A chemistry student combines 23.0 grams of sodium and 71.0 grams of chloride to form sodium chloride. According to the law of co
Diano4ka-milaya [45]

Answer:

94.0 g.

Explanation:

Hello!

In this case, since the lay of conservation of mass states that energy cannot be neither created nor destroyed, during a chemical reaction it is seen that the reactions undergo a change by which bonds can be broken or formed depending on the case. Thus, for the formation of sodium chloride we evidence the formation of the Na-Cl bond which means sodium is combined with chlorine according to the following chemical reaction:

2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)

It means that the reuslting mass of product is:

m_{NaCl}=23.0+71.0g=94.0g

Best regards!

I need help with with number 1515. How many moles of NO2 are in a 37.058 L container at 101.28 kPa and -139.86
Andre45 [30]

Explanation:

To solve this question, we will use the Clayperon Equation:

P.V = n.R.T

where:

P = 101.28 kPa

1 atm = 101,325 Pa

x atm = 101,280 Pa

x = 1 atm

V = 37.058 L

n = we don't know

R = 0.082 atm.L/K.mol

T = -139.88 ºC = -139.88+273.15 = 133.27 K

1*37.058 = n*0.082*133.27

n = 0.29 moles

Answer: 0.29 moles
