Answer:

The answer is

<h2>2.74 g/mL</h2>

Explanation:

The Density of a substance can be found by using the formula

density =  \frac{mass}{volume}

From the question

mass of rock = 12.34 g

volume = final volume of water - initial volume of water

volume = 54.5 mL - 50 mL = 4.5 mL

So the density is

density =  \frac{12.34}{4.5}  \\  = 2.744444444...

We have the final answer as

<h3>2.74 g/mL</h3>

Hope this helps you

Answer:

Grinding or breaking an Alka-Seltzer tablet increases the number of particles and increases the surface area. Material which was within the tablet is exposed, allowing for more collisions between reactant particles and resulting in an increased rate of reaction.

Name the plant cell organelle where<br> photosynthesis occurs.
Alexeev081 [22]

Answer:

chloroplast organelle

Answer. The photosynthesis process takes place in the chloroplast organelle in the growing tissues. As the chlorophyll pigment is available in the chloroplast organelle which is the main photosynthetic pigment, with the help of the molecules they capture the energy of light.

Explanation:

chloroplasts

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

What is the 3-dimensional orientation of a sublevel known as?
RoseWind [281]

The 3-dimensional orientation of a sublevel is known as atomic orbital.

In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.

Each sublevel has an orbital and it is oriented differently in 3-dimensional space.

The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.

ddd [48]

<u>Answer:</u> The amount of heat released is 56 MJ.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}  

Given mass of C_2H_6 = 12 kg = 12000 g    (Conversion factor: 1 kg = 1000 g)

Molar mass of C_2H_6 = 30 g/mol

Putting values in above equation, we get:

\text{Moles of }C_2H_6=\frac{12000g}{30g/mol}=400mol

The chemical reaction for hydrogenation of ethene follows the equation:

C_2H_4+H_2\rightarrow C_2H_6

By Stoichiometry of the reaction:

When 1 mole of ethane releases 140 kJ of heat.

So, 400 moles of ethane will release = \frac{140}{1}\times 400=56000kJ of heat.

Converting this into Mega joules, using the conversion factor:

1 MJ = 1000 kJ

So, \Rightarrow 56000kJ\times (\frac{1MJ}{1000kJ})=56MJ

Hence, the amount of heat released is 56 MJ.
