What numbers should be added to the blanks to balance this chemical equation? ___F2 + __ H20 --------> ___OF2 + ___HF A) 2,2,1,2
B)2,1,1,2
C)3,2,1,4
D)1,2,2,1
Answers
The numbers to be added to the blanks to balance this chemical equation are 2, 1 , 1 and 2
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Thus in the reactants, there are 2 atoms of hydrogen , 1 atom of oxygen and 4 atoms of flourine.Thus there will be atoms of hydrogen , 1 atom of oxygen and 4 atoms of flourine in the product as well.

Answer:
It is all of the above.
Explanation:
The Heliocentric theory was indeed rejected by many people. Most people were religious and the church believed in the Geocentric theory.
Galileo did indeed support the the theory by using his telescope and observed the moons of Jupiter and saw how they all orbited Jupiter which contributed to the Heliocentric theory.
The Heliocentric theory did believe that the Earth rotated around our sun.
butan-1-amine + CH3I -->
Answers
Here we have to get the product between the reaction of butane-1-amine with methyl iodide (CH₃I).
The reaction between 1 mole of butan-1-amine and 1 mole of methyl iodide produces Methyl-butamine which is a secondary amine.
However, In presence of 2 moles of methyl iodide the reaction proceed to N, N-di-methylbutamine. The reaction is shown in the figure.
This is one of the effective reaction method to generate secondary and tertiary amine from primary amine.
The primary amine reacts with alkyl iodide to form secondary to tertiary amine. The final product depends upon the quantity of the alkyl iodide present in the reaction.
