Specific heat is the amount of heat absorb or released by a substance to change the temperature to one degree Celsius. To determine the specific heat, we use the expression for the heat absorbed by the system. Heat gained or absorbed in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:
Heat = mC(T2-T1)
By substituting the given values, we can calculate for C which is the specific heat of the material.
2510 J = .158 kg ( 1000 g / 1 kg) (C) ( 61.0 - 32.0 °C)C = 0.5478 J / g °C
Answer: The are bodies of rock or gas that are named for ancient gods.
Explanation:
Earth is the THIRD planet in the solar system. It support life of all living organisms.
VENUS is the second planet in our solar system. It is named after the Roman goddess of love and beauty.
MARS is the fourth planet in our solar system. It is named after the Roman goddess of war.
Thus, Venus and Mars, are EARTH NEIGHBORS
Predators decreased, food source increased, migration patterns, natural disaster or threat in normal habitat.
Answer:
The correct option is b. an amino-terminal signal
Explanation:
A polypeptide that will eventually fold to become an ion channel protein, it means a kind of integral membrane protein, has an amino terminal signal that indicates its delivery to endoplasmic reticulum (ER) and then to the membrane. This type of signal usually consist in a nucleus of 6 to 12 aminoacids and one or more basic aminoacids. Once the polypeptide enters the ER, this signal is removed.
Molar mass CaCl₂ = 110.98 g/mol
Number of moles:
1 mole CaCl₂ ---------> 110.98 g
n mole CaCl2 ---------> 85.3 g
n = 85.3 / 110.98
n = 0.7686 moles of CaCl₂
Volume = ?
M = n / V
0.788 = 0.7686 / V
V = 0.7686 / 0.788
V = 0.975 L
hope this helps!
