<h3>Answer;</h3>

Chemical bond

<h3>Explanation;</h3>

Chemical bond is an attraction that is formed between atoms or molecules which enables formation of chemical compounds.
Chemical bonds result from attraction of atoms to each other through the sharing of electrons, exchanging of electrons or the transfer of electrons or electrostatic forces.
Chemical bonds may be classified as metallic bond, ionic bond or covalent bond.
Ionic bonds occur when electrons are transferred from one atom to another, and the result is attraction between the resulting oppositely charged ions. Covalent bonds occurs as a result of sharing of electrons between non-metal atoms. Metallic bond occur in metals as a result of positively charged nucleus and a sea of electrons in the atoms.

Explanation:

When an atom bonds with another atom then it results in the formation of a chemical bond.

This formation of bond could be due to transfer or sharing of electrons.

When a chemical bond is formed due to transfer of electrons then this type of bond is known as ionic bond.

When a chemical bond is formed due to sharing of electrons then this type of bond is known as covalent bond.

Is gastric (stomach) fluid an acid or a base?

Vitek1552 [10]

Answer: the such thing that we call gastric acid, is made/produced by the cells that srebwithi any lining of our stomac, they are coupled in places like feedback system that extend to the acid production when it is needed.

other cells that are within our stomach will bicarbonat, at the base to buffer the fluid making sure that it doesn’t become too acidic

so yes it is

leva [86]

Answer:

0.5188 M or 0.5188 mol/L

Explanation:

Concentration is calculated as molarity, which is the number of moles per litre.

***Molarity is represented by either "M" or "c" depending on your teacher. I will use "c".

The formula for molarity is:

$c = \frac{n}{V}$

n = moles (unit mol)

V = volume (unit L)

Find the molar mass (M) of potassium hydroxide.

$M_{KOH} = \frac{39.098 g}{mol}+\frac{16.000 g}{mol}+\frac{1.008 g}{mol}$

$M_{KOH} = 56.106 \frac{g}{mol}$

Calculate the moles of potassium hydroxide.

$n_{KOH} = \frac{14.555 g}{1}*\frac{1mol}{56.106g}$

$n_{KOH} = 0.25941(9)mol$

Carry one insignificant figure (shown in brackets).

Convert the volume of water to litres.

$V = \frac{500.0mL}{1}*\frac{1L}{1000mL}$

$V = 0.5000L$

Here, carrying an insignificant figure doesn't change the value.

Calculate the concentration.

$c = \frac{n}{V}$

$c = \frac{0.25941(9)mol}{0.5000 L}$

$c = 0.5188(3) \frac{mol}{L}$ <= Keep an insignificant figure for rounding

$c = 0.5188 \frac{mol}{L}$ <= Rounded up

$c = 0.5188M$ <= You use the unit "M" instead of "mol/L"

The concentration of this standard solution is 0.5188 M.

You add 100.0 g of water at 52.0 °C to 100.0 g of ice at 0.00 °C. Some of the ice melts and cools the water to 0.00 °C. When the

lara31 [8.8K]

Answer:

$m_{ice} = 65.336\,g$

Explanation:

Accoding to the First Law of Thermodynamics, the heat released by the water melts a portion of ice. That is to say:

$Q_{water} = Q_{ice}$

$(100\,g)\cdot \left(4.184\,\frac{J}{kg\cdot ^{\textdegree}C}\right)\cdot (52\,^{\textdegree}C - 0\,^{\textdegree}C) = m_{ice}\cdot \left(333\,\frac{J}{g} \right)$

The amount of ice that is melt is:

$m_{ice} = 65.336\,g$
