Answer:

Atoms is the smallest unit of a chemical element and consist of three main components protons, neutrons, and electrons.

The number of a neutron is based on the difference between the mass number of the atom (M) and the atomic number (Z). every isotope of an element has a different number of neutron.

But in a neutral atom or average atom, the number of neutrons is equal to the number of protons and the number of electron.

Example of the number of neutrons in an average atom: In Nitrogen-14, the atomic number and the number of protons is 7, it means the number of neutrons will also 7.

When the pressure that a gas exerts on a sealed container changes from 22.5 psi to psi the temperature changes from 110 c to 65.

ad-work [718]

Gay- Lussacs law states that the pressure of a gas is directly proportional to temperature for a fixed amount of gas at constant volume.
therefore P/T = k
where P - pressure , T - temperature and k - constant
$\frac{P1}{T1} = \frac{P2}{T2}
$
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 - temperature in kelvin - 110 °C + 273 = 383 K
T2 - 65.0 °C + 273 = 338 K
substituting these values in the equation

$\frac{22.5 psi}{383 K} = \frac{P}{338K}$
P = 19.9 psi
new pressure is 19.9 psi

Define saturated and unsaturated fats

REY [17]

Answer:

unsaturated fats, which are liquid at room temperature,are different from saturated fat because they contain one or more double bonds and fewer hydrogen atoms on their carbon chain.

Under what conditions does the hydrolysis of an amide bond occur?

Mademuasel [1]

Hi.

I did some digging and I think I found what you're looking for.

I found this on Q(uizlet)

basic or acidic conditions and the reactants must be heated.

An isomer with a branched structure will require:

Contact [7]

The branched structure isomer will require less energy to melt than the straight chain isomer

explanation
Branched structure isomer has weak intermolecular forces of attraction as compared to straight chain isomers. In addition the branched isomer has a low boiling point as compared to straight chain isomers. Since boiling require the of the intermolecular forces tend to have lower boiling point than straight chain

Write the balanced molecular and net ionic equations for the reaction between aluminum metal and silver nitrate. identify the ox

asambeis [7]

Well in this case, silver nitrate is reduced:

Ag+ + e− → Ag(s) ↓

Meanwhile, the aluminum is oxidized forming a positive ion:

Al(s) → Al3+ + 3e−

To get the overall reaction, we add the half equations so that the electrons are eliminated:

Al(s) + 3Ag+ → Al3+ + 3Ag(s)

And similarly:

Al(s) + 3AgNO3(aq) → Al(NO3)3(aq) + 3Ag(s)
