<span>2Al + 3Br2 -------------> 2AlBr3

</span>3 g Al = 0.11 mol Al. 

<span>6 g Br2 = 0.0375 mole bromine (it is diatomic). </span>

<span>moles of aluminium will take part in reaction = 0.0375 X (2/3) = 0.025. </span>

<span>Gram-mole of AlBr3 will be produced = 0.025 mole = 6.6682 g. 
</span>moles of Al left = 0.11 - 0.025 = 0.086<span>


</span>

The chemical equation shown represents photosynthesis.
nordsb [41]

Answer:

C

Explanation:

Photosynthesis is usually represented by the equation Carbon dioxide + water + light --> glucose + oxygen.

Therefore, <u>A substance is water</u> and <u>B is glucose</u>

A is incorrect because it's talking about glucose

B is incorrect because it's talking about chlorophyll, the important pigment in photosynthesis

D is incorrect because it combines to form oxygen, not hydrogen

Lead has a density of 11.3 g/cm3. what is the volume of a 15.1 g block of lead?
Crank
Hey there:

density = 11.3 g/cm³

mass = 15,1 g

Therefore: 

D = m / V

11.3 = 15.1 / V

V = 15.1 / 11.3

V = 1.336 cm³
