1) What gives an objedt gravity?
Reptile [31]

1) the mass of an object gives gravity, the more massive an object is the more gravity it has on the things around it

2)the earth's mass is so much greater than our own that we feel it's gravity stronger than say the moon which has a smaller mass than the earth

3) mass and how far away you are from the object

4)as mass increases so does gravity (sorry I do not remeber the equation but there are some specific ones for different situations between two massive objects)

5) when distance increases, gravity decreases (again I do not remeber by how much)

Use Boyle’s law to complete the following:
mixas84 [53]

Answer:

The answer to your question is: 0.25 l

Explanation:

Data

P1 = 1 atm

V1 = 0.5 l

P2 =2 atm

V2 = ?

T = constant

Formula

          V1P1 = V2P2

Clear V2 from the formula

            V2 = V1P1/P2

Substitution

            V2 = (0.5)(1)/2  substitution

                  = 0.25 l       result

The rate constant for a certain reaction is k = 6.50×10−3 s−1 . If the initial reactant concentration was 0.600 M, what will the
Kamila [148]

Answer: 1.037M

Explanation:

Since the rate constant unit is per seconds, therefore it is a first order reaction.

First order reaction equation is given as

InA= -kt +InAo

Where,Ao is the initial concentration of reactant =0.600M

A is the concentration of reactant at a specifies time t=3×60=180s

and k is the rate constant

InA = -6.50×10^-3 ×180 +In(0.6)

InA = -1.17 + 0.5108

InA= -1.680

A = e-1.680

A= 1.037M

Therefore the concentration after 3minutes is 1.037M

Difne substitution reaction with example​
alisha [4.7K]

Answer:

A substitution reaction is also called a single displacement reaction, single replacement reaction, or single substitution reaction. Examples: CH3Cl reacted with a hydroxy ion (OH-) will produce CH3OH and chlorine. This substitution reaction replaces the chlorine atom on the original molecule with the hydroxy ion.

Hope it helps!!!
