If 525 N of force is applied to a 4.5 kg mass, how fast will it accelerate?

Chemistry
1 answer:
wariber [46]3 years ago
4 0

Answer:

121.11m/s²

Explanation:

Given parameters:

Force   = 525N

Mass = 4.5kg

Unknown:

Acceleration  = ?

Solution:

From Newton's second law of motion, we can find the solution to this problem. Using the expression below:

       F  =  m x a

F is the force

m is the mass

a is the acceleration

      So'

              525  = 4.5 x acceleration

            Acceleration = 121.11m/s²

What substance is present in a solution consisting solely of electrolytes?
Debora [2.8K]
Electrolytes are substances which are capable of producing a solution that has the ability to conduct electricity. These electrolytes are formed from the dissociation of salts into ions. The positive ions are named cations while the negative ions are termed anions. 

Hence, the answer to these item is SALT. Salt are substances produced by the reaction of cations and anions.

Calculate the density of a sample of 1.00 mole of nh3 at 793mmhg and -9.00 c
xeze [42]

0.164 g/L is the density of a sample of 1.00 mole of NH_3 at 793mmhg and -9.00 degrees celcius.

<h3>What is density?</h3>

Density is the mass of a unit volume of a material substance. The formula for density is d = \frac{M}{V}, where d is density, M is mass, and V is volume.

Given data:

n = 1.00 mole

P=793 mm hg =1.04342 atm

T=-9.00 degree celcius = -9.00 + 273= 264 K

V=?

Using Ideal Gas Law equation:  

PV = n R T      

R = gas constant = 0.082057 L-atm/(mol-K)

(1.04342 atm)(V) = 5 X 0.082057 L-atm/(mol-K)  X 264 K

V = 103.67 Liters

Now calculate density:

Mole weight of NH_3 = 1.00 mole

So, the mass of NH_3 = 17.031 g

Density =  \frac{mass}{volume}  

Density =  \frac{17.031 g}{ 103.67 Liters}  

= 0.164 g/L

Hence, 0.164 g/L is the density of a sample of 1.00 mole of NH_3 at 793mmhg and -9.00 degrees celcius.

How would you prepare 500 ml of the following solutions : Sodium succinate buffer (0.1 mol/dm3 pH 5.64)
Nana76 [90]

Answer:

8.10g of sodium succinate must be added and 247mL of 0.1M HCl adding enough water until make 500mL

Explanation:

<em>Succinic acid has a pKa₂ of 5.63</em>

To solve this question we must find the amount of sodium succinate and 0.1M HCl that we have to add using H-H equation:

pH = pKa + log [A-] / [HA]

5.64 = 5.63 + log [Na₂Succ.] / [HSucc⁺]

0.01 = log [Na₂Succ.] / [HSucc⁺]

1.0233 = [Na₂Succ.] / [HSucc⁺] <em>(1)</em>

As:

0.1M = [Na₂Succ.] + [HSucc⁺] <em>(2)</em>

Replacing (2) in (1):

1.0233 = 0.1M - [HSucc⁺] / [HSucc⁺]

1.0233[HSucc⁺] = 0.1M - [HSucc⁺]

2.033[HSucc⁺] = 0.1M

[HSucc⁺] = 0.0494M

[Na₂Succ] = 0.0506M

Both [Na₂Succ⁺] and [HSucc⁺] ions comes from the same sodium succinate we have to find the moles of sodium succinate in 500mL of 0.1M. Then, based on the reaction:

Na₂Succ + HCl → HSucc⁺ + Cl⁻

The moles of HCl added = Moles HSucc⁺ we need:

<em>Moles Na₂Succ:</em>

0.500L * (0.1mol/L) = 0.0500 moles

<em>Mass -Molar mass sodium succinate: 162.05g/mol-:</em>

0.0500mol * (162.05g/mol) = 8.10g of sodium succinate must be added

<em>Moles HCl:</em>

0.0494M * 0.500L = 0.0247 moles HCl * (1L / 0.1mol) = 0.247L =

And 247mL of 0.1M HCl adding enough water until make 500mL
