Answer:
The current temperature is -15° (15° below zero)
Explanation:
The temperature drops 10°:
T-10°
It will reach 25° below zero:
T - 10° = -25°
We add 10° in both members of the equation:
T - 10° +10° = -25° +10°
The equation is simplified as follows:
T = -25° +10°
T = -15°
The integer -15° can be expressed as 15° below zero.
Answer:
sugar and oxygen
Explanation:
sugar (glucose) and oxygen
They are different because they formed at different distances from the sun.
Answer:
Explanation:
A childs lung can hold .11mols/ per 2.8 L so that gives us a molarity of .039M
A adults lungs can hold .18 mols /per 4.6 so that gives us .039M aswell meaining that the lung capacity between the two is not different.
NaCl is made of Na and Cl
The molar mass of Na = 22.989 g/mol
The molar mass of Cl = 35.453 g/mol
Molar mass of NaCl = 22.989 + 35.453
= 58.44 g/mol
