Answer:
it is an organic molecule
Explanation:
it's a compound called chromium, phosphate tetrahydrate, where tetra stands for 4 , as there are four water molecules attached to the compound.

The concept that can be used in order to answer this item is that of the conservation of heat among the system. We let T be equal to the final temperature. The equation that would allow us to relate the initial and final conditions of both substances is as follows,
m₁cp₁(T - T₁) = m₂cp₂(T₂ - T)
The first entity, 1, is the milk and the second entity, 2, is the coffee. We are given that the specific heats of both substances are just equal so we can eliminate them from the equation. Substituting the known values,
(10 g)(T - 10°) = (1.60 x 10^2 g)(90° - T)
The value of T from the equation is 85.29°C.
Answer: 85.29°C
The mass is
Explanation:
First, we need to find the volume of the cube.
v = lwh
v = (4)(4)(4)
v = 64 cubic cm
Now, since we know the volume and the density, we can figure out the mass.
The formula is mass = volume x density
Mass = 64 x 2.7
Mass = 172.8 g.
Therefore, the mass is 172.8 grams.
Hello!
The pressure of the Ideal Gas when the volume is 1,45 L and the temperature is 298 K is
1,82 atm.
To solve this problem we need to apply the
Ideal Gas Law for the initial conditions and the final ones, clearing the equation for the number of moles (n) and the ideal gas constant (R) which remain constant:

Now we match n*R for the initial conditions (1) and the final ones (2), clearing the equation for P₂
