<span>Group 18: noble gases
This is a matter of memorizing the groups of the periodic table. The rightmost column is group 18 which is the noble gases: Helium, Neon, Argon, Krypton, Xenon, Radon. In general, the noble gases don't make chemical compounds. Although there have been some compounds made with the heavier noble gases (Krypton, Xenon, Radon).</span>
Glucose is the major example of monosacchrides
succrose is an example of disaccharide
and both starch and cellulose are examples of polysaccharides
hope that helps :)
Below are the choices that can be found from other sources:
<span>A) elements
B) ions
C) molecules
D) neutrons
the answer is ions.
</span>A Star<span> and hence our Sun, is an almost entirely ionized ball of </span>plasma<span>, consisting of electrons and ions, in which there is hardly any gas (neutral atoms). The movement of the </span>plasma<span> produces strong magnetic fields and corresponding electric currents.</span>
Answer:
P = 3.23 atm
Explanation:
Given data:
Number of moles of gas = 30 mol
Temperature = 120°C
Volume of gas = 300 L
Pressure of gas = ?
Solution:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
120+273.15 = 393.15 K
P × 300 L = 30 mol × 0.0821 atm.L/mol.K × 393.15 K
P = 968.33 atm. L /300 L
P = 3.23 atm
Answer: W + BgCz2 arrow WCz + Bg
2 W + BgCz2 arrow 2 WCz + Bg
Explanation:
Cz has 2 so you balcne the other side of WCz.
Since you Balcanes the Cz you changed the W and you Balcanes the other W on the left side.
