Answer:Rate of change of Velocity per unit time” & definition of Velocity is “Rate of change of Distance per unit Time”. It means that , when acceleration is 0 then , velocity is constant. In short whatever may be the Velocity, if it remains constant then we say that acceleration is zero.
Answer:
It depends on whether the setting is hot or cold .-.
Explanation:
False They can function as both. An example is Aluminium Oxide. These kind of substances are called "Amphoteric", they can behave as both acids and bases.
Some electric appliances can be immersed in water without damage because they are well insulated. The electrical systems are well insulated and tightly sealed so that when they are immersed in water, no water can get into the electrical parts.
The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.
The moles of reactant and product in a chemical reaction to the whole number ratio is given by the stoichiometric coefficient of the balanced chemical equation.
<h3>Computation for the moles of oxygen</h3>
The balanced chemical equation for the reaction is :
From the balanced chemical equation, the 2 moles of acetylene react with 5 moles of oxygen.
The moles of oxygen react with 1 mole of acetylene are:
The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.
