Answer: Different forms of chlorophyll
Explanation:
Depending on the significance the of the chlorophyll it’s function is to absorb light, which excites electrons in the chlorophyll.
Answer:
453.6 g
Explanation:
The following data were obtained from the question:
Mole of Ag = 4.2 moles
Weight (in grams) of Ag =?
Thus, we can obtain the weight in grams of Ag by doing the following:
Mole of Ag = 4.2 moles
Molar mass of Ag = 108 g/mol
Mass of Ag =.?
Mole = mass /Molar mass
4.2 = mass of Ag /108
Cross multiply
Mass of Ag = 4.2 × 108
Mass of Ag = 453.6 g
Thus, the weight (in grams) of 4.2 moles of Ag is 453.6 g
Wavespeed = frequency x wavelength.
Wavespeed = 0.09 x 10
Wavespeed = 0.9 ms^-1
Answer:
2HBr + Pb(NO₃)₂ → PbBr₂ + 2HNO₃
Explanation:
Hydrobromic acid (HBr), reacts with lead (II) nitrate (Pb(NO₃)₂) producing Lead(II) bromide (PbBr₂) and nitric acid (HNO₃). The reaction is:
HBr + Pb(NO₃)₂ → PbBr₂ + HNO₃
This reaction is unbalanced. You can see in products 2 Bromides but in reactants just 1. And in reactants 2 NO₃ but as product just 1. Thus, you can balance the equation, thus:
<em>2HBr + Pb(NO₃)₂ → PbBr₂ + 2HNO₃</em>
And this equation is the answer of your question!
