Answer:
Explanation:
The explanation is given in the attached document.
The computation would be:moles = mass/ Molar Mass, but we are looking for the mass, so rearranging, will give us: mass = moles x MM
Q = moles x Hf
Q = (mass/MM) x Hf
mass = (Q x MM) / Hf
= (1.50-kJ x 18.0-g/mol) / 6.01-kJ/mol
=4.49 g H20 is the answer
A radiosonde is a lightweight package of measurements instruments
carried aloft by a helium balloon.
The radiosonde can be used to measure upper air temperature.
This is a true statement. Consequently, the better answer to choose
from among the choices provided is the ' T ' , apparently presented
here to suggest the word ' True ' .
Hi! The answer is C
As west is defined as negative, the trucks velocity is positive, since its travelling east. But its speed (absolute value of velocity) is decreasing, that means that the acceleration is negative.
