick. Washing your hands after every science lab session is essential to lab and outside lab safety.
The false statement is that the reaction of 17 g of NH3 will produce 27 g of water. (Option D)
<h3>What is a balanced reaction equation?</h3>
A balanced reaction equation is one in which the number of atoms of each element on the right hand side of the equation is equal to the number of atoms of the same element on the left and side of the reaction equation.
The equation of the reaction is 4 NH3 + 5 O2 → 4 NO + 6 H₂O. The number of atoms of each element on both sides are equal.
Hence, the statement that is false from the reaction equation is; "the reaction of 17 g of NH3 will produce 27 g of water".

Answer:
1. Kelvin
Explanation:
The standard temperature for scientific report is the kelvin.
According to the SI unit definition, temperatures should reported in Kelvin.
- On the kelvin scale, the freezing point of water is 273k
- The melting point of water is 373k
- The kelvin is widely accepted in scientific climes.
- It is possible to convert from this scale to another.
