Answer:

According to the proton theory of acids and bases by J. Brønsted and T. Lowry, the acid is<u> proton donor</u>.

Explanation:

According to the Bronsted lowry concept an acid is substance that gives protons or hydrogen ion while,

Base is substance that accept hydrogen ion or proton.

Consider the following example:

NH₃ + HCl → NH₄⁺ + Cl⁻

In this example HCl is Bronsted lowry acid it gives H⁺ while ammonia is Bronsted lowry base because it accept H⁺.

This also gives the concept of conjugate acid and base. In given example Cl⁻ is conjugate base of HCl while NH₄⁺ is conjugate acid of ammonia.

What Happens When extra Solute is added to unsaturated ,saturated and supersaturated solution

Ymorist [56]

of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated. If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated.

You have 28.5 g of iron shot that has a volume of 3.60 mL. From this information, calculate the density of iron.

laila [671]

Answer:

$\boxed {\boxed {\sf \rho \approx 7.917 \ g/mL}}$

Explanation

Density can be found by dividing the mass by the volume.

$\rho=\frac{m}{v}$

We know the iron sheet has a mass of 28.5 grams and the volume is 3.60 milliliters.

$m= 28.5 \ g \\d= 3.60 \ mL$

Substitute the values into the formula.

$\rho=\frac{28.5 \ g}{ 3.60 \ mL}$

Divide.

$\rho = 7.91666667 \ g/mL$

Let's round to the nearest thousandth.

The 6 in the ten-thousandth tells us to round the 6 to a 7.

$\rho \approx 7.917 \ g/mL$

The density of iron is about <u>7.917 grams per milliliter.</u>

The density of a sample of metal is calculated using these three different sets of data: 1.2 g/mL, 1.4 g/mL, and 1.1 g/mL. If th

Iteru [2.4K]

Accurate data means the data experimentally obtained are close to the true value. Precise data means the data obtained are close to one another. In this case, the data are close to the true value which is 1.2 and the data are relatively close to one another. Hence the set is both accurate and precise.
