density = mass /volume

1)mass of rock = 26.0 gram

2)volume of rock = volume of water it has displaced= 25.3-13.12 = 12.18

put the value of mass and volume in first equation and get the density value

A bottle is partly filled with liquid water, sealed shut, and then placed under a heat lamp. The volume of the liquid water even
ANTONII [103]

Because the rate at which water vapour condenses gets increase slowly to get equal to the rate of evaporation of the water.

Explanation:

When a bottle is partly filled with liquid water is leaves space for vapours to escape and get condensed equally.

When sealed and kept below the lamp the rate of condensation increases due to the empty space in the bottle for getting vapours cool down.

A point arrives when evaporation equates the condensation of the liquid in bottle becomes stable because vapours cannot pass the bottle eventually condense and become liquid.

How many moles of hydrogen are needed to completely react with 2 moles of nitrogen
Natali5045456 [20]
Assuming ammonia is the product of this reaction:

N2+3H2--->2NH3

2 mole N2 * (3 mol H2)/(1 mol N2)= 6 mol H2

You would need 6 mol of hydrogen gas to completely react with 2 mol of nitrogen.

The partial negative charge at one end of a water molecule is attracted to the partial positive
Neporo4naja [7]

Answer:

             Hydrogen Bond

Explanation:

                   Hydrogen bond interactions are formed between the hydrogen atom bonded to most electronegative atoms (i.e. F, O and N) of one molecule and most electronegative atom (i.e. F, O and N) of another molecule.

In this interaction the hydrogen atom has partial positive charge and electronegative atom has partial negative charge.

A large piece of jewelry has a mass of 132.6 g. a graduated cylinder initially contains 48.6 ml water. when the jewelry is subme
Simora [160]

Answer:- Density is 10.5 grams per mL and the substance is Silver(Ag).

Solution:-  Mass of jewelry is given as 132.6 g. Initial volume of water in the graduated cylinder is 48.6 mL and the volume becomes 61.2 mL when this jewelry is submerged in the cylinder.

So, the volume of the jewelry = 61.2 mL - 48.6mL = 12.6 mL

We know that, density=\frac{mass}{volume}

Let's plug in the values in the above formula to calculate the density:

density=\frac{132.6g}{12.6mL}

density=10.5\frac{g}{mL}

So, the density of the jewelry is 10.5\frac{g}{mL} .

The substance from which the jewelry is made could easily be identified by comparing the calculated density with the density values given for different substances in the density table.

Looking at the density table, 10.5 grams per mL is the density for silver. So, the jewelry is made up from Silver.

why would you expect to see similar rocks and rock structures on two land masses that were connected at one time?
tangare [24]
If they were connected at one time than you would expect to find similar rock structures because they eroded, weathered, and we’re formed most likely at the same time out of the same material. So basically since they were near each other they were under the same or similar conditions.
