7. A cyclist starting from rest accelerates at a rate of 6 m/s until she reaches 30 m/s. How long does it take her to accelerate?

Explanation:

The given values are:

a= 6m/s²

u= 0 m/s

v = 30 m/s

t= ?

The formula is :

thus,

Balanced Chemical Equation

2FeBr3 + 3Ba(OH)2 → 2Fe(OH)3 + 3BaBr2

Explanation:

Reaction Information

Ferric Bromide + Barium Hydroxide = Iron(III) Hydroxide + Barium Bromide

Reaction Type

Double Displacement (Metathesis)

Reactants

Ferric Bromide - FeBr3

FeBr3

Molar Mass of Br3Fe Oxidation State of Br3Fe

Barium Hydroxide - Ba(OH)2

Caustic Baryta Barium Hydroxide Lime Ba(OH)2 Barium Dihydroxide Hydrate

Molar Mass of BaH2O2 Oxidation State of BaH2O2

Products

Iron(III) Hydroxide - Fe(OH)3

Ferric Hydroxide Ferric Oxide Yellow

Molar Mass of FeH3O3 Oxidation State of FeH3O3

Barium Bromide - BaBr2

Molar Mass of BaBr2 Oxidation State of BaBr2

FeBr3 + Ba(OH)2 = Fe(OH)3 + BaBr2

Instructions

To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.Ionic charges are not yet supported and will be ignored.Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.Compound states [like (s) (aq) or (g)] are not required.You can use parenthesis () or brackets []
