The atomic number actually represents the number of
electrons in the atom. So when the atomic number is 24 and the actual number of
electron is only 22, so this means that there is a deficit of 2 electrons.
Hence the charge must be positive 2.
Answer:
2+
Answer: I'm guessing but I think this is the answer and also what I put in mine sorry if wrong
Explanation: I think it's "B.- Slightly Acidic" srry if it's too late-
A.true (<span>Yes we are! Though the amount is so small that it really has no major effect on us. This radiation does cause some genetic mutations if it encounters the DNA of the cell, but there are many other possible sources of mutations that make it hard to clearly blame a given mutation on radiation at the levels due to ordinary daily exposure.)</span>
Answer:
Explanation
Let, Wavelength = W,
Given, frequency (f) = 50 Hz, wave velocity (V) = 342 m/s
We know, V = f × W
=> 342 = 50 × W
=> W = 342/50 metre
=> W = 6.84 metre
Answer:
Mass of ethanol obtained is 260.682 grams.
Volume of the ethanol obtained is 0.3304 L.
Explanation:
Moles of glucose =
According to the reaction, 1 mol of gluocse gives 2 moles of ethanol.
Then 2.833 moles of glucose will give :
Mass of 5.667 moles of an ethanol :
5.667 mol × 46 g/mol = 260.682 g
Volume of ethanol = V
Density of the ethanol = 0.789 g/mL
Mass of ethanol obtained is 260.682 grams.
Volume of the ethanol obtained is 0.3304 L.
