Answer:
<h3>The answer is 0.67 cm³ </h3>Explanation:
Density of a substance can be found by using the formula
<h3>Making volume the subject we have
<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>= 0.673575
We have the final answer as
<h2>0.67 cm³</h2>Hope this helps you
Answer:
Q = 319.49 J
Explanation:
Given that,
Mass, m = 16.6 g
Initial temperature,
We need to find the heat needed to warm the water to 44.8 °C. The formula that is used to find the heat required is given by :
So, 319.49 J of heat is needed to warm water.
Answer: Option (C) is the correct answer.
Explanation:
A neutral hydrogen atom is defined as the atom in which electrons are resent in their ground state only.
Basically in a neutral atom electrons are present in their parent shell.
For example, atomic number of hydrogen is 1 and electronic configuration of a neutral atom of hydrogen is .
Hence, it means there is only one electron present in its valence shell. So, in order to attain stability it will readily react with another atom to gain or share an electron.
Thus, we can conclude that the statement it is less chemically reactive than an atom of aluminum (Al), is false.
