Club soda so A, you just gotta match the color that it says for it to the chart and it’ll show the identity the ph which is four I believe It said
Answer:
Isotopes are atoms of the same element with the same number of protons but different number of neutrons.
Hope this helps.
According to the balanced equation of the reaction:
H2X (aq) +2 NaOH (aq) → Na2X (aq) + 2H2O(l)
First, we have to get the no. of moles of H2X:
no.of moles of H2X = weight / molar mass
when we have the H2X weight = 0.1873 g & the molar mass H2X = 85 g/mol
So by substitution:
∴ no.of moles of H2X = 0.1873 /85
= 0.0022 mol
-then, we need to get no.of moles of NaOH:
from the balanced equation, we can see that 1 mol H2X = 2 mol NaOH
∴ no.of moles of NaOH = no.of moles of H2X *2
= 0.0022 * 2 = 0.0044 mol
So we can get the volume per litre from this formula:
M (NaOH) = no.of moles NaOH / Volume L
So by substitution:
0.1052 = 0.0044 / Volume L
∴Volume = 0.042 L *1000 = 42 mL
Answer:
Explanation:
Florida is much closer to the sun as compared to New York and seems to be much warmer as compared to New York even in winter and summer because of the latitude.
Answer:
diffusion
Explanation:
Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration in response to a concentration gradient. A concentration gradient simply means a difference in concentration.
Diffusion occurs in solids,liquids and gases. Diffusion is fastest in gases and slowest in solids. Diffusion of solid particles may take very many years while diffusion of gases takes a few milliseconds depending on the mass of the gas.
In materials, atoms and molecules also move from one part of the material to another. This is also refereed to as diffusion.
