Given the equation: 2Na + 2H2O → 2NaOH + H2 Which substance in this equation is a binary compound?

Answers

Answer 1

Answer:

Answer: In the following equation, $H_2O$ is considered as a binary compound.

Explanation: A binary compound is considered as a compound having 2 elements only. In the following chemical equation:

$2Na+2H_2O\rightarrow 2NaOH+H_2$

There are 2 compounds present because compound is defined as the chemical combination of two or more elements in a fixed ratio.

In the equation, compounds are: $H_2O$ and $NaOH$

$H_2O$ consists of 2 elements which are hydrogen and oxygen and hence is considered as a binary compound.

$NaOH$ consists of 3 elements which are sodium, hydrogen and oxygen and hence, cannot be considered as a binary compound.

What relationship do you observe between the temperature and density?

Answers

Answer:Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

During an experiment, a student observes the formation of a precipitate. Why does this indicate that a chemical reaction is likely occurring?

Answers

The formation of a precipitate is always caused by a chemical reaction between a liquid solution and a precipitant. When solid particles suddenly appear in a sample of liquid under experimentation, that is an obvious sign that a reaction has occurred. Precipitates possess various qualities such as color and size. The only exception to this is when a precipitate forms when solubility of a solute is exceeded.

Answer:

A solid forms, and there is a change of color.

What should you look for in a chemical formula to decide is a compound or element will not combust

Answers

To determine whether a chemical formula represents a compound or element that will not combust, you need to consider the elements present in the formula and their respective properties.

How we can determine combustibility?

First, check if the formula contains only one type of element. If it does, then it represents an element, and the question of whether it will combust or not is irrelevant, as elements do not combust.

If the formula contains two or more different elements, then it represents a compound. To determine if the compound will combust, you need to look at the properties of its constituent elements.

Some elements, such as noble gases (e.g., helium, neon, argon), have very low reactivity and are unlikely to combust under normal conditions. Therefore, if the compound contains only noble gases, it is unlikely to combust.

Other elements, such as metals, are more reactive and can combust under certain conditions, such as exposure to heat or oxygen. Therefore, if the compound contains a metal, you need to check the reactivity of that metal to determine if the compound will combust.

Similarly, non-metals can also be combustible under certain conditions, such as exposure to heat or other reactive substances. Therefore, if the compound contains a non-metal, you need to check the reactivity of that non-metal to determine if the compound will combust.

Overall, to determine if a compound or element will combust, you need to consider the properties of its constituent elements and any external conditions that may affect its reactivity.

You will look at its number lets say if you had H2O which is two hydrogen and one oxygen. The two hydrogen is combined with oxygen sharing it's electrons making it being covalent bonding. You need 8 valence electrons that meaning full outershell. Hydrogen only has one in it outershell oxygen has 6 that's what can make a compound
