Answer:

D. B, C, A

Explanation:

A. For object A, given the following data;

Mass = 2kg

Net force = 1N

To find the acceleration;

Acceleration = net force/mass

Acceleration = 1/2

<em>Acceleration = 0.5m/s²</em>

B. For object B, given the following data;

Mass = 8kg

Net force = 10N

To find the acceleration;

Acceleration = net force/mass

Acceleration = 10/8

<em>Acceleration = 1.25m/s²</em>

C. For object C, given the following data;

Mass = 7kg

Net force = 7N

To find the acceleration;

Acceleration = net force/mass

Acceleration = 7/7

<em>Acceleration = 1m/s²</em>

Therefore, placing the objects in decreasing order, according to the magnitude of the acceleration they are experiencing is B, C, A

Answer:

The correct answer is - 14.

Explanation:

In the given molecular formula of the aluminum sulphite which is Al2(SO3)3, this molecular formula there different type of elements are bonded together to form this compound each element has a specific number of atoms present. This compound has three elements that are aluminum, sulfur, and oxygen and the atoms are present are:

Al = 2 atoms represented by subscript

S = 3 atoms represented as whole subscripts of sulfite

O = 9 atoms 3 inside bracket and 3 outside of bracket that multiplies.

Thus, total number of atoms are 2+3+9 = 14

mylen [45]

Answer:

5.4

Explanation:

V1=5.0

T1=25+ 273=298

V2= z(unknown)

T2=5+273=278

V1/T1 =V2/T2

V2=V1T2/T1

=5*298/278

=5.4

I have these orgo problems for homework and I have no idea where to even begin. We have to find missing reagents and products ba
almond37 [142]

Answer:

Honestly makes no sense sorry :(

Explanation:

I can try though.. There are three types of selectivity possible for any synthesis: (i) Chemoselectivity is deciding which group reacts. (ii) Regioselectivity is where the reaction takes place in that group. (iii) Stereoselectivity is how the group reacts with respect to the stereochemistry of the product.

A stereospecific mechanism specifies the stereochemical outcome of a given reactant, whereas a stereoselective reaction selects products from those made available by the same, non-specific mechanism acting on a given reactant. Of stereoisomeric reactants, each behaves in its own specific way.

I tried to explain it the best I could.

Hopefully this helps you :)

Feel free to correct me If it was wrong
