Answer:
have stars that might appear to wobble
often have one star that is brighter than the other
Explanation:
A binary star system is a star system made up of mostly two stars that moves round their common fixed center.
The two orbiting stars are gravitationally bonded to one another and they move round each other.
Most binary stars might appear wobble. One of the stars often appears brighter than the other.
Answer:
58.316 is the formula weight of magnesium hydroxide
It is easier to determine this if we draw the structural formula of lactic acid as shown in the attached picture. There are three functional groups in lactic acid: carboxyl group, hydroxyl group, and the parent alkane chain. Any of the hydrogens in the alkane chain is the least acidic. Then, it is followed by the H in the hydroxyl group. The most acidic is the H in the carboxyl group.
Answer:
91.4°C
Explanation:
Gay - Lussac Law => T ∝ P => T = kP => k = T/P with volume (V) and mass (n) constant.
For two different Temperature (T)-Pressure (P) conditions
k₁ = k₂ => T₁/P₁ = T₂/P₂ => T₂ = T₁(P₂/P₁)
T₁ = 55°C = (55 + 273)K = 328K
P₁ = 965 mmHg
T₂ = ?
P₂ = 850 mmHg
T₂ = T₁(P₂/P₁) = 328K(850 mmHg/965 mmHg) = 364K = (364 - 273)°C = 91.4°C
