Answer:

The solubility increases with temperature.

The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

A piece of metal with a mass of 17.1 g was dropped into a graduated cylinder containing 17.00 mL of water. The graduated cylinde
Mademuasel [1]

The density of the metal with a mass of 1.71g that was dropped into a graduated cylinder containing 17.00 mL of water is 1.005g/mL.

<h3>How to calculate density?</h3>

The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;

Density = mass ÷ volume

According to this question, a piece of metal with a mass of 17.1 g was dropped into a graduated cylinder containing 17.00 mL of water. The density can be calculated as follows:

Density = 17.1g ÷ 17.00mL

Density = 1.005g/mL

Therefore, the density of the metal with a mass of 1.71g that was dropped into a graduated cylinder containing 17.00 mL of water is 1.005g/mL.

The burning of propane gas can be represented as a balanced chemical reaction as follows: C3H8(g)+5O2(g)→3CO2(g)+4H2O(g) Calcula
Snezhnost [94]

Answer: 20L of H2O

Explanation:

C3H8 + 5O2 → 3CO2 + 4H2O

Recall 1mole of a gas contains 22.4L at stp

5moles of O2 contains = 5 x 22.4 = 112L

4moles of H2O contains = 4 x 22.4 = 89.6L

From the equation,

112L of O2 produced 89.6L H2O

There for 25L of O2 will produce XL of H2O i.e

XL of H2O = (25 x 89.6)/112 = 20L

Copper has an atomic number of 29 and a mass number of 64. what would result if an uncharged copper atom lost two electrons?
nikklg [1K]

The atomic mass of an element is the number of times of an atom of that element is  heavier than an atom of carbon taken as 12. In simpler way, atomic mass is number of protons present in  nucleus of an atom, which is a characteristic of an chemical element and is determines place of the element in the periodic table.  Mass number is total number of protons and neutrons. If an uncharged atom looses electron from its outermost shell, it becomes cation, which is positively charged species. Atomic number and mass number do not change if electron goes out of an atom.

Uncharged copper after loosing two electrons is converted to Cu^{2+} which can be represented as follows:

Cu_{29} ^{64}→Cu^{2+}
