Answer:

D. A new substance with properties different from either of the liquids was formed.

Explanation:

This is a simple chemical reaction. When chemical reactions occur, bonds are simply broken and rearranged and new ones formed. Formation of new compounds can be seen and clearly observed. These compounds are completely different in properties from the atoms and compounds that combines to form them.

If they still share the same property in anyway, then, there was only a physical combination of the compounds and this implies the formation of a mixture

Answer:

D. A new substance with properties different from either of the liquids was formed.

The correct option that is the answer for the question is option d

Explanation:

In the given question two liquids of different colours are mixed together. One of them has yellow colour, while the other is colourless on mixing we see that the new substance that is formed is neither yellow nor colourless.

And the mixture that is formed is a substance which is not liquid and solid of red colour and we can conclude, that the mixture form does not retain any property of the elements from which it is made. Hence we can say a new substance with different properties are formed.

Nikolas, the fire extinguisher, and the skateboard have a combined mass of 50 kg. What force would the fire extinguisher have to

murzikaleks [220]

Answer:

Force used by fire extinguisher = 60 N

Explanation:

Given:

Mass of skateboard with fire extinguisher = 50 kg

Acceleration of fire extinguisher = 1.2 m/s²

Find:

Force used by fire extinguisher = ?

Computation:

⇒ Force = Mass × Acceleration

⇒ Force used by fire extinguisher = Mass of skateboard with fire extinguisher × Acceleration of fire extinguisher

⇒ Force used by fire extinguisher = 50 kg × 1.2 m/s²

⇒ Force used by fire extinguisher = 60 N

a chemist adds of a calcium bromide solution to a reaction flask. calculate the mass in grams of calcium bromide the chemist has

mestny [16]

The mass of Calcium bromide added in the flask is 29.7 g.

<h3>What is Molarity? </h3>

Molarity is defined as the ratio of number of moles od solute to the number of volume of solution in litres.

Molarity = number of moles/ volume

<h3>Calculation of Moles</h3>

Number of moles = Molarity × volume

Given,

Molarity of Calcium bromide = 0.363 M

Volume of Calcium bromide = 410 mL

= 0.410L

By substituting all the value, we get

Number of moles = 0.363 × 0.410

= 0.148 mol

As we know that,

Molar mass of Calcium bromide = 199.89 g

Mole is defined as the given mass of substance to the molar mass of substance.

Given mass = Moles × Molar mass

= 0.148 × 199.89

= 29.75 g

= 29.7 g (significant digit)

Thus, we calculated that the mass of Calcium bromide added in the flask is 29.7 g.
