Answer:
The answer is
<h2>0.307 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of box is 345 g
volume = 1125 cm³
The density of the object is

We have the final answer as
<h3>0.307 g/cm³</h3>

Paper burning is a form of a physical change known as combustion. The chemical bonds in between atoms holding them together are being changed with the heat, making it different on an atomic level.
Hello,
Question- Igneous rock can _____ to form metamorphic rock.

Answer:
The experimental feature of the MALDI-MS technique which allows the separation of ions formed after the adduction of tissue molecules:
B) Velocity of ions depends on the ion mass-to-charge ratio.
Explanation:
- The option a is not correct as distance traveled by ions doesn't depend upon the ion charge rather it depends upon time for which you leave the sample to run.
- The option b is correct as velocity of ions depends on the ion mass-to-charge ratio because separation is done due to mass to charge ratio feature.
- The option c is incorrect as time of travel is not inversely proportional to the ion-to-mass ratio because the ion will move across the gel until you stop the electric field.
- The option d is not correct as electric field between MALDI plate and MS analyzer is though uniform but this feature doesn't allow the separation of ions.
In an ionic bond, electrons are transferred from one stone to another atom (shared).
