Answer: Mass of produced in this reaction was 6.56 grams
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.
Mass or reactants = Mass of + mass of = 16.00 + 64.80 = 80.80 g
Mass of products = mass of aqueous solution + mass of + = 74.24 + x g
Mass or reactants = Mass of products
80.80 g = 74.24 + x g
x = 6.56 g
Thus mass of produced in this reaction was 6.56 grams
a large amount of mass can produce a large amount of energy
Explanation:
The mass energy relationship E = mc² suggests that a large amount of mass can produce an equally large amount of energy.
- Nuclear fission is a radioactive decay process in a large atomic nuclei disintegrates into smaller ones until it is stable.
- Most nuclear reactions produce a lot of energy.
- The energy originates from the conversion of some of the mass into energy.
- The mass usually decreases i.e mass deficit accompanies nuclear reactions.
- The lost mass is converted to energy.
- From the equation derived by Einstein, we see that mass and energy are equivalent.
- a large amount of mass can produce a large amount of energy.

An electromagent is being shown. Because the picture is showing how to put the lightnulb in and where it is
Answer:
here you go
Explanation:
Halogens are very electronegative. This means that inductively they are electron withdrawing. However, because of their ability to donate a lone pair of electrons in resonance forms, they are activators and ortho/para directing. Electron withdrawing groups are meta directors and they are deactivators.
solution:
First we calculate the number of mole of gas as follows:
PV = n RT
Here temperature; T= 100°C or 373 K
n = PV/ RT
= 4.78 atm * 3.82 L / 0.0821 L ∙ atm / mol ∙ K * 373 K
= 0.596 Moles
Now determine the molar mass of gas as follows:
Number of moles = amount in g/ molar mass
Molar mass = 19.08 grams / 0.596 Moles
= 32.013 g/ mole
This the molar mass of O2 hence the gas is oxygen
