Answer:
Always carry the microscope with two hands. One on the arm and one underneath the base of the microscope.
There are different kinds of reactions. To name some, these are the synthesis reaction, decomposition reaction, single-replacement reaction, double-replacement reaction, combustion reaction, redox reaction, etc. For this type of reaction involving two reactants to yield only one product, <em>this is a synthesis reaction.</em>
<em>P₄ (s) + 6 Ca (s) --> 2 Ca₃P₂ (s)</em>
Answer:
The reaction is shifted to the left.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
- When there is a decrease in pressure, the equilibrium will shift towards the side with more no. of moles of gas molecules of the reaction.
- The reactants side (left) has 4.0 moles of gases and the products side (right) has 2.0 moles of gases.
- So, decreasing the pressure will shift the reaction to the side with more moles of gas (left side).
- <em>so, the reaction is shifted to the left.</em>

Answer:
c2h6
Explanation:
this is because c2h6 is a ethane having two carbon being bounded to 3 hydrogen each. making it to have two molecules . for they are on group alkenes which contains two molecule.
Answer:
the precise location of electrons at a specific time is unknown
Explanation:
The electron cloud model states that an electron’s position is uncertain, and does not revolve around the nucleus along a set course, as proposed by Bohr.
