Inessa [10]

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

A 12400. mL container holds a sample of argon gas at 35.00C and
xz_007 [3.2K]

Answer:

0.574moles

Explanation:

Using the general gas equation;

PV = nRT

Where;

P = pressure (atm)

V = volume (Litres)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (Kelvin)

According to the information provided in the question;

- Volume (V) = 12400mL = 12400/1000 = 12.4L

- Pressure (P) = 890mmHg = 890/760 = 1.17atm

- Temperature (T) = 35°C = 35 + 273 = 308K

Hence, using PV = nRT

n = PV/RT

n = 1.17 × 12.4 ÷ 0.0821 × 308

n = 14.508 ÷ 25.287

n = 0.574moles

Therefore, the number of moles of argon gas in the cylinder is 0.574moles

A compound is known to consist solely of carbon, hydrogen, and chlorine. Through elemental
OleMash [197]

Answer:

the empirical (lowest raios) is

C2H4Cl    

Explanation:

A compound is known to consist solely of carbon, hydrogen, and chlorine. Through elemental analysis, it was determined that the compound is composed of 24.27% carbon.

What is the empirical formula of this compound?

the compound has ONLY C, H, and Cl

the % Cl  = 100% - 24.27% -4.03% = 71.7%

in 100 gm, there are 71.7 gm Cl, 24.27 gm C, and 4.03 gm H

the number of moles are Cl=71.7/70.91 =1.01= ~ 1

                                          C = 24.27/12.0 = 2.02 =~ 2

                                           H = 403/1.01 = 3.97 =~   4

so   the empirical (lowest raios) is

C2H4Cl
