Answer:
there will a definite decrease in solute solution
Explanation:
acid reaction acting upon negative charge.
In one glucose you have
6 carbon atoms
12 hydrogen atoms
6 oxygen atoms
if you have 3 then you are going to multiply the atoms by 3. 6 times 3 is 18.
you have 18 OXYGEN MOLECULES
Answer:
UVC > UVB > microwaves
Explanation:
Let's consider the following radiations with their ranges of wavelengths (λ).
The energy of a photon (E) can be calculated using the Planck-Einstein's equation.
E = h . c . λ⁻¹
where,
h is the Planck's constant
c is the speed of light
As we can see, <u>the shorter the wavelength, the more energy the photon has</u>. The rank from greatest to least energy is UVC > UVB > microwaves.

Answer:
The limiting reactant is AlCl₃ and the excess reactant is NaOH.
Explanation:
- The balanced equation for the mentioned reaction is:
<em>3NaOH(aq) + AlCl₃(aq) → 3NaCl(aq) + Al(OH)₃(s)↓,</em>
It is clear that 3.0 moles of NaOH(aq) react with 1.0 mole of AlCl₃(aq) to produce 3.0 moles of NaCl(aq) and 1.0 mole of Al(OH)₃(s).
- Firstly, we need to calculate the no. of moles of (8.0 g) of NaOH and (4.0 g) of AlCl₃:
no. of moles of NaOH = mass/molar mass = (8.0 g)/(40.0 g/mol) = 0.2 mol.
no. of moles of AlCl₃ = mass/molar mass = (4.0 g)/(133.34 g/mol) = 0.03 mol.
- From stichiometry; NaOH reacts with AlCl₃ with (3: 1) molar ratio.
∴ 0.09 mol of NaOH (the remaining 1.1 mol is in excess) reacts completely with 0.03 mol of AlCl₃.
<em>the limiting reactant is AlCl₃ and the excess reactant is NaOH.</em>
