Answer:

The correct option is;

Scientist propose explanations that can be explained by examining evidence

Explanation:

A scientists makes an hypotheses based on possible natural processes to explain the origin and/or the nature of the characteristics of a natural observation. The scientist then source more data and information to put their hypotheses to test. Due to the fact that an hypotheses is based on observable  processes and/or mechanisms, the given hypotheses can be further tested by other scientists through the use of their individually sourced data. From the result of the assessment, the hypotheses can be either accepted or rejected to enable the better clarification of the hypotheses when accepted or the development of a new hypotheses when rejected.

Help needed urgently<br>the word missing or partially seen is oxygen ​ I forgot to put more pointa
butalik [34]

Explanation:

2.04 % hydrogen

32.65% sulphur

65.31% is oxygen

atomic ratio

hydrogen =2.04÷1=2.04

sulphur =32.65÷32=1.02

oxygen =65.31÷16=4.08

simplest ratio

hydrogen = 2.04÷1.02=2

sulphur =1.02÷1.02=1

oxygen =4.08÷1.02=4

empirical formula is H2SO4

Consider the combustion of octane:
just olya [345]

Answer:

15.9 g

Explanation:

(Take the atomic mass of C=12.0, H=1.0, O=16.0)

no. of moles = mass / molar mass

no. of moles of octane used = 11.2 / (12.0x8 + 1x18)

= 0.0982456 mol

Since oxygen is in excess and octane is the limiting reagent, the no. of moles of H2O depends on the no. of moles of octane used.

From the balanced equation, the mole ratio of octane : water = 2:18 = 1: 9,

so this means, one mole of octane produced 9 moles of water.

Using this ratio, we can deduce that (y is the no. of moles of water produced):

\frac{1}{9} =\frac{0.0982456}{y}

y = 0.0982456x9

y= 0.88421 mol

Since mass = no. of moles x molar mass,

mass of water produced = 0.88421  x (1.0x2+16.0)

=15.9 g

Which substances are broken down by chemical means
solniwko [45]

Compounds

Explanation:

Compounds are substances that can be broken down by chemical means. They are categorized as pure substances due to their definite composition.

  • Compounds are substances composed of two or more kinds of atoms or elements joined together in a definite grouping.
  • Properties of compounds differs from those of the constituent atoms.
  • Compounds are broken down by chemical means because they are products of chemical changes.
  • Several kinds of compounds exists through combinations of atoms.
  • Compounds have definite compositions
