Answer:

Nitrogen

Explanation:

The element nitrogen cannot be a product in the given reaction.

The reaction is;

HCl + CaCO₃

According to the law of conservation of matter, "matter is neither created nor destroyed in the cause of a chemical reaction".

The law suggests that, in a chemical reaction, we end up with the same species we started with. Although due to rearrangement of bonds, new compounds can form;

Starting atoms

These species will also be found in the product.

Arrange the three common unit cells in order from least dense to most dense packing. a. face-centered cubic < body-centered c

maks197457 [2]

Answer:

b. primitive cubic < body-centered cubic < face-centered cubic

Explanation:

The coordination number is defined as the number of atoms (or ions) surrounding an atom (or ion) in a crystal lattice. Its value gives us a measure of how tightly the spheres are packed together. The larger the coordination number, the closer the spheres are to each other.

In the primitive cubic, each sphere is in contact with 6 spheres, so its coordination number is 6.

In the body-centered cubic, each sphere is in contact with 8 spheres, so its coordination number is 12.

In the face-centered cubic, each sphere is in contact with 12 spheres, so its coordination number is 12.

Therefore, the increasing order in density is the primitive cubic first, then the body-centered cubic, and finally the face-centered cubic.

A quantity of water is heated from 25.0°C to 36.4°C by absorbing 325 J of heat energy. If the specific heat of water is 4.18 J /

Arlecino [84]

Answer:

6,8 g

Explanation:

c = 4.18 J/(g * °C) = 4180 J / (kg * °C)

$t_{1}$ = 25 °C

$t_{2}$ = 36,4 °C

Q = 325 J

The formula is: Q = c * m * ( $t_{2} - t_{1}$ )

m = $\frac{Q}{c * (t_{2} - t_{1} )}$

Calculating:

m = 325 / 4180 * (36,4 - 25) ≈ 0,0068 kg = 6,8 g
