Answer:

Metal is named first

Explanation:

Binary compounds:

The compounds which are made up of the atoms of only two elements are called binary compounds.

For example:

The following compounds are binary:

HCl

NaCl

HCl is binary because it is composed of only hydrogen and chlorine.

Sodium chloride is also binary compound composed of only two element hydrogen and chlorine.

When naming these compounds the name of metal or cation is written first and anion is written after the cation. The anions are non meals.

The anion name is end with suffix " ide".

such as sodium chloride.

1.) What is the difference between renewable and nonrenewable resources?

mash [69]

Answer: 1.) renewable resources can be replenished as fast as they are used. Nonrenewable resources are unable to be replaced at the same rate at which they are used. 2.) nonrenewable energy sources will eventually run out, leaving people to figure out how to continue running their cars, homes, and busines. They must find alternative sources of energy. Since renewable energy resources that will never run out, it is a great option.

A solid mixture consists of 47.6g of KNO3 (potassium nitrate) and 8.4g of K2SO4 (potassium sulfate). The mixture is added to 130

IgorLugansk [536]

Answer: No crystals of potassium sulfate will be seen at 0°C for the given amount.

Explanation:

We are given:

Mass of potassium nitrate = 47.6 g

Mass of potassium sulfate = 8.4 g

Mass of water = 130. g

Solubility of potassium sulfate in water at 0°C = 7.4 g/100 g

This means that 7.4 grams of potassium sulfate is soluble in 100 grams of water

Applying unitary method:

In 100 grams of water, the amount of potassium sulfate dissolved is 7.4 grams

So, in 130 grams of water, the amount of potassium sulfate dissolved will be $\frac{7.4}{100}\times 130=9.62g$

As, the soluble amount is greater than the given amount of potassium sulfate

This means that, all of potassium sulfate will be dissolved.

Hence, no crystals of potassium sulfate will be seen at 0°C for the given amount.

Difference between Rapid and spontaneous composition

Over [174]

Answer:

spontaneous composition is the ingnition

of the substance due to the repid oxidation of its on material.

There is no requirement of heat of external sources.

Rapid composition on the other hand release large amount of heat and light energy.

Explosion and the firecracker is the best example of Rapid composition.

Will reward brainliest Explain why all arrhenius acids can be considered bronsted lowry acids

GuDViN [60]

Answer:

Explanation:

A bronsted lowry acid just means that it donates a proton.

An arrhenius acid dissolves in water to donate a proton

the only difference is that an arrhenius acid must dissolve in water but it still donates a proton so it is considered a bronsted lowry acid
