Explanation:
6.022x10^23 is correct answer
Negative symbol which means that gain of electron.
I not sure about the answer sorry!! if you will get wrong in your book
Answer:
Covalent bonds
Explanation:
Atoms with greatly differing electronegativity values are expected to form..... ... When two atoms each need additional electrons to fill their valence shells, but neither is electronegative enough to steal electrons from the other, they can form another kind of chemical bond called a covalent bond.
Answer:
E
Explanation:
no of grams in picture c = A+B
= 200+10 =210
for D its also 210 ..... the water already contains the salt .....so the mass of salt has added to the mass of water which is still 210
that's all .... have fun
Answer:
The final temperature at 1050 mmHg is 134.57
or 407.57 Kelvin.
Explanation:
Initial temperature = T = 55
= 328 K
Initial pressure = P = 845 mmHg
Assuming final to be temperature to be T' Kelvin
Final Pressure = P' = 1050 mmHg
The final temperature is obtained by following relation at constant volume

The final temperature is 407.57 K
