A lab technician needs to create 570.0 milliliters of a 2.00 M solution of magnesium chloride (MgCl2). To make this solution, ho
vekshin1

Hey there!:

Molar mass MgCl2 = 95.211 g/mol

Volume of solution in liters:

570.0 mL / 1000 => 0.57 L

Number of moles:

n = M * V

n = 2.00 * 0.57 => 1.14 moles of MgCl2

Therefore:

1 mol MgCl2 --------------- 95.211 g

1.14 moles MgCl2 ---------- ??

mass of MgCl2 = 1.14 * 95.211

mass of MgCl2 = 108.54 g


Hope that helps!

What is scientific method? a. A plane for forming a scientific hypothesis. b. A technique for carrying out a scientific explemen
victus00 [196]

Answer:

d. An organized way to test scientific ideas

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

A scientific method can be defined as a research method that typically involves the use of experimental and mathematical techniques which comprises of a series of steps such as systematic observation, measurement, and analysis to formulate, test and modify a hypothesis.

A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.

Thus, for any hypothesis to be true and acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

In conclusion, we can deduce from the aforementioned paragraphs that a scientific method is simply an organized way to test scientific ideas and hypothesis.

Give the reason for the evaporation of the solution to dryness with 6 m hcl in the first procedure of the copper-arsenic group a
SCORPION-xisa [38]
<span>
Evaporation occurred between the reaction of the hydrochloric acid and the arsenic group because there is a formation of gas. A liquid is cooled if condensation exceeds evaporation. This is because the cooling of the liquid decreases the kinetic energy of the molecules. Their movement is being restricted by the colder temperature. The molecules tend to be closer with each other. Also, because of their restricted movement, the liquid may turn into solid due the colder temperature. An example of this is the cooling of liquid water by placing it into the refrigerator into solid water (ice).</span>
