fluorine
Explanation:
I used the number of electrons to determine it.
Answer:
Sodium Hydroxide is an ionic compound formed by two ions, Sodium Na+ and Hydroxide OH− . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it take one +1 sodium ions to balance the one -1 hydroxide ion. This will make the formula for Sodium Hydroxide NaOH
Explanation:
The temperature in degree celsius to which the gas was heated is calculated using the Charles law formula
that is V1/T1 =V2/T2
V1=88.2 ml
T1=35 +273 = 308 K
V2=123 ml
T2=?
by making T2 the formula of the subject T2=V2T1/V1
=(123 ml x308 k)/88.2 ml =429.5 K
in degree celsius = 429.5 -273= 156.5 degree celsius
Answer:
The correct option is A
Explanation:
Water from a river is used for many activities in a community. These activities could include (but not limited to) tourism, drinking for animals, local transport, irrigation for nearby farming, recreation (as in swimming), habitat for some living organisms among others. Rivers are not limited by what limits the influence of oceans such as taste (it's saltiness, which cannot be used in farming also) and wave current.
Answer:
¾ litters of water was consumed
2.24 litters = 1 mole of water
Therefore ¾÷2.24 moles was consumed
0.33 moles
