An atom of 110Sn has a mass of 109.907858 amu. Calculate the mass defect in amu/atom. Enter your answer with 4 significant figur

es and no units.
Use the masses: mass of 1H atom = 1.007825 amu

mass of a neutron = 1.008665 amu

1 amu = 931.5 MeV

The correct answer is 1.003

Calculate the specific heat capacity of a piece of ice if 1.30 kg of the wood absorbs 6.75×104 joules of heat, and its temperatu

Gre4nikov [31]

Answer:

$c=2.0769\ \frac{J}{g\ \textdegree C}$

Explanation:

-Specific heat capacity is given by the formula:

$q=mc\bigtriangleup T$

Where:

$q$ is the heat gained or loosed by the substance

$m$ is the mass of the substance

$c$ is the specific heat of the substance

$\bigtriangleup T$ is the change in temperature

#We make c the subject of the formula and substitute to solve for it:

$q=mc\bigtriangleup T\\\\c=\frac{q}{m\bigtriangleup T}\\\\\bigtriangleup T=(57-32)\textdegree C=25\textdegree C\\\\\therefore c=\frac{6.75\times 10^4J}{1.3\times 1000\ g\times 25\textdegree C}\\\\=2.0769 \ \frac{J}{g\ \textdegree C}$

Hence, the specific heat capacity of the ice is $2.0769 \frac{J}{g\ \textdegree C}$

krok68 [10]

Answer:

Calcium (Ca²⁺)

Explanation:

Calcium is very important mineral, found in teeth and bones primarily.

It is needed for the strong bones.

It is very important to maintain the bones in order to support our skeleton.

In our body it is also important to carry out other functions like in muscles, nerve function and also for heart.

If our diet is not full of calcium, the calcium deficiency may occur which leads to the weakening of bones and cause fracture.

The dietary source of calcium includes:

Yogurt, cheese, milk

beans such as peas, peanuts.

fishes

almonds, oranges, molasses

6. Identify the number of neutrons in one atom of silicon with an isotopic mass number of 28 amu.

Sholpan [36]

14

Explanation:

The number of neutrons in one atom of silicon with an isotopic mass number of 28amu is 14.

An atom is made up three fundamental sub-atomic particles which are:

Protons, neutron and electrons

Protons are the positively charged particles in an atom

Neutrons do not carry any charges

Electrons are the negatively charged particles.

In the nucleus of an atom, both protons and neutrons can be found. They are the massive particle in an atom.

The mass number of an atom = number of protons + number of neutrons

Number of neutrons = mass number - number of protons.

From the periodic table, we know that silicon has an atomic number of 14.

The atomic number is the number of protons in an atom:

Number of neutrons = 28 - 14 = 14amu

In the atom, we will have 14amu of neutrons in a silicon atom.
