Answer:
true
covalent bonds are between non metals and nonmetals. and they are sharing electrons.
Answer:
To express the efficiency of a reaction, you can calculate the percent yield using this formula: %yield = (actual yield/theoretical yield) x 100. A percent yield of 90% means the reaction was 90% efficient, and 10% of the materials were wasted (they failed to react, or their products were not captured).
Explanation:
If a substance is reduced, it must undergo a gain of hydrogen or a loss of oxygen.
Reduction
Redox reactions include a change in the oxidation state of the substrate.
Loss of electrons or a rise in an element's oxidation state is considered to be oxidation.
Gaining electrons or lowering the oxidation state of an element or its constituent atoms are both examples of reduction.
Redox reactions fall into one of two categories:
A single electron is transferred from the reducing agent to the oxidant in this process. The terminology used to describe this kind of redox reaction is frequently redox couples and electrode potentials.
A process called atom transfer involves moving an atom from one substrate to another. For instance, as iron rusts, the oxidation state of the iron atoms increases as it transforms into an oxide, while oxygen's oxidation state falls as oxygen receives the electrons released by the iron. Other chemical species can perform the same function, despite the fact that oxidation reactions are frequently linked to the production of oxides. In hydrogenation, hydrogen atoms are transferred in order to weaken C=C bonds.

<span>The correct answer is ideal gas law.
when the ideal gas law formula is:
PV = nRT ,
when P is the pressure.
V is the volume.
and R is the ideal gas constant.
T is the temperature.
and n is the number of moles.
So, this is the law which relates pressure, temperature, volume and number of moles . and this law state that 1 mole of an ideal gas will occupy a volume V = 22.4 L</span>
Standard Temperature and Pressure (STP) is 0 degree Celsius and 1 atm. We also know that 1atm= 101.3 kPa. Thus, set 3 is the best choice.
Hope that would help :))
