Answer:
Consider how the speaker begins the speech, the support given in the body of the speech, and how the speaker concludes. Listen for changes in tone. Listen for how the speaker uses delivery techniques such as pauses, pace, voice, metaphors and symbolism, repetition and parallelism, and vocabulary.
Explanation:
The products of reaction are ZnSO4 and H2. Since ZnSO4 is in aqueous form (aq), therefore only H2 and water vapor contributes to the overall total pressure in the system.
Total Pressure = 764 torr = H2 partial pressure + Water partial pressure
Since Water partial pressure is 26.74 torr so,
H2 partial pressure = 737.26 torr = 0.97 atm
Answer:
Formula of magnesium oxide is MgO and formula of strontium oxide is SrO
Explanation:
Ca, Mg and Sr are same group bivalent metals.
Oxygen is a bivalent element
In general, formula of a compound made of a cation
and an anion
is
for 
When x = y, formula of the compound becomes MA
As both these metals and oxygen are bivalent therefore formula of magnesium oxide is MgO and formula of strontium oxide is SrO.
Answer:
"1 M" will be the right solution.
Explanation:
The given values are:
Number of moles,
= 2 moles
Volume of solution,
= 2000 mL
or,
= 2 L
