Answer:

Atoms are composed of particles called protons, electrons and neutrons. ... A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. Protons and neutrons are both composed of other particles called quarks and gluons.

Particles can be atoms, molecules or ions. The term molecule is often used incorrectly to refer to any type of chemical compound. A molecule is a neutral particle made of two or more atoms bonded together. Take care with your own language, especially when referring to compounds formed during chemical reactions.

State one factor that effects the rate of change of the liquid colour

Debora [2.8K]

Answer:

Temperature is one of the major factors that affects the rate of change of the liquid colour, this is because ; like when if you freeze hot water the ice formed will be clear transparent, while on the other hand, if we freeze cold water it would be foggy inside the ice. This change occurs because of the temperature difference of the cold and hot water.

What is the scaling factor if the molar mass of

Step2247 [10]

Answer:

The scaling factor is 5.

Explanation:

Hello there!

In this case, since the scaling factor is defined as the ratio of the molar mass of the molecular formula (complete) to the empirical formula (simplified), it is possible to compute it for the empirical formula of CH2O whose molar mass is 30 g/mol (12+2+16) as shown below:

$sf=150/30=5$

Therefore, we can also infer that the molecular formula would be:

$C_5H_1_0O_5$

What mass of sucrose needs to be dissolved in 540 g of water in order to prepare a 15% by mass solution.

Lilit [14]

Answer:

95.3g

Explanation:

Given parameters:

Mass of water = 540g

Percentage by mass of solution = 15%

Unknown:

Mass of sucrose = ?

Solution;

To solve this problem, we must understand that a solution is made up of solute dissolved in a solvent. A solute is the solid dissolved in another. The solvent is the is dissolving medium;

Percentage by mass of solute in solution = $\frac{Mass of solute}{Mass of solution} x 100$

Mass of solution = mass of water + Mass of sucrose = 540 + M

where M is the mass of sucrose;

therefore;

$\frac{M}{540 + M } x 100$ = 15

Solving for M gives 95.3g

Mass of sucrose is 95.3g
