Answer:
<h3>The answer is 0.67 cm³ </h3>
Explanation:
Density of a substance can be found by using the formula
<h3>

</h3>
Making volume the subject we have
<h3>

</h3>
From the question
mass of gold nugget = 13 g
Density = 19.3 g/cm³
Substitute the values into the above formula and solve for the volume
We have
<h3>

</h3>
= 0.673575
We have the final answer as
<h2>0.67 cm³</h2>

<h2>Answer:</h2>
D) The geosphere, hydrosphere, and atmosphere
<h2>Explanation:</h2>
During the carbon cycle, various processes move carbon from the geosphere to the atmosphere such as volcanic eruptions release carbon dioxide from molten rock beneath the earth's surface to the atmosphere. Carbon can leave the soil through soil respiration which releases CO2, or by erosion which can carry it into rivers or the ocean, where it then enters the hydrosphere. Carbon is found in the hydrosphere dissolved in ocean water and lakes and hence the cycle continues.
Question:
What occurs to the atoms of reactants in a chemical reaction?
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
Answer:
I believe
Explanation:
I believe that the answer is B, but I could be wrong. I think it's How much work can be done in a given time, because, In physics, power is the amount of energy transferred or converted per unit time.
Alkali metals impart characteristic colours to the flame due to low ionisation enthalpy, when an alkali metal or its salt is heated in a flame, the valence electrons are excited to higher energy level.
