Answer:
Explanation:
b is the most stable( noble gas ) since it has an octet valance shell and can't loses or gains any more of electrons
Answer:
1. not affected by a magnet 1 liquid
2. mostly space 2 solid
3. flows freely but particles still attract 3 proton
4. positively charged particles 4 gas
5. free to move in all space 5 alpha particles
6. negatively charged particles 6 atoms
7. atoms nearly fixed in space 7 gamma ray 8. helium nucleus 8 electron (beta)
Answer:
Both Options C and D are appropriate.
But I'd go with Option D since "Direct Air Capture" would eventually lead to "Ground Injection"
OPTION D.
Answer:
D. 34.5g
Explanation:
Using the following formula to calculate the mass of 1.5moles of sodium (Na);
Mole = mass/molar mass
Molar mass of Na = 23g/mol
mass = mole × molar mass
Mass of Na = 1.5mol × 23g/mol
Mass of Na = 34.5g
Use Avogadro's number which is numerically equal to ...
( 6.02 multiply by 10 to the power of negative 23)
Avocado's number is the number of particle(molecules, ions, atoms) present in one mole of substance.
number of molecule in 0.809 mole of h20 = ....
one mole of h20 contains (6.02* 10^-23)
0.809 mole contains....(6.02* 10^-23) (0.809)
which is equal to [4.951* 10 ^-23]
if I made no mistake in calculation...it must be correct
