<u>Answer:</u> The word equation for the given chemical equation is given below.

<u>Explanation:</u>

Word equation is defined as the equation in which substances are written in word form and not in chemical formulas. The words "and" or "plus" means that one substance and another substance are both reactants or products.

For the given chemical equation:

K(s)+H_2O(l)\rightarrow KOH(aq.)+H_2(g)

The word equation for this follows:

\text{(Potassium)}(s)+\text{Water}(l)\rightarrow \text{(Potassium hydroxide)}(aq.)+\text{Hydrogen gas}(g)

Here, 1 mole of potassium metal reacts with liquid water to produce 1 mole of potassium hydroxide and 1 mole of hydrogen gas.

Hence, the word equation for the given chemical equation is given above.

How many atoms are there in 10.2 moles of Phosphorous?​
nikdorinn [45]

There are 2.06 x 10²⁴ atoms

<h3>Further explanation </h3>

The mole is the number of particles (atoms, molecules, ions)contained in a substance

1 mol = 6.02.10²³  particles

Moles can also be determined from the amount of substance mass and its molar mass

  • number of atoms :

\tt 10.2\times 6.02\times 106{23}=2.06\times 10^{24}

Calculate the atomic mass for copper using the weighted average mass method. Express your answer using two decimal places and in
tatuchka [14]

Answer:

63. 55 amu

Explanation:

Copper is known to exist in two different isotopes which are Cu-63 and Cu-65.

Cu-63 has an atomic mass of 62.93 amu and it has an abundance of 69.15%.

Similarly,

Cu-65 has an atomic mass of 64.93 amu and it has an abundance of 30.85%

Therefore, using the weighted average mass method, the atomic mass of copper is:

Atomic mass of copper = (0.6915*62.93) amu + (0.3085*64.93) amu = 43.52 amu + 20.03 amu = 63.55 amu

Thus, the atomic mass of copper (express in two decimal places) is 63.55 amu
