Metallic bond is a force that holds atoms together in a metallic substance.

Answer:

Metallic bonds are bonds between metals. Metals lose their valence electrons holding the positive metal ions together due to the strong forces of attraction. [Electrons are negatively charged, so the positive metal ions and the electrons attract to each other]

What is the concentration of chloride ion in a 2.0 M solution of calcium chloride
lbvjy [14]
All you have to do is multiply by two, since calcium chloride has the chem. formula, CaCl2. For every 1 mole of CaCl2, you'll have 2 mole of chloride ions in solution.

A sealed vessel initially contains 100 g of chlorine gas and 90 g of hydrogen gas. The two gases undergo reaction to form HCl. W
EleoNora [17]

Answer:

d.

Explanation:

H2 + Cl2 = 2HCL

From the equation 2g hydrogen combine with 71g of chlorine.

So 35.5 g Cl2 combines with 1g of H2

There are 100g of Cl2 so this will, by proportion, react with 100/35.5 g hydrogen.

This is 2.8 g hydrogen so the mass of HCl formed = 102.8 g.

Answer:

  • <u><em>It will be less than 26 °C as water has a relatively higher specific heat than sand.</em></u>

Explanation:

The <em>specific heat </em>of a substance is the amount of heat energy absorbed by one unit of mass of the substance when its temperature increases one unit.

From that, you can derive the equation for the specific heat of a substance:

  • specific heat = heat / (mass × ΔT)

Thus, assuming that all the heat provided by the lamp to both samples is the same and, as given, the amount (mass) of both samples is also the same, you have that the specific heat of the samples will be:

  • specific heat = constant / ΔT

So, specific heat and ΔT are inversely related.

It is known that water has a higher specific heat than sand (that is why the sand on the shore of a beach is, during the day, hotter than the water and your feet get burned when you walk on a sandy beach on a sunny day).

Then, since the specific heat of water is greater than the specific heat of sand, the increase of temperature of water will be lower and, consequently, water will reach a lower final temperature than sand, when equal amounts of water and sand are heated as described in the experiment. This is the second choice: the final temperature of water is less than 26°C as water has a relatively higher specific heat than water.
