A rock has a mass of 15 grams and a volume of 5 cm3 what is the density of the object

Chemistry
1 answer:
Zina [86]3 years ago
5 0

Answer:

The answer is

<h2>3.0 g/cm³</h2>

Explanation:

To find the density of a substance when given the mass and volume we use the formula

<h3>density =  \frac{mass}{volume}</h3>

From the question

mass = 15 g

volume of rock = 5 cm³

The density of the substance is

density =  \frac{15}{5}

We have the final answer as

<h3>3.0 g/cm³</h3>

Hope this helps you

If water were a non-polar<br> Molecule
JulijaS [17]

Answer:

Water would not be able to transport nutrients -‐-‐ in plants, or in our bodies -‐-‐ nor to dissolve and transport waste products out of our bodies. ... Cohesiveness, adhesiveness, and surface tension: would decrease because without the +/-‐ polarity, water would not form hydrogen bonds between H20 molecules.

How do you balance a chemical equation
Dominik [7]
There should be mass balance and the charge balance between the reactants and the products

Mass balance : total no of individual atoms of each type should be balanced before and after the reaction

Charge balance : Overall charge of the reactants should be balanced with the overall charge of the products

You can balance,

1)by just looking at it

2)by Algebraic method given above or

3)by the redox method

You need to know how to get the oxidation numbers in order to use the oxidation method

A 70.-kg person exposed to ⁹⁰Sr absorbs 6.0X10⁵ β⁻ particles, each with an energy of 8.74X10⁻¹⁴ J.(c) What is the equivalent dos
postnew [5]

A 70.-kg person exposed to ⁹⁰Sr absorbs 6.0X10⁵ β⁻ particles, each with an energy of 8.74X10⁻¹⁴ J.

<h3>What is β⁻ particles ?</h3>

A beta particle, also known as a beta ray or beta radiation (symbol ), is a highly energetic, swiftly moving electron or positron that is released during the radioactive disintegration of an atomic nucleus. Beta decay occurs in two ways: decay and + decay, which result in the production of electrons and positrons, respectively.

In air, beta particles with an energy of 0.5 MeV have a range of roughly one meter; the range is energy-dependent.

Ionizing radiation of the sort known as beta particles is regarded, for the purposes of radiation protection, as being more ionizing than gamma rays but less ionizing than alpha particles. The damage to live tissue increases as the ionizing effect increases, but so does the radiation's penetration power.
