Answer: 3.41 mL
Explanation: Solution:
Use Combine gas law to solve this problem.
P1V1 / T1 = P2V2 / T2
First convert temperature to K
T1 = 47 °C + 273 = 320 K
T2= 107°C + 273 = 380 K
Derive to find V2:
V2 = P1 V1 T2 / T1 P2
Substitute the values:
V2= 1.03 atm x 2.20 mL x 380 K /
320 K x 0.789 atm
= 3.41 mL
Cancel out the units of atm and K so the remaining unit is in mL.
In a reaction with bromine, antimony will oxidize itself to +III oxidation state forming {antimony (III) bromide
Sb(s)+Br2(l)→SbBr3(s)
Balance the equation by balancing Bromine.
2Sb(s)+3Br2(l)→2SbBr3(s)
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products side. In other words, the mass of the elements and the charge on them are balanced on both sides of the reaction.
A chemical equation needs to be balanced because a chemical reaction is just a rearrangement of atoms of the given elements. The chemical equation needs to be balanced to follow the law of conservation of mass.

Answer: the electric charge
Explanation:
2.85 × 10^22. A diamond with a mass of 0.568 g contains
2.85 × 10^22 atoms C.
Diamond is a form of pure carbon.
a) Convert <em>grams of C to moles of C</em>
Moles of C = 0.568 g C × (1 mol C/12.01 g C) = 0.047 29 mol C
b) Convert <em>moles of C to atoms of C
</em>
Atoms of C = 0.047 29 mol C × (6.022 × 10^23 atoms C)/(1 mol C)
= 2.85 × 10^22 atoms C
