Answer: Option (A) is the correct answer.

Explanation:

According to collision theory, more is the number of collisions between molecules of reactants more will be the rate of reaction.

Therefore, when we increase stirring in a beaker then it will create disturbance between the reactant molecules due to which there will be increase in number of collisions.

Hence, we can conclude that effect of stirring the given mixture on the system will be that the number of particle collisions increases.

An object has a density of 20.00 g/mL. If the object has a volume of 50.00 mL, what is its mass?
LuckyWell [14K]

Answer:

<h3>The answer is 1000 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of object = 50 mL

density = 20 g/mL

We have

mass = 20 × 50

We have the final answer as

<h3>1000 g</h3>

Hope this helps you

In lab you reacted 60 grams of propane (C3H8) with 13 grams of oxygen gas (O2). Your
Andre45 [30]

Answer:

120g

Explanation:

Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.

Thus, we need to convert mass of water to moles using its molar mass:

Moles H2O (Molar mass: 18g/mol):

63g H2O * (1mol / 18g) = 3.5 moles H2O

Converting to moles of CO2:

3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2

Mass CO2 (Molar mass: 44g/mol):

2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released

<h3>120g </h3>

Like several other bonds, carbon-oxygen bonds have lengths and strengths that depend on the bond order. Draw Lewis structures fo
aniked [119]

The order of increasing C-OC−O bond length is:

                 a < c < b < e < d

                  a < c < b < e < d

Therefore, the order of increasing bond strength is:

       d < e < b < c < a

        d<  e < b < c  < a

<h3>What is bond length?</h3>

The distance between the centers of two atoms that are covalently connected is known as the bond length. The number of bound electrons determines the bond's length (the bond order). The greater the attraction between the two atoms and the shorter the bond length are, the higher the bond order.

The average distance between the nuclei of two bound atoms in a molecule is referred to as bond length or bond distance in molecular geometry. It is a transferrable characteristic of a bond between atoms of fixed kinds that is comparatively independent from the other components of the molecule.

Bond length and bond order are related; the shorter the bond is when more electrons are involved in its production.
