C.
Particles will also move faster.
Answer:
69.196
Explanation:
<em><u>using ideal gas </u></em><em><u>equation</u></em>
- PV= nRT
- n= mass/molar mass
- PV=mass/molar mass x RT
- R = 62.364LTorrmol-¹k-¹
- make molar mass subject of formula
- m.m=(massxRT)/PV
- m.m = (0.687 x 62.364 x373)/(775 x 0.298)
- m = 69.196
To know that compare the electronegativitis of the two elements.
The electronegativity of H is 2.2
The electronegativity of Br is 2.96
The difference does not seem enough to cause ionic bond. Then it is most likely thaty they form a polar covalent bond.
Answer:
C
Explanation:
Natural gas is a non renewable source of energy since it is a type of fossil fuel so it is a non renewable resource.
Cu (s) + 2AgNO3 ---> 2Ag + Cu(NO3)2
=13.5 moles Silver Nitrate
