An object accelerates 3.0 m/s2 when a force of 6.0 Newton’s is applied to it. What is the mass of the object?
Alekssandra [29.7K]

Answer:2kg

Explanation:

Mass =?

Acceleration = 3.0 m/s2

Force = 6.0N

Force = Mass x Acceleration

6 = Mass x 3

Mass =6/3 = 2Kg

How many moles of BCl3 are needed to produce 10.0 g of HCl(aq) in the following reaction? (HCl molar mass is 36.46 g/mol).
Scilla [17]

Answer:

Moles of BCl₃ needed = 0.089 mol

Explanation:

Given data:

Moles of BCl₃ needed = ?

Mass of HCl produced = 10.0 g

Solution:

Chemical equation:

BCl₃ + 3H₂O  →     3HCl + B(OH)₃

Number of moles of HCl:

Number of moles = mass/molar mass

Number of moles = 10.0 g/ 36.46 g/mol

Number of moles = 0.27 mol

Now we will compare the moles of HCl with BCl₃.

               HCl             :           BCl₃

                 3               :             1

             0.27             :            1/3×0.27 = 0.089 mol

In two or more complete sentences describe all of the van der Waals forces that exist between molecules of sulfur
zavuch27 [327]

Answer:

Dipole-Dipole attraction

Explanation:

Dipole-dipole attraction is a type of vander waals forces found in the molecules of sulfur dioxide.

Vander waals forces are weak attractions joining non-polar and polar molecules together. They are of two types:

  • London dispersion forces which are weak attractions found between non-polar molecules.
  • Dipole-Dipole attraction are the forces of attraction which exists between polar molecules. Such molecules have permanent dipoles. This implies that the positive pole of one molecule attracts the negative pole of another. This is what happens between the oxygen and sulfur molecules.

Which nuclear emission moving through an electric field would be deflected toward the positive electrode?
Tom [10]
As a rule, opposite charges attract. So,you would expect that the particle that would deflect towards the positive electrode has a negative charge. Now, an alpha particle is basically a neutral Helium atom. Beta particle is an electron. Gamma particle has no charge (neutral). <em>Thus, the answer is B.</em>

The combustion of propane is best described as an
GalinKa [24]
<h3><u>Answer;</u></h3>

Exothermic chemical reaction

<h3><u>Explanation;</u></h3>
  • Exothermic reactions are chemical reactions where the products have less energy that the reactants.
  • Exothermic reactions give off energy, usually in the form of heat, while endothermic reactions absorb energy.
  • The combustion of propane is definitely an exothermic reaction because it generates a lot of heat.
