Answer:

Groups 13-16.

Explanation:

There are 18 groups in the periodic table.

The first and second group contains only metal (alkali and alkaline earth metals)

The third to twelfth group (3-12) also contains only metals (the transition metals and inner transition metals).

Now the groups from 13 to 18 contains metals, non metals and metalloids

group 17-18 are strictly non metals

Thus the metalloids find their place in groups 13-16.

C. Groups 13-16 contain metalloids.

If you look on a periodic table, these usually have a different color.

A scientist measures the standard enthalpy change for the following reaction to be 67.9 kJ:

bekas [8.4K]

Answer: The standard enthalpy of formation of $H_2O(g)$ is -252.1 kJ/mol.

Explanation:

The balanced chemical reaction is,

$Fe_2O_3(s)+3H_2(g)\rightarrow 2Fe(s)+3H_2O(g)$

The expression for enthalpy change is,

$\Delta H=[n\times H_f_{products}]-[n\times H_f_{reactantss}]$

Putting the values we get :

$\Delta H=[2\times H_f{Fe}+3\times H_f{H_2O}]-[1\times H_f{Fe_2O_3}+3\times H_f{H_2}]$

$67.9kJ=[(2\times 0)+(3\times H_f{H_2O})]-[(1\times -824.2kJ/mol)+3\times 0kJ/mol)]$

$H_f{H_2O}=-252.1kJ/mol$

Thus standard enthalpy of formation of $H_2O(g)$ is -252.1 kJ/mol.

If the speed of a sound wave increases what other property of the wave must also increase when all other wave properties are hel

kati45 [8]

<h2>Frequency</h2>

Explanation:

Wave frequency is the number of waves that pass a fixed point in a given amount of time.

Wave speed is the speed at which a wave travels.

Let the wave speed be $v$

Let the wave frequency be $f$

Let the wave length be $l$

The wave speed,frequency and wave length are related by the equation $v=f\times l$ .

When $v$ increases, $f$ increases on the other side to maintain equality when no other property is changing.

What does it mean to say an equation is balanced? Why is it important for an equation to be balanced?

Rom4ik [11]

Answer: It is important for an equation to be balanced because if it is not then the reactants won't match the products.

Explanation: I don't know if you will understand this but here:

Let's say you're cooking eggs, you're reactants so to speak would be 3 eggs and 1 tablespoon of oil so you put it together using heat and a pan. Your products have to match what you have in the beginning. You cannot have an equation that looks like this

Reactants = 3eggs + 1Tbsp oil ---pan/heat---> 6eggs + 1 cup of oil

You cannot get something from what you don't have. The number of how much of an element you have must be the same of both sides of the equation.
