We have the following variables
note: the symbol is the uppercase Greek letter delta. It represents the difference or change in a value.
Apply those values into the formula below. Solve for c.
The specific heat of the unknown metal is roughly
Answer:
Explanation:
Assuming that temperature is constant
According to Boyle's Law, at constant temperature pressure is inversly proportional to the volume and mathematically it can be expressed as:
..........1
from the first equation after putting all the value
we get,
Answer:
The oxygen will occupied 84.7 L.
Explanation:
Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.
The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:
P*V = n*R*T
where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas. The universal constant of ideal gases R has the same value for all gaseous substances.
In this case:
Replacing:
768 mmHg* V= 3.5 mol* 62.36 *298 K
Solving:
V= 84.7 L
<u><em>The oxygen will occupied 84.7 L.</em></u>
Answer:
1.66 * 10^-18 mol of Argon
Explanation:
Avogadro says 1 mol of anything has 6.022* 10^23 atoms/particles. Thus using this principle, 1 million argon atoms will have
