then the electrons and protons would have a even amount of negetive electric charges
The partial pressure of hydrogen is 0.31 atm
calculation
find the number of hydrogen moles the container, that is
25/100 x 6.4 =1.6 moles of hydrogen
find the partial pressure for hydrogen in 1.6 moles
that is 6.4 moles= 1.24 atm
1.6 moles= ?
by cross multiplication
1.6moles x1.24 atm/ 6.4 moles= 0.31 atm
Answer:
D. Malleability
Explanation:
Gold is made up of the element Au and it is a metal.
Pyrite is iron sulfide and it is a non-metal.
- They have very similar appearance to such an extent that pyrite is widely called the fool's gold.
- To distinguish between the two, we simply explore their metallic properties.
- Gold is malleable. Pyrite is not. It will crumble under pressure.
Answer:
2.8 g/mL is the density of the mineral.
Explanation:
The mass,
Volume of the object = Volume of water level rose - Initial volume of water = 30.5 mL - 20.3 mL = 10.2 mL
The expression for the calculation of density is shown below as:-
<u>2.8 g/mL is the density of the mineral.</u>
Answer:
Explanation:
125 cm3 -> 0.125 L
M = no. mole / volume (L)
M = 0.25 / 0.125 = 2 M
